Full Text Available BACKGROUND: Little information is available about infantile visceral leishmaniasis (VL in Albania as regards incidence, diagnosis and management of the disease. METHODOLOGY/PRINCIPAL FINDINGS: Demographic data, clinical and laboratory features and therapeutic findings were considered in children admitted to University Hospital of Tirana from 1995 to 2009, and diagnosed as having VL. The diagnosis was based on bone-marrow microscopy/culture in 77.5% of patients, serology in 16.1%, and ex juvantibus in 6.4%. A total of 1,210 children were considered, of whom 74% came from urbanized areas. All patients were in the age range 0-14 years, with a median of 4 years. Hepatosplenomegaly was recorded in 100%, fever in 95.4% and moderate to severe anemia in 88% of cases. Concomitant conditions were frequent: 84% had bronchopneumonia; diarrhea was present in 27%, with acute manifestations in 5%; 3% had salmonellosis. First-line therapy was meglumine antimoniate for all patients, given at the standard Sb(v dosage of 20 mg/kg/day for 21 to 28 days. Two children died under treatment, one of sepsis, the other of acute renal impairment. There were no cases of primary unresponsiveness to treatment, and only 8 (0.67% relapsed within 6-12 months after therapy. These patients have been re-treated with liposomal amphotericin B, with successful cure. CONCLUSIONS: Visceral leishmaniasis in pediatric age is relatively frequent in Albania; therefore an improvement is warranted of a disease-specific surveillance system in this country, especially as regards diagnosis. Despite recent reports on decreased responses to antimonial drugs of patients with Mediterranean VL, meglumine antimoniate treatment appears to be still highly effective in Albania.

Full Text Available This article discusses the development of transport inequalities in Tirana during its rapid population and economic growth since the fall of communism in 1990. The first part provides background on the development of Tirana and its urban travel systems, in an effort to take a step towards filling the research void on this city. Tirana’s case is particularly interesting because during communism private car ownership was prohibited and there were virtually no cars on the streets. Subsequently, when the population acquired wealth and personal freedom, the city grew substantially in all directions and was invaded by car traffic. The second part of this article analyses the findings of recent transportation surveys, conducted by this author, with a focus on the transport disadvantage that women, children, the poor, the elderly, and the handicapped experience. This discussion is preceded by a brief review of studies reflecting the emergence of concerns about transport inequality issues in other European nations during the past few decades. The article concludes with policy recommendations based on public opinions on transport issues, collected through the author’s surveys.

We aimed to assess the extent and the socioeconomic correlates of witnessed parental physical violence among university students in Albania, a country in transition from rigidly structured socialism to a market-oriented system. 2797 students (93% of all students) at the Medical Faculty, Tirana, filled out an anonymous structured questionnaire in April-June 2009. Information on witnessed father-to-mother physical violence during childhood and/or adolescence and sociodemographic and socioeconomic data were collected. The association of witnessed parental violence with socioeconomic factors was assessed with multivariable-adjusted logistic regression. 736 (26.7%) of students witnessed father-to-mother physical violence, and 36 (1.3%) reported 'very often' witnessing episodes. In multivariable-adjusted models, independent predictors of witnessed violence were: low family income [odds ratio (OR) = 2.4, 95% confidence interval (CI) = 1.7-3.2], rural origin (OR = 1.9, 95% CI = 1.5-2.5), father's lower education and unemployment (OR = 5.4, 95% CI = 4.1-7.1 and OR = 2.5, 95% CI = 1.9-3.2, respectively) and mother's educational and employment advantage compared with the spouse (OR = 2.7, 95% CI = 1.9-3.8 and OR = 2.2, 95% CI = 1.6-2.8, respectively). Father's socioeconomic disadvantage and mother's socioeconomic empowerment were each independently related to increased risk for witnessed father-to-mother physical violence among university students in this transitional patriarchal society. Health professionals in post-communist Albania should be aware of the ways in which witnessed domestic violence influences physical and psychological health of young adults.

Full Text Available The real estate market is complex and influenced by too many factors. Real Estate market in Albania has experienced a boom after the 1990. We have inherited from the communist system a very poor market of housing. The number of dwellings in 1990 in Albania was 219 dwellings per 1000 inhabitants and the useful floor space was 5 m² per person, but in Bulgaria number of dwellings per 1,000 people varies 465 and in Romania average useful floor space per person was 37 sq. The data used in this study are derived from the database of the World Bank, the Institute of Statistics, reports of Bank of Albania also from information provided individually on the ground and different sources. In this study is analyzed the relationship that exists between economic growth, remittances and the price of dwellings in Albania. The dependent variable is the average price of housing in major cities of Albania. Independent variables in the model are GDP per capita and the remittances. The Econometric model is a Linear Regress equation and the period are the years from 1998 to 2013. The model used is the statistical program EViews 6.0. Unfortunately the information let the desired, so we do not have an official detailed information on prices of Albanian real estate market. In Albania few researchers have been studying real estate market in Albania.

Full Text Available Internationalization of higher education in Albania although an emerging necessity is still in very low figures not only as a connection between institutions but even as mobility between students. This paper sheds lights on internationalization at the regional and at the global level. It analyzes how the globalization and European integration processes are affecting public and private higher education institutions in Albania, their study programs and universities internal management structures. Firstly, it examines the overall changes in the Albanian HE sector since the beginning of 1990s. Then it explores the differences in internationalization between public and private universities and the ultimate changes on the Albanian labor market. My main thesis is that Albanian HE institutions increasingly need to put more efforts to internationalize their internal management structures and to put in practice international study programs. The paper analyzes more the advantages of the international study programs and the difficulties in a development country like Albania to implement them. The paper is based on the case study of the European University of Tirana and explores the difficulties of the faculties of this university to find financial support for international programs, research and travelling abroad, to develop courses with one international perspective, support for its students to study abroad, support to students from other countries and on other indicators such as grants, contracts and linkages in international areas. However the paper deals also with the academic requirements the issue of quality of universities in general. At the end the paper makes a prognosis of some strategies and gives some recommendations how to integrate the Albanian higher education institutions at a regional or global level.

Our aim was to validate an international instrument measuring self-perceived competency level of family physicians in Albania. A representative sample of 57 family physicians operating in primary health care services was interviewed twice in March-April 2012 in Tirana (26 men and 31 women; median age: 46 years, inter-quartile range: 38-56 years). A structured questionnaire was administered [and subsequently re-administered after two weeks (test-retest)] to all family physicians aiming to self-assess physicians' level of abilities, skills and competencies regarding different domains of quality of health care. The questionnaire included 37 items organized into 6 subscales/domains. Answers for each item of the tool ranged from 1 ("novice" physicians) to 5 ("expert" physicians). An overall summary score (range: 37-185) and a subscale summary score for each domain were calculated for the test and retest procedures. Cronbach's alpha was used to assess the internal consistency for both the test and the retest procedures, whereas Spearman's rho was employed to assess the stability over time (test-retest reliability) of the instrument. Cronbach's alpha was 0.87 for the test and 0.86 for the retest procedure. Overall, Spearman's rho was 0.84 (Pcross-cultural adaptation of an international instrument taping self-perceived level of competencies of family physicians in Albania. The questionnaire displayed a satisfactory internal consistency for both test and retest procedures in this sample of family physicians in Albania. Furthermore, the high test-retest reliability (stability over time) of the instrument suggests a good potential for wide scale application to nationally representative samples of family physicians in Albanian populations.

To assess the association of leisure-time exercise and television (TV) viewing, a sedentary marker, with acute coronary syndrome (ACS) in Albania, a transitional country in Southeast Europe. A population-based case-control study was conducted among Tirana residents in 2003-2006. Information on leisure-time exercise (transformed into kilocalories of energy expenditure) and daily hours of TV viewing was obtained by interviewer-administered questionnaire. 460 non-fatal ACS patients (368 men, 92 women) and 628 coronary heart disease-free controls (413 men, 215 women) were studied. Adjusted for socio-demographic characteristics, conventional coronary risk factors and leisure-time exercise, TV viewing was associated with ACS in women (OR=1.66, 95%CI=1.12-2.46 per hour/day viewing), but not in men (OR=0.93, 95%CI=0.81-1.07; P for sex-interaction=0.02). A low level of leisure-time exercise (adjusted also for TV viewing) was associated with ACS similarly in men and women (pooled sexes OR=2.03, 95%CI=1.29-3.22 for bottom vs top tertile of energy expenditure). Leisure-time inactivity is confirmed as an important risk factor for ACS also in Southeastern Europe. TV viewing may be an informative coronary risk marker in transitional societies, especially in women.

Full Text Available Background: Histocompatibility testing (HT which includes donor-recipient human leukocyte antigen (HLA matching, cross-match testing (XMT and anti-HLA antibody searching are crucial examinations in solid organ transplantation aiming to avoid the hyperacute graft rejection and also to predict the immunological outcome of the graft. Aims: The aim of this study was to analyse the tissue typing data collected at the Laboratory of Immunology and Histocompatibility of the University Hospital Center of Tirana, Albania, in order to define those actions that should be taken for improvements in the situation of kidney transplantation in Albania. Design: Descriptive study. Methods: The donor/recipient cross-match testing was performed through a standard complement-dependent cytotoxicity (CDC assay using separated donor T and B cells that were tested in parallel with the recipient serum sample. All recipient sera were screened for anti-Class I and anti-Class II HLA antibodies using a bead based Luminex anti-HLA antibody screening test. In the case of detected positivity, an allele-specific anti-HLA antibody determination was conducted with the respective Luminex anti-Class I and Class II HLA antibody determination kits. Results: A total of 174 recipients and 202 donors were typed for the purpose of living donor kidney transplantation at our laboratory between January 2006 and December 2012. The mean age and female gender proportion of patients were 34.9 years and 34.5%, respectively, and 48.0 years and 65.3% for the donors, respectively. Here, 25.9% of the patients reported a positive complement-dependent cytotoxicity cross-match test and/or a positive anti-HLA antibody testing result. Eighteen patients that were negative for the complement-dependent cytotoxicity cross-match test were positive for anti-HLA antibodies. Conclusion: The predominant causes of end-stage renal disease (ESRD in our patient population are chronic pyelonephritis and

Dalvi, Ambalika Rajendra

Improving the conditions of schools in many parts of the world is gradually acquiring importance. The Green School movement is an integral part of this effort since it aims at improving indoor environmental conditions. This would in turn, enhance student- learning while minimizing adverse environmental impact through energy efficiency of comfort-related HVAC and lighting systems. This research, which is a part of a larger research project, aims at evaluating different school building designs in Albania in terms of energy use and indoor thermal comfort, and identify energy efficient options of existing schools. We start by identifying three different climate zones in Albania; Coastal (Durres), Hill/Pre-mountainous (Tirana), mountainous (Korca). Next, two prototypical school building designs are identified from the existing stock. Numerous scenarios are then identified for analysis which consists of combinations of climate zone, building type, building orientation, building upgrade levels, presence of renewable energy systems (solar photovoltaic and solar water heater). The existing building layouts, initially outlined in CAD software and then imported into a detailed building energy software program (eQuest) to perform annual simulations for all scenarios. The research also predicted indoor thermal comfort conditions of the various scenarios on the premise that windows could be opened to provide natural ventilation cooling when appropriate. This study also estimated the energy generated from solar photovoltaic systems and solar water heater systems when placed on the available roof area to determine the extent to which they are able to meet the required electric loads (plug and lights) and building heating loads respectively. The results showed that there is adequate indoor comfort without the need for mechanical cooling for the three climate zones, and that only heating is needed during the winter months.

Serum samples collected from 167 equines of 12 districts in Albania were tested for West Nile virus-specific antibodies by enzyme-linked immunosorbent assay and virus neutralization assay, using WNV lineage 1 and 2. In addition, 95 bird serum samples from Albania and 29 horse samples from Kosovo were tested in ELISA. An overall seroprevalence rate of 22% was found in horses from Albania, whereas no specific antibodies were found in the equine samples from Kosovo and the bird samples. This is the first report indicating WNV infections in animals in Albania, and the first reported seroprevalence study conducted for Kosovo. These results provide evidence for widespread infections of WNV in Albania. © 2013 Blackwell Verlag GmbH.

This study examines socio-demographic profiles, injecting risk and use of health services among young injectors (15-24) in Albania, Moldova, Romania and Serbia. The objective was to provide age-disaggregated data to identify differences between adolescents (Romania, surveys were conducted in the capitals, respectively, Bucharest and Tirana. Respondents were recruited from 3 cities in Moldova (Chisinau, Balti and Tiraspol) and Serbia (Belgrade, Novi Sad and Nis). Data were collected on risk behaviours, service use and contact with police and other authorities. Analysis focused on associations between unsafe injecting behaviour and key determinants including demographic background, source of needles/syringes, use of harm reduction services and interactions with law enforcement. Although drug use and health-seeking varied across settings, sources of injecting equipment were significantly associated with sharing needles and syringes in Moldova, Romania and Serbia. Obtaining equipment from formal sources (pharmacies, needle-exchange programmes) reduced likelihood of sharing significantly, while being stopped by the police or incarcerated increased it. Adolescents relied on pharmacies more than public sector services to obtain equipment. Adolescents comprise a small proportion of PWID in this region, but have poorer access to harm reduction services than older peers. Engaging young PWID through private and public sector outlets might reduce unsafe practices, while use of the justice system to address drug use complicates efforts to reach this population.

Full Text Available Recent technological changes have had a great impact on the accounting and financial environment. As other countries Albania has also been affected by developments such as the evolution towards using accounting information packages, financial web reporting, XBRL and cloud computing. Throughout this paper we try to analyze the current situation of accounting and financial reporting in Albania and the impact that the web reporting has had on the simplification of the accounting procedures. We present how tools such as cloud computing and XBRL have impacted the use of the accounting systems and also other reporting institutions in Albania. Describing the current development of cloud services we give information on the part of software vendors in Albania. We find that cloud computing has been used extensively not only by the private companies offering accounting infomations systems, but also by other companies in the public sector (i.e. education. On the other hand we find that XBRL, even though a promising technology, has not been gained great recognition in Albania and is currently not used by any on the institutions or companies, neither by institutions whose mission is to create extensive databases (such as the Registrar of the Companies and which might benefit the most from this technology.

One hundred eighty-one dogs and 26 short-hair cats from suburban areas around Tirana, Albania were examined for ectoparasite infestation. The dogs were examined on several occasions from 2005 through 2009 representing three seasons: winter (December-February), spring (March-May), and summer (June-August); the cats were examined in late autumn (November). In addition, deep ear swab specimens of 30 dogs were examined for ear mites. The arthropod ectoparasite fauna of the dogs included two tick species (Rhipicephalus sanguineus and Ixodes ricinus), three mite species (Sarcoptes scabiei var. canis, Otodectes cynotis, and Demodex canis), three flea species (Ctenocephalides canis, Ctenocephalides felis, and Pulex irritans), and one louse species (Trichodectes canis). In the dogs, rates of infestation were 23.8% for R. sanguineus, 0.6% for I. ricinus, 4.4% for S. scabiei var. canis, 6.7% for O. cynotis, 0.6% for D. canis, 75.7% for C. canis, 5.0% for C. felis, 8.3% for P. irritans, and 6.6% for T. canis. Mixed infestation with two or three species of ectoparasites was recorded on 38.1% of the dogs. Fleas infested 75.7% dogs (geometric mean, 3.96; range, 1-80) and were observed in winter, spring, and summer with increasing prevalences of 64.3%, 75.9%, and 100%. Ticks parasitized 24.3% of the dogs (geometric mean, 0.41; range, 1-331). R. sanguineus ticks were recorded on 34.2% and 50% of the dogs examined in spring and summer, respectively, but were absent on the dogs during winter except for a single I. ricinus specimen observed. Prevalence of infestation with R. sanguineus, S. scabiei var. canis, C. felis, P. irritans, and T. canis did not differ between dogs 6 months of age; however, prevalence of infestation with C. canis was significantly (p 6 months old. There was no difference between the sexes for the prevalences of infestation with those parasites. The examination of the cats revealed infestation with only one species of ectoparasite, C. felis (prevalence, 100

We conducted a case-control study in Tirana in 2003-2006 including 467 non-fatal consecutive ACS patients (370 men aged 59.1±8.7 years, 97 women aged 63.3±7.1 years; 88% response) and a population-based control group (469 men aged 53.1±10.4 years, 268 women aged 54.0±10.9 years; 69% response). A semi-quantitative food frequency questionnaire including 105 food items was administered to all participants based on which the daily calorie intake for selected food groups (meat products, overall oils and fats, sweets, and junk food) was calculated. General linear model was used to assess the association of food groups with ACS. Mean age-adjusted values of meat products, overall oils and fats, sweets and junk food were all considerably higher in cases than controls in both sexes. Cases had significantly higher mean "non-Mediterranean" diet scores (consisting of junk food, sweets, oils and fats except olive oil) than controls (10.3% vs. 5.9% in men and 15.2% vs. 8.3% in women, Pconsumption of processed foods was associated with considerable excess coronary risk which points to serious health implications for the Albanian adult population.

Serbo-Albanian bank in Albania 1925-1927

Full Text Available The Serbo-Albanian Bank was founded at Cetinje in 1922, at the time Yugoslav-Albanian diplomatic relations were established, with the purpose of opening its branch offices in Albania in order to contribute to closer economic relations between the two neighboring countries. The Bank was unable to achieve its goal in the first two years of operation, as it had not obtained the necessary licenses from the Albanian authorities. The branch office in Scutari was opened only in early 1925. Another topical issue at the time was the creation of the Albanian National Bank as the central monetary institution that would function as a regulator of the entire economic life of Albania. Supported by the Yugoslav state, the Serbo-Albanian Bank planned its transformation into an Albanian central bank, but without success. Namely, it was Italian capital that assumed a leading role in the Albanian National Bank founded in September 1925. In spite of this failure, the branch office of the Serbo-Albanian Bank commenced its operations in Albania. Under its roof, it set up the Privileged Trading Agency, and expressed interest in obtaining exploration and excavation concessions for the copper mine in the region of Puka in northern Albania. It was granted the concession by the Albanian government, but failed to set up a copper exploitation company. Facing numerous difficulties, the major of which was lack of the necessary cash for operation and significant business losses in Albania, the branch office was closed in 1927, pursuant to the decision of the Cetinje headquarters.

Fear of falling (FoF) is a common health problem among older adults. Although the relationship between FoF and limitation in daily activities has been reported, FoF's relationship to mobility disability, a transitional phase to end-stage disability, is not yet understood. We examined the relationship between FoF and mobility disability among community-dwelling older adults and explored the differences in this relationship among socio-culturally diverse sites. Cross-sectional study. Community. 1875 participants (65-74 years) were recruited from five sites and included in the analysis (Kingston, Canada: 394; St-Hyacinthe, Canada: 397; Tirana, Albania: 359; Manizales, Colombia: 341; and Natal, Brazil: 384). FoF was quantified using the Falls Efficacy Scale-International (FES-I, range: 16-64). Mobility disability was defined as difficulty climbing a flight of stairs or walking 400m without assistance. Overall, 21.5% of participants reported high FoF (FES-I>27). The average FoF scores were significantly different between the sites (pfive study sites (ranged from 19.8% at Kingston, Canada to 50.7% at Tirana, Albania, pfive sites.

Conditioning of low level radioactive wastes, spent radiation sources and their transport at the interim storage building of the Institute of Nuclear Physics in Albania

International Nuclear Information System (INIS)

Qafmolla, L.

2000-01-01

Aspects of treatment and management of radioactive wastes resulting from the use of radiation sources and radioisotopes in research, medicine and industry, are described. The methods applied for the conditioning of low-level radioactive wastes and spent radiation sources are simple. Solid radioactive wastes with low-level activity, after accumulation, minimization, segregation and measurement, are burned or compressed in a simple compactor of the PGS type. Spent radiation sources are placed into 200 l drums, are cemented and conditioned. Conditioned drums from the Radiation Protection Division of the Institute of Nuclear Physics (INP), which is the responsible Institution for the treatment and management of radioactive wastes in Albania, are transported to the interim storage building of the Institute of Nuclear Physics in Tirana. Work to construct a new building for treatment and management of radioactive wastes and spent radiation sources within the territory of INP is underway. Funds have been allocated accordingly: based on the Law No. 8025 of 25.11.1995, it is the Albanian Government's responsibility to finance activities concerned with the treatment and management of radioactive wastes generating from the use of ionizing radiation in science, medicine and industry in the country.

Paci, Rustem; Ylli, Fatos

2008-01-01

The paper intends to present the evolution and actual situation of radiation protection and safety infrastructure in Albania, focusing in its establishing and functioning in accordance with BBS and other important documents of specialized international organizations. There are described the legal framework of radiation safety, the regulatory authority, the services as well the practice of their functioning. The issue of the establishing and functioning of the radiation safety infrastructure in Albania was considered as a prerequisite for a good practices development in the peaceful uses of radiation sources . The existence of the adequate legislation and the regulatory authority, functioning based in the Basic Safety Standards (BSS), are the necessary condition providing the fulfilment of the most important issues in the mentioned field. The first document on radiation protection in Albania stated that 'for the safe use of radiation sources it is mandatory that the legal person should have a valid permission issued by Radiation Protection Commission'. A special organ was established in the Ministry of Health to supervise providing of the radiation protection measures. This organization of radiation protection showed many lacks as result of the low efficiency . The personnel monitoring, import, transport, waste management and training of workers were in charge of Institute of Nuclear Physics (INP). In 1992 an IAEA RAPAT mission visited Albania and proposed some recommendations for radiation protection improvements. The mission concluded that 'the legislation of the radiation protection should be developed'. In 1995 Albania was involved in the IAEA Model Project 'Upgrading of Radiation Protection Infrastructure'. This project, which is still in course, intended to establish the modern radiation safety infrastructures in the countries with low efficiency ones and to update and upgrade all aspects related with radiation safety: legislation and regulations, regulatory

PUBLIC DEBT DETERMINANTS IN ALBANIA

Directory of Open Access Journals (Sweden)

Edlira Kalaja

2015-10-01

Full Text Available State budget is one of the most important instruments where the government reflects its future policies, priorities and commitments. Its reading in recent years clearly shows the increased size of public debt beyond the upper limit of 60% of GDP, in many countries including Albania. This fact constitutes analarming trend signaled even by many international financial institutions. However, the worldwide increasing levels of budget deficits and public debtsare not accidental. Through this article we aim to explore the relationships that exists between different determinants such as governance, social and economic variables that directly affect the size of public debt in Albania, where demographic factors are noted as the main contributors, followed by political systems along with various economic developments that the country has experienced in years.

Euthanasia in Albania

2016-03-01

Full Text Available The right to live is a right guaranteed by the constitution as well as international legal acts in force in a country, and is based on the moral of a society. But does the right to live imply a parallel individual right to die? Or should the state protect the right to life of a person who does not want to live anymore, going like this against the will of that person? Albanian anthropology, as a post-communist society lacks the tradition of freedom, as in this case of the freedom that belongs to a man affected by an incurable disease. For this reason, in Albania not only we do not have a law on euthanasia, but the issue of euthanasia is not raised as an issue nor by the legislator nor by civil society. The purpose of this paper is to give an overview of euthanasia in Albania, as well as on some specific problems facing the Albanian reality. The methodology used in the paper consists with the combination of comparing legal provisions of euthanasia (or the lack of them in a vertical historical continuity.

In the territory of Albania usually every year around 1000 ha are affected by forest fires, from which about 500 ha are completely destroyed. The number of forest fires (nf), with the burning surface (bs) in years has been like this: during the years 1988-1998: nf / bs = 2.19, 1998-2001: nf / bs = 5.66, year 2002 -2005: nf / bs = 8.2, and during the years 2005-2006: nf / bs = 11.9, while economic losses in a year by forest fires is about 2 million of Euro. The increase in years of these figures and the last floods which happened in the last two years in Shkoder, led to an international cooperation, that between the Italian Civil Protection Department and the Albania General Directorate of Civil Emergency. The focus of this cooperation was the building capacity of the Albanian National System of Civil Protection in forecasting, monitoring and prevention forest fires and floods risks. As a result of this collaboration the "National Center for the Forecast and Monitoring of Natural Risks", was set up at the Institute of Geosciences, Energy, Water and Environment. The Center is the first of its kind in Albania. The mission of the Center is the prediction and monitoring of the forest fire and flood risk in the Albanian territory, as a tools for risk reduction and mitigation. The first step to achieve this strategy was the implementation of the forest fires risk forecast model "RISICO". RISICO was adapted for whole Albania territory by CIMA Research Foundation. The Center, in the summer season, issues a daily bulletin. The bulletin reports the potential risk scenarios related with the ignition and propagation of fires in Albania. The bulletin is broadcasted through email or fax within 12.00 AM of each working day. It highlights where and when severe risk conditions may occur within the next 48 hours

2017-01-01

To establish the diversity and seasonality of ectoparasite infestation in client-owned dogs in Albania, 602 dogs visiting four small animal clinics in Tirana from March 2010 to April 2011 inclusive were examined for ectoparasites by full body search and total body comb. In addition, ear swab specimens collected from all dogs and scrapings taken from skin lesions suspicious of mite infestation were examined for parasitic mites. Overall, 93 dogs (15.4 %, 95%CI 12.6-18.6) were demonstrated to be infested, and nine species of ectoparasites were identified: Ixodes ricinus, 0.8 %; Rhipicephalus sanguineus s. l., 8.1 %; Demodex canis, 0.2 %; Sarcoptes scabiei, 0.7 %; Otodectes cynotis, 2.8 %; Ctenocephalides canis, 4.8 %; Ctenocephalides felis, 3.0 %; Pulex irritans, 0.2 %; and Trichodectes canis, 0.2 %. Single and multiple infestations with up to four species of ectoparasites concurrently were recorded in 67 (11.1 %, 95%CI 8.7-13.9) and 26 dogs (4.3 %, 95%CI 2.8-6.3), respectively. On univariate analysis, the category of breed (pure breed dogs vs. mixed-breed dogs), the dog's purpose (pet, hunting dog, working dog), the housing environment (mainly indoors/indoors with regular outside walking vs. yard plus kennel/run), the history of ectoparasiticide treatment and the season of examination were identified as significant (p < 0.05) factors predisposing dogs to various ectoparasites, while the variables dog's age, gender, the dog's habitat (city, suburban, rural) and the presence/absence of other pets were not significant predictors. Multivariate logistic regression analysis for factors associated with overall ectoparasitism revealed that dogs treated with ectoparasiticides at least once per year (odds ratio [OR] = 0.24; p < 0.001) had a significantly lower risk of infestation compared with dogs not treated against ectoparasite infestation. Dogs examined during spring, summer and autumn (OR = 7.08, 7.43 and 2.48, respectively; all p < 0

Full Text Available The euroisation issue in European Integration context, is a continuous process of discussions between different researchers and regulatory institutions. Nowadays, different aspects of collaboration and integration processes between countries in the region, are extended in all politics, economic and security dimensions. In this study, we are going to treat one of the aspects of this process integration for Albania: the possibility of substituting the Albanian Lek with Euro, beginning with the explanation of the concept of euroisation. Also we are going to identify the actual non-official replacement level of lek and how it is expected to be realized in the future. Albania like other developing countries is lack of a currency with which people can buy abroad and which can be used in short-run and long-run credit contracts. On the other hand, the exchange rate represents an important risk, especially for the business which realizes transactions in foreign currency. Here in we are focused on the measurement of the money replacement level in Albania through three main methods. For this purpose is used the regression analysis in order to test the hypothesis under evaluation in two directions: endogenous and exogenous potential factors affecting this replacement. Through the factor analysis identifying the pro and cons of the euroisation phenomenon, we will give the potential alternative in our county economy conditions. Finally, the replacement rate cannot be assessed without being related to the degree of money in circulation replacement and the degree of assets replacement and without being connected with the exchange rate between currencies.

From March 2010 to April 2011 inclusive, feces from 602 client-owned dogs visiting four small animal clinics in Tirana, Albania, were examined using standard coproscopical techniques including Giardia coproantigen ELISA and immunofluorescent staining of Giardia cysts. Overall, samples of 245 dogs (40.7 %, 95 % CI 36.6-45.6) tested positive for at least one type of fecal endoparasite (protozoan and/or helminth and/or pentastomid) stage, of which 180 (29.9 %, 95 % CI 26.3-33.7) and 129 (21.9 %, 95 % CI 18.2-24.9) tested positive for protozoan or nematode endoparasites, respectively. Fecal forms of at least 14 endoparasites were identified. The most frequently identified stages were those of Giardia (26.4 %), Trichuris (9.5 %), Toxocara (8.0 %), hookworms (7.1 %), Cystoisospora ohioensis (4.3 %), and Cystoisospora canis (3 %). For the first time for dogs in Albania, fecal examination indicated the occurrence of Hammondia/Neospora-like (0.2 %), Angiostrongylus lungworm (0.3 %), capillariid (2.8 %), and Linguatula (0.2 %) infections. Single and multiple infections with up to seven parasites concurrently were found in 152 (25.2 %, 95 % CI 21.8-28.9) and 93 dogs (15.4 %, 95 % CI 12.7-18.6), respectively. On univariate analysis, the dog's age, the dog's purpose (pet, hunting dog, working dog), the dog's habitat (city, suburban, rural), and environment (mainly indoors, indoors with regular outside walking, yard, kennel/run), presence/absence of other dogs and/or cats, history of anthelmintic use, and season of examination were identified as significant (p dogs to various types of endoparasitism while the variables breed (pure breed dogs vs. mixed-breed dogs), gender, and type of food were not significant predictors.

Aquaculture activities are well known to be the major contributor to the increasing level of organic waste and toxic compound in the aquaculture industry. Along with the development of intensive aquaculture in China, concerns are evoked about the possible effects of ever-increasing aquaculture waste both on productivity inside the aquaculture system and on the ambient aquatic ecosystem. Therefore, it is apparent that appropriate waste treatment processes are needed for sustaining aquaculture development. This review aims at identifying the current status of aquaculture and aquaculture waste production in China. China is the world's largest fishery nation in terms of total seafood production volume, a position it has maintained continuously since 1990. Freshwater aquaculture is a major part of the Chinese fishery industry. Marine aquaculture in China consists of both land-based and offshore aquaculture, with the latter mostly operated in shallow seas, mud flats and protected bays. The environmental impacts of aquaculture are also striking. Case studies on pollution hot spots caused by aquaculture have been introduced. The quality and quantity of waste from aquaculture depends mainly on culture system characteristics and the choice of species, but also on feed quality and management. Wastewater without treatment, if continuously discharged into the aquatic environment, could result in remarkable elevation of the total organic matter contents and cause considerable economy lost. Waste treatments can be mainly classified into three categories: physical, chemical and biological methods. The environmental impacts of different aquaculture species are not the same. New waste treatments are introduced as references for the potential development of the waste treatment system in China. The most appropriate waste treatment system for each site should be selected according to the sites' conditions and financial status as well as by weighing the advantages and disadvantages of

There is limited published information regarding antimicrobial use (AMU) and antimicrobial resistance (AMR) in aquaculture. Our objective was to determine the opinions of aquaculture-allied professionals around the world on the frequency of AMU and AMR in common aquatic species. The study questionnaire included five sections: respondent demographics, extent of AMU in aquaculture, frequency of observations of AMR in aquaculture, AMR monitoring and surveillance and antimicrobial susceptibility testing in various jurisdictions. It was administered in English and Spanish to 604 professionals in 25 countries and with varying expertise in aquaculture. The response rate was 33% (199/604). Over half of the participants had >10 years of experience in aquaculture: 70% (140/199) were involved in fish health/clinical work and their primary experience was with salmon, tilapia, trout, shrimp (including prawn) and/or catfish. Tetracycline use was reported by 28%, 46%, 18%, 37% and 9% of respondents working with catfish, salmon, tilapia, trout and shrimp, respectively. Resistance to tetracycline in one or more species of bacteria was reported as 'frequent-to-almost always' for the same aquaculture species by 39%, 28%, 17%, 52% and 36% of respondents, respectively. 'Frequent-to-almost always' use of quinolone was reported by 70% (32/46) and 67% (8/12) of respondents from the United States and Canada, respectively, where quinolone products are not approved for aquaculture, and extra-label fluoroquinolone use is either prohibited (United States) or discouraged (Canada). Similar frequencies of quinolone use were also reported by the majority of respondents from Europe [70% (7/10)] and Asia [90% (9/10)] where labelled indications exist. This baseline information can be used to prioritize research or surveillance for AMU and AMR in aquaculture. © 2012 Blackwell Verlag GmbH.

Contraceptive social marketing in Albania - the NESMARK story.

Paravani, Ardian; Orgocka, Aida

2013-06-01

To present the history of social marketing of modern contraceptives in Albania. We review documentation and activity of NESMARK, an Albanian non-governmental social marketing organisation, and national data on adoption of modern contraception. During 15 years of awareness raising, sales of affordable products, and provider training, NESMARK has impacted the introduction and adoption of modern contraception in Albania. NESMARK is the country's main distributor of emergency contraception (EC) and complements the public sector in the distribution of condoms and oral contraceptives. NESMARK has made major efforts to overcome prevalent taboos and misinformation held by medical and nursing personnel, pharmacists and the general public, regarding the effectiveness and safety of condoms, oral contraceptives, and EC. NESMARK has contributed to increasing the choices for modern contraception methods in Albania by providing affordable contraceptives, training providers, and educating the general population. However, widespread use of withdrawal coupled with the belief that it is as or more effective than modern contraception, continues to limit uptake of new methods and is a significant challenge to comprehensive and sustained social marketing programmes.

Full Text Available Albania possesses a wide range of ecological systems including coastal zones, estuaries and lagoons, lakes and wetlands, grasslands, middle-low altitude coppice forests, high altitude forests, alpine vegetation and glacial areas. The country possesses about 3,250 species of vascular plants, 165 families and more than 900 genera. Medicinal plants (botanicals and non-timber forest products have a long history of importance in the culture and traditional knowledge of Albania. Proper legislation and especially legal and regulatory framework enforcement for the regulation of this developing industry remains lacking. A Strategy of Biodiversity plan developed in 2000 calls for an increase in the Protected Areas system which currently covers some 6 % of Albania's area to a total area of 435,600 ha, approximately 15 % of the country's territory. Changes in the legal and policy framework as well as institutional structures is required to move forward and provide an environment for biodiversity conservation and a sustainable protected areas system. The various threats to biodiversity and constraints to improvement are outlined as well as recommendations for sustainable use, assessment and regulation.

Full Text Available Tourism is one of the main pillars of economy for many countries in the world. It influences the economy and offers more employment possibilities every year. Mediterranean countries have a favorable, geographical position and climate to develop tourism. Most of these countries, have obtained higher incomes from this industry, and as a result, more prosperity and economic development. Today, about 30 % of the world’s tourists spend their vacations in the Mediterranean Region. Albania is one of these countries and it has great possibilities for the future.The nature of Albania, it’s geographical position and its panorama, the climatic and physical diversity of its territory, represent some of its rich resources and strengthness. Previously, Albania’s economy depended in agriculture and small industries. After the 90-s, when many citizens left the country, the situation changed and even that source of income became inconsiderable. Heavy or textile industry, were hardly developed. Tourism was hardly developed too. Only few investments were made in this sector. In October 2012, EU Commission recommended Albania to be granted the EU candidate status. Therefore, Albania’s economy has to be developed according to EU standards. In this paper we would like to assess, which may be some important and effective innovative management strategies for Albania’s tourism. What are some of the steps to follow in this direction? The article aims to make a comparison with Greece and Montenegro, as reference points, in order to understand these countries’ touristic strategies and try to adapt some of them or think about new effective ones. It aims to provide a profile that shows; strengths, weaknesses, opportunities and threats. The study will be based in official statistics and scientific literature. The study concludes that the economic benefits of tourism are considerable, immediate and there are many new ways to activate the natural sources of Albania.

Serbia’s attitude towards Albania during the period of Wilhelm Wied

Directory of Open Access Journals (Sweden)

Milazim Elshani

2016-07-01

Full Text Available This manuscript analyzes a distinctive period of Albanian history, that after the Balkan Wars and Conference of Ambassadors in London, a period of external political influences with many different interests to implement or prevent the development of the newly created Albanian state. In this context the article focuses in the attitude of Serbia towards Albania, with Serbia’s aim to disable the consolidation of the Albanian state. It tried to influence in the political circumstances regarding the nomination of the ruler prince or at least it tried to alter the situation in the field through its different exponents, religious or political affiliations, in order to make the longstanding dream possible to cruise through the Albanian lands. The declaration of Albanian Independence evoked great concern to the Balkans neighboring states who had dedicated Albania as war trophy. On the other hand, the Serbian politics tried to find elements which would undermine the act of Independence or to put it on a shade in any form. The interest of Serbian politics towards Albania was consistent. If we want to best understand the attitude of the Serbian politics towards Albanians, during this time, we have to analyze in a comparative manner Serbia’s politics in Albania and Kosovo and other occupied territories. While in Albania it committed itself for a Muslim prince, in the occupied Albanian territories it followed a strict anti-Islamic and anti-Albanian policy.

Full Text Available Unemployment is a big economical and social issue for each country, in particular for Albania, which is a country that comes from a centralized system where the state ensured full employment. In the struggle of applying the transition to market economy, each government had to face the two-digit levels of unemployment. Because of this, the application of the right policies in order to decrease the level of unemployment has been in the centre of the program of each government in Albania. The objective of this paper is to show if the undervaluation or overvaluation of the real exchange rate can affect in a significant way the level of employment in Albania and that to answer the question, if the real exchange rate can be used as a political instrument for the reduction of the level of unemployment. There are relatively few works that study the impact of real exchange rate on the Albanian economy and in my knowledge there is not a previous work on employment and real exchange rate relationship in Albania, so this can be considered as the first study that attempt to assess this relationship. To evaluate the link between the real exchange rate and the level of employment the Johansen procedure and Vector Error Correction Term method is used. The result of the study demonstrates not statistically significant impact of real exchange rate on level of employment, suggesting that the increase of competition of the country through the real exchange rate doesn’t improve the condition of the employment in Albania, so the Albanian government should implement other strategies to increase the level of employment in the country.

Free to Learn: The Rationale for Legalizing Homeschooling in Albania

Directory of Open Access Journals (Sweden)

Timothy Paul Hagen

2011-12-01

Full Text Available In the years following the collapse of communism in 1991, Albania allowed greater freedom in educational choice by abolishing the government monopoly on education and allowing private schools to operate. However, it is only now, two decades after the fall of communism, that Albania is moving towards officially recognizing the most natural and fundamental option for educating its citizens – allowing parents to educate their children at home. By looking at homeschooling from the perspectives of student achievement, individual freedom, and natural rights, this paper will show that it is good and proper for Albania – and all countries worldwide – to legally recognize the natural right of parents to homeschool their children. While homeschooling is the best option for some children, it may not be the best for all children. Homeschooling should be one option alongside public schools, private schools, private tutoring, and distance-learning programs. While this article focuses on homeschooling in Albania, relying on research from North America, it contributes to the wider discussion of homeschooling policy in Europe, where policies range from homeschooling being largely illegal in nations such as Bulgaria and Germany to being freely permitted with minimal regulation in a nation such as the United Kingdom.

Full Text Available The main research question for this paper is: Are there radical left wing movements in Albania and Kosovo and what are their main traits? Through answering this question, we will explore the development (or lack thereof of radical left wing movements. With radical left we intend movements that reject the underlying socio-economic structure of contemporary capitalism and its values and practices without opposing democracy. Through a thorough desk research and several interviews with experts and activists both in Albania and Kosovo, we look at the two case Political Opportunity Structures to study the emergence, the strategies, success or failures of the radical left. In Albania the radical left has been in decline since 1992, with only a recent revival from 2009 on. In Kosovo, the Lëvizja Vetëvendojse! (Self-Determination Movement, a civil movement transformed in a party, has succeeded in imposing its left agenda. Both cases employ a new rhetoric unrelated to the past communist regimes thus changing the perspective of political debate in both countries.

Full Text Available Political transition of Albania is a phenomenon that started since the death of Enver Hoxha, the dictator of communist regime in Albania. After the death of Enver Hoxha on 11 April 1985, Ramiz Alia was appointed as his successor, who for 40 years had been at Enver Hoxha’s side as his most trusted man. He succeeded Hoxha for nearly 6 years believing that he would maintain the communist system. Ramiz Alia came on duty as the head of the Albanian state when the economic situation was very precarious. Political and economic legacy led by Hoxha was almost miserable. The country had the severest political system throughout the communist bloc. In a political point of view, the country’s new leader was elected precisely to continue the political legacy of former leader Hoxha. Ramiz Alia was forced to take immediate measures to change the degraded situation. He undertook several reforms to improve the situation in the country. Among other things, Alia expressed the equality of Albanian citizens, freedoms and human rights. Events were passing each other, marking a great historical importance. Among other things, Alia approved the political pluralism giving way to significant social changes. Echoes of these events and the positive developments in the country do not remain outside the attention of internationals. The arrival of political pluralism and the establishment of Democratic Party, the first opposition party in the country and other political entities exposed the European dream of Albanians. Massive movements in the form of protests and rallies, aimed at overturning the communist regime in the country Main objective of this paper is the analysis of the Political transition of Albania 1985-1991.

This paper attempts an overview of the progress made in the field of aquaculture. Aquaculture is a system of techniques strongly influenced by natural environmental conditions. Aquaculture as a biological technique oriented towards the production of useful aquatic organisms, is reaching a stage of consolidation which will place it on an equal footing which agriculture and animal husbandry. Aquaculture provides important economic and nutritional benefits to many regions of developing world. In 1994, over 90 percent of total aquaculture production was in Asia, with China, India, Japan, Indonesia, Thailand, Philippines and Republic of Korea as the seven leader producers. [Italiano] L`acquacoltura, vale a dire l`arte di riprodurre artificialmente pesci, alghe, molluschi e crostacei ed altri organismi acquatici utili all`uomo, si presenta oggi come un`attivita` di assoluto rilievo nell`insieme dei vari comparti di produzione alimentare. L`aumento della produzione e` costante anche se cinque paesi asiatici (Cina, India, Giappone, Filippine e Corea del Sud) contribuiscono per l`80% al volume della produzione mondiale. Nel presente lavoro vengono descritti lo stato dell`acquacoltura e della maricoltura nel mondo e le filiere di allevamento delle principali specie.

Full Text Available Social accounting is the process of communicating the social and environmental effects of organizations economic actions to particular interest groups within society and to society at large. This research paper is focused on the concepts of social and environmental accounting, viewed as an important part of the Albanian policy preparation for European Union integration. Presently, however, the EU notion of corporate engagement and Social accounting is still a new concept in the region. The paper aims to reveal the Albanian reality, as a country with strong aspiration toward EU. For this purpose we have analysed the main initiatives and projects implemented in the region and in Albania aimed at developing corporate social responsibility (CSR. This paper examines the applicable and relevant paragraphs of the global financial reporting standards (IFRS. The relevant paragraphs for environmental accounting have been analyzed in relation to the environmental financial reporting. We believe that this research may serve as a starting point for further studies on this topic. This paper concludes that social and environmental reporting practices are increasing day by day in the region. In Albania the awareness of CSR and how it can be applied is still quite low, perceived mainly as an opportunity to adopt international standards and engage in environmental protection. Hence we believe that improvements in quality of environmental financial reporting are required.

Full Text Available The banking system, as the most important component of the financial system in Albania, plays a crucial role in economic development. Measuring the efficiency of the intermediation system requires special attention because of its implications on the level of investments, savings, resource allocation etc. The most common indicator for the efficiency of the banking system is the cost of intermediation, measured by the spread of interest rates (the difference between the average lending rate and the average deposit rate. The study aims to analyze the trend of interest rate spread (IRS in Albania for the period 2005-2014 based on a comparative analysis with other countries and to identify the factors with significant impact on the level of IRS in the local currency. It is based on the empirical analysis of several macroeconomic and market factors that determine IRS, used in previous studies in this field, but also incorporating other elements that are associated with the characteristics of the Albanian system. Albania has experienced high IRS during the last decade, with large fluctuations, especially in the local currency. The results of the study based on quarterly panel data for the period 2005-2014 show that IRS in Albania is negatively affected by the level of development of the banking sector and the discount rate, while inflation, deficit rate and monetary supply put positive pressure on this indicator.

Full Text Available An important factor that has contributed in the realization of a positive economic growth in Albania in the last 20 years is undoubtedly the Small and Medium Enterprise (SME sector. SME financing is a topic of significant research interest to academics, and an issue of great importance to the policy makers around the world. Economic, as well as technical and social arguments warrant the promotion of SMEs. They create large scale, low-cost employment opportunities, use locally available inputs and technologies, mobilize small and scattered private savings, develop entrepreneurship, and correct the regional imbalance in development that exists in industrialized countries. Several studies identify financing, infrastructure facilities, taxes, regulations and stability in policies as major obstacles for the growth of small and medium businesses. Improving the business environment for SME development is a key objective of the policy framework in Albania.

Full Text Available The religious tolerance is one of the rarest values of the tradition of the Albanian people. It is widely accepted that Albanian people are well known about these values about an excellent coexistence among the believers of different religious communities that are in Albania mainly Muslims and Christians. In this study we bring the essentials of this phenomenon promotional roots of these values while viewed from a previously untreated point of view and in an attempt to answer the questions Where does it stem from the religious coexistence in Albania What are the main promoters of this phenomenon What has been the attitude of the religious clergy in Albania Have they been and are the imams and priests the promotion of tolerance and religious coexistence in Albania These are some of the questions answered in this modest study focusing on how nice and with how much delicacy the lectures of the Clergy have addressed this issue to the faithful or to the world in general. Since they enjoyed undisputable reputation and influence in the majority of the population in the most critical moments of national history the leaders of Muslims believers not only have promoted tolerance and religious coexistence but they have considered the believers of other faiths as brothers preaching this conviction in front of their Muslim believers. These preachings were firstly begun by VehbiDibra who was the first Chairman of the Muslims and all clerics without exception to this day. Also unforgettable are the sermons of priests like Fr. GjergjFishta Fr. ShtjefnGjeovi or Metropolitan VisarionXhuvani to conclude with pearls of Orthodox priest Fan S. Noli who amazed the world with his three speeches in front of world leaders the League of Nations being representative of all Albanians although Orthodox believers were only 20 of the population.

Albania is a Balkan country endemic for Crimean-Congo hemorrhagic fever (CCHF). It was shown previously that CCHF virus (CCHFV) sequences from Albanian patients cluster into Europe 1 clade. Aim of the present study was to test for CCHFV ticks collected in several regions of Albania, and to determine the genetic lineage(s) of the CCHFV strains in relation with their geographic distribution. A total of 726 ticks (366 Hyalomma marginatum, 349 Rhipicephalus bursa and 11 Rhipicephalus sanguineus) collected from livestock during 2007-2014 were included in the study. Thirty of 215 (13.9%) tick pools were positive for CCHFV. Lineage Europe 1 was detected in H. marginatum ticks collected in the endemic region of Albania, while lineage Europe 2 was detected mainly in R. bursa ticks in various regions of the country. Both genetic lineages were detected in the CCHF endemic area (northeastern Albania), while only Europe 2 lineage was detected in the south of the country. A higher genetic diversity was seen among Europe 2 than Europe 1 Albanian sequences (mean distance 3.7% versus 1%), suggesting a longer evolution of AP92-like strains (Europe 2) in their tick hosts. The present study shows that besides CCHFV lineage Europe 1, lineage Europe 2 is also present in Albania. Combined with results from recent studies, it is concluded that lineage Europe 2 is widely spread in the Balkans and Turkey, and is associated mainly with R. bursa ticks (at least in this region). Its pathogenicity and impact to the public health remain to be elucidated. Copyright © 2017 Elsevier B.V. All rights reserved.

2015-03-01

Full Text Available Albanian insect fauna is one of the least studied in Europe. In 2012 and 2013 surveys were undertaken with the aim of improving the knowledge of the distribution of butterflies, particularly in the southern part of the country. This research has resulted in the publication of three new species records for Albania. Here we add two new species to the list of native butterflies of Albania, Melitaea ornata Christoph, 1893 and Cupido alcetas (Hoffmannsegg, 1804. We recorded a total of 143 species including several confirmations of historical published records. The total number of species has consequently increased to 198, which is comparable with butterfly diversity in neighbouring countries. Unlike its neighbours, Albania has preserved many of its traditional agricultural practices and consequently its rich fauna has been well protected during the last decades. However, with the opening up of the country to outside influences this will undoubtedly change as the process of intensification has already started in more populated coastal areas. It is therefore imperative to identify important butterfly areas in need of conservation and to take decisive measures to preserve traditional agricultural practices.

Fifty samples from 14 local and 2 exotic olive cultivars were collected from 10 commercial orchards and one collection field and inspected for Arabis mosaic virus (ArMV, Cherry leaf roll virus (CLRV, Strawberry latent ringspot virus (SLRV, Olive latent virus 1 (OLV-1, Olive leaf yellowing-associated virus (OLYaV, Cucumber mosaic virus (CMV, Olive latent virus-2 (OLV-2 and Tobacco necrosis virus strain D (TNV-D by a one-step RT-PCR assay using virus-specifi c primers. None of these viruses were found in the source plants except SLRSV and OLYaV, which were detected in a ‘K. M. Berat’ olive tree grown in the collection field. These findings are important because the incidence of olive virus diseases is low in Albania but high in other Mediterranean countries. Thus, all efforts should be to directed to maintaining the Albanian olive germplasm pathogen-free and in the best agronomical and phytosanitary condition possible.

Outlook on principles for designing integrated and cascade use of low enthalpy geothermal energy in Albania

International Nuclear Information System (INIS)

Frasheri, Alfred

2000-01-01

In the countries of Western Europe, USA and Japan, the technologies of a new generation evolved to exploit high and low enthalpy geothermal sources and mineral waters. There are great experiences for modern complex exploitation of these resources, which increase natural wealth values, in European Community Countries. In Albania, rich in geothermal resources of low enthalpy and mineral waters, similar new technologies have been either partly developed or remain still untouched. Modern complex exploitation is very rare phenomena. Large numbers of geothermal energy of high and low enthalpy resources, a lot of mineral water sources and some CO 2 gas reservoirs represent the base for successfully application of modern technologies in Albania, to achieve economic effectively and success of complex exploitation. Actuality, there are many geothermal, hydrogeological, hydrochemical, biological and medical investigations and studies of thermal and mineral water resources carried out in Albania. Generally, these investigations and studies are separated each from the other. Their information and data will serve for studies and evaluations in Albania regional scale. These studies and evaluations are necessary to well know in regional plane the thermal and mineral water resources potential and geothermal market of the Albania. According to results of these new studies, the evaluation for the perspective level of the best areas in country will be necessary. After the evaluation is possible to start investments in these areas. These investments will be profitable in a short period of time. Integrated and cascade use of geothermal energy of low enthalpy it is important condition for profitable investment. In Albania, there are several geothermal energy sources that can be used. Such geothermal energy sources are natural thermal water springs and deep wells with a temperature of up to 65,5 o C. Deep abandoned oil wells can be used as 'Vertical Earth Heat Probe'.

China is the largest fishery producer worldwide in term of its aquaculture output, and plays leading and decisive roles in international aquaculture development. To improve aquaculture output further and promote aquaculture business development, infectious diseases and immunity of fishes and other aquaculture species must be studied. In this regard, aquaculture proteomics has been widely carried out in China to get a better understanding of aquaculture host immunity and microbial pathogenesis as well as host-pathogen interactions, and to identify novel disease targets and vaccine candidates for therapeutic interventions. These proteomics studies include development of novel methods, assays, and advanced concepts in order to characterize proteomics mechanisms of host innate immune defense and microbial pathogenesis. This review article summarizes some recently published technical approaches and their applications to aquaculture proteomics with an emphasis on the responses of aquaculture animals to bacteria, viruses, and other aqua-environmental stresses, and development of broadly cross-protective vaccine candidates. The reviewed articles are those that have been published in international peer reviewed journals. Copyright © 2012 Elsevier Ltd. All rights reserved.

Full Text Available Almost all countries face the problems of trade balance, although they are more inherent in developing countries and economies in transition. A majority of economists adheres to a common opinion real depreciation may lead to an improvement of the trade balance. That said, countries encountering trade balance issues use real exchange rate depreciation in order to improve the trade balance situation. Albania belongs to the group of transition countries that has been facing negative trade balance over last two decades. National currency devaluations of the lek (ALL have been used by Albania to improve its trade balance. Therefore, this paper intends to investigate the effect of the real effective exchange rate depreciation of the ALL on the trade balance of Albania using quarterly data from 1994 to 2015. Bounds testing cointegration approach, vector error correction model (VECM and impulse response were used for empirical analysis. The results of the study show that there exists a long-term cointegration between the real effective exchange rate depreciation and the trade balance. Specifically, real effective exchange rate depreciation positively affects the trade balance of Albania in both the long-run and short-run indicating the weak presence of the J-curve effect. Important recommendations were derived from the results.

Mariola KAPIDANI

2015-12-01

Full Text Available The principle of decentralization is a fundamental principle for the establishment and operation of local government. It refers to the process of redistributing the authority and responsibility for certain functions from central government to local government units. In many countries, particularly in developing countries, fiscal decentralization and local governance issues are addressed as highly important to the economic development. According to Stigler (1957, fiscal decentralization brings government closer to the people and a representative government works best when it is closer to the people. Albania is still undergoing the process of decentralization in all aspects: political, economic, fiscal and administrative. Decentralization process is essential to sustainable economic growth and efficient allocation of resources to meet the needs of citizens. Albania has a fragmented system of local government with a very large number of local government units that have neither sufficient fiscal or human capacity to provide public services at a reasonable level (World Bank. However, recent administrative and territorial reform is expected to have a significant impact in many issues related to local autonomy and revenue management. This paper is focused on the progress of fiscal decentralization process in Albania, stating key issues and ongoing challenges for an improved system. The purpose of this study is to analyze the effects of recent territorial reform, identifying problems and opportunities to be addressed in the future.

Full Text Available Labour Market Policy of the Republic of Albania in terms of design (preparation, case identification, formulation, and approval, programming and budgeting, implementation, monitoring and evaluation has a short experience (1995-ongoing. The influence and presence of hierarchy model is very high beside the support of different programs and projects through bilateral and EU programs. Still there are a lot of key issues to be addressed. The most important issues to be addressed in this paper are evidence based related to: • The Availability of Labor Market Information and its structure on national, regional and local level in Albania and how much this information is used for -policy making and –monitoring/evaluation in terms of input, output, outcome and impact. • Mode of the governance of the labor market in Albania and challenges to pass from the hierarchy to market and network governance. The main aim of this paper/article is to do a complete and deep analysis of the actual situation of labor market information system and labor market governance in Albania, and to propose conclusions and recommendations that will improve both labor market information system and the labor market governance from hierarchy to market and network governance, because good and standardized labor information system can help towards right policy decisions and good governance of LM policy means more employment, more stability, more social inclusion in the society.

Emergency contraception in Albania: a multimethods qualitative study of awareness, knowledge, attitudes and practices.

Contraceptive prevalence is relatively low in Albania, and abortion is the mainstay of family planning. Although levonorgestrel-only emergency contraceptive pills are available, uptake of this method is minimal. Emergency contraception (EC) could play a significant role in addressing women's need for an effective and discreet pregnancy prevention method. However, information about the dynamics surrounding EC is limited. In 2016-2017, we conducted a multimethods qualitative study that aimed to explore awareness, knowledge, attitudes and practices toward EC in Albania. This project comprised four components: a community-based survey with 115 respondents, six focus group discussions with women of reproductive age, 19 semistructured key informant interviews, and 16 structured interviews with retail pharmacists. We analyzed our data using descriptive statistics and for content and themes. Our findings suggest that EC is widely available in pharmacies in Albania. However, a quarter of our survey participants did not know whether EC was available, and more than a third did not think EC was safe to use. Women face numerous barriers to accessing this form of contraception. Misconceptions about hormonal contraceptives, in general, and about progestin-only EC in particular, lack of training among providers, and stigma and fear of judgment were common obstacles identified by participants. Misinformation and lack of knowledge about EC among women and providers in Albania appears common. Training health service providers, raising awareness among women, and developing linguistically and culturally resonant materials for distribution could be keys to improving access to and use of EC. Although the availability of progestin-only EC is widespread in Albania, our findings suggest that more work needs to be done to align national regulatory policies with international standards, facilitate evidence-based service delivery, and increase access to medically accurate information in

Epigenetic considerations in aquaculture

Mackenzie R. Gavery

2017-12-01

Full Text Available Epigenetics has attracted considerable attention with respect to its potential value in many areas of agricultural production, particularly under conditions where the environment can be manipulated or natural variation exists. Here we introduce key concepts and definitions of epigenetic mechanisms, including DNA methylation, histone modifications and non-coding RNA, review the current understanding of epigenetics in both fish and shellfish, and propose key areas of aquaculture where epigenetics could be applied. The first key area is environmental manipulation, where the intention is to induce an ‘epigenetic memory’ either within or between generations to produce a desired phenotype. The second key area is epigenetic selection, which, alone or combined with genetic selection, may increase the reliability of producing animals with desired phenotypes. Based on aspects of life history and husbandry practices in aquaculture species, the application of epigenetic knowledge could significantly affect the productivity and sustainability of aquaculture practices. Conversely, clarifying the role of epigenetic mechanisms in aquaculture species may upend traditional assumptions about selection practices. Ultimately, there are still many unanswered questions regarding how epigenetic mechanisms might be leveraged in aquaculture.

World Aquaculture: Environmental Impacts and Troubleshooting Alternatives

Martinez-Porchas, Marcel; Martinez-Cordova, Luis R.

2012-01-01

Aquaculture has been considered as an option to cope with the world food demand. However, criticisms have arisen around aquaculture, most of them related to the destruction of ecosystems such as mangrove forest to construct aquaculture farms, as well as the environmental impacts of the effluents on the receiving ecosystems. The inherent benefits of aquaculture such as massive food production and economical profits have led the scientific community to seek for diverse strategies to minimize the negative impacts, rather than just prohibiting the activity. Aquaculture is a possible panacea, but at present is also responsible for diverse problems related with the environmental health; however the new strategies proposed during the last decade have proven that it is possible to achieve a sustainable aquaculture, but such strategies should be supported and proclaimed by the different federal environmental agencies from all countries. Additionally there is an urgent need to improve legislation and regulation for aquaculture. Only under such scenario, aquaculture will be a sustainable practice. PMID:22649291

”Fear of Floating” in Albania and Economic Growth

Directory of Open Access Journals (Sweden)

Besart Kadia

2015-06-01

Full Text Available This study endeavours to understand the volatility of the exchange rate in Albania and to see if there are sign of “fear of floating” present. De jure Albania currently applies a flexible exchange rate regime. Traditionally the main argument in favour of this policy is that monetary policy is not constrained by the predetermined level of the exchange rate. Thus, monetary policy sets interest rates in order to achieve domestic equilibrium (ie. price stability while the nominal exchange rate adjusts to balance the external accounts. Theoretical evidence concerning the impact of exchange rate stability on growth is mixed. The theoretical arguments in favour of flexible exchange rates are mainly of macroeconomic nature, as flexible exchange rates allow for an easier adjustment in response to asymmetric country specific real shocks. From a microeconomic perspective low exchange rate volatility can be associated with lower transaction costs for international trade and capital flows thereby contributing to higher growth.

Antimicrobial resistance (AR) detected by disc diffusion and antimicrobial resistance genes detected by DNA hybridization and polymerase chain reaction with amplicon sequencing were studied in 124 marine bacterial isolates from a Chilean salmon aquaculture site and 76 from a site without aquaculture 8 km distant. Resistance to one or more antimicrobials was present in 81% of the isolates regardless of site. Resistance to tetracycline was most commonly encoded by tetA and tetG; to trimethoprim, by dfrA1, dfrA5 and dfrA12; to sulfamethizole, by sul1 and sul2; to amoxicillin, by blaTEM ; and to streptomycin, by strA-strB. Integron integrase intl1 was detected in 14 sul1-positive isolates, associated with aad9 gene cassettes in two from the aquaculture site. intl2 Integrase was only detected in three dfrA1-positive isolates from the aquaculture site and was not associated with gene cassettes in any. Of nine isolates tested for conjugation, two from the aquaculture site transferred AR determinants to Escherichia coli. High levels of AR in marine sediments from aquaculture and non-aquaculture sites suggest that dispersion of the large amounts of antimicrobials used in Chilean salmon aquaculture has created selective pressure in areas of the marine environment far removed from the initial site of use of these agents. © 2014 Society for Applied Microbiology and John Wiley & Sons Ltd.

Shaping the Victim: Borders, security, and human trafficking in Albania

Directory of Open Access Journals (Sweden)

James Campbell

2013-09-01

Full Text Available Borders are productive sites where knowledge is gathered and migrant populations are formed. The knowledge gathered from victims of trafficking reinforces a victim narrative that represents a perceived threat to society by highlighting violence, criminality, coercion, and naivety. Using Albania as a case in point, the article looks at trafficked people and the narratives of victimhood that surround them. In the case of trafficked people, the border projected out towards other states produces a discursively defined victim of trafficking. When projected back within the national territory, the border essentially produces a criminalised sex worker. To argue this point, the article discusses the role victims of trafficking play in the EU and looks at how international norms espoused by the OSCE and IOM have prepped the Albanian border for EU ascension and created the means for governable populations within Albania.

Full Text Available On 06.24.2014 Albania was granted the status of candidate country. The foreign ministers of the 28 European Union member states decided unanimously to grant the candidate status for Albania. After receiving the status of “candidate country” for EU membership, the institutional relations with European international bodies are becoming stronger. One of these institutions, which during this time has increased its authority with Albania, is the European Parliament. In this paper will be analyzed the composition, competences and functioning of this particular institution, which is not only important for the future of the European Union and its Member States, but also for those who aim to join in. The study will be based on decisions made by this legislative body, as the only direct representative of the citizens of the European Union, and the impact they have on the performance and functioning of the Member States and the EU itself. In order to verify the validity of these claims, the analysis aims to assess the scope of the legislative function of the European Parliament post-Lisbon, examining its participation in the EU lawmaking both from the point of view of quantity and quality in over the past legislatures. Particular attention has been given to the examination of the changes that have taken place with the entry into force of the Lisbon Treaty, and the areas most affected. We will finally look at the work and contribution of the European Parliament, through the instruments at his disposal, on behalf of Albania’s progress towards full accession in the European Union.

The right to appeal under the constitution of Albania and court jurisdiction

Directory of Open Access Journals (Sweden)

Donika Plakolli

2017-03-01

Full Text Available The right to appeal is both a fundamental human right and a procedural tool, whereby parties exercise examination of the lawfulness of court rulings, etc. The constitution of the Republic of Albania, 1 approved in 1998, expressly provides for and guarantees the right to file an appeal. Unlike other rights, this fundamental right was not restricted, being in accordance with Article 17 of the Constitution, except for cases otherwise provided in the Constitution. In accordance with this constitutional right and guarantee, all codes of administrative procedures, civil and criminal procedure, provided for and widely guaranteed the exercise of the right to file an appeal. This absence of restriction of the right to fi le an appeal brought about an overload of court cases and trial delays, thus making the completion of the adjudication within a reasonable deadline uncertain. As a result, there rose the necessity to limit this right in the Constitution of the Republic of Albania. The amendments to the Constitution by Law no. 76/2016 also limited the right to fi le an appeal under Article 17 of the Constitution. However, these amendments were not complete, as they did not entail the exercise of the right to file an appeal against decisions of administrative authorities. The jurisdiction of the Constitutional Court of Albania is a guarantee of the right to appeal/effective access in the civil and administrative process, although slightly controversial in the criminal process. However, positive developments regarding the guarantee of effective access to the court have recently occurred. Even in the broad jurisdiction of the European Court of Human Rights, when cases from Albania have been adjudicated, violations of the right to effective appeal have been observed in the criminal process.

Patriarchy and fertility in Albania

Directory of Open Access Journals (Sweden)

Mathias Lerch

2013-07-01

Full Text Available BACKGROUND Theories of fertility collapse in the post-socialist era imply a decline in the moral primacy of traditional social institutions. Yet gender inequality actually increased in many countries, and there is a scarcity of empirical evidence for the role played by traditional social institutions in reproductive decision-making. OBJECTIVE We investigate whether patriarchal institutions sustained the fertility levels in Albania. The geography of marriage and family enlargement is related to the importance of patriarchy in kinship organisation and in the public sphere. To account for this spatial relationship we test the evidence for different pathways in patriarchal influence on reproductive decision-making including social effects, socialisation in patriarchal ideals, and the promotion of male fertility. METHODS We reconstruct reproductive histories from the 2001 Census and use data on attitudes and fertility intentions from the Reproductive and Health Survey 2002. Multilevel logistic regressions on marriage and (the intention of higher order births are used. RESULTS A majority of women endorsed patriarchal ideals and fertility transition was less advanced in more patriarchal municipalities. Patriarchal kinship organisation promoted early marriages and high fertility, which is shown to be achieved by social learning among peers and intergenerational social influences respectively, as well as by women's socialisation and a stopping behaviour in childbearing dominated by son-preference. Although gender inequality in the public sphere has also sustained the level of fertility and decreased the risk of marriage, it was not accounted for by these pathways of patriarchal influence. CONCLUSIONS Despite Albania's gradual opening to the world in a period of economic and political crisis, traditional social institutions remain important for family behaviours.

Integrated geophysical surveys for searching of podiform chromite in Albania

The purpose of this paper is to describe the application of geophysical methods to the search for chromite in Albania. Albania is well known for its chromite resources and ranks third amongst world producers of high-quality chromite. The ultramafic massif of Bulqiza, is the most important chromite bearing one. Surveying a surface of about 120 square kilometers (30% of massifs area) in that massif with integrated geophysical methods a considerable number of targets has been discovered, from which some are already objects under mine activity. In the integrated methods for chromite exploration in Bulqiza ultramafic massif are included: geological, gravity, magnetic and electrical mapping of the scale 1:2000 with survey grids 40x20m, 20x5m. Based on the interpretations of geophysical exploration were projected drilling which led to the discovery of some big ore deposits. (author). 12 refs., 3 figs

Potential drivers of virulence evolution in aquaculture

2016-01-01

Infectious diseases are economically detrimental to aquaculture, and with continued expansion and intensification of aquaculture, the importance of managing infectious diseases will likely increase in the future. Here, we use evolution of virulence theory, along with examples, to identify aquaculture practices that might lead to the evolution of increased pathogen virulence. We identify eight practices common in aquaculture that theory predicts may favor evolution toward higher pathogen virulence. Four are related to intensive aquaculture operations, and four others are related specifically to infectious disease control. Our intention is to make aquaculture managers aware of these risks, such that with increased vigilance, they might be able to detect and prevent the emergence and spread of increasingly troublesome pathogen strains in the future.

2017-07-01

Recently, it was observed that there is an increasing application of nanoparticles (NPs) in aquaculture. Manufacturers are trying to use nano-based tools to remove the barriers about waterborne food, growth, reproduction, and culturing of species, their health, and water treatment in order to increase aquaculture production rates, being the safe-by-design approach still unapplied. We reviewed the applications of NPs in aquaculture evidencing that the way NPs are applied can be very different: some are direclty added to feed, other to water media or in aquaculture facilities. Traditional toxicity data cannot be easily used to infer on aquaculture mainly considering short-term exposure scenarios, underestimating the potential exposure of aquacultured species. The main outputs are (i) biological models are not recurrent, and in the case, testing protocols are frequently different; (ii) most data derived from toxicity studies are not specifically designed on aquaculture needs, thus contact time, exposure concentrations, and other ancillary conditions do not meet the required standard for aquaculture; (iii) short-term exposure periods are investigated mainly on species of indirect aquaculture interest, while shrimp and fish as final consumers in aquaculture plants are underinvestigated (scarce or unknown data on trophic chain transfer of NPs): little information is available about the amount of NPs accumulated within marketed organisms; (iv) how NPs present in the packaging of aquacultured products can affect their quality remained substantially unexplored. NPs in aquaculture are a challenging topic that must be developed in the near future to assure human health and environmental safety. Graphical abstract ᅟ.

Sanitary survey of the drinking water supply of Kombinati suburb-Tirana, Albania.

Angjeli, V; Reme, B; Leno, L; Bukli, R; Bushati, G

2000-01-01

Microbiological pollution of drinking water is a major health problem in the suburbs of the Albanian capital. Intermittent supply and contamination, resulting in several gastrointestinal manifestations, are the main concerns for the population and health workers. The risk of outbreaks of water-borne diseases is high. Pollution originates from contamination of drinking water with domestic sewage. This research investigated the drinking water cycle from its natural source to the consumer, analysing samples and verifying pollution levels in the microbiological and chemical setting. The most important pollution sources were found in the distribution network, due to cross-contamination with sewers and illegal connections. The second pollution source was found around the extraction wells. This is related to abusive constructions within the sanitary zone around the wells and maybe the highly sewage-contaminated river water which feeds the aquifer.

Full Text Available Aquaculture is gaining commendable importance to meet the required protein source for ever increasing human population. The aquaculture industry is currently facing problems on developing economically viable production systems by reducing the impact on environment. Sustainable and enhanced fish production from aquaculture may be better achieved through application of recent biotechnological innovations. Utilisation of transgenic technology has led to production of fishes with faster growth rate with disease resistance. The full advantage of this technology could not be achieved due to concern of acceptance for Genetically Modified Organisms (GMOs. The biotechnological intervention in developing plant based feed ingredient in place of fish meal which contain high phosphorus is of prime area of attention for fish feed industry. The replacement of fish meal will also reduce fish feed cost to a greater extent. Year round fish seed production of carps through various biotechnological interventions is also need of the hour. This paper discusses technical, environmental and managerial considerations regarding the use of these biotechnological tools in aquaculture along with the advantages of research application and its commercialization.

Full Text Available Electronic commerce has become a key aspect for many businesses all around the world. This new form of commerce has reshaped the ways of trading, revolutionizing the way of doing business and has brought competitive advantages for both consumer and business. Over the last few years Albania is witnessing a digital revolution too, however although internet access has grown significantly only a few enterprises and a small number of companies have engaged in e-commerce activities. The development of e-commerce is an important element of national economy. Being a new important sector, e-commerce can only flourish where there is a good infrastructure, both legal and technological, which is attractive to consumers and business. So the need for rules and principles facilitating e-commerce has become increasingly evident, too. This paper attempts to provide an overview of the regulatory framework, legal issues and the challenges in the development of electronic commerce in Albania.

Exploring the effects of energy consumption on output per worker: A study of Albania, Bulgaria, Hungary and Romania

International Nuclear Information System (INIS)

Kumar, Ronald Ravinesh; Stauvermann, Peter Josef; Patel, Arvind; Kumar, Radika Devi

2014-01-01

In this article, we explore the long-run cointegration between output, capital and energy consumption, in per worker terms, for Albania, Bulgaria, Hungary and Romania. We use the augmented Solow (1956) model and the ARDL bounds procedure (Pesaran et al., 2001) to examine the short-run and long-run effects of energy and capital on output (in per worker terms). We also conduct causality test using the Toda and Yamamoto (1995) non-causality procedure. Our results show the existence of long-run cointegration between output per worker and energy per worker for all the four countries. We find that energy per worker have a dynamic short-run positive effect in Albania (0.37%), Bulgaria (0.25%), Hungary (0.36%) and Romania (0.68%), and a long-run positive effect in Bulgaria (0.32%) and Romania (0.63%) which duly indicate that energy consumption has a momentous long-run effect in these two countries. The causality results indicate a unidirectional causation from output per worker to energy per worker for all the four countries, and from capital per worker to energy per worker for Albania and Romania. Consequently, a balance between effective energy consumption and sound energy conservation policies are likely to support economic growth in the four countries. - Highlights: • Energy has a short-run positive effect in Albania, Bulgaria, Hungary and Romania. • A long-run positive elasticity is noted in Bulgaria and Romania. • Output per worker cause energy per worker in the four countries. • A unidirectional causality from capital to energy is noted for Albania and Romania

Geoculture world system, access to Balkan and Albania

Ilirjan Çukaj

2015-03-01

Full Text Available If culture as a term covers a broad range of relations and social behavior, mutually implicated in influential and economic cycles of the global system, then it becomes wordy geoculture. Geoculture system is used as a term by Wallerstein (2004 who had treated it as a concept largely unused and under a theory of geoculture which plays an important role in the present world system. The theses that is presented in this article is that the global trajectory in the Balkan region is increasing from culture and that, it is imperative to establish a strategic culture direction and management, which, in turn, should be formed not only as a principal need, but also as an obligation of social state institutions to find the viable solutions of the global market policy, economy and culture. And in response to the challenging question the culture of integration becomes imperative now facing nationalism. Albania will have to manage perceptions, fears and realities arising from the above mentioned phenomenon, to establish a balance between the “inside” and “outside” views. In this sense main challenge of Albania is the management of cultural globalization to get the most of opportunities despite the risk of losing ground globally

Fish is one of the major sources of animal protein. Due to rising world populations, increasing income and urbanization, demand for fish has been increasing. In order to meet the need for more fish, aquaculture has become increasingly important as wild populations and production from capture fisheries have declined due to overfishing and poor management. In recent years, production from aquaculture has increased rapidly to address the shortfalls in capture fisheries, especially in Asia where aquaculture production accounts for about 90% of world aquaculture production by volume. This paper reviews the status of the world’s fish production, provides an update on Asian aquaculture, and highlights developments that are contributing to sustainable fish production, particularly integrated multi-trophic aquaculture and aquaponics.

Albania is a Balkan country in South-Eastern Europe which, in recent years, has undergone complex demographic, political and economical changes. A notable drop in infant and maternal mortality rates and a significant rise in economic indicators have been observed in recent years. Despite this, over 15% of the population living in the northern and north-eastern areas of the country lives in extreme poverty conditions. In recent years various healthcare system reforms have been introduced, including the introduction of private healthcare and improvement of the main hospital infrastructures but not much has been done to increase the provision of essential healthcare services especially in rural and poor areas. Inequalities in health care are therefore widespread and these particularly affect children living in critical areas. In this paper we describe a paediatric healthcare intervention programme conducted in Albania from 2002 to 2004, aimed at improving the health and nutrition status of children and tackling healthcare system inequalities. The intervention consisted in offering free healthcare services and assistance, delivered through the Albanian healthcare system, to 5280 children. It also involved a health education programme for the mothers. The impact of the programme on the prevalence of infant malnutrition was evaluated by examining the medical records of 1745 infants followed for at least 6 months. Prevalence of malnutrition significantly decreased, from 13.4% to 4.2% during the study period. Mortality in children aged 0-5 years also showed a considerable drop. These results confirm that an efficient and sustainable model of paediatric healthcare assistance in Albania is possible.

The Determinants of Actual Migration and the Role of Wages and Unemployment in Albania: an Empirical Analysis

Directory of Open Access Journals (Sweden)

Cristina Cattaneo

2008-06-01

Full Text Available The paper explores the determinants of internal migration in Albania, adopting the Harris-Todaro approach to migration: an internal migration function is estimated using district wage and unemployment rate differentials. The aggregate level wages and unemployment, included in the migration equation, are retrieved from a first stage wage and unemployment equations, estimated controlling for personal characteristics. Moreover, in order to test the predictions of the human capital model of migration, the difference between migrants and non-migrants is emphasized in the estimation. The data source is the "Living Standard Measurement Survey for Albania" (2002, undertaken by the national Institute of Statistics and the World Bank jointly. The results reveal that both wage and unemployment differentials are important determinants of the propensity to migrate in Albania. This conclusion is further emphasized by noting that migrants gain substantially in terms of higher returns to individual characteristics after emigration.

Full Text Available Competition law and cartel is the basis of a modern economy. While in the US, competition law exists and is terminologically known and is part of legislation since 1890 (Sherman Law, in Europe, it has become part of the founding treaties of the EU since 1957 by the Treaty of Rome. However, at that time, “culture of competition” would be born in the member states of the EU, which traditionally favour cartel agreements, state aid and the promotion of national products. Some EU member states have included competition law in their national legislation in the early 90-s. Rules were set for the first time on competition in the coal and steel market under Articles 65 and 66 of the Treaty of Rome, constituted a new terminology for member states. Albania has worked during these 24 years of democracy, to apply the basic principles of market economy and along with it the Lisbon Treaty, Regulations and EU Directives in the frame of competition. Main purpose of this manuscript is to give an overview of the abuse of dominant position in the frame of the most important court decision of this legal institution in Albania.

Full Text Available Aquaculture contribute ever more to the production of aquatic food worldwide, even if the sustainable limits for majority of wild fish stocks, are now almost reached or even exceeded. In the EU, aquaculture is an important economic activity in many coastal and continental regions. Aquaculture plays an important role in terms of access to food resources and it is necessary to use its potential to contribute to sustainable development, food security, economic growth and employment. In this regard, starting from EU aquaculture objectives, the paper intend to make an analysis of the national situation of aquaculture and its current potential. The paper presented the progress of Romanian investments in aquaculture, identifying needs and opportunities for the Romanian aquaculture development. Taking into consideration the natural resources available and the growth of global request of organic product, the development of ecologic aquaculture might represent o niche market for local producers.

Change of irradiative properties of the atmosphere during clear days is an indicator, among others, of existence of atmospheric aerosols and can be used as an indicator for assessment both air pollution and local modifications of solar energy potentials. The main objective of this study is estimation of influence of anthropogenic aerosols on solar energy falling in a horizontal surface during a cloudless day. We have analyzed and quantified the effect of aerosols on reducing the amount of solar energy that falls on the horizontal ground surface in cloudless sky conditions, estimating temporal evolution, both in daily and hour scale, considering also, side effects caused by relative humidity of the air wind speed and geometric factor. As an indicator of concentration of aerosols in atmosphere, we agreed to use the attenuation of solar radiation after the last rainy day. All data were corrected by factors such as, variations of relative humidity, wind speed and daily change of incident angle of solar radiation. We studied the change of solar insolation in three sites with different traffic intensity, one in city of Shkodra and two in city of Tirana. Fifteen days after last rainy day, approximate time needed to achieve saturation, the insolation drops only 3.1% in the city of Shkodra, while in two sites in city of Tirana are 8.5 % and 18.4%. These data show that reduction of solar insolation is closely related with anthropogenic activity, mainly traffic around the site of the meteorological station. The day to day difference tends to decrease with increasing of number of days passed from the last rainy day, which is an evidence of a trend toward a dynamic equilibrium between decantation process of aerosols during the night and their generation during the day.

To present the study design and baseline results of the longitudinal International Mobility in Aging Study (IMIAS) on gender differences in physical performance and mobility disability prevalence in five diverse societies. Data are from surveys on random samples of people aged 65-74 years at Canadian (Kingston, Ontario; Saint-Hyacinthe, Quebec), Mediterranean (Tirana, Albania) and Latin American sites (Natal, Brazil; Manizales, Colombia) (N=1995). Mobility disability was defined as reporting difficulty in walking 400m or climbing stairs. Activities of daily living (ADL) disability was based on any self-reported difficulty in five mobility-related ADLs. The short physical performance battery (SPPB) was used to assess physical performance. Poisson regression models were fitted to estimate prevalence ratios. Age-adjusted prevalence of low SPPB, mobility disability and ADL disability were higher in women than in men in all sites except for Kingston. After adjustment for education and income, gender differences in SPPB and ADL disability attenuated or disappeared in Saint-Hyacinthe and Manizales but remained large in Tirana and Natal and mobility disability remained more frequent in women than in men at all sites except Kingston. After further adjustment by chronic conditions and depressive symptoms, gender differences in mobility remained large at all sites except Kingston but only in Tirana did women have significantly poorer physical performance than men. Results provide evidence for gender as a risk factor to explain poorer physical function in women and suggest that moving toward gender equality could attenuate the gender gap in physical function in old age.

Vertical slip rates of active faults of southern Albania inferred from river terraces

Directory of Open Access Journals (Sweden)

Oswaldo Guzmán

2014-02-01

Full Text Available Fluvial terraces of Shkumbin, Devoll, Osum and Vjosa rivers (southern Albania and northwestern Greece are studied in order to quantify the vertical slip rates of the large active faults of the Dinaric-Albanic-Hellenic Alpine fold belt. The spatial and temporal variations of the incision rates along these rivers were estimated from the geomorphological mapping of the Quaternary sediments, the geometry and the dating of the terraces. Eleven terraces levels were identified in Albania from 68 geochronological ages already published or acquired for this work. The five lower terraces of the four studied rivers are well dated (10 new and 23 already published ages. These terraces are younger than 30 ka and their remnants are numerous. Their restoration allows estimating the regional trend of incision rate and the identification of local shifts. We argue that these shifts are linked to the active tectonics when they coincide with the faults already mapped by previous authors. Vertical slip rates for eight active faults in southern Albania are thus estimated for the last 19 ka and vary from ~0.1 to ~2 mm/a. The Lushnje Tepelene Thrust, that extends more than 120 kilometers, has a throw rate that varies from 0.2 to 0.8 mm/a, whereas the active faults of the extensional domain are segmented but are very active, with throw rates reaching locally 2 mm/a.

Comparisons of stakeholders’ perception towards the sustainable tourism development and its impacts in Shkodra Region (Albania

Directory of Open Access Journals (Sweden)

Drita Kruja

2010-01-01

Full Text Available Tourism is one of the world’s fastest growing industries, and has been identified as a means of generating national income in less industrialized economies. Like other countries, Albania has promoted tourism as a major source of national income. The tourism industry in Albania currently focuses on coastal areas, rather than on the unique features that set this country apart from its neighbors. Albania’s natural features have the potential to attract tourists seeking ecological and cultural experiences. Thoughtful, sustainable development of these resources could enhance community livelihoods throughout Albania. The purpose of this study was to discover if differences in perceptions of sustainable tourism development and principles in Shkodra Region existed between four stakeholder groups: residents, entrepreneurs, government officials, and tourists. Data were collected from stakeholders using a self competed questionnaire, which included Likert-style questions inquiring about attitudes and perceptions of sustainable tourism development in the community. The data gathered illustrate that the perception of sustainable tourism principles varies considerably among stakeholder groups. As a distinct stakeholder group, the majority of local residents generally were welcoming of tourism.

Does Aquaculture Support the Needs of Nutritionally Vulnerable Nations?

Directory of Open Access Journals (Sweden)

Christopher D. Golden

2017-05-01

Full Text Available Aquaculture now supplies half of the fish consumed directly by humans. We evaluate whether aquaculture, given current patterns of production and distribution, supports the needs of poor and food-insecure populations throughout the world. We begin by identifying 41 seafood-reliant nutritionally vulnerable nations (NVNs, and ask whether aquaculture meets human nutritional demand directly via domestic production or trade, or indirectly via purchase of nutritionally rich dietary substitutes. We find that a limited number of NVNs have domestically farmed seafood, and of those, only specific aquaculture approaches (e.g., freshwater in some locations have the potential to benefit nutritionally vulnerable populations. While assessment of aquaculture's direct contribution via trade is constrained by data limitations, we find that it is unlikely to contribute substantially to human nutrition in vulnerable groups, as most exported aquaculture consists of high-value species for international markets. We also determine that subpopulations who benefit from aquaculture profits are likely not the same subpopulations who are nutritionally vulnerable, and more research is needed to understand the impacts of aquaculture income gains. Finally, we discuss the relationship of aquaculture to existing trends in capture fisheries in NVNs, and suggest strategies to create lasting solutions to nutritional security, without exacerbating existing challenges in access to food and land resources.

Demiraj, Eglantina; Mucaj, Liri; Bicja, Mirela

2004-01-01

The climate change scenarios for Albania are prepared by using MAGICC/SCENGEN software, by CRU/UEA. MAGICC is run to calculate the global changes by using the mid- range IS92a emission scenario as the reference scenario and SRESA1, SRESA2, SRESB1 and SRESB2 as policy scenarios. SCENGEN is run using 6 of the available standardized GCM global warming patterns (HadCM2, UKTR, ECHAM4, CSIRO-TR, UIUC-EQ, GFDLLO). A composite pattern is constructed by using these 6 GSM altogether for each scenario. The climate change scenario for Albania leads to an annual increase in temperature up to 3.6 o C and decrease in precipitation to -12.5% by 2100 related to 1990. Severe summers with high temperatures (up to 4.10 o C) and low precipitation (up to -27%) are expected to meet over the territory that may cause negative or positive impacts. Autumn seems to play the second role in annual changes. Milder winters and warmer springs are expected as well. A decrease in the long term mean annual and seasonal runoff has to be expected for the whole territory and for three time horizons (years 2025, 2050, 2100). It would affect the surface water flow, reducing its amount. Under reduced surface flow and increased evaporation, the storage of reservoirs will decrease, which will effect the energy production by hydropower stations. Because of the reduction of stream flows in the wetlands, western part of Albania would experience both increasing demands for water and reduced supply of water, which would decrease wetland area. Other consequences of expected warming include not only changes in total water amount and levels, but also erosion of riverbeds, and modification of turbidity and sediment load. (Author)

Does financial aid help or harm developing countries: Case of Albania

Directory of Open Access Journals (Sweden)

Eglantina Hysa

2014-11-01

Full Text Available Development aid is a financial aid given by governments, NGOs, global and regional unions, or private entities to support the development of developing countries, as a consequence also of Albania as one of them. Its main reason is decreasing poverty and encouraging development. Many literatures reveal evidences of the impact these financial aids have on the economic growth of a country. This paper creates a link between the research done and the practice by making a detailed description of the phenomena and making clear how the effects are derived. It further analyzes the economic development of Albania in terms of net income during the last 30 years, and the corresponding financial aid allocation for each year. Starting with the interpretation of the financial aid amount allocated each year; this research paper also extends the information regarding the fields of economy where this aid is invested. The descriptive statistics shows that financial aid has noticeably increased from year to year and its impact on the economy as well.

The Management Accounting Practices in Albania in the Context of Globalization

Directory of Open Access Journals (Sweden)

Manjola Naco

2010-10-01

Full Text Available The main aim of the paper is to provide relevant findings on the status of management accounting in Albanian Accounting Practices, based on the direct survey with selected companies and individuals (experts on the field. In our analysis we have used as a benchmark the IFAC statement on Management Accounting Concepts and its description of the evolution of management accounting. To achieve our objectives we prepared and provided to a large group of professional accountants (that mainly are dealing with bookkeeping and financial statement preparations a structured questionnaire, containing several questions on the status of the practices applied in Albania on management accounting. This survey was carried out during the first half of 2009. Findings of this paper are based on the answers given by 300 respondents. These answers point out that management accounting practices in Albania tend not to be complex and sophisticated. Budgeting, product profitability and financial performance measurement remain the central pillars, while other, most contemporary, management accounting techniques are sporadically used. There is also little evidence of management accounting concerned directly with "value creation".  

Public and private schoolteachers' differences in terms of job attitudes in Albania.

Buka, Migena; Bilgiç, Reyhan

2010-06-01

In the present study, the attitudinal differences between public and private schoolteachers in Albania were investigated. Since the type of the organization varies, one would expect different climates for the emergence of job attitudes--mainly job satisfaction, job involvement, and organizational commitment, the most frequently studied job attitudes in the industrial and organizational psychology literature. It was hypothesized that the private schoolteachers would be more satisfied than public schoolteachers, especially due to high levels of payment and other desirable conditions. However, the public schoolteachers will be more involved than the private schoolteachers since they have to justify their continued work under the undesirable conditions. The commitment level of the private schoolteachers will be higher than the public schoolteachers since there is usually high correlation between job satisfaction and organizational commitment. Data were gathered from a total of 429 teachers working in public (n = 254) and private (n = 175) schools in Albania, in high and middle schools. The data were analyzed using multivariate analysis of covariance with age as a covariate. The results indicated that the private schoolteachers were more satisfied, as expected, revealed a weaker job involvement and were more committed to their school than their colleagues in the public sector. The results were found to be in line with previous studies conducted in the west. However, this study is believed to have a potential contribution to the literature in general, and to the Albanian local literature in particular. To the knowledge of the authors, there has been no similar study in Albania. Discussion is provided along with the limitations of the study and suggestions for future research.

Cannabis products (marijuana, hashish, cannabis oil) are the most frequently abused illegal substances worldwide. Delta-9-tetrahydrocannabinol (THC) is the main psychoactive component of Cannabis sativa plant, whereas cannabidiol (CBD) and cannabinol (CBN) are other major but no psychoactive constituents. Many studies have already been carried out on these compounds and chemical research was encouraged due to the legal implications concerning the misuse of marijuana. The aim of this study was to determine THC, CBD and CBN in a significant number of cannabis samples of Albanian origin, where cannabis is the most frequently used drug of abuse, in order to evaluate and classify them according to their cannabinoid composition. A GC-MS method was used, in order to assay cannabinoid content of hemp samples harvested at different maturation degree levels during the summer months and grown in different areas of Albania. This method can also be used for the determination of plant phenotype, the evaluation of psychoactive potency and the control of material quality. The highest cannabinoid concentrations were found in the flowers of cannabis. The THC concentrations in different locations of Albania ranged from 1.07 to 12.13%. The influence of environmental conditions on cannabinoid content is discussed. The cannabinoid content of cannabis plants were used for their profiling, and it was used for their classification, according to their geographical origin. The determined concentrations justify the fact that Albania is an area where cannabis is extensively cultivated for illegal purposes. Copyright © 2012 Elsevier Ireland Ltd. All rights reserved.

The influence of women's empowerment on maternal health care utilization: evidence from Albania.

Science.gov (United States)

Sado, Lantona; Spaho, Alma; Hotchkiss, David R

2014-08-01

Women in Albania receive antenatal care and postnatal care at lower levels than in other countries in Europe. Moreover, there are large socio-economic and regional disparities in maternal health care use. Previous research in low- and middle-income countries has found that women's status within the household can be a powerful force for improving the health, longevity, and mental and physical capacity of mothers and the well-being of children, but there is very little research on this issue in the Balkans. The aim of this paper is to investigate the influence of women's empowerment within the household on antenatal and postnatal care utilization in Albania. The research questions are explored through the use of bivariate and multivariate analyses based on nationally representative data from the 2008-09 Albania Demographic and Health Survey. The linkages between women's empowerment and maternal health care utilization are analyzed using two types of indicators of women's empowerment: decision making power and attitudes toward domestic violence. The outcome variables are indicators of the utilization of antenatal care and postnatal care. The findings suggest that use of maternal health care services is influenced by women's roles in decision-making and the attitudes of women towards domestic violence, after controlling for a number of socio-economic and demographic factors which are organized at individual, household, and community level. The study results suggest that policy actions that increase women's empowerment at home could be effective in helping assure good maternal health. Copyright © 2014 Elsevier Ltd. All rights reserved.

Antibacterial Resistance in African Catfish Aquaculture: a Review

Directory of Open Access Journals (Sweden)

Madubuike U. ANYANWU

2016-03-01

Full Text Available Antibacterial resistance (AR is currently one of the greatest threats to mankind as it constitutes health crisis. Extensive use of antibacterial agents in human and veterinary medicine, and farm crops have resulted in emergence of antibacterial-resistant organisms in different environmental settings including aquaculture. Antibacterial resistance in aquaculture is a serious global concern because antibacterial resistance genes (ARGs can be transferred easily from aquaculture setting to other ecosystems and the food chain. African catfish (ACF aquaculture has increased at a phenomenal rate through a continuous process of intensification, expansion and diversification. Risk of bacterial diseases has also increased and consequently there is increased use of antibacterial agents for treatment. Antibacterial resistance in ACF aquaculture has huge impact on the food chain and thus represents risk to public and animal health. In “one health” approach of curbing AR, knowledge of the sources, mechanisms and magnitude of AR in ACF aquaculture and its potential impact on the food chain is important in designing and prioritizing monitoring programs that may generate data that would be relevant for performing quantitative risk assessments, implementation of antibacterial stewardship plans, and developing effective treatment strategies for the control of ACF disease and reducing risk to public health. This review provides insight on the sources, mechanisms, prevalence and impact of antibacterial resistance in ACF aquaculture environment, a setting where the impact of AR is neglected or underestimated.

In addition, the research involves the analysis of work completed and documents produced as a result of the 2009-2011 Trans-European Mobility Program for University Studies (TEMPUS Project “Development of Master Study Programs in Education” (DEMED. The article outlines the similarities and differences of teacher education systems in Kosovo and Albania and emphasizes the need for small countries to co-operate on joint reform that leads to wider regional impact and facilitates mobility of staff and students. Identifying common goals is thus important. The two priority goals for these two countries are: development of practice and research-based teacher education. Conclusions are presented with the intent of findings being extrapolated to similar small, developing countries.

Full Text Available Autonomy of public health insurance scheme comprises political, financial, organizational, normative and contractual aspects. The paper analyses the role and position of a health insurance scheme (HIS within the overall healthcare system in Albania, the relationship to all other institutions, stakeholders and actors. By analyesing published literature and collected data through secondary sources, the paper focuses on financial autonomy, which refers first of all to a certain level of budgetary independence regarding source generation and spending on health services. For assuring effective and efficient performance of the single payer for health care services in Albania, need effective changes in the legislation do take into account the various levels of autonomy mentioned above.

Nearly half of all seafood consumed globally comes from aquaculture, a method of food production that has expanded rapidly in recent years. Increasing seafood consumption has been proposed as part of a strategy to combat the current non-communicable disease (NCD) pandemic, but public health, environmental, social, and production challenges related to certain types of aquaculture production must be addressed. Resolving these complicated human health and ecologic trade-offs requires systems thinking and collaboration across many fields; the One Health concept is an integrative approach that brings veterinary and human health experts together to combat zoonotic disease. We propose applying and expanding the One Health approach to facilitate collaboration among stakeholders focused on increasing consumption of seafood and expanding aquaculture production, using methods that minimize risks to public health, animal health, and ecology. This expanded application of One Health may also have relevance to other complex systems with similar trade-offs.

2015-09-01

Full Text Available In Albania, during the last decades entrepreneurship has been in focus. It is commonly agreed that developing entrepreneurship in the long term would be translated into sustainable economic development. Albanian economy, being an economy in transition greatly and urgently needs to invest into increasing the number of entrepreneurs in the country. Entrepreneurial intention is considered to be really important. Thus, the purpose of this paper is to observe the determinants of entrepreneurial intention in Albania. The target is university students. Many programs that foster entrepreneurship such as incubator centers, business plan competitions along with new educational practices have been developed. In addition, even though studies conducting in this field are few, Albanian education institutions have shown a willing to study the factors influencing entrepreneurship development. The reason is the belief that developing and supporting entrepreneurial activities among youth will positively influence the economy of the country in terms of economic growth. This study widely represents the Albanian students and shows the deteminants of entrepreneurial intention they have. Hopefully the findings of this study would be useful to the policy makers and the Albanian government to undertake effective policies focused on entrepreneurial activity; targeting economic development of the country.

Full Text Available Albania has potential for developing the organic agriculture sector; however, it is a new industry and constraints abound including lack of consumer preferences information for organic food. Knowledge on consumer preferences and behaviour toward organic (bio products is crucial for market development benefiting potential entrepreneurs and government policies. They need to know the preference for preferred product attributes and willingness to pay. Tomato, which is the most important vegetable in terms of consumption and production in Albania, is the subject of this study. A conjoint choice experiment with the most important product attributes: production type (bio vs. conventional, production system (open field vs. greenhouse, origin and price were used to design the choice surveys. Four distinct classes have been identified as significant using latent class analysis. The classes are summarized as: bio-ready consumers, price sensitive consumers, variety seeking consumers and quality seeking consumers. Origin played a small influence on preference. Education and income did show some influence on preference for organic tomatoes. Although the organic food market in Albania is in its infancy stage, organic tomatoes are clearly preferred and many consumers are willing to pay a premium price.

Aquaculture has many occupational hazards, including those that are physical, chemical, biological, ergonomic, and mechanical. The risks in aquaculture are inherent, as this activity requires particular practices. The objective of the present study was to show the risks associated with the aquaculture sector and present a critical overview on the Brazilian public policies concerning aquaculture occupational health. Methods include online research involved web searches and electronic databases including Pubmed, Google Scholar, Scielo and government databases. We conducted a careful revision of Brazilian labor laws related to occupational health and safety, rural workers, and aquaculture. The results and conclusion support the idea that aquaculture requires specific and well-established industry programs and policies, especially in developing countries. Aquaculture still lacks scientific research, strategies, laws, and public policies to boost the sector with regard to occupational health and safety. The establishment of a safe workplace in aquaculture in developing countries remains a challenge for all involved in employer-employee relationships.

2010-03-01

Full Text Available Economic cooperation and trade between countries of region is very important as a opening step for entering in big markets like EU-s. All agreements have a huge impact in customs administration for elimination of customs taxes and for facilitation of trade during customs crossing. Trade integration is seen as faster way for countries to complete all necessary condition for European Integration. This process requires fulfillment of all reforms, needed for approaches the development and integration between countries. This process is spread in time because of the feature and difference between society and their economies. Regional economic integration is considered an import component for longterm integration of South Eastern European countries in EU. Membership of Albania in WTO brings a number of free trade agreements, with the main purpose trade liberalization. The essences of these agreements have been liberalization of customs tariffs for increasing foreign trade and attract foreign investors. The loss of customs income will be compensating from imports increasing and economic development in general. The role of Customs has changed from one of a complete focus on revenue collection to a broad role encompassing components of revenue collection, trade facilitation and border security. Simplified customs procedures and documents are very important for improving relation of business and government and also improving business performance. The aim of this paper is to point out the roles, responsibilities and challenges of customs, for concluding this we have conducted a survey for analyzing the performance of customs in Albania.  

The impact of tobacco control policies in Albania.

Zaloshnja, Eduard; Ross, Hana; Levy, David T

2010-12-01

To assess the impact of a tobacco control law adopted in Albania in 2007 and to estimate the share of illicit cigarettes on the market. Comparative analysis of two waves of a nationally representative household survey, one conducted before the new law went into effect and the other after 2 years. Official sales data were contrasted with the consumption estimate based on the survey. Smoking prevalence, quit attempts, exposure to cigarette advertising, exposure to second-hand smoke, total cigarette consumption, share of illicit packs among packs possessed by smokers. Despite the adoption of strong smoke-free policies and adverting restrictions, smoking prevalence in Albania has risen. The increase in prevalence has been driven by higher smoking rates among females (18.9% in 2007 vs 29.3% in 2009) and young adults (23.2% in 2007 vs 38.5% in 2009 among 18-19 year olds). Self-reported exposure to second-hand smoke and cigarette advertising have been reduced since 2007. The majority of respondents are still exposed to second-hand smoke and more than half are exposed to tobacco advertising. Nevertheless, there are signs that the consumption of illicit cigarettes is declining. The impacts of smoke-free policies and an advertising ban have been limited due to lack of enforcement and failure to adopt a comprehensive set of tobacco control measures. These measures should include sizeable and regular tobacco tax increases in excess of the general level of inflation and income growth. The decline in the share of illicit cigarettes should improve the effectiveness of the cigarette tax policy.

The potentials of rural tourism in developing rural areas in Albania

Directory of Open Access Journals (Sweden)

Henrietta Nagy

2017-12-01

Full Text Available The inspiration that drove us to this study is that conventional tourism in Albania is focused more on promoting seaside, cultural tourism, luxury resorts, etc. which has demonstrated a good trend. At the same time, specific parts of the country have been abandoned due to their underdeveloped situation. Given their assets as constructed and indigenous habitat, they progressively appear as regions for rural tourism development. It could provide good development opportunities in remote mountainous areas that every day more are abandoned by the population because they do not have enough employment opportunities. But as for other rural areas which have a great potential for development of rural tourism, they are not preferred by the population either to live because they do not have developed agriculture. They do not provide the opportunity to earn enough money to live on at the appropriate standard. So the development of rural tourism would help the population in such areas to diversify their activities and earn some extra income, motivating inhabitants to stay in their own areas. Overall, it would contribute to the balanced development of the regions of Albania.

Albania: Trends and patterns, proximate determinants and policies of fertility change

Directory of Open Access Journals (Sweden)

Letizia Mencarini

2008-07-01

Full Text Available For a very long time, Albania has had one of the highest levels of fertility in Europe: in 2002 the total fertility rate of 2.2 children per woman was the highest in Europe. Although this current level is high, the country has experienced a rapid fertility reduction during the last 50 years: a TFR decline from 7 to 2.2. This reduction has occurred in the absence of modern contraception and abortion, which indicates the significance of investments in the social agenda during the communist regime that produced policies with indirect effects on fertility. Most significant of these were policies focused on education, in particular on female education. Social and demographic settings for a further fertility reduction in Albania have been present since 1990. Contraception and abortion have been legalized and available since the early 1990s, but knowledge of their use is still not widespread in the country, largely due to the interplay between traditional and modern norms of Albanian society. This chapter points out that future fertility levels will be determined not only by new policies that might be introduced, but predominantly by the balance of this interplay.

Adherence to a predominantly Mediterranean diet decreases the risk of gastroesophageal reflux disease: a cross-sectional study in a South Eastern European population.

2016-10-01

Our aim was to assess the association of a Mediterranean diet and gastroesophageal reflux disease among adult men and women in Albania, a former communist country in South Eastern Europe with a predominantly Muslim population. A cross-sectional study was conducted in 2012, which included a population-based sample of 817 individuals (≥18 years) residing in Tirana, the Albanian capital (333 men; overall mean age: 50.2 ± 18.7 years; overall response rate: 82%). Assessment of gastroesophageal reflux disease was based on Montreal definition. Participants were interviewed about their dietary patterns, which in the analysis was dichotomized into: predominantly Mediterranean (frequent consumption of composite/traditional dishes, fresh fruit and vegetables, olive oil, and fish) versus largely non-Mediterranean (frequent consumption of red meat, fried food, sweets, and junk/fast food). Logistic regression was used to assess the association of gastroesophageal reflux disease with the dietary patterns. Irrespective of demographic and socioeconomic characteristics and lifestyle factors including eating habits (meal regularity, eating rate, and meal-to-sleep interval), employment of a non-Mediterranean diet was positively related to gastroesophageal reflux disease risk (fully adjusted odds ratio = 2.3, 95% confidence interval = 1.2-4.5). Our findings point to a beneficial effect of a Mediterranean diet in the occurrence of gastroesophageal reflux disease in transitional Albania. Findings from this study should be confirmed and expanded further in prospective studies in Albania and in other Mediterranean countries. © 2015 International Society for Diseases of the Esophagus.

Eriseida Ndoni

2016-02-01

Full Text Available BACKGROUND: Preeclampsia is a hypertensive multisystem disorder of pregnancy that complicates up to 10% of pregnancies worldwide and is one of the leading causes of maternal and perinatal morbidity and mortality. AIM: To evaluate maternal complications associated with severe preeclampsia. METHODS: This is a retrospective cross-sectional study conducted in the UHOG “Koço Gliozheni”, in Tirana. Primary outcomes evaluated: maternal death, eclampsia, stroke, HELLP syndrome, and pulmonary edema. Secondary outcomes: renal failure, admission in ICU, caesarean section, placental abruption, and postpartum hemorrhage. Fisher’s exact test and Chi-squared test were used as statistical methods. RESULTS: In women with severe preeclampsia we found higher rates of complications comparing to the group with preeclampsia. Eclampsia (1.5% vs. 7.1%, P < 0.001, HELLP syndrome (2.4% vs. 11.0%; P < 0.001, stroke (0.5% vs 1.9%, P = 0.105 pulmonary edema (0.25% vs. 1.3%, P = 0.0035, renal failure (0.9% vs. 2.6%, P = 0.107, admission in ICU (19.5% vs. 71.4%, P = 0.007, caesarean section rates (55.5% vs. 77%, P = 0.508, placental abruption (4.3% vs. 7.8%, P = 0.103 and severe postpartum hemorrhage (3.2% vs. 3.9%, P = 0.628. CONCLUSION: Severe preeclampsia is associated with high rates of maternal severe morbidity and early diagnosis and timely intervention can prevent life treating complications.

The objective of this project is to establish a basic gravity network in Albania, Kosovo and Montenegro to enable further investigations in geodetic and geophysical issues. Therefore the first time in history absolute gravity measurements were performed in these countries. The Norwegian mapping authority Kartverket is assisting the national mapping authorities in Kosovo (KCA) (Kosovo Cadastral Agency - Agjencia Kadastrale e Kosovës), Albania (ASIG) (Autoriteti Shtetëror i Informacionit Gjeohapësinor) and in Montenegro (REA) (Real Estate Administration of Montenegro - Uprava za nekretnine Crne Gore) in improving the geodetic frameworks. The gravity measurements are funded by Kartverket. The absolute gravimetric measurements were performed from BEV (Federal Office of Metrology and Surveying) with the absolute gravimeter FG5-242. As a national metrology institute (NMI) the Metrology Service of the BEV maintains the national standards for the realisation of the legal units of measurement and ensures their international equivalence and recognition. Laser and clock of the absolute gravimeter were calibrated before and after the measurements. The absolute gravimetric survey was carried out from September to October 2015. Finally all 8 scheduled stations were successfully measured: there are three stations located in Montenegro, two stations in Kosovo and three stations in Albania. The stations are distributed over the countries to establish a gravity network for each country. The vertical gradients were measured at all 8 stations with the relative gravimeter Scintrex CG5. The high class quality of some absolute gravity stations can be used for gravity monitoring activities in future. The measurement uncertainties of the absolute gravity measurements range around 2.5 micro Gal at all stations (1 microgal = 10-8 m/s2). In Montenegro the large gravity difference of 200 MilliGal between station Zabljak and Podgorica can be even used for calibration of relative gravimeters

Antimicrobials used in salmon aquaculture pass into the marine environment. This could have negative impacts on marine environmental biodiversity, and on terrestrial animal and human health as a result of selection for bacteria containing antimicrobial resistance genes. We therefore measured the numbers of culturable bacteria and antimicrobial-resistant bacteria in marine sediments in the Calbuco Archipelago, Chile, over 12-month period at a salmon aquaculture site approximately 20 m from a salmon farm and at a control site 8 km distant without observable aquaculture activities. Three antimicrobials extensively used in Chilean salmon aquaculture (oxytetracycline, oxolinic acid, and florfenicol) were studied. Although none of these antimicrobials was detected in sediments from either site, traces of flumequine, a fluoroquinolone antimicrobial also widely used in Chile, were present in sediments from both sites during this period. There were significant increases in bacterial numbers and antimicrobial-resistant fractions to oxytetracycline, oxolinic acid, and florfenicol in sediments from the aquaculture site compared to those from the control site. Interestingly, there were similar numbers of presumably plasmid-mediated resistance genes for oxytetracycline, oxolinic acid and florfenicol in unselected marine bacteria isolated from both aquaculture and control sites. These preliminary findings in one location may suggest that the current use of large amounts of antimicrobials in Chilean aquaculture has the potential to select for antimicrobial-resistant bacteria in marine sediments.

Mortgage lending and house prices in Albania - a co-integrated analysis based on VECM

Directory of Open Access Journals (Sweden)

Erjona REBI

2014-06-01

Full Text Available The general view that the banks’ lending plays a crucial role in the real estate market was again confirmed during the recent financial crisis. During the precrisis period, house prices in Albania increased rapidly, supported also by a fast expansion of mortgage lending. This study aims to empirically analyse the relation between housing prices and banks’ financing in the long run, referring to a VECM model. The estimated results confirm the important role of mortgage to house prices. Meanwhile, the relation between house prices and interest rates resulted statistically insignificant. Unlike the previous literature, exchange rate has been included as an endogenous variable. Results show positive correlation and statistical significance between house prices and exchange rate. Finally, this paper is expected to contribute to the literature as there are very few studies that elaborate on the macroeconomic factors’ influence on the housing prices in Albania.

Economics of Tertiary Education - Challenges and dynamics of the public tertiary education in Albania

Gledian Llatja

2016-07-01

Full Text Available The tertiary education is a critic mechanism for the socio-economic progress, for individuals who aspire a brighter future and it is also considered an important catalyzer of the economic mobility (Department of Treasury and Department of Education, 2012, 2. Based on the positive role and impact that the tertiary education has on the sustainable development, President Obama once stated that it is of damage to treat education as a luxurious public service. In line with the general considerations about the tertiary education in the U.S. the parallel comparison with Albania comes as a direct interpretation of utopia in the education policy-making. As policies are usually drafted based on data and findings, in the case of Albania there is a lack of data on expenses on tertiary education as share of GDP. This stands also for the main limitation of the paper.

Nitrous oxide (N2O) emission from aquaculture: a review.

Science.gov (United States)

Hu, Zhen; Lee, Jae Woo; Chandran, Kartik; Kim, Sungpyo; Khanal, Samir Kumar

2012-06-19

Nitrous oxide (N(2)O) is an important greenhouse gas (GHG) which has a global warming potential 310 times that of carbon dioxide (CO(2)) over a hundred year lifespan. N(2)O is generated during microbial nitrification and denitrification, which are common in aquaculture systems. To date, few studies have been conducted to quantify N(2)O emission from aquaculture. Additionally, very little is known with respect to the microbial pathways through which N(2)O is formed in aquaculture systems. This review suggests that aquaculture can be an important anthropogenic source of N(2)O emission. The global N(2)O-N emission from aquaculture in 2009 is estimated to be 9.30 × 10(10) g, and will increase to 3.83 × 10(11)g which could account for 5.72% of anthropogenic N(2)O-N emission by 2030 if the aquaculture industry continues to increase at the present annual growth rate (about 7.10%). The possible mechanisms and various factors affecting N(2)O production are summarized, and two possible methods to minimize N(2)O emission, namely aquaponic and biofloc technology aquaculture, are also discussed. The paper concludes with future research directions.

Aquaculture is the fastest growing food sector and continues to expand alongside terrestrial crop and livestock production. Using portfolio theory as a conceptual framework, we explore how current interconnections between the aquaculture, crop, livestock, and fisheries sectors act as an impediment to, or an opportunity for, enhanced resilience in the global food system given increased resource scarcity and climate change. Aquaculture can potentially enhance resilience through improved resource use efficiencies and increased diversification of farmed species, locales of production, and feeding strategies. However, aquaculture's reliance on terrestrial crops and wild fish for feeds, its dependence on freshwater and land for culture sites, and its broad array of environmental impacts diminishes its ability to add resilience. Feeds for livestock and farmed fish that are fed rely largely on the same crops, although the fraction destined for aquaculture is presently small (∼4%). As demand for high-value fed aquaculture products grows, competition for these crops will also rise, as will the demand for wild fish as feed inputs. Many of these crops and forage fish are also consumed directly by humans and provide essential nutrition for low-income households. Their rising use in aquafeeds has the potential to increase price levels and volatility, worsening food insecurity among the most vulnerable populations. Although the diversification of global food production systems that includes aquaculture offers promise for enhanced resilience, such promise will not be realized if government policies fail to provide adequate incentives for resource efficiency, equity, and environmental protection.

Marketing netcoatings for aquaculture.

Science.gov (United States)

Martin, Robert J

2014-10-17

Unsustainable harvesting of natural fish stocks is driving an ever growing marine aquaculture industry. Part of the aquaculture support industry is net suppliers who provide producers with nets used in confining fish while they are grown to market size. Biofouling must be addressed in marine environments to ensure maximum product growth by maintaining water flow and waste removal through the nets. Biofouling is managed with copper and organic biocide based net coatings. The aquaculture industry provides a case study for business issues related to entry of improved fouling management technology into the marketplace. Several major hurdles hinder entry of improved novel technologies into the market. The first hurdle is due to the structure of business relationships. Net suppliers can actually cut their business profits dramatically by introducing improved technologies. A second major hurdle is financial costs of registration and demonstration of efficacy and quality product with a new technology. Costs of registration are prohibitive if only the net coatings market is involved. Demonstration of quality product requires collaboration and a team approach between formulators, net suppliers and farmers. An alternative solution is a vertically integrated business model in which the support business and product production business are part of the same company.

PROTEOMICS in aquaculture: applications and trends.

Science.gov (United States)

Rodrigues, Pedro M; Silva, Tomé S; Dias, Jorge; Jessen, Flemming

2012-07-19

Over the last forty years global aquaculture presented a growth rate of 6.9% per annum with an amazing production of 52.5 million tonnes in 2008, and a contribution of 43% of aquatic animal food for human consumption. In order to meet the world's health requirements of fish protein, a continuous growth in production is still expected for decades to come. Aquaculture is, though, a very competitive market, and a global awareness regarding the use of scientific knowledge and emerging technologies to obtain a better farmed organism through a sustainable production has enhanced the importance of proteomics in seafood biology research. Proteomics, as a powerful comparative tool, has therefore been increasingly used over the last decade to address different questions in aquaculture, regarding welfare, nutrition, health, quality, and safety. In this paper we will give an overview of these biological questions and the role of proteomics in their investigation, outlining the advantages, disadvantages and future challenges. A brief description of the proteomics technical approaches will be presented. Special focus will be on the latest trends related to the aquaculture production of fish with defined nutritional, health or quality properties for functional foods and the integration of proteomics techniques in addressing this challenging issue.

The use of probiotics in aquaculture.

Science.gov (United States)

Hai, N V

2015-10-01

This study aims to present comprehensive notes for the use of probiotics in aquaculture. Probiotics have been proven to be positive promoters of aquatic animal growth, survival and health. In aquaculture, intestines, gills, the skin mucus of aquatic animals, and habitats or even culture collections and commercial products, can be sources for acquiring appropriate probiotics, which have been identified as bacteria (Gram-positive and Gram-negative) and nonbacteria (bacteriophages, microalgae and yeasts). While a bacterium is a pathogen to one aquatic animal, it can bring benefits to another fish species; a screening process plays a significant role in making a probiotic species specific. The administration of probiotics varies from oral/water routine to feed additives, of which the latter is commonly used in aquaculture. Probiotic applications can be either mono or multiple strains, or even in combination with prebiotic, immunostimulants such as synbiotics and synbiotism, and in live or dead forms. Encapsulating probiotics with live feed is a suitable approach to convey probiotics to aquatic animals. Dosage and duration of time are significant factors in providing desired results. Several modes of actions of probiotics are presented, while some others are not fully understood. Suggestions for further studies on the effects of probiotics in aquaculture are proposed. © 2015 The Society for Applied Microbiology.

Aquaculture's pressure on forage fisheries remains hotly contested. This article reviews trends in fishmeal and fish oil use in industrial aquafeeds, showing reduced inclusion rates but greater total use associated with increased aquaculture production and demand for fish high in long-chain omega-3 oils. The ratio of wild fisheries inputs to farmed fish output has fallen to 0.63 for the aquaculture sector as a whole but remains as high as 5.0 for Atlantic salmon. Various plant- and animal-based alternatives are now used or available for industrial aquafeeds, depending on relative prices and consumer acceptance, and the outlook for single-cell organisms to replace fish oil is promising. With appropriate economic and regulatory incentives, the transition toward alternative feedstuffs could accelerate, paving the way for a consensus that aquaculture is aiding the ocean, not depleting it.

Offshore Aquaculture: I Know It When I See It

Directory of Open Access Journals (Sweden)

Halley E. Froehlich

2017-05-01

Full Text Available Offshore aquaculture is increasingly viewed as a mechanism to meet growing protein demand for seafood, while minimizing adverse consequences on the environment and other uses in the oceans. However, despite growing interest in offshore aquaculture, there appears to be no consensus as to what measures commonly define an offshore site or how effects of offshore aquaculture—relative to more nearshore practices—are assessed. This lack of agreement on what constitutes offshore aquaculture has the potential to convolute communication, create uncertainty in regulatory processes, and impede understanding of the ecological implications of offshore farming. To begin addressing these issues, we reviewed and analyzed biologically-focused primary and gray literature (Ntotal = 70 that categorize and quantify characteristics of offshore aquaculture from around the world. We found that many “offshore” descriptions are relatively close to shore (<3 nm and significantly shallower (minimum depth ≤30 m than may be assumed. We also uncovered an overall lack of consistent reporting of even the most common location-focused metrics (distance from shore, depth, current, a dearth of impact related studies (n = 17, and narrow scope of the studies themselves (i.e., 82% nutrient pollution. Of the finite subset of articles that investigated negative ecological impacts of offshore aquaculture, we found the probability of any measurable impact from an offshore farm appears to significantly decrease with distance from the farm (probability of measurable response at 90 m ± SE = 0.01 ± 0.03. Such general, but informative points of reference could be more robustly quantified with better systematic and standardized reporting of physical farm characteristics and a broader scope of ecological investigation into the effects of marine aquaculture. With offshore aquaculture still in its infancy, consistent metrics are needed for a comparable framework to guide sustainable

Hybrid governance of aquaculture: Opportunities and challenges.

Science.gov (United States)

Vince, Joanna; Haward, Marcus

2017-10-01

The development of third party assessment and certification of fisheries and aquaculture has provided new forms of governance in sectors that were traditionally dominated by state based regulation. Emerging market based approaches are driven by shareholder expectations as well as commitment to corporate social responsibility, whereas community engagement is increasingly centered on the questions of social license to operate. Third party assessment and certification links state, market and community into an interesting and challenging hybrid form of governance. While civil society organizations have long been active in pursuing sustainable and safe seafood production, the development of formal non-state based certification provides both opportunities and challenges, and opens up interesting debates over hybrid forms of governance. This paper explores these developments in coastal marine resources management, focusing on aquaculture and the development and operation of the Aquaculture Stewardship Council. It examines the case of salmonid aquaculture in Tasmania, Australia, now Australia's most valuable seafood industry, which remains the focus of considerable community debate over its siting, operation and environmental impact.

Problems of large-scale vertically-integrated aquaculture

Energy Technology Data Exchange (ETDEWEB)

Webber, H H; Riordan, P F

1976-01-01

The problems of vertically-integrated aquaculture are outlined; they are concerned with: species limitations (in the market, biological and technological); site selection, feed, manpower needs, and legal, institutional and financial requirements. The gaps in understanding of, and the constraints limiting, large-scale aquaculture are listed. Future action is recommended with respect to: types and diversity of species to be cultivated, marketing, biotechnology (seed supply, disease control, water quality and concerted effort), siting, feed, manpower, legal and institutional aids (granting of water rights, grants, tax breaks, duty-free imports, etc.), and adequate financing. The last of hard data based on experience suggests that large-scale vertically-integrated aquaculture is a high risk enterprise, and with the high capital investment required, banks and funding institutions are wary of supporting it. Investment in pilot projects is suggested to demonstrate that large-scale aquaculture can be a fully functional and successful business. Construction and operation of such pilot farms is judged to be in the interests of both the public and private sector.

High-resolution molecular epidemiology and evolutionary history of HIV-1 subtypes in Albania.

Directory of Open Access Journals (Sweden)

Marco Salemi

2008-01-01

Full Text Available HIV-1 epidemic in Western Europe is largely due to subtype B. Little is known about the HIV-1 in Eastern Europe, but a few studies have shown that non-B subtypes are quite common. In Albania, where a recent study estimated a ten-fold increase of AIDS incidence during the last six years, subtype A and B account for 90% of the know infections.We investigated the demographic history of HIV-1 subtype A and B in Albania by using a statistical framework based on coalescent theory and phylogeography. High-resolution phylogenetic and molecular clock analysis showed a limited introduction to the Balkan country of subtype A during the late 1980s followed by an epidemic outburst in the early 1990 s. In contrast, subtype B was apparently introduced multiple times between the mid-1970s and mid-1980s. Both subtypes are growing exponentially, although the HIV-1A epidemic displays a faster growth rate, and a significantly higher basic reproductive number R(0. HIV-1A gene flow occurs primarily from the capital Tirane, in the center of the country, to the periphery, while HIV-1B flow is characterized by a balanced exchange between center and periphery. Finally, we calculated that the actual number of infections in Albania is at least two orders of magnitude higher than previously thought.Our analysis demonstrates the power of recently developed computational tools to investigate molecular epidemiology of pathogens, and emphasize the complex factors involved in the establishment of HIV-1 epidemics. We suggest that a significant correlation exists between HIV-1 exponential spread and the socio-political changes occurred during the Balkan wars. The fast growth of a relatively new non-B epidemic in the Balkans may have significant consequences for the evolution of HIV-1 epidemiology in neighboring countries in Eastern and Western Europe.

Full Text Available As competitiveness is growing in the Balkans, a new approach in the development of heritage tourism, which can adapt to these circumstances, is required. Cluster practices can be the new approach that can improve competitiveness of Albanian tourism. Considering the nature of Albania and its rich heritage, it is a very attractive “magnet” for foreign tourists. The article starts with a presentation of tourism experience in Albania and discusses why heritage tourism is possibly the only way to develop tourism now and for the future, in the country. Some brief explanation concerning cluster practices follow: a presentation of the main issues about cluster practices, their benefits and drawbacks, their implementation and the ways they can be monitored and evaluated. It is important to direct attention to the fact that cluster practices are becoming an important means to development and to the enforcement of social capital in the geographical areas where they are implemented. In the end of the article is shown why cluster practices can be worth of being implemented in area of Butrint-Saranda-Gjirokastra-Korca. The paper concludes with the main findings and conclusions of the analysis.

The Application of Integrated Multi Trophic Aquaculture (IMTA Using Stratified Double Net Rounded Cage (SDFNC for Aquaculture Sustainability

Directory of Open Access Journals (Sweden)

Sapto P. Putro

2015-12-01

Full Text Available The increase of fishery production nationally and internationally may impact on the potential emergence of a variety of environmental problems. The application of sustainable aquaculture is urgently needed by breeding fish for commercial purposes in a manner such that it has a minimum impact on the environment, contributing to the development of local communities and generating economic benefits. The design of the cage and farming practice in aquaculture activities are the important steps to ensure that farming activity is still observed in order to anticipate the risk of organic enrichment caused by the activities. The application of Integrated Multi-Trophic Aquaculture  (IMTA on the Stratified Double Floating Net Cage  (SDFNC integrated with biomonitoring are an appropriate solution to the ongoing productive farming practices. IMTA is an aquaculture practice using more than one species of biotas which have ecologically mutual relationship as a part of the food chain in the area at the same time. The application of IMTA allows farmers to get several aquaculture products in the same area without increasing the horizontal area of the farms. At first, the SDFNC has been applied for farming Cyprinus carpio and Tilapia niloticus as polyculture system in freshwater ecosystem of Rawapening Lake, Central Java. Its operation has been able to increase the production capacity of at least 75% of conventional cages. The application of SDFNC-IMTA using milkfish (Chanos Chanos, seaweed (Kappaphycus alvarezii, and white shrimp (Litopenaeus vannamei has been able to minimize the impact and maintain the water ecosystem in the Gulf Awerange, South Sulawesi.

Mechanisms of quorum sensing and strategies for quorum sensing disruption in aquaculture pathogens.

Science.gov (United States)

Zhao, J; Chen, M; Quan, C S; Fan, S D

2015-09-01

In many countries, infectious diseases are a considerable threat to aquaculture. The pathogenicity of micro-organisms that infect aquaculture systems is closely related to the release of virulence factors and the formation of biofilms, both of which are regulated by quorum sensing (QS). Thus, QS disruption is a potential strategy for preventing disease in aquaculture systems. QS inhibitors (QSIs) not only inhibit the expression of virulence-associated genes but also attenuate the virulence of aquaculture pathogens. In this review, we discuss QS systems in important aquaculture pathogens and focus on the relationship between QS mechanisms and bacterial virulence in aquaculture. We further elucidate QS disruption strategies for targeting aquaculture pathogens. Four main types of QSIs that target aquaculture pathogens are discussed based on their mechanisms of action. © 2014 John Wiley & Sons Ltd.

Possibilities for marker-assisted selection in aquaculture breeding schemes

International Nuclear Information System (INIS)

Sonesson, A.K.

2007-01-01

FAO estimates that there are around 200 species in aquaculture. However, only a few species have ongoing selective breeding programmes. Marker-assisted selection (MAS) is not used in any aquaculture breeding scheme today. The aim of this chapter, therefore, is to review briefly the current status of aquaculture breeding schemes and to evaluate the possibilities for MAS of aquaculture species. Genetic marker maps have been published for some species in culture. The marker density of these maps is, in general, rather low and the maps are composed of many amplified fragment length polymorphism (AFLP) markers anchored to few microsatellites. Some quantitative trait loci (QTL) have been identified for economically important traits, but they are not yet mapped at a high density. Computer simulations of within-family MAS schemes show a very high increase in genetic gain compared with conventional family-based breeding schemes, mainly due to the large family sizes that are typical for aquaculture breeding schemes. The use of genetic markers to identify individuals and their implications for breeding schemes with control of inbreeding are discussed. (author)

2016-01-01

Full Text Available The administration of antimicrobials in aquaculture provides a selective pressure creating a reservoir of multiple resistant bacteria in the cultured fish and shrimps as well as the aquaculture environment. The objective of this study was to determine the extent of antibiotic resistance in aquaculture products and aquaculture’s surrounding environment in Sarawak, Malaysian Borneo. Ninety-four identified bacterial isolates constituted of 17 genera were isolated from sediment, water, and cultured organisms (fish and shrimp in selected aquaculture farms. These isolates were tested for their antibiotic resistance against 22 antibiotics from several groups using the disk diffusion method. The results show that the highest resistance was observed towards streptomycin (85%, n=20, while the lowest resistance was towards gentamicin (1.1%, n=90. The multiple antibiotic resistant (MAR index of the isolates tested ranged between 0 and 0.63. It was suggested that isolates with MAR index > 0.2 were recovered from sources with high risk of antibiotic resistant contamination. This study revealed low level of antibiotic resistance in the aquaculture bacterial isolates except for streptomycin and ampicillin (>50% resistance, n=94 which have been used in the aquaculture industry for several decades. Antibiotic resistant patterns should be continuously monitored to predict the emergence and widespread of MAR. Effective action is needed to keep the new resistance from further developing and spreading.

Japanese aquaculture with thermal water from power plants

International Nuclear Information System (INIS)

Kuroda, T.

1977-01-01

The present level of thermal aquaculture, utilizing thermal water which is waste cooling water from nuclear power plant, in Japan is reported. There are 13 major potential areas for thermal aquaculture in cooperation with conventional type thermal power plants, seven of which are actually operating. Aquaculture facilities of all these are on land, none in the sea. Of these seven centers, those that have already commercialized their nursery methods or are approaching that stage of research and development, are Tohoku Hatsuden Kogyo Ltd., Tsuruga Hama Land Ltd. and Kyushu Rinsan Ltd. Major problems faced specialists in Japanese thermal aquaculture are water temperature, water quality, radioactivity and costs. For keeping the water temperature constant all seasons, cooling or heating by natural sea water may be used. Even negligible amounts of radioactivity that nuclear power plants release into the sea will concentrate in the systems of marine life. A strict precautionary checking routine is used to detect radioactivity in marine life. (Kobatake, H.)

Can greening of aquaculture sequester blue carbon?

Science.gov (United States)

Ahmed, Nesar; Bunting, Stuart W; Glaser, Marion; Flaherty, Mark S; Diana, James S

2017-05-01

Globally, blue carbon (i.e., carbon in coastal and marine ecosystems) emissions have been seriously augmented due to the devastating effects of anthropogenic pressures on coastal ecosystems including mangrove swamps, salt marshes, and seagrass meadows. The greening of aquaculture, however, including an ecosystem approach to Integrated Aquaculture-Agriculture (IAA) and Integrated Multi-Trophic Aquaculture (IMTA) could play a significant role in reversing this trend, enhancing coastal ecosystems, and sequestering blue carbon. Ponds within IAA farming systems sequester more carbon per unit area than conventional fish ponds, natural lakes, and inland seas. The translocation of shrimp culture from mangrove swamps to offshore IMTA could reduce mangrove loss, reverse blue carbon emissions, and in turn increase storage of blue carbon through restoration of mangroves. Moreover, offshore IMTA may create a barrier to trawl fishing which in turn could help restore seagrasses and further enhance blue carbon sequestration. Seaweed and shellfish culture within IMTA could also help to sequester more blue carbon. The greening of aquaculture could face several challenges that need to be addressed in order to realize substantial benefits from enhanced blue carbon sequestration and eventually contribute to global climate change mitigation.

Alien species in aquaculture and biodiversity: a paradox in food production.

Science.gov (United States)

De Silva, Sena S; Nguyen, Thuy T T; Turchini, Giovanni M; Amarasinghe, Upali S; Abery, Nigel W

2009-02-01

Aquaculture is seen as an alternative to meeting the widening gap in global rising demand and decreasing supply for aquatic food products. Asia, the epicenter of the global aquaculture industry, accounts for over 90% of the global aquaculture production quantity and about 80% of the value. Asian aquaculture, as with global aquaculture, is dependent to a significant extent on alien species, as is the case for all the major food crops and husbanded terrestrial animals. However, voluntary and or accidental introduction of exotic aquatic species (alien species) is known to negatively impact local biodiversity. In this relatively young food production industry, mitigating the dependence on alien species, and thereby minimizing potential negative impacts on biodiversity, is an imperative for a sustainable future. In this context an attempt is made in this synthesis to understand such phenomena, especially with reference to Asian inland finfish, the mainstay of global aquaculture production. It is pointed out that there is potential for aquaculture, which is becoming an increasingly important food production process, not to follow the past path of terrestrial food crops and husbanded animals in regard to their negative influences on biodiversity.

Nutrient removal from Chinese coastal waters by large-scale seaweed aquaculture

KAUST Repository

Xiao, Xi

2017-04-21

China is facing intense coastal eutrophication. Large-scale seaweed aquaculture in China is popular, now accounting for over 2/3\\'s of global production. Here, we estimate the nutrient removal capability of large-scale Chinese seaweed farms to determine its significance in mitigating eutrophication. We combined estimates of yield and nutrient concentration of Chinese seaweed aquaculture to quantify that one hectare of seaweed aquaculture removes the equivalent nutrient inputs entering 17.8 ha for nitrogen and 126.7 ha for phosphorus of Chinese coastal waters, respectively. Chinese seaweed aquaculture annually removes approximately 75,000 t nitrogen and 9,500 t phosphorus. Whereas removal of the total N inputs to Chinese coastal waters requires a seaweed farming area 17 times larger than the extant area, one and a half times more of the seaweed area would be able to remove close to 100% of the P inputs. With the current growth rate of seaweed aquaculture, we project this industry will remove 100% of the current phosphorus inputs to Chinese coastal waters by 2026. Hence, seaweed aquaculture already plays a hitherto unrealized role in mitigating coastal eutrophication, a role that may be greatly expanded with future growth of seaweed aquaculture.

Rotavirus vaccines have been introduced in several European countries but can represent a considerable cost, particularly for countries that do not qualify for any external financial support. This study aimed to evaluate the cost-effectiveness of introducing rotavirus vaccination into Albania's national immunization program and to inform national decision-making by improving national capacity to conduct economic evaluations of new vaccines. The TRIVAC model was used to assess vaccine impact and cost-effectiveness. The model estimated health and economic outcomes attributed to 10 successive vaccinated birth cohorts (2013-2022) from a government and societal perspective. Epidemiological and economic data used in the model were based on national cost studies, and surveillance data, as well as estimates from the scientific literature. Cost-effectiveness was estimated for both the monovalent (RV1) and pentavalent vaccines (RV5). A multivariate scenario analysis (SA) was performed to evaluate the uncertainty around the incremental cost-effectiveness ratios (ICERs). With 3% discounting of costs and health benefits over the period 2013-2022, rotavirus vaccination in Albania could avert 51,172 outpatient visits, 14,200 hospitalizations, 27 deaths, 950 disability-adjusted life-years (DALYs), and gain 801 life-years. When both vaccines were compared to no vaccination, the discounted cost per DALY averted was US$ 2008 for RV1 and US$ 5047 for RV5 from a government perspective. From the societal perspective the values were US$ 517 and US$ 3556, respectively. From both the perspectives, the introduction of rotavirus vaccine to the Albanian immunization schedule is either cost-effective or highly cost-effective for a range of plausible scenarios. In most scenarios, including the base-case scenario, the discounted cost per DALY averted was less than three times the gross domestic product (GDP) per capita. However, rotavirus vaccination was not cost-effective when rotavirus cases

DETERMINANT OF HOUSING RENTS IN URBAN ALBANIA: AN EMPIRICAL HEDONIC PRICE APPLICATION WITH NSA SURVEY DATA

Directory of Open Access Journals (Sweden)

Mustafa Kahveci

2017-06-01

Full Text Available As an immobile, durable and heterogonous good, each housing unit has a bundle of different characteristics. Hedonic price method, which depends on the consumer theory of the classical economics, implies that each characteristic of heterogeneous goods provides a different level of satisfaction or utility to the consumer, being widely accepted as a toolkit for estimating effects of these characteristics on prices and rents. HPM expresses housing prices as the function of structural characteristics, location characteristics, and neighborhood characteristics. Theory and empirical applications of the HPM, which have been used for more than 40 years in developed countries, due to the lack of suitable data related literature is limited in Albania. The aim of this paper is to analyze the relationship between housing rents and housing characteristics in urban Albania with micro database of Living Conditions and Income Survey 2012.

Issues, impacts, and implications of shrimp aquaculture in Thailand

Science.gov (United States)

Dierberg, Forrest E.; Kiattisimkul, Woraphan

1996-09-01

Water quality impacts to and from intensive shrimp aquaculture in Thailand are substantial. Besides the surface and subsurface salinization of freshwaters, loadings of solids, oxygen-consuming organic matter, and nutrients to receiving waters are considerable when the cumulative impacts from water exchange during the growout cycle, pond drainage during harvesting, and illegal pond sediment disposal are taken into account. Although just beginning to be considered in Thailand, partial recirculating and integrated intensive farming systems are producing promising, if somewhat limited, results. By providing on-site treatment of the effluent from the shrimp growout ponds, there is less reliance on using outside water supplies, believed to be the source of the contamination. The explosion in the number of intensively operated shrimp farms has not only impacted the coastal zone of Thailand, but has also resulted in an unsustainable aquaculture industry. Abandonment of shrimp ponds due to either drastic, disease-caused collapses or more grandual, year-to-year reductions in the productivity of the pond is common. To move Thailand towards a more sustainable aquaculture industry and coastal zone environment, integrated aquaculture management is needed. Components of integrated aquaculture management are technical and institutional. The technical components involve deployment of wastewater treatment and minimal water-use systems aimed at making aquaculture operations more hydraulically closed. Before this is possible, technical and economic feasibility studies on enhanced nitrification systems and organic solids removal by oxidation between production cycles and/or the utilization of plastic pond liners need to be conducted. The integration of semi-intensive aquaculture within mangrove areas also should be investigated since mangrove losses attributable to shrimp aquaculture are estimated to be between 16 and 32% of the total mangrove area destroyed betweeen 1979 and 1993

2012-05-01

Full Text Available In Bangladesh, black tiger shrimp (Penaeus monodon; Fabricius, 1798 aquaculture has come to be one of the most important sectors in both the rural and national economies. Likewise, organic shrimp aquaculture has emerged as an alternative farming enterprise for farmers especially in the southwestern districts of Bangladesh. The present study aims to show key performance characteristics of organic shrimp farmers and farming in a prototypical shrimp farming area in Bangladesh. Data was collected in 2009 from organic shrimp farmers in the Kaligonj and Shyamnagar sub-districts through questionnaire interviews, transect walks and focus group discussions. The mean productivity of organic shrimp farming in the area is 320 kg ha⁻¹ yr⁻¹ (ranging from 120 to 711 kg ha⁻¹year⁻¹. Organic farmers are more likely to have a higher monthly income and less aquaculture experience. Moreover, suitable landholdings and classified labor distribution have been found to play an important role in the development of organic shrimp aquaculture. The most common assets of organic shrimp aquaculture are high yield, low production cost, available post larvae and high market prices. Small business farmers are likely to earn more income benefits from organic shrimp aquaculture than their larger-scale counterparts. Finally, the paper suggests that more research is needed to stimulate the success of organic shrimp aquaculture.

IMPACT OF THE TOURISM DEVELOPMENT ON POVERTY REDUCTION IN ALBANIA AS A COUNTRY IN TRANSITION

Directory of Open Access Journals (Sweden)

Evelina BAZINI

2008-06-01

Full Text Available Fighting poverty is a major challenge for Albania, in which tourism can make a significant contribution. However, it is important to analyze the basic concepts behind specific policies and actions that would allow tourism to be effective, like the possibilities offered by micro-credit. In fact, tourism development must be properly managed, avoiding anarchic, speculative development, so that it can be transformed into benefits for the local people and their environment. This paper will list seven areas of action through which tourism development in Albania as a Mediterranean country could fight poverty, with several of them relating to the possibilities created by micro-credit. After analyzing each of these approaches, a methodology must be drawn up for selecting the most effective projects from two points of view – interest for tourism and impact on poverty reduction.

Relational governance – an examination of the apple sector in Albania

Directory of Open Access Journals (Sweden)

Blendi GËRDOÇI

2015-06-01

Full Text Available This study provides an in-depth analysis of the value chain governance in the fruit sector in Albania. Particular attention was paid to the nature of relations between agricultural producers and marketing channel chosen by them, distinguishing between big wholesalers, local collectors and exporters, longer-term relations, commitment and trust, and contracting along the value chain. Given the absence of, or weak, contract enforcement and the clear evidence of embeddedness in dyadic relationships in this chain, we focused our analysis on sustained relationships, contracting and personal bonds as a determinant factor to improve business relationship quality. This paper is based on a structured survey targeting 182 orchard farmers in two leading fruit production regions in Albania, namely Korca and Peshkopia. The survey showed a weak prevalence of verbal contracts in embedded relationships. The percentage of contracts between farmers and local collectors is slightly higher compared to wholesalers. This evidence is much stronger when we investigate the incidence of contracts in stable relationships (i.e. selling to the same buyer. We also find that mature relationships generate higher sustainability - a result which does not come as a surprise, although the coordination between farmers and other actors downstream is only at early stages. The main implications which arise from our analysis are relevant for agribusinesses, farmers and policy makers.

Full Text Available Banks need to make thorough analysis and take into consideration all the potential risks that arise related to their lending, preventing bad loans mostly during economic slowdown. The Non-Performing Loans (now on referred as NPL in Kosovo continued falling from 8.7% as it was in 2013 to 8.3% in 2014. While in 2014 NPL level decreased, the provisioning for loans continued to increase from 110.5% to 114.4%. This is a positive toward any unexpected situation. Lost loans have continued to increase in moderated way for the last four years.  Banking Sector in Albania since the last economic recession entered into third period of development which shows huge problems with high NPL ratio, credit shrink, lower banks’ profitability and intensive attempts to introduce stabilizing mechanisms. NPL ratio was the highest in South East Europe Countries (now on referred as SEEC region, number of outstanding loans tended to decrease such as profit in banking sectors. As a response to highest NPL ratio compared to world level, Kosovo authority has set only guidelines for restructuring and monitoring the process of regularity.  This provides banks with a wide range of autonomy in the procedures of restructuring. Authority in Albania has been active in the process of normalizing the system. In 2013 has introduced the guideline on corporate loan restructuring. The guideline promotes 12 principles.

Molecular identification and artificial cultivation of a wild isolate of oyster mushroom in Albania

Full Text Available Basidiomata of a wild mushroom macroscopically recognised as Pleurotus ostreatus were observed on an oak trunk in a mixed wood of northern Albania. Pure cultures of the fungus were then obtained on potato-dextrose-agar medium. Molecular analyses of genomic DNA of the fungus confirmed its identification. The rDNA ITS region nucleotide sequence of the studied Pleurotacea matched at 99% those of two P. ostreatus strains already present in NCBI GenBank database. The rDNA ITS nucelotide sequences of two pure cultures of the Albanian P. ostreatus were deposited in EMBL database under the accession numbers LN849458 and LN849459. One of the fungus isolates was subsequently cultivated under protected and semi-natural conditions. Productivity and biological efficiency of the Albanian P. ostreatus ranged from about 10% to 16% and from 33 to 53.33%, respectively. This seems to be the first report on the artificial cultivation of P. ostreatus in Albania and could have, in the next future, a high economic impact on development and diffusion of this important edible mushroom over the country.

Nutrient discharge from China’s aquaculture industry and associated environmental impacts

Zhang, Ying; Bleeker, Albert; Liu, Junguo

2015-04-01

China’s aquaculture industry accounts for the largest share of the world’s fishery production, and provides a principal source of protein for the nation’s booming population. However, the environmental effects of the nutrient loadings produced by this industry have not been systematically studied or reviewed. Few quantitative estimates exist for nutrient discharge from aquaculture and the resultant nutrient enrichment in waters and sediments. In this paper, we evaluate nutrient discharge from aquacultural systems into aquatic ecosystems and the resulting nutrient enrichment of water and sediments, based on data from 330 cases in 51 peer-reviewed publications. Nitrogen use efficiency ranged from 11.7% to 27.7%, whereas phosphorus use efficiency ranged from 8.7% to 21.2%. In 2010, aquacultural nutrient discharges into Chinese aquatic ecosystems included 1044 Gg total nitrogen (184 Gg N from mariculture; 860 Gg N freshwater culture) and 173 Gg total phosphorus (22 Gg P from mariculture; 151 Gg P from freshwater culture). Water bodies and sediments showed high levels of nutrient enrichment, especially in closed pond systems. However, this does not mean that open aquacultural systems have smaller nutrient losses. Improvement of feed efficiency in cage systems and retention of nutrients in closed systems will therefore be necessary. Strategies to increase nutrient recycling, such as integrated multi-trophic aquaculture, and social measures, such as subsidies, should be increased in the future. We recommend the recycling of nutrients in water and sediments by hybrid agricultural-aquacultural systems and the adoption of nutrient use efficiency as an indicator at farm or regional level for the sustainable development of aquaculture; such indicators; together with water quality indicators, can be used to guide evaluations of technological, policy, and economic approaches to improve the sustainability of Chinese aquaculture.

Full Text Available Ecuador has a long tradition in aquaculture, mainly related to the cultivation of shrimp and tilapia in earthen ponds. Land-based production methods have a large environmental, economic and social impact due to the extensive use of land and its effects on the ecosystems. In order to increase the production of fish without further land use and with a lower environmental impact, a good alternative is the culture of fish in floating cages, adopting technologies used successfully in many other countries. This article analyses the current situation of offshore aquaculture (the production of fish and other aquatic organisms in the open sea in Ecuador, and the prospects for the future of this sector in the country.

Full Text Available Typically ‘income tax’ laws rely on financial accounting data to determine the taxable income of a business entity, although financial and tax accounting have different goals and requirements. The purpose of this paper is to explore the relationship between financial and tax accounting rules in Albania. The study employs a mixed methodology, comprising a review of the legislation, institutional framework and context, and semi-structured interviews with accountants, academics and institutional players. By reviewing the development of this relationship during the past 20 years, we aim to identify and explain the major divergences at present between two sets of rules.

Blaylock, Reginald B; Bullard, Stephen A

2014-12-01

Aquaculture is the fastest-growing segment of food production and is expected to supply a growing portion of animal protein for consumption by humans. Because industrial aquaculture developed only recently compared to industrial agriculture, its development occurred within the context of a growing environmental awareness and acknowledgment of environmental issues associated with industrial farming. As such, parasites and diseases have become central criticisms of commercial aquaculture. This focus on parasites and diseases, however, has created a nexus of opportunities for research that has facilitated considerable scientific advances in the fields of parasitology and aquaculture. This paper reviews Myxobolus cerebralis , Lepeophtheirus salmonis , white spot syndrome virus, and assorted flatworms as select marquee aquaculture pathogens, summarizes the status of the diseases caused by each and their impacts on aquaculture, and highlights some of the significant contributions these pathogens have made to the science of parasitology and aquaculture.

To analyze the initial experience of the nationwide clinical telemedicine program of Albania, as a model of implementation of telemedicine using "Initiate-Build-Operate-Transfer" strategy. This was a retrospective study of prospectively collected data from teleconsultations in Albania between January 1, 2014 and August 26, 2015, delivered synchronously, asynchronously, or a combination of both methods. Patient's demographics, mode of consultation, clinical specialty, hospitals providing referral and consultation, time from initial call to completion of consultation, and patient disposition following teleconsultation were analyzed. Challenges of the newly created program have been identified and analyzed as well. There were 1,065 teleconsultations performed altogether during the study period. Ninety-one patients with autism managed via telemedicine were not included in this analysis and will be reported separately. Of 974 teleconsults, the majority were for radiology, neurotrauma, and stroke (55%, 16%, and 10% respectively). Asynchronous technology accounted for nearly two-thirds of all teleconsultations (63.7%), followed by combined (24.3%), and then synchronous (12.0%). Of 974 cases, only 20.0% of patients in 2014 and 22.72% of patients in 2015 were transferred to a tertiary hospital. A majority (98.5%) of all teleconsultations were conducted within the country itself. The Integrated Telemedicine and e-Health program of Albania has become a useful tool to improve access to high-quality healthcare, particularly in high demanding specialty disciplines. A number of challenges were identified and these should serve as lessons for other countries in their quest to establish nationwide telemedicine programs.

Public attitudes towards marine aquaculture: A comparative analysis of Germany and Israel

We report on bi-national (Germany–Israel) research on relationships between public attitudes, behaviours and preferences related to marine aquaculture. Aquaculture's world-wide market share accounts for over half of all aquatic products. In many places, the sector's explosive growth has outstripped scientific knowledge and governance provisions. Small producers such as Israel and Germany seeking to expand domestic production must address environmental challenges posed by fish farming, stakeholder competition in crowded coastal zones and public/consumer receptiveness. Based on survey data obtained from both the countries, correlation analysis (Pearson's r-statistic) was used to test four hypotheses. Of these, one (positive relationship between coastal tourism and aquaculture attitudes) was supported in both countries. The hypothesis of positive relationships between lifestyle (environment/health) behaviours and aquaculture attitudes was supported only in Germany and the hypothesis of negative relationships between concern for the environment and aquaculture attitudes was supported only in Israel. These results are significant for policy, business, NGO and other stakeholders. Moreover, they point to the importance of this type of comparative research in improving our understanding of local factors influencing attitude-formation and inter-relationships. First, the tourism–aquaculture relationship found indicates potential synergies between two sectors reliant on the coastal zone that should be taken into account by planning authorities. The divergent environment–aquaculture results were especially interesting since in both countries, the primary concern regarding aquaculture expansion was environmental impacts. Closer inspection of the survey results revealed that this relationship may have been influenced by the orientation of environmental concerns in each population. Germans focus on depletion of wildstocks and Israelis on cage effluent and marine pollution

Optimizing Ocean Space: Co-siting Open Ocean Aquaculture

Cobb, B. L.; Wickliffe, L. C.; Morris, J. A., Jr.

2016-12-01

In January of 2016, NOAA's National Marine Fisheries Service released the Gulf Aquaculture Plan (GAP) to manage the development of environmentally sound and economically sustainable open ocean finfish aquaculture in the Gulf of Mexico (inside the U.S. Exclusive Economic Zone [EEZ]). The GAP provides the first regulatory framework for aquaculture in federal waters with estimated production of 64 million pounds of finfish, and an estimated economic impact of $264 million annually. The Gulf of Mexico is one of the most industrialized ocean basins in the world, with many existing ocean uses including oil and natural gas production, shipping and commerce, commercial fishing operations, and many protected areas to ensure conservation of valuable ecosystem resources and services. NOAA utilized spatial planning procedures and tools identifying suitable sites for establishing aquaculture through exclusion analyses using authoritative federal and state data housed in a centralized geodatabase. Through a highly collaborative, multi-agency effort a mock permitting exercise was conducted to illustrate the regulatory decision-making process for the Gulf. Further decision-making occurred through exploring co-siting opportunities with oil and natural gas platforms. Logistical co-siting was conducted to reduce overall operational costs by looking at distance to major port and commodity tonnage at each port. Importantly, the process of co-siting allows aquaculture to be coupled with other benefits, including the availability of previously established infrastructure and the reduction of environmental impacts.

Aquaculture is the fastest growing food sector and continues to expand alongside terrestrial crop and livestock production. Using portfolio theory as a conceptual framework, we explore how current interconnections between the aquaculture, crop, livestock, and fisheries sectors act as an impediment to, or an opportunity for, enhanced resilience in the global food system given increased resource scarcity and climate change. Aquaculture can potentially enhance resilience through improved resource use efficiencies and increased diversification of farmed species, locales of production, and feeding strategies. However, aquaculture’s reliance on terrestrial crops and wild fish for feeds, its dependence on freshwater and land for culture sites, and its broad array of environmental impacts diminishes its ability to add resilience. Feeds for livestock and farmed fish that are fed rely largely on the same crops, although the fraction destined for aquaculture is presently small (∼4%). As demand for high-value fed aquaculture products grows, competition for these crops will also rise, as will the demand for wild fish as feed inputs. Many of these crops and forage fish are also consumed directly by humans and provide essential nutrition for low-income households. Their rising use in aquafeeds has the potential to increase price levels and volatility, worsening food insecurity among the most vulnerable populations. Although the diversification of global food production systems that includes aquaculture offers promise for enhanced resilience, such promise will not be realized if government policies fail to provide adequate incentives for resource efficiency, equity, and environmental protection.

The growth of finfish in global open-ocean aquaculture under climate change.

Science.gov (United States)

Klinger, Dane H; Levin, Simon A; Watson, James R

2017-10-11

Aquaculture production is projected to expand from land-based operations to the open ocean as demand for seafood grows and competition increases for inputs to land-based aquaculture, such as freshwater and suitable land. In contrast to land-based production, open-ocean aquaculture is constrained by oceanographic factors, such as current speeds and seawater temperature, which are dynamic in time and space, and cannot easily be controlled. As such, the potential for offshore aquaculture to increase seafood production is tied to the physical state of the oceans. We employ a novel spatial model to estimate the potential of open-ocean finfish aquaculture globally, given physical, biological and technological constraints. Finfish growth potential for three common aquaculture species representing different thermal guilds-Atlantic salmon ( Salmo salar ), gilthead seabream ( Sparus aurata ) and cobia ( Rachycentron canadum )-is compared across species and regions and with climate change, based on outputs of a high-resolution global climate model. Globally, there are ample areas that are physically suitable for fish growth and potential expansion of the nascent aquaculture industry. The effects of climate change are heterogeneous across species and regions, but areas with existing aquaculture industries are likely to see increases in growth rates. In areas where climate change results in reduced growth rates, adaptation measures, such as selective breeding, can probably offset potential production losses. © 2017 The Author(s).

Full Text Available Introduction: Head injury (HI is a serious morbid state caused by structural changes of the scalp, skull, and/or its contents, due to mechanical forces. Generally, the most frequent cause of HI is road traffic accident (RTA, followed by homicidal and falling injuries. The aim of present study is to assess epidemiology data, causes and patterns responsible for HI among Albanian subjects. Methodology: All HI cases (1000 are collected by the Forensic Institute of Albania, based on medical and forensic records of traumatized subjects between 2007- 2012. The prospectively-collected and descriptive information is focused on demographic data, responsible factors, type and level of cranial and brain injury, as well as their outcome. Results: The majority of HI victims were male (84% of age range of 15yrs -35yrs (70%. RTA was the HI cause in 88%, followed by homicides (3.8%, falling (3% etc. With respect to injury mechanisms, extra-dural hematoma was found in 93% of cases, followed by cerebral edema (61%, cerebral contusion (37%, skull bone fractures (35%, etc. Severe alteration of the consciousness was observed in 57% of the cases, while amnesia lasted longer than 4 weeks in 44% of the subjects included in our study. Discussion: This survey demonstrates that the majority of HI victims' is young and middle age males target group exposed to RTA. The increase of vehicles' use in placecountry-regionAlbania is more evident than RTA-related HI, indicating that driving newer vehicles with safer technology or helmets use while motorcycling can potentially decline the fatal outcome.

Streptomyces bacteria as potential probiotics in aquaculture

Tan Loh eTeng Hern

2016-02-01

Full Text Available In response to the increased seafood demand from the ever-going human population, aquaculture has become the fastest growing animal food-producing sector. However, the indiscriminate use of antibiotics as a biological control agents for fish pathogens has led to the emergence of antibiotic resistance bacteria. Probiotics are defined as living microbial supplement that exert beneficial effects on hosts as well as improvement of environmental parameters. Probiotics have been proven to be effective in improving the growth, survival and health status of the aquatic livestock. This review aims to highlight the genus Streptomyces can be a good candidate for probiotics in aquaculture. Studies showed that the feed supplemented with Streptomyces could protect fish and shrimp from pathogens as well as increase the growth of the aquatic organisms. Furthermore, the limitations of Streptomyces as probiotics in aquaculture is also highlighted and solutions are discussed to these limitations.

Asia contributes more than 90% to the world's aquaculture production. Like other farming systems, aquaculture is plagued with disease problems resulting from its intensification and commercialization. This paper describes the various factors, providing specific examples, which have contributed to the current disease problems faced by what is now the fastest growing food-producing sector globally. These include increased globalization of trade and markets; the intensification of fish-farming practices through the movement of broodstock, postlarvae, fry and fingerlings; the introduction of new species for aquaculture development; the expansion of the ornamental fish trade; the enhancement of marine and coastal areas through the stocking of aquatic animals raised in hatcheries; the unanticipated interactions between cultured and wild populations of aquatic animals; poor or lack of effective biosecurity measures; slow awareness on emerging diseases; the misunderstanding and misuse of specific pathogen free (SPF) stocks; climate change; other human-mediated movements of aquaculture commodities. Data on the socio-economic impacts of aquatic animal diseases are also presented, including estimates of losses in production, direct and indirect income and employment, market access or share of investment, and consumer confidence; food availability; industry failures. Examples of costs of investment in aquatic animal health-related activities, including national strategies, research, surveillance, control and other health management programmes are also provided. Finally, the strategies currently being implemented in the Asian region to deal with transboundary diseases affecting the aquaculture sector are highlighted. These include compliance with international codes, and development and implementation of regional guidelines and national aquatic animal health strategies; new diagnostic and therapeutic techniques and new information technology; new biosecurity measures including

Full Text Available We employed mtDNA and nuclear SNPs to investigate the genetic diversity of sheep breeds of three countries of the Mediterranean basin: Albania, Greece, and Italy. In total, 154 unique mtDNA haplotypes were detected by means of D-loop sequence analysis. The major nucleotide diversity was observed in Albania. We identified haplogroups, A, B, and C in Albanian and Greek samples, while Italian individuals clustered in groups A and B. In general, the data show a pattern reflecting old migrations that occurred in postneolithic and historical times. PCA analysis on SNP data differentiated breeds with good correspondence to geographical locations. This could reflect geographical isolation, selection operated by local sheep farmers, and different flock management and breed admixture that occurred in the last centuries.

The vulnerability of Albanian population to natural disasters is due to poverty, inadequate infrastructures (e.g. communication network, basic public facilities and works of soil protection), an uncontrollable building boom and a range of environmental factors, both geomorphological and geological. The greatest disaster threats in Albania are those related to severe earthquakes and large-scale riverine floods. Geohazards assessment is a crucial point for Albania, which has been subject to a rapid development after the recent political changes, resulting in a general land degradation. Also the rate of migration from rural areas to the most urbanized areas currently represents a major problem for the National Civil Protection, since the urban sprawl in the suburbs are often located in high-risk areas, particularly vulnerable to natural hazards. The National Civil Protection system, in terms of subsidiary institutional and volunteer components, is relatively young in Albania. The progressive decentralization of the administrative competences triggered by the recent political changes is accompanied by the acquisition of new territorial information and the development of specific protocols for the emergency management, as well as the risk reduction. The management of natural disasters demands not only an early response to the criticalities, but also a correct mapping of the damage and the development of emergency plans for future events in order to protect lives, properties and the environment and moreover to spread the risk awareness in the population and to prepare it for such circumstances. The main purposes of the Pilot Project "Shkoder" is to enhance the resilience of a little community, located 9 kilometers south-west of Shkodra (Northern Albania), to flooding and earthquakes and to promote the subsidiarity principle by means of: a) demonstrating how basic information for the disaster planning (collected with a real demonstrative field survey) and the risk

Use of sunlight to degrade oxytetracycline in marine aquaculture's waters

International Nuclear Information System (INIS)

Leal, J.F.; Esteves, V.I.; Santos, E.B.H.

2016-01-01

Oxytracycline (OTC) is a broad spectrum antibiotic authorized for use in European aquaculture. Its photo-degradation has been widely studied in synthetic aqueous solutions, sometimes resorting to expensive methods and without proven effectiveness in natural waters. Thus, this work studied the possibility to apply the solar photo-degradation for removal of OTC from marine aquaculture's waters. For that, water samples were collected at different locals of the water treatment circuit, from two different aquaculture companies. Water samples were firstly characterized regarding to pH, salinity, total suspended solids (TSS), organic carbon and UV–Vis spectroscopic characteristics. Then, the samples were spiked with OTC and irradiated using simulated sunlight in order to evaluate the matrix effects on OTC photo-degradation. From kinetic results, the apparent quantum yields and the outdoor half-life times, at 40°N for midsummer and midwinter days were estimated by the first time for these conditions. For a midsummer day, at sea level, the outdoor half-life time predicted for OTC in these aquaculture's waters ranged between 21 and 25 min. Additionally, the pH and salinity effects on the OTC photo-degradation were evaluated and it has been shown that high pH values and the presence of sea salt increase the OTC photo-degradation rate in aquaculture's waters, compared to results in deionised water. The results are very promising to apply this low-cost methodology using the natural sunlight in aquaculture's waters to remove OTC. - Highlights: • Oxytetracycline (OTC) is one of the most used antibiotics in aquaculture. • OTC photolysis in marine aquaculture's water is faster than in deionised water. • The sunlight radiation quickly remove the OTC from aquaculture's water. • Outdoor half-life for a midsummer day is 21–25 min in aquaculture's water. • High pH's and salinities increase the OTC photo-degradation. - This work

Wage Tendency in Albania; The Reaction to the Global Economic and Financial Crisis

Directory of Open Access Journals (Sweden)

Imelda Sejdini

2011-01-01

Full Text Available Wage of both public and private sectors is a very important source of incomes for most of the population in Albania. The importance of public sector wage policy exceeds the sector's actual share of total employment, because the level of wages in this sector is, to a certain extent, a point of reference for wages in the private sector, too. During the first transition years the wages of a great number of the employees, whose enterprises had stopped being operational, were practically a form of social support. The data for this paper are gathered from all the surveys done on wages during transition from the public sources and the institute of statistics. From these data results that the wages have increased recurrently, first of all to counter the inflationary effects and to provide a better remuneration to the employees in both sector, despite the global financial crisis. This is due to the lack of full integration in the global markets. In this paper we discuss about the wage tendency in Albania as a country in further development, exposed to the risks of the global financial crisis, and the reaction to the difficulties encountered while the country is preparing for the EU integration.

The apparatus invented by Dr. Luigj Benusi in 1943, in Tirana, was a practical application of the Kowarsky technique and Ambard laws, helping in determining blood urea levels and very important to a variety of diseases, mainly kidney disorders. The apparatus was invented and prepared from very simple laboratory materials, such as glasses, test tubes, corks and volumetric cylinders. Technologically, it was based upon the determination of blood urea through hypobromite, and, among the advantages of the apparatus of Benusi, were its extreme simplicity, the smaller amount of blood needed for producing results (2 milliliters), as well as an easiest way to clean up and to manage the apparatus from a practical point of everyday use.

Marine Spatial Planning Makes Room for Offshore Aquaculture in a Crowded Coastal Zone

Science.gov (United States)

Stevens, J.

2016-12-01

Offshore aquaculture is an emerging industry predicted to contribute significantly to global seafood production and food security. However, aquaculture farms can generate conflicts by displacing existing ocean user groups and impacting ecosystems. Further, there are multiple farm types with different seafood species, productivity levels and impacts. Thus, it is important to strategically and simultaneously plan farm type and location in relation to the seascape in order to most effectively maximize aquaculture value while also minimizing conflicts and environmental impacts. We address this problem and demonstrate the value of multi-objective planning with a case study that integrates bioeconomic modeling with ecosystem service tradeoff analysis to inform the marine spatial planning (MSP) of mussel, finfish and kelp aquaculture farms in the already-crowded Southern California Bight (SCB) ecosystem. We considered four user groups predicted to conflict with or be impacted by the three types of aquaculture: wild-capture fisheries, ocean viewshed from coastal properties, marine benthic habitat protection, and risk of disease outbreak between farms. Results indicate that significant conflicts and impacts, expected under conventional planning, can be reduced by strategic planning. For example, 28% of potential mussel farm sites overlap with wild-capture halibut fishery grounds, yet MSP can enable mussel aquaculture to generate up to a third of its total potential industry value without impacting halibut fishery yield. Results also highlight hotspot areas in the SCB most appropriate for each type of aquaculture under MSP, as well as particular mussel, finfish and kelp aquaculture spatial plans that align with legislative regulations on allowable impacts from future aquaculture farms in California. This study comprehensively informs aquaculture farm design in the SCB, and demonstrates the value of multi-objective simultaneous planning as a key component in MSP.

The incidence of visceral leishmaniasis (VL) in Albania is higher than in other countries of southern Europe, however the role of local sand fly species in the transmission of Leishmania infantum was not addressed conclusively. In 2006, a country-wide collection of sand flies performed in 14 sites selected based on recent occurrence of VL cases showed that Phlebotomus neglectus was by far the most prevalent species (95.6%). Furthermore, 15% of pools made from 422 P. neglectus females tested positive for Leishmania sp. genomic DNA. In the same year, Culicoides trapping was performed for bluetongue disease surveillance in 91 sites of southern Albania, targeting livestock farms regardless recent occurrence of VL in the surveyed areas. In 35 sites where sand flies were collected along with midges, Phlebotomus perfiliewi was the most prevalent among the Phlebotomus species identified, however search for leishmanial DNA in females of this species was unsuccessful. In 2011, sand flies were trapped in 4 sites of north Albania characterized by high VL incidence, and females were dissected to search for Leishmania infections. Both P. neglectus and P. tobbi were collected at high densities. Two positive specimens were detected from a sample of 64 P. neglectus trapped in one site (3.1%). Parasites were successfully cultured from one specimen and characterized as belonging to Leishmania infantum zymodeme MON-1, the only zymodeme so far identified as the agent of human and canine leishmaniasis in the country. Altogether our studies indicate that P. neglectus is the main leishmaniasis vector in Albania.

Full Text Available Aquaculture, and shrimp aquaculture in particular, can have major social and environmental impacts. However, aquaculture remains an understudied area in commons research. Can aspects of commons theory be applied to solve problems of aquaculture? We examined three coastal community-based shrimp aquaculture operations in northwestern Sri Lanka using a case study approach. These shrimp farms were individually owned by small producers and managed under local-level rules designed by cooperatives (samithis. The common-pool resource of major interest was water for aquaculture ponds, obtained from an interconnected common water body. We evaluated the shrimp farming social-ecological system by using Ostrom’s design principles for collective action. Key elements of the system were: clearly defined boundaries; collaboratively designed crop calendar, bottom-up approach involving community associations, multi-level governance, and farmers-and-government collaborative structures. Together, these elements resolved the excludability and subtractability problems of commons by establishing boundary and membership rules and collective choice rules.

Remote Sensing Approach for Documenting the Conversion of Mangroves to Aquaculture

Peneva, E.

2007-12-01

The loss of mangrove forests to aquaculture, particularly shrimp farming, in coastal Thailand presents serious environmental and societal problems. Shrimp farming is one of the fastest growing aquaculture sectors in many parts of the world, as well as one of the most controversial. In spite of considerable work put into understanding the impacts of shrimp aquaculture, few studies provide detailed assessment of the issue through time. This research compares three change detection techniques (Object-based; Change Vector Analysis (CVA); and Integrated GIS and Remote Sensing) in order to assess the mangrove conversion caused by aquaculture development in Krabi Province, Thailand between 1989, 2001 and 2007 using Landsat TM data. All three methods provide valuable information though each has its own merits. Preliminary results show 40% loss of mangroves between 1989 and 2007, 25% of which is to aquaculture development, 10% to urban, and 5% to agricultural land. This study will help establish a methodology that will aid coastal communities in Southeast Asia in determining sustainable land use management approaches.

In 2013 in Albania was implemented a collection of disaster losses based on Desinventar. The DesInventar system consists in a methodology and software tool that lead to the systematic collection, documentation and analysis of loss data on disasters. The main sources of information about disasters used for the Albanian database were the Albanian Ministry of Internal Affairs, the National Library and the State archive. Specifically for floods the database created contains nearly 900 datasets, for a period of 148 years (from 1865 to 2013). The data are georeferenced on the administrative units of Albania: Region, Provinces and Municipalities. The datasets describe the events by reporting the date of occurrence, the duration, the localization in administrative units and the cause. Additional information regards the effects and damage that the event caused on people (deaths, injured, missing, affected, relocated, evacuated, victims) and on houses (houses damaged or destroyed). Other quantitative indicators are the losses in local currency or US dollars, the damage on roads, the crops affected , the lost cattle and the involvement of social elements over the territory such as education and health centers. Qualitative indicators simply register the sectors (e.g. transportations, communications, relief, agriculture, water supply, sewerage, power and energy, industries, education, health sector, other sectors) that were affected. Through the queries and analysis of the data collected it was possible to identify the most affected areas, the economic loss, the damage in agriculture, the houses and people affected and many other variables. The most vulnerable Regions for the past floods in Albania were studied and individuated, as well as the rivers that cause more damage in the country. Other analysis help to estimate the damage and losses during the main flood events of the recent years, occurred in 2010 and 2011, and to recognize the most affected sectors. The database was

Public Perceptions of Aquaculture: Evaluating Spatiotemporal Patterns of Sentiment around the World.

Halley E Froehlich

Full Text Available Aquaculture is developing rapidly at a global scale and sustainable practices are an essential part of meeting the protein requirements of the ballooning human population. Locating aquaculture offshore is one strategy that may help address some issues related to nearshore development. However, offshore production is nascent and distinctions between the types of aquatic farming may not be fully understood by the public-important for collaboration, research, and development. Here we evaluate and report, to our knowledge, the first multinational quantification of the relative sentiments and opinions of the public around distinct forms of aquaculture. Using thousands of newspaper headlines (Ntotal = 1,596 from developed (no. countries = 26 and developing (42 nations, ranging over periods of 1984 to 2015, we found an expanding positive trend of general 'aquaculture' coverage, while 'marine' and 'offshore' appeared more negative. Overall, developing regions published proportionally more positive than negative headlines than developed countries. As case studies, government collected public comments (Ntotal = 1,585 from the United States of America (USA and New Zealand mirrored the media sentiments; offshore perception being particularly negative in the USA. We also found public sentiment may be influenced by local environmental disasters not directly related to aquaculture (e.g., oil spills. Both countries voiced concern over environmental impacts, but the concerns tended to be more generalized, rather than targeted issues. Two factors that could be inhibiting informed discussion and decisions about offshore aquaculture are lack of applicable knowledge and actual local development issues. Better communication and investigation of the real versus perceived impacts of aquaculture could aid in clarifying the debate about aquaculture, and help support future sustainable growth.

Probiotics as Antiviral Agents in Shrimp Aquaculture

Directory of Open Access Journals (Sweden)

Bestha Lakshmi

2013-01-01

Full Text Available Shrimp farming is an aquaculture business for the cultivation of marine shrimps or prawns for human consumption and is now considered as a major economic and food production sector as it is an increasingly important source of protein available for human consumption. Intensification of shrimp farming had led to the development of a number of diseases, which resulted in the excessive use of antimicrobial agents, which is finally responsible for many adverse effects. Currently, probiotics are chosen as the best alternatives to these antimicrobial agents and they act as natural immune enhancers, which provoke the disease resistance in shrimp farm. Viral diseases stand as the major constraint causing an enormous loss in the production in shrimp farms. Probiotics besides being beneficial bacteria also possess antiviral activity. Exploitation of these probiotics in treatment and prevention of viral diseases in shrimp aquaculture is a novel and efficient method. This review discusses the benefits of probiotics and their criteria for selection in shrimp aquaculture and their role in immune power enhancement towards viral diseases.

Full Text Available Foreign direct investment (FDI has been viewed as a power affecting economic growth (EG directly and indirectly during the past few decades. Foreign direct investment (FDI in developing countries brings economic development and enhances the international competitiveness of domestic enterprises. It is argued in the existing literature that foreign direct investment (FDI influences economic growth through technology diffusion, human capital formation, etc. FDI accounts for the largest and most important proportion of foreign capital in Albania, which undoubtedly plays an important role in the Albania’s economic development growth. However, as the country’s FDI increases, and in this paper I want to make an empirical research how the FDI has influenced the economic growth of the country. The findings revealed that there is a strong positive relationship between the FDI inflows and the GDP for the studied period which covers 1995 to 2012, thus a positive effect on the economic growth.

Bream pond aquaculture plays a very important role in China's aquaculture industry and is the main source of aquatic products. To regulate and control pond water quality and sediment, a movable solar pond aquaculture water quality regulation machine (SMWM) was designed and used. This machine is solar-powered and moves on water, and its primary components are a solar power supply device, a sediment lifting device, a mechanism for walking on the water's surface and a control system. The solar power supply device provides power for the machine, and the water walking mechanism drives the machine's motion on the water. The sediment lifting device orbits the main section of the machine and affects a large area of the pond. Tests of the machine's mechanical properties revealed that the minimum illumination necessary for the SMWM to function is 13,000 Lx and that its stable speed on the water is 0.02-0.03 m/s. For an illumination of 13,000-52,500 Lx, the sediment lifting device runs at 0.13-0.35 m/s, and its water delivery capacity is 110-208 m(3)/h. The sediment lifting device is able to fold away, and the angle of the suction chamber can be adjusted, making the machine work well in ponds at different water depths from 0.5 m to 2 m. The optimal distance from the sediment lifting device to the bottom of the pond is 10-15 cm. In addition, adjusting the length of the connecting rod and the direction of the traction rope allows the SMWM to work in a pond water area greater than 80%. The analysis of water quality in Wuchang bream (Parabramis pekinensis) and silver carp (Hypophthalmichthys molitrix) culture ponds using the SMWM resulted in decreased NH3(+)-N and available phosphorus concentrations and increased TP concentrations. The TN content and the amount of available phosphorus in the sediment were reduced. In addition, the fish production showed that the SMWM enhanced the yields of Wuchang bream and silver carp by more than 30% and 24%, respectively. These results

Without regular maintenance, roads can rapidly fall into disrepair, preventing realization of the longer term impacts of road improvements on development, such as increased agricultural production and growth in school enrollment, which is of particular importance for a network of local (access) roads. Inadequate local roads maintenance in Albania is proposed to be solved by implementing performance based maintenance approach for which the costing exercise is presented within the paper.

Aquacultures are of great economic importance worldwide but pollute pristine headwater streams, lakes, and estuaries. However, there are no in-depth studies of the consequences of aquacultures on dissolved organic matter (DOM) composition and structure. We performed a detailed molecular level characterization of aquaculture DOM quality and its bacterial degradation using four salmon aquacultures in Chile. Fluorescence measurements, ultrahigh-resolution mass spectrometry, and nuclear magnetic resonance spectroscopy of the DOM revealed specific and extensive molecular alterations caused by aquacultures. Aquacultures released large quantities of readily bioavailable metabolites (primarily carbohydrates and peptides/proteins, and lipids), causing the organic matter downstream of all the investigated aquacultures to deviate strongly from the highly processed, polydisperse and molecularly heterogeneous DOM found in pristine rivers. However, the upstream individual catchment DOM signatures remained distinguishable at the downstream sites. The benthic algal biovolume decreased and the bacterial biovolume and production increased downstream of the aquacultures, shifting stream ecosystems to a more heterotrophic state and thus impairing the ecosystem health. The bacterial DOM degradation rates explain the attenuation of aquaculture DOM within the subsequent stream reaches. This knowledge may aid the development of improved waste processing facilities and may help to define emission thresholds to protect sensitive stream ecosystems.

The complexity of heritage and societal development - The example of Gjirokastra, Albania

Directory of Open Access Journals (Sweden)

Bosse Lagerqvist

2015-11-01

Full Text Available Albania is formerly the most closed country in Europe and has suffered from severe economic and political problems during the last two decades. In the southern part lies Gjirokastra, birthplace of former dictator Enver Hoxha, and home to diverse communities of Albanians and Greeks. Gjirokastra Old Town, proclaimed Museum City by the regime in 1961 and later turned into a UNESCO World Heritage City, climbs the steep western side of the Drinos valley. During the communist era the city was heavily industrialized with a metal work factory as well as factories for products such as shoes, refrigerators, and umbrellas. On the eastern side is the archaeological site of the ancient city of Antigonea, thus defining a landscape with long historical processes and a multitude of narratives and interpretations. In recent years this landscape has witnessed increased efforts to secure what are perceived heritage values, focusing on the older structures i.e. the world heritage part of the city and the archaeological site. However, the structures of post-war era of Albania contribute significantly to the full context of the landscape, but since the mid-1990s and the collapse of Albanian post-communist economy the former industrial sites are increasingly deteriorating. Parallel with severe economic problems with massive volumes of unemployed, a criminally based economy on drug trafficking is increasing. This paper will discuss the societally based problems in securing different heritage assets for a positive societal development.

Evolution of Integrated Open Aquaculture Systems in Hungary: Results from a Case Study

Directory of Open Access Journals (Sweden)

József Popp

2018-01-01

Full Text Available This article presents the history of integrated farming in aquaculture through a Hungarian case study. The development of Hungarian integrated aquaculture is aligned with global trends. In the previous millennium, the utilization of the nutrients introduced into the system was the main aspect of the integration. In Hungary, technologies that integrated fish production with growing crops and animal husbandry appeared, including for example: large-scale fish-cum-rice production; fish-cum-duck production; and integrated pig-fish farming which were introduced in the second half of the 20th century. Today, the emphasis is on integrating the use of the kind of feed where the main goal is to minimize nutrient loads in the surrounding natural ecosystems and to maximize the utilization of the unit’s water resources. The various modern integrated freshwater aquaculture systems, such as intensive fish production combined with wetland, recirculation aquaculture system and multi-functional aquaculture, have proved their viability. However, the future opportunities for these systems have not always been properly recognized and acknowledged when the future of European aquaculture is discussed.

Regulatory Framework and Current Practices of the Radioactive Material Safe and Secure Transport in Albania

International Nuclear Information System (INIS)

Dollani, K.; Grillo, B.; Telhaj, E.

2016-01-01

Attempts for the establishing of a safe and secure radioactive material transport in Albania began a decade ago with formulation of the different regulation in the field of safe and secure handling of the radioactive materials. In 2004 a special regulation for the safe transport of radioactive material was prepared and approved by the National Radiation Protection Commission). This regulation has been based in the IAEA standards for the radioactive material transport and was reviewed periodically. The last regulation of the radioactive material transport was approved by Albanian government through a governmental ordinance. The transport of the radioactive material in Albania is performed by licensed subjects, which fulfill all requirements of the mentioned governmental ordinance. Based in the existing regulation, for each transport of radioactive material, a special permission is issued by NRPC. The issuing of permission allows competent authority to provide necessary information on transport regularity and to have under survey all transports of the radioactive material carried out inside the country. Last year were issued more than 80 permissions for the transport of the different types and categories of the radioactive sources. (author)

The impact and control of biofouling in marine aquaculture: a review.

Science.gov (United States)

Fitridge, Isla; Dempster, Tim; Guenther, Jana; de Nys, Rocky

2012-01-01

Biofouling in marine aquaculture is a specific problem where both the target culture species and/or infrastructure are exposed to a diverse array of fouling organisms, with significant production impacts. In shellfish aquaculture the key impact is the direct fouling of stock causing physical damage, mechanical interference, biological competition and environmental modification, while infrastructure is also impacted. In contrast, the key impact in finfish aquaculture is the fouling of infrastructure which restricts water exchange, increases disease risk and causes deformation of cages and structures. Consequently, the economic costs associated with biofouling control are substantial. Conservative estimates are consistently between 5-10% of production costs (equivalent to US$ 1.5 to 3 billion yr(-1)), illustrating the need for effective mitigation methods and technologies. The control of biofouling in aquaculture is achieved through the avoidance of natural recruitment, physical removal and the use of antifoulants. However, the continued rise and expansion of the aquaculture industry and the increasingly stringent legislation for biocides in food production necessitates the development of innovative antifouling strategies. These must meet environmental, societal, and economic benchmarks while effectively preventing the settlement and growth of resilient multi-species consortia of biofouling organisms.

Judicial cooperation in criminal matters comes as an old tradition, with different stages of development and dictated by political and historical conditions in which every country has passed. In the case of Albania, seen in a historical context, since the birth of the Albanian state and during the existence of the communist regime (1944-1990, judicial cooperation in criminal matters in general, and the implementation of extradition, in particular refers to only bilateral treaties between different countries, which were a clear expression of political alliances of the time. With the democratic changes occurring in the early 90s, along with the establishment of relations with many countries of Europe and the world, judicial cooperation in criminal matters was given an important role in setting the bases in the legislative framework and this led to the signing of the European Convention “On Extradition” (and its Protocols which its ratification by the Republic of Albania, which has become part of the domestic Albanian legislation, establishing a set of binding standards, which have already been applicable to the Albanian legislation.

McPeek, Kathleen C.; McDonald, P. Sean; VanBlaricom, Glenn

2015-01-01

Aquaculture operations are a frequent and prominent cause of anthropogenic disturbance to marine and estuarine communities and may alter species composition and abundance. However, little is known about how such disturbances affect trophic linkages or ecosystem functions. In Puget Sound, Washington, aquaculture of the Pacific geoduck clam (Panopea generosa) is increasing and involves placing nets and polyvinyl chloride (PVC) tubes in intertidal areas to protect juvenile geoducks from predators. Initial studies of the structured phase of the farming cycle have documented limited impacts on the abundance of some species. To examine the effect of geoduck aquaculture on ecological linkages, the trophic relationships of a local ubiquitous consumer, Pacific staghorn sculpin (Leptocottus armatus), to its invertebrate prey were compared between geoduck aquaculture sites and nearby reference areas with no aquaculture. Mark-recapture data indicated that sculpin exhibit local site fidelity to cultured and reference areas. The stomach contents of sculpin and stable isotope signatures of sculpin and their prey were examined to study the trophic ecology of cultured and reference areas. Results showed that the structured phase of geoduck aquaculture initiated some changes to staghorn sculpin ecology, as reflected in sculpin diet through stomach content analysis. However, carbon and nitrogen stable isotopes revealed that the general food web function of sculpin remained unchanged. The source of carbon at the base of the food web and the trophic position of sculpin were not impacted by geoduck aquaculture. The study has important implications for geoduck aquaculture management and will inform regulatory decisions related to shellfish aquaculture policy.

von Ahnen, Mathis; Pedersen, Per Bovbjerg; Hoffmann, Carl Christian

2016-01-01

Nitrate is typically removed from aquaculture effluents using heterotrophic denitrification reactors. Heterotrophic denitrification reactors, however, require a constant input of readily available organic carbon (C) sources which limits their application in many aquaculture systems for practical...... and/or economic reasons.A potential alternative technology for removing nitrate currently applied for treating surface and drainage water is based on using wood by-products as a carbon source for denitrification. Using lab-scale horizontal-flow woodchip filters, the current study investigated...... the potential of optimizing woodchip reactors for treating aquaculture effluent.

2017-05-01

fear of falling (FOF) is a major health concern among community-dwelling older adults that could restrict mobility. to examine the association of FOF with life-space mobility (i.e. the spatial area a person moves through in daily life) of community-dwelling older adults from five diverse sites. in total, 1,841 older adults (65-74 years) were recruited from Kingston, Canada; Saint-Hyacinthe, Canada; Tirana, Albania; Manizales, Colombia and Natal, Brazil. FOF was assessed using the Fall Efficacy Scale-International (FES-I total score), and the life space was quantified using the Life-Space Assessment (LSA), a scale that runs from 0 (minimum life space) to 120 (maximum life space). the overall average LSA total score was 68.7 (SD: 21.2). Multiple-linear regression analysis demonstrated a significant relationship of FOF with life-space mobility, even after adjusting for functional, clinical and sociodemographic confounders (B = -0.15, 95% confidence interval (CI) -0.26 to -0.04). The FOF × site interaction term was significant with a stronger linear relationship found in the Canadian sites and Tirana compared with the South American sites. After adjusting for all confounders, the association between FOF with LSA remained significant at Kingston (B = -0.32, 95% CI -0.62 to -0.01), Saint-Hyacinthe (B = -0.81, 95% CI -1.31 to -0.32) and Tirana (B = -0.57, 95% CI -0.89 to -0.24). FOF is an important psychological factor that is associated with reduction in life space of older adults in different social and cultural contexts, and the strength of this association is site specific. Addressing FOF among older adults would help improve their mobility in local communities, which in turn would improve social participation and health-related quality of life. © The Author 2017.

Development of a seaweed species-selection index for successful culture in a seaweed-based integrated aquaculture system

Science.gov (United States)

Kang, Yun Hee; Hwang, Jae Ran; Chung, Ik Kyo; Park, Sang Rul

2013-03-01

Integrated multi-trophic aquaculture (IMTA) has been proposed as a concept that combines the cultivation of fed aquaculture species ( e.g., finfish/shrimp) with extractive aquaculture species ( e.g., shellfish/seaweed). In seaweed-based integrated aquaculture, seaweeds have the capacity to reduce the environmental impact of nitrogen-rich effluents on coastal ecosystems. Thus, selection of optimal species for such aquaculture is of great importance. The present study aimed to develop a seaweed species-selection index for selecting suitable species in seaweed-based integrated aquaculture system. The index was synthesized using available literature-based information, reference data, and physiological seaweed experiments to identify and prioritize the desired species. Undaria pinnatifida, Porphyra yezoensis and Ulva compressa scored the highest according to a seaweed-based integrated aquaculture suitability index (SASI). Seaweed species with the highest scores were adjudged to fit the integrated aquaculture systems. Despite the application of this model limited by local aquaculture environment, it is considered to be a useful tool for selecting seaweed species in IMTA.

2013-01-01

A series of 31 Roman glasses dated to the 1st–4th c. AD from the present Albania was analyzed by the combined PIXE–PIGE method. The analysis shows typical natron-based glass of the Roman period, though statistical treatment using principal component analysis and bivariate plots reveals four distinct groups, which are qualified by increased levels of potassium, magnesium and titanium–manganese–iron oxides, respectively. MgO content may exceed 2% and reach the level commonly accepted for halophytic plant-ash glass. The groups are formed on account of mineral impurities in the sand, which gives support to the thesis of multiple production centers of raw glass in the imperial age

Disease in marine aquaculture

Science.gov (United States)

Sindermann, C. J.

1984-03-01

It has become almost a truism that success in intensive production of animals must be based in part on development of methods for disease diagnosis and control. Excellent progress has been made in methods of diagnosis for major pathogens of cultivated fish, crustacean and molluscan species. In many instances these have proved to be facultative pathogens, able to exert severe effects in populations of animals under other stresses (marginal physical or chemical conditions; overcrowding). The concept of stress management as a critical prophylactic measure is not new, but its significance is being demonstrated repeatedly. The particular relationship of water quality and facultative pathogens such as Vibrio, Pseudomonas and Aeromonas species has been especially apparent. Virus diseases of marine vertebrates and invertebrates — little known two decades ago — are now recognized to be of significance to aquaculture. Virus infections of oysters, clams, shrimps and crabs have been described, and mortalities have been attributed to them. Several virus diseases of fish have also been recognized as potential or actual problems in culture. In some instances, the pathogens seem to be latent in natural populations, and may be provoked into patency by stresses of artificial environments. One of the most promising approaches to disease prophylaxis is through immunization. Fish respond well to various vaccination procedures, and new non-stressing methods have been developed. Vibriosis — probably the most severe disease of ocean-reared salmon — has been controlled to a great extent through use of a polyvalent bacterin, which can be modified as new pathogenic strains are isolated. Prophylactic immunization for other bacterial diseases of cultivated fish has been attempted, especially in Japan, with some success. There is also some evidence that the larger crustaceans may be immunologically responsive, and that at least short-term protection may be afforded to cultured

Potential use of power plant reject heat in commercial aquaculture

Energy Technology Data Exchange (ETDEWEB)

Olszewski, M.

1977-01-01

Current research and commercial activities in aquaculture operations have been reviewed. An aquaculture system using mostly herbivorous species in pond culture is proposed as a means of using waste heat to produce reasonably priced protein. The system uses waste water streams, such as secondary sewage effluent, animal wastes, or some industrial waste streams as a primary nutrient source to grow algae, which is fed to fish and clams. Crayfish feed on the clam wastes thereby providing a clean effluent from the aquaculture system. Alternate fish associations are presented and it appears that a carp or tilapia association is desirable. An aquaculture system capable of rejecting all the waste heat from a 1000-MW(e) power station in winter can accommodate about half the summer heat rejection load. The aquaculture facility would require approximately 133 ha and would produce 4.1 x 10/sup 5/ kg/year of fish, 1.5 x 10/sup 6/ kg/year of clam meat, and 1.5 x 10/sup 4/ kg/year of live crayfish. The estimated annual pretax profit from this operation is one million dollars. Several possible problem areas have been identified. However, technical solutions appear to be readily available to solve these problems. The proposed system shows considerable economic promise. Small scale experiments have demonstrated the technical feasibility of various components of the system. It therefore appears that a pilot scale experimental facility should be operated.

From aquaculture goals to real social and ecological impacts: carp introduction in rural Central Mexico.

Science.gov (United States)

Tapia, Mónica; Zambrano, Luis

2003-06-01

Aquaculture has been seen as a solution to food/protein availability in rural populations of poor countries. It is mainly based on exotic species, that produce changes in host system dynamics once introduced. Aquaculture not only changes the ecology of freshwater systems, but can also lead to modification of social relations. Until now, aquaculture programs have not been adequately analyzed no questioned enough. We evaluate both ecological effects and local social benefits of common carp aquaculture programs in shallow ponds of rural areas, using a municipality in Central Mexico as a case study. Using an "environmental entitlements" approach, our findings suggest that: i) carp aquaculture increases water turbidity and depletes native species reducing the poor people's access to them; ii) aquaculture mainly benefits pond owners rather than poor peasants. This mainly results from changes in fishing rights. We conclude that aquaculture policy goals and assumptions of benefits should be reviewed, if the negative ecological effects are to be decreased and conditions for people in rural areas are to be improved.

Full Text Available The potential use of mangrove swamp for fish farming industry is not clearly known. Therefore, current study was conducted to assess the growth performance of the Asian Seabass, Lates calcarifer cultivated in integrated mangrove-aquaculture system (IMAS and open aquaculture system without mangroves (OAS. Fish survival and biomass production were higher by 11% and 12.5% respectively in the IMAS than those in the OAS. The fish growth performance was higher in monsoon than that in other seasons. It was in association with water quality parameters such as, high levels of DO, chlorophylls-a,b, nitrate-N, DOC, TOC; low levels of light intensity, temperature (air, water, SPM, chlorophyll-c, nitrite-N, ammonia, total phosphate, reactive silicate, and POC; as well with moderate salinity. The water quality seemed to be favourable for growth and survival of the fish. Therefore, integrating the mangroves with fish farming of the Asian seabass is beneficial for better fish survival and biomass production.

Implications of Extracellular Polymeric Substance Matrices of Microbial Habitats Associated with Coastal Aquaculture Systems

Directory of Open Access Journals (Sweden)

Juan Carlos Camacho-Chab

2016-08-01

Full Text Available Coastal zones support fisheries that provide food for humans and feed for animals. The decline of fisheries worldwide has fostered the development of aquaculture. Recent research has shown that extracellular polymeric substances (EPS synthesized by microorganisms contribute to sustainable aquaculture production, providing feed to the cultured species, removing waste and contributing to the hygiene of closed systems. As ubiquitous components of coastal microbial habitats at the air–seawater and seawater–sediment interfaces as well as of biofilms and microbial aggregates, EPS mediate deleterious processes that affect the performance and productivity of aquaculture facilities, including biofouling of marine cages, bioaccumulation and transport of pollutants. These biomolecules may also contribute to the persistence of harmful algal blooms (HABs and their impact on cultured species. EPS may also exert a positive influence on aquaculture activity by enhancing the settling of aquaculturally valuable larvae and treating wastes in bioflocculation processes. EPS display properties that may have biotechnological applications in the aquaculture industry as antiviral agents and immunostimulants and as a novel source of antifouling bioproducts.

Large-scale climatic effects on traditional Hawaiian fishpond aquaculture.

Directory of Open Access Journals (Sweden)

Daniel McCoy

Full Text Available Aquaculture accounts for almost one-half of global fish consumption. Understanding the regional impact of climate fluctuations on aquaculture production thus is critical for the sustainability of this crucial food resource. The objective of this work was to understand the role of climate fluctuations and climate change in subtropical coastal estuarine environments within the context of aquaculture practices in He'eia Fishpond, O'ahu Island, Hawai'i. To the best of our knowledge, this was the first study of climate effects on traditional aquaculture systems in the Hawaiian Islands. Data from adjacent weather stations were analyzed together with in situ water quality instrument deployments spanning a 12-year period (November 2004 -November 2016. We found correlations between two periods with extremely high fish mortality at He'eia Fishpond (May and October 2009 and slackening trade winds in the week preceding each mortality event, as well as surface water temperatures elevated 2-3°C higher than the background periods (March-December 2009. We posit that the lack of trade wind-driven surface water mixing enhanced surface heating and stratification of the water column, leading to hypoxic conditions and stress on fish populations, which had limited ability to move within net pen enclosures. Elevated water temperature and interruption of trade winds previously have been linked to the onset of El Niño in Hawai'i. Our results provide empirical evidence regarding El Niño effects on the coastal ocean, which can inform resource management efforts about potential impact of climate variation on aquaculture production. Finally, we provide recommendations for reducing the impact of warming events on fishponds, as these events are predicted to increase in magnitude and frequency as a consequence of global warming.

Economic impact studies on development project of New Yogyakarta International Airport to aquaculture in Kulonprogo Coastal

Rachman, F.; Satriagasa, M. C.; Riasasi, W.

2018-03-01

New Yogyakarta International Airport (NYIA) is being constructed in Temon Sub District, Kulonprogo District. It lies on 587.2 ha area in the southern part of Java Island coastal area. Many areas of Kulonprogro coastal area are used for aquaculture of vanname shrimp. In that case, the aquaculture land needs to be cleared for the airport construction necessity and requires compensation. The value of the compensation needs to be right calculated by both sides, regarding the aquaculture land are local community assets. This study uses spatial analysis and visual interpretation. Whereas, the calculation of the acquisition value and income capital value uses Discounted Cash Flow (DCF) method. The result shows the area of aquaculture land which impacted to be cleared is 83 ha, means decreasing of shrimp ponds area in Temon Sub District, Kulonprogo District. The calculation of acquisition value for airport development indicates higher value than the income from the aquaculture activity. The results mean the aquaculture landlords do not incur losses due to the airport development project. These findings can be used for local government and related stakeholders to formulate a policy of aquaculture relocation and to estimate projection for aquaculture land suitability in Yogyakarta coastal area.

Background: Global aquaculture production has increased continuously over the last five decades, and particularly in China. Its aquaculture has become the fastest growing and most efficient agri-sector, with production accounting for more than 70% of the world’s aquaculture output. In the new century, with serious challenges regarding population, resources and the environment, China has been working to develop high-quality, effective, healthy, and sustainable blue agriculture through the application of modern biotechnology. Sound knowledge related to the biology and ecology of aquatic organisms has laid a solid foundation and provided the innovation and technology for rapid development of the aquaculture industry. Marine biotechnology, which is enabling solutions for ocean productivity and sustainability, has been promoted since the last decades of the 20th Century in China. Objective: In this article, priority areas of research, mainly genetic breeding, omics studies, novel production systems, biosecurity, bioprocesses and biorefinery, as well as the major progress of marine biotechnology R&D in China are reviewed. Conclusion: Current innovative achievements in China are not enough and the level and frequency of academic advancements must be improved. International cooperation and assistance remain crucial for the success of marine biotechnology. PMID:28553577

FEMINISATION OF POVERTY AND THE BURDEN OF THE OLDER WOMAN: BALANCING WORK AND FAMILY IN PRE-RETIREMENT LIFE AND THE ACCUMULATED DISADVANTAGE FOR OLDER WOMEN IN ALBANIA

Full Text Available The number one goal of the United Nations on the millennium development agenda is the eradication of extreme poverty and hunger. But poverty, as other problems, reveals more when examined from a multi-dimensional and dynamic perspective, and gender-sensitive lenses can make a major contribution. The “feminisation of poverty” (ranging from a higher incidence of women among the poor to poverty in terms of a lack of or limited choices has been documented by research throughout the world as a result of the interaction of three main factors: the introduction of gender elements in the research and literature on poverty; the high incidence of specific groups of women under the poverty line; and the mismatch between women’s life cycles and policies in place. This paper provides additional evidence on the “feminisation of poverty” by looking at the case of Albania as representative of an under-researched category of countries emerging as new democracies in the 1990s. The argument put forward is that the intersectionality of gender and age results in a larger burden of poverty among older women. To support the argument, the paper goes beyond the limited official poverty statistics in Albania by looking at the economic activity of women and men, analysing the work-family reconciliation policy framework in Albania, and providing evidence of the work-family tension based on secondary data analysis. It is found that combining work and family life in the pre-retirement period in Albania presents more disadvantages for women than for men, leading to the  “feminisation of poverty” in the post-retirement stages in life. This is then fuelling a new trend for unemployed women and retired women to work as informal caregivers, filling the deficiency in care for the eldest and youngest people in their own families or in the families of wealthier women. The policy logic and respective provisions in Albania, at best, are not discouraging the phenomenon.

Dabrowski, T.; Lyons, K.; Cusack, C.; Casal, G.; Berry, A.; Nolan, G. D.

2016-01-01

The Marine Institute, Ireland, runs a suite of operational regional and coastal ocean models. Recent developments include several tailored products that focus on the key needs of the Irish aquaculture sector. In this article, an overview of the products and services derived from the models are presented. The authors give an overview of a shellfish model developed in-house and that was designed to predict the growth, the physiological interactions with the ecosystem, and the level of coliform contamination of the blue mussel. As such, this model is applicable in studies on the carrying capacity of embayments, assessment of the impacts of pollution on aquaculture grounds, and the determination of shellfish water classes. Further services include the assimilation of the model-predicted shelf water movement into a new harmful algal bloom alert system used to inform end users of potential toxic shellfish events and high biomass blooms that include fish-killing species. Models are also used to identify potential sites for offshore aquaculture, to inform studies of potential cross-contamination in farms from the dispersal of planktonic sea lice larvae and other pathogens that can infect finfish, and to provide modelled products that underpin the assessment and advisory services on the sustainable exploitation of the resources of marine fisheries. This paper demonstrates that ocean models can provide an invaluable contribution to the sustainable blue growth of aquaculture and fisheries.

This report contains a review of the Agency's technical co-operation activities in Albania carried out during 1984-1994. In terms of coverage and analytical depth, country programmes summaries stand somewhere midway between in-depth country programme evaluations and individual project evaluations. They attempt to provide a comprehensive, descriptive picture of the Agency's co-operation with a Member State in a manner that will be particularly useful for programming decisions. The attempt is very much to describe - largely through statistical data - not to provide independent analysis and evaluation

2014-03-01

Full Text Available In this paper we explore factors potentially affecting the size of Albanian insurance market, over the period 1999 to 2009. The results of co- integration regression show that GDP and fraction urban population, both one lagged value, size of population and paid claims, both at contemporary value, have significant positive effect on aggregate insurance premium in Albania while the market share of the largest company in the insurance market, one lagged value, has significant negative effect on aggregate insurance premiums. Granger causality test shows statistically significance contribution of GDP growth to insurance premium growth, GDP drives insurance premium growth but not vice versa. The Albanian insurance market is under development, indicators as: insurance penetration, premium per capita, ect are still at low level and this can justify the insignificant role of the insurance in the economy

Public health practice has come to increasing recognition of health promotion and the central role of knowledge, attitude, beliefs and practices in achieving health promotion. Health literacy (HL) is an under-explored topic in South Eastern European countries. There are no HL reports from Albania to date. The aim of this study was to assess the concurrent validity of the European Health Literacy Survey Questionnaire (HLS-EU-Q) and the Test of Functional Health Literacy in Adults (TOFHLA) in a population-based sample of adults in Albania. A cross-sectional study was conducted in 2013 in Tirana, Albania, including 239 individuals aged ≥ 18 years (61% women; 87% response). A structured interviewer-administered questionnaire was applied twice (test and retest procedure after 2 weeks) including HLS-EU-Q and TOFHLA instruments. The internal consistency was high for both instruments (Cronbach's alpha for the test procedure was 0.92 for TOFHLA and 0.98 for HLS-EU-Q). Both tools exhibited a high stability over time (Spearman's rho: 0.88 for TOFHLA and 0.87 for HLS-EU). Mean values of both instruments were similar in men and women (mean score for TOFHLA: 76.0 vs. 76.5, P = 0.83; mean score for HLS-EU-Q: 32.2 vs. 32.6, P = 0.63). For both instruments, higher HL scores were significantly associated with younger age, higher educational and economic level and lower body mass index. Our study provides valuable novel evidence on concurrent validation of two major HL instruments in a South Eastern European population-based sample. Future studies should be conducted in order to confirm and expand our findings. © The Author 2014. Published by Oxford University Press on behalf of the European Public Health Association.

Full Text Available We already acepted that Croatian economical and geopolitical possition can bee improved only with better utilization of coastal area. Under these conditions mariculture also makes a part od sea master plan because demands for mariculture are focused on clean environmental conditions to obtain economic benefits. Increased pressure to the coastal area is global trend and if not planed and organized can provoke conflicts and can affect further development. Under these condition, marine aquaculture is frequent subject of many discussion focused on the environmental impact. Conflict of different interest in coastal area with no argumentation is putting marine aquaculture in worst position related with tourism and industry. Hard argumentations is laying in noneadequate frame of work in some facilities and to take advantake competitors are preasenting marine aquaculture in worst picture. Marine aquaculture product has to be health product, which can be completely damaged because of non-responsible approach of other activity. Mariculture also can suffer from self-pollution as for example tourism and must be well planed and managed. Fecal pollution from towns, pollution from bad controlled tourists activity, industry, influence of intensive and non controlled agriculture in coast line, are also potential danger for quality of all sea products and also cultured products from marine aquaculture. High quality of marine products can be obtained by zoning of coastal area, and in concept of these zoning it is necessary to define the zones for marine aquaculture. Procedure of zoning has to be divided in three steps: deetrmination of present status of area, definition of shore land for making mariculture related shore infrastructure and definitions of areas suitable for mariculture with limits of production. These can make positive situations with avoiding conflicts in exploitation of common resources in future. Zone for marine aquaculture has to be controlled

The potential for eEngineering enhanced functional-feed soybeans for sustainable aquaculture feed

Full Text Available Aquaculture is the most rapidly growing segment of global animal production that now surpasses wild-capture fisheries production and is continuing to grow 10% annually. Sustainable aquaculture needs to diminish, and progressively eliminate, its dependence on fishmeal-sourced feed from over-harvestedallocated fisheries. Sustainable aquafeed sources will need to be primarily of plant-origin. Soybean is currently the primary global vegetable-origin protein source for aquaculture. Direct exchange of soybean meal for fishmeal in aquafeed has resulted in reduced growth rates due in part to soybean’s anti-nutritional proteins. To produce an aquaculture soybeans for use in aquaculture feeds a new conventional line has been bred termed Triple Null by stacking null alleles for the feed-relevant proteins Kunitz Trypsin Inhibitor, lectin, and P34 allergen. Triple Null is now being further enhanced as a platform to build additional transgene traits for production disease vaccines, altered protein composition, and to produce high levels of -carotene an intrinsic orange-colored aquafeed marker to distinguish the seeds from commodity beans and as the metabolic feedstock precursor of highly valued astaxanthin.

2017-06-01

Fish from aquaculture is becoming more important for human consumption. Sustainable aquaculture procedures were developed as an alternative to overcome the negative environmental impacts of conventional aquaculture procedures and wild fisheries. The objective of this contribution is to determine what consumers expect from sustainable aquaculture and whether they prefer sustainable aquaculture products. A combination of qualitative research methods, with think aloud protocols and in-depth interviews, as well as quantitative methods, using choice experiments and face-to-face interviews, was applied. Data was collected in three different cities of Germany. Results revealed that sustainable aquaculture was associated with natural, traditional, local, and small scale production systems with high animal welfare standards. Overall, participants paid a lot of attention to the declaration of origin; in particular fish products from Germany and Denmark were preferred along with local products. Frequently used sustainability claims for aquaculture products were mostly criticized as being imprecise by the participants of the qualitative study; even though two claims tested in the choice experiments had a significant positive impact on the choice of purchase. Similarly, existing aquaculture-specific labels for certified sustainable aquaculture had an impact on the buying decision, but were not well recognized and even less trusted. Overall, consumers had a positive attitude towards sustainable aquaculture. However, communication measures and labelling schemes should be improved to increase consumer acceptance and make a decisive impact on consumers' buying behavior. Copyright © 2017 Elsevier Ltd.

Sustainable Treatment of Aquaculture Effluents—What Can We Learn from the Past for the Future?

Directory of Open Access Journals (Sweden)

Ariel E. Turcios

2014-02-01

Full Text Available Many aquaculture systems generate high amounts of wastewater containing compounds such as suspended solids, total nitrogen and total phosphorus. Today, aquaculture is imperative because fish demand is increasing. However, the load of waste is directly proportional to the fish production. Therefore, it is necessary to develop more intensive fish culture with efficient systems for wastewater treatment. A number of physical, chemical and biological methods used in conventional wastewater treatment have been applied in aquaculture systems. Constructed wetlands technology is becoming more and more important in recirculating aquaculture systems (RAS because wetlands have proven to be well-established and a cost-effective method for treating wastewater. This review gives an overview about possibilities to avoid the pollution of water resources; it focuses initially on the use of systems combining aquaculture and plants with a historical review of aquaculture and the treatment of its effluents. It discusses the present state, taking into account the load of pollutants in wastewater such as nitrates and phosphates, and finishes with recommendations to prevent or at least reduce the pollution of water resources in the future.

What shapes food value chains? Lessons from aquaculture in Asia

2014-01-01

In this article, we explain what shapes food value chains through the analysis of selected aquaculture industries in four key Asian producing countries. Worldwide production of aquatic resources has grown rapidly in the past few decades, and aquaculture production in Asia has played a decisive role...... in this growth. We examine the main forms of coordination found along these value chains and the role that institutional frameworks play in governing them. We observe that negative publicity, driven by NGO and media campaigns, has led to increased use of third-party certification and the adoption of public...... and private standards. We find that the most sophisticated aquaculture operations in Asia are found in value chains led by retailers and branded processors and where the quality of domestic institutional frameworks has facilitated compliance with increasing demands from buyers overseas. Finally, we reflect...

Lessons from two high CO2 worlds - future oceans and intensive aquaculture.

Science.gov (United States)

Ellis, Robert P; Urbina, Mauricio A; Wilson, Rod W

2017-06-01

Exponentially rising CO 2 (currently ~400 μatm) is driving climate change and causing acidification of both marine and freshwater environments. Physiologists have long known that CO 2 directly affects acid-base and ion regulation, respiratory function and aerobic performance in aquatic animals. More recently, many studies have demonstrated that elevated CO 2 projected for end of this century (e.g. 800-1000 μatm) can also impact physiology, and have substantial effects on behaviours linked to sensory stimuli (smell, hearing and vision) both having negative implications for fitness and survival. In contrast, the aquaculture industry was farming aquatic animals at CO 2 levels that far exceed end-of-century climate change projections (sometimes >10 000 μatm) long before the term 'ocean acidification' was coined, with limited detrimental effects reported. It is therefore vital to understand the reasons behind this apparent discrepancy. Potential explanations include 1) the use of 'control' CO 2 levels in aquaculture studies that go beyond 2100 projections in an ocean acidification context; 2) the relatively benign environment in aquaculture (abundant food, disease protection, absence of predators) compared to the wild; 3) aquaculture species having been chosen due to their natural tolerance to the intensive conditions, including CO 2 levels; or 4) the breeding of species within intensive aquaculture having further selected traits that confer tolerance to elevated CO 2 . We highlight this issue and outline the insights that climate change and aquaculture science can offer for both marine and freshwater settings. Integrating these two fields will stimulate discussion on the direction of future cross-disciplinary research. In doing so, this article aimed to optimize future research efforts and elucidate effective mitigation strategies for managing the negative impacts of elevated CO 2 on future aquatic ecosystems and the sustainability of fish and shellfish

Attitudinal Factors and Personal Characteristics Influence Support for Shellfish Aquaculture in Rhode Island (US) Coastal Waters.

Science.gov (United States)

Dalton, Tracey M; Jin, Di

2018-05-01

This study explores public interests associated with shellfish aquaculture development in coastal waters of Rhode Island (US). Specifically, we examine (1) the levels of public support for (or opposition to) shellfish aquaculture development and (2) factors driving the levels of support, using survey data and ordinal logistic regressions. Results of the analysis identify several key attitudinal factors affecting individual's support for shellfish aquaculture in Rhode Island (RI). The level of support is positively associated with attitudes related to shellfish aquaculture's benefits to the local economy and its role as a nutritional food option, and negatively influenced by attitudes related to aquaculture farms' effects on aesthetic quality and their interference with other uses. Findings highlight that support for (or opposition to) aquaculture in RI is driven more by attitudes associated with social impacts than by those associated with environmental impacts. The level of support is also affected by personal characteristics related to an individual's participation in recreational activities. For instance, bicycle riders tend to be supportive of shellfish aquaculture while respondents who participate in sailing and birding are less supportive. By identifying the broader public's interests in shellfish aquaculture, findings from this study and others like it can be used to address public concerns, incorporate public perceptions and attitudes into permitting decisions, and develop outreach targeted at specific stakeholder groups.

Aquaculture: a rapidly growing and significant source of sustainable food? Status, transitions and potential.

Science.gov (United States)

Little, D C; Newton, R W; Beveridge, M C M

2016-08-01

The status and potential of aquaculture is considered as part of a broader food landscape of wild aquatic and terrestrial food sources. The rationale and resource base required for the development of aquaculture are considered in the context of broader societal development, cultural preferences and human needs. Attention is drawn to the uneven development and current importance of aquaculture globally as well as its considerable heterogeneity of form and function compared with established terrestrial livestock production. The recent drivers of growth in demand and production are examined and the persistent linkages between exploitation of wild stocks, full life cycle culture and the various intermediate forms explored. An emergent trend for sourcing aquaculture feeds from alternatives to marine ingredients is described and the implications for the sector with rapidly growing feed needs discussed. The rise of non-conventional and innovative feed ingredients, often shared with terrestrial livestock, are considered, including aquaculture itself becoming a major source of marine ingredients. The implications for the continued expected growth of aquaculture are set in the context of sustainable intensification, with the challenges that conventional intensification and emergent integration within, and between, value chains explored. The review concludes with a consideration of the implications for dependent livelihoods and projections for various futures based on limited resources but growing demand.

Aquaculture research and management in the telecoupled Belt and Road Initiative countries and beyond

Yang, W.; Ying, Z.; Marín, T.

2017-12-01

Due to the continuous growth in aquatic product consumption, globally the total production of aquatic products has increased by 20% in the past two decades. In 2014, for the first time, the production of aquatic products for direct human consumption from aquaculture surpassed that of wild catch. In 2016, the total production of global aquatic products reached 170 million tons, of which 45% comes from the aquaculture sector. More importantly, over 80% of the global aquaculture production occurs in the Belt and Road Initiative countries. Particularly, China alone contributes to two third of the global share. The rapid expansion and intensification of aquaculture have many environmental and socioeconomic impacts both at the cultivation places and also in places where feed is produced; however, these telecoupled processes and effects are largely unknown in a quantitative manner. Here, we apply the telecoupling framework to analyze the aquaculture trade among China and other Belt and Road Initiative countries and beyond. The integrated telecoupling framework helps to demonstrate the environmental and socioeconomic interactions among the feed (and aquatic product) sending, receiving, and spillover systems. It also provides a platform to model the telecoupled processes and effects across multiple remotely connected systems. Moreover, the application of the framework reveals many research gaps and management needs on aquaculture research and management.

Fishmeal Supplier Evaluation and Selection for Aquaculture Enterprise Sustainability with a Fuzzy MCDM Approach

Directory of Open Access Journals (Sweden)

Tsung-Hsien Wu

2017-11-01

Full Text Available In the aquaculture industry, feed that is of poor quality or nutritionally imbalanced can cause problems including low weight, poor growth, poor palatability, and increased mortality, all of which can induce a decrease in aquaculture production. Fishmeal is considered a better source of protein and its addition as an ingredient in the aquafeed makes aquatic animals grow fast and healthy. This means that fishmeal is the most important feed ingredient in aquafeed for the aquaculture industry. For the aquaculture industry in Taiwan, about 144,000 ton/USD $203,245,000 of fishmeal was imported, mostly from Peru, in 2016. Therefore, the evaluation and selection of fishmeal suppliers is a very important part of the decision-making process for a Taiwanese aquaculture enterprise. This study constructed a multiple criteria decision-making evaluation model for the selection of fishmeal suppliers using the VlseKriterijumska Optimizacija I Kompromisno Resenje (VIKOR approach based on the weights obtained with the entropy method in a fuzzy decision-making environment. This hybrid approach could effectively and conveniently measure the comprehensive performance of the main Peruvian fishmeal suppliers for practical applications. In addition, the results and processes described herein function as a good reference for an aquaculture enterprise in making decisions when purchasing fishmeal.

Economic Valuation of Mangroves for Comparison with Commercial Aquaculture in South Sulawesi, Indonesia

Directory of Open Access Journals (Sweden)

Abdul Malik

2015-08-01

Full Text Available Mangroves are recognized as a provider of a variety of products and essential ecosystem services that contribute significantly to the livelihood of local communities. However, over the past decades, mangroves in many tropical areas including the Takalar district, South Sulawesi have degraded and decreased mainly due to conversion to aquaculture. Currently, little is known about the economic benefits of commercialization of aquaculture as compared to those derived from mangroves in the form of products and services. Here, we estimate the Total Economic Value (TEV of mangrove benefits in order to compare it with the benefit value of commercial aquaculture. Market prices, replacement costs, benefit transfer value and Cost-Benefit Analyses (CBA have been used for value determination and comparison. The results show that the per year TEV of mangroves in the study area (Takalar district, South Sulawesi was in the range of 4370 thousands USD (kUSD to 10,597 kUSD or 4 kUSD to 8 kUSD per hectare (the highest value contribution derived from the indirect use value (94%, whereas commercial aquaculture had a net benefit value of 228 kUSD or 3 kUSD per hectare. In addition, the comparison of Net Present Value (NPV between the benefit value of mangroves and that of commercial aquaculture revealed that conversion of mangroves into commercial aquaculture was not economically beneficial when the analysis was expanded to cover the costs of environmental and forest rehabilitation.

Fishery and Aquaculture Relationship in the Mediterranean: Present and Future

Directory of Open Access Journals (Sweden)

G. RELINI

2003-12-01

Full Text Available Although the Mediterranean represents only 0.8% of the world seas, it is the site of a very long-established fishing activity, characterized mainly by multispecific catch and by artisanal or coastal activity, resulting from a mosaic of very diversified structures and gears, along more than 45,000 km of coastline. Two main biological features of this sea are the occurrence of a large richness of species (it represents 5.5% - 7% of world marine fauna and 16.6% of macrophyta, which stands in contrast with its ‘trophic poverty’ and the absence of large monospecific fishery, except for some small and large pelagic fish. Another biological characteristic of Mare Nostrumis the high invasion of exotic species, some exploited by fishery and aquaculture, some others quite dangerous. For the entire Mediterranean and Black Sea, the production (catch + aquaculture had been steadily increasing over the period 1972-1988 from 1,140,000 t to 2,080,000 t . The period 1988-1991 has shown a drastic drop in catches (in 1991: 1,400,000 t. From 1990 to 1995 the total catch increased to 1,701,379 t then decreased and in 2000 reached 1,485,046 t . In 2000 Turkey had the first place with 496,174 t, 26.9% of the total value (1,846,026 t, including fishing and aquaculture, followed by Italy with 25%, Greece 9%, Spain 7.6% and Algeria 5.4%. As in many parts of the world, aquaculture production in the Mediterranean is rapidly expanding. In 1970 the total aquaculture production was about 18,297 t of which 74.3% produced in Italy. In 2000 a value of 358,614 t was reached, about 1/4 of the total fishery catch, while the world aquaculture production corresponds to half of the world total catch. Italy is still the main producer with 46.7% , followed by Greece with 21.5%, Turkey 9.9% and France 6.7%. A sharp drop in the production of the European eel ( Anguilla anguilla and of the European flat oyster ( Ostrea edulis is recorded. Positive and negative interactions between

Full Text Available The ever-increasing need to communicate and be up to date with language as it changes and is used in global interactions imposes on learners and teachers of foreign languages the need to consider all proven and meaningful means of language acquisition in order to develop skills and competences. Through a review of literature we can reiterate and properly evaluate the traditional role of literary texts in our teaching process, but it is through our practical considerations and efforts within the classroom setting, through detailed and conspicuous patterns of literature, that we can feel its immense power and results on our students. This paper aims at highlighting the impact of drama in our students’ learning process, how it fosters autonomy, eagerness, motivation and creativity. These will be reinforced in a case study organized with the English Study Skills class in the Faculty of Foreign Languages, University of Tirana, Albania.

Sustainable Development Aspects in Cross-Border Cooperation Programmes: The Case of Macedonia and Albania

Full Text Available The cross-border area between Albania and Macedonia can be considered as a region with agrarian or industrial-agrarian economy, although the overall picture should take into account significant contrasts within the region, between the two countries, but also between the southern and northern part, and between mountainous areas and lowlands. Agriculture, agribusiness, light industry, mining, energy production and tourism are the main economic sectors, which also have the biggest potential in the cross-border region. Both countries are gaining experience in EU funded cross-border cooperation programmes with other neighbouring countries and with each other. The scope of the research is the evaluation and analysis of the Integrated Pre-accession Assistance (IPA Cross-border Cooperation (CBC Programme Macedonia-Albania 2007-2013 and its sustainable development aspects. The research is trying to assess the impact of the programme since its start in 2007 and the impact of the implemented grants on the sustainable development. The importance of the sustainable development aspect is recognized and is formally included into various national strategic documents, however implementation is often problematic and sustainability aspects need to be examined on a more concrete level. The methodology used was qualitative with research tools such as desk studies of relevant program documentation, strategic and planning documentation and other relevant published materials. The desk review considered well over 40 documents relevant to the program, most of which were shared by the Ministry of European Integration (MoEI and other actors.

Microplastics in the context of regulation of commercial shellfish aquaculture operations.

Science.gov (United States)

Schoof, Rosalind A; DeNike, Jesse

2017-05-01

Shellfish aquaculture in the Salish Sea (encompassing the Strait of Juan de Fuca, Puget Sound, and the Georgia Strait) is a major source of clams, oysters, and mussels in the United States and Canada. Plastic gear is necessary for the viability of many of these operations. During the past few years, shellfish farm permits issued in Washington State have been challenged on various bases that have included allegations that the plastic gear is releasing microplastics, commonly defined as particles less than 5 mm in diameter. Published survey data on sources of marine plastic debris demonstrate the very limited contribution of aquaculture gear. Both permits and industry codes of practice provide procedures to minimize loss of gear to the marine environment. Plastic gear is also designed specifically to maintain its integrity and not degrade in the marine environment.

The aquaculture industry has grown dramatically, and plays an important role in the world's food supply chain. Antimicrobial resistance in bacteria associated with food animals receives much attention, and drug use in aquaculture is also an important issue. There are many differences between aquatic and terrestrial management systems, such as the methods used for administration of drugs. Unique problems are related to the application of drugs in aquatic environments. Residual drugs in fish products can affect people who consume them, and antimicrobials released into aquatic environments can select for resistant bacteria. Moreover, these antimicrobial-resistant bacteria, or their resistance genes, can be transferred to humans. To decrease the risks associated with the use of antimicrobials, various regulations have been developed. In addition, it is necessary to prevent bacterial diseases in aquatic animals by vaccination, to improve culture systems, and to monitor the amount of antimicrobial drugs used and the prevalence of antimicrobial-resistant bacteria.

Antimicrobials are heavily used in Chilean salmon aquaculture. We previously found significant differences in antimicrobial-resistant bacteria between sediments from an aquaculture and a non-aquaculture site. We now show that levels of antimicrobial resistance genes (ARG) are significantly higher in antimicrobial-selected marine bacteria than in unselected bacteria from these sites. While ARG in tetracycline- and florfenicol-selected bacteria from aquaculture and non-aquaculture sites were equally frequent, there were significantly more plasmid-mediated quinolone resistance genes per bacterium and significantly higher numbers of qnrB genes in quinolone-selected bacteria from the aquaculture site. Quinolone-resistant urinary Escherichia coli from patients in the Chilean aquacultural region were significantly enriched for qnrB (including a novel qnrB gene), qnrS, qnrA and aac(6')-1b, compared with isolates from New York City. Sequences of qnrA1, qnrB1 and qnrS1 in quinolone-resistant Chilean E. coli and Chilean marine bacteria were identical, suggesting horizontal gene transfer between antimicrobial-resistant marine bacteria and human pathogens. © 2015 Society for Applied Microbiology and John Wiley & Sons Ltd.

The present study elucidated the presence of antibiotics resistance, virulence genes and biofilm potentials among Aeromonas species isolated from abattoir and aquaculture environments in Benin City, Nigeria. A total of 144 wastewater samples were obtained from two independent aquaculture and abattoir environments between May and October 2016. Aeromonas species were isolated on Glutamate Starch Phenol Red (GSP) agar and confirmed using API 20NE kits. Antimicrobial susceptibility profile of the isolates was carried out using standard disc diffusion assay while biofilm potentials were detected by the microtitre plate method and PCR technique was used to detect antibiotics resistance and virulence gene markers. Overall, 32 and 26 Aeromonas species were isolated from the abattoir and aquaculture environments respectively. Isolates from both environments were completely resistant (100%) to penicillin G, ertapenem and tetracycline; whereas aquaculture isolates exhibited absolute sensitivity (100%) towards cefepime. All the virulence gene markers (aerA, hlyA, alt, ast, laf, ascF-G, fla, lip, stx1, and stx2) investigated in this study (except laf) were detected in isolates from both environments. The laf genes were only detected in isolates from abattoir environments. Antibiotics resistant genes including pse, bla TEM and class 1 integron were detected in isolates from both environments. Majority of the isolates (53/58 91.4%) from both environments; demonstrated capacity for biofilm potential. The detection of antibiotic resistance and virulence gene markers as well as biofilm forming ability in Aeromonas species isolated from aquaculture and abattoir environments raise serious public health concern worthy of further investigation.

Deniz, H.

2003-04-01

Turkey, with 8333 km of coast line, 151 080 sq. km economic sea area, many rivers with 177 714 total length, nearly, 1 million ha of natural lakes, 500 000 ha of dam reservoirs has rich marine and inland aquatic resource potential. Despite of these large resources, Turkish fisheries has the characteristics of small-scale fisheries and in general it can be considered as coastal fisheries. There is also great potential for inland fisheries and aquaculture. Being in half closed position, these seas have different characteristics in respect of biological, physical, chemical and ecological points. In addition; Turkey has favourable geographic position between the Black Sea and Mediterranean Sea. Nevertheless, this potential seems not to be fully utilised and therefore fisheries is not a major sector in the economy. According to the statistics of the fisheries for 2000 published by the Turkish government, Turkey's total fisheries production was 582.376 tons. Total catch consists sea fish (441 690 tons, crustaceans and molluscs (18 831 tons), freshwater fish (42.824 tons) and aquaculture (79. 031 tons). The Ministry of Agriculture and Rural Affairs (MARA) is the Ministry responsible for the overall fisheries and aquaculture development, administration, regulation, promotion and technical assistance. In the past two decades, marine fish farming using net cages has developed in the coastal waters throughout Turkey. Such fish farming has allowed the production of large amounts of valuable fish and their supply to the internal and external markets on a regular basis. However, fish farming is sometimes fallowed by organic pollution of the water and bottom sediment in the vicinity of the cages. A comprehensive land and coastal planning survey of almost the whole coast of Turkey is currently being conducted. This master plan designates areas to be developed for forestry, agriculture, industry, urbanisation, environmentally protected areas, etc. The plan was undertaken before the

Lehnen, Sarah E; Krementz, David G

2013-08-01

Populations of many shorebird species are declining; habitat loss and degradation are among the leading causes for these declines. Shorebirds use a variety of habitats along interior migratory routes including managed moist soil units, natural wetlands, sandbars, and agricultural lands such as harvested rice fields. Less well known is shorebird use of freshwater aquaculture facilities, such as commercial cat- and crayfish ponds. We compared shorebird habitat use at drained aquaculture ponds, moist soil units, agricultural areas, sandbars and other natural habitat, and a sewage treatment facility in the in the lower Mississippi River Alluvial Valley (LMAV) during autumn 2009. Six species: Least Sandpiper (Calidris minutilla), Killdeer (Charadrius vociferous), Semipalmated Sandpiper (Calidris pusilla), Pectoral Sandpiper (C. melanotos), Black-necked Stilt (Himantopus himantopus), and Lesser Yellowlegs (Tringa flavipes), accounted for 92 % of the 31,165 individuals observed. Sewage settling lagoons (83.4, 95 % confidence interval [CI] 25.3-141.5 birds/ha), drained aquaculture ponds (33.5, 95 % CI 22.4-44.6 birds/ha), and managed moist soil units on public lands (15.7, CI 11.2-20.3 birds/ha) had the highest estimated densities of shorebirds. The estimated 1,100 ha of drained aquaculture ponds available during autumn 2009 provided over half of the estimated requirement of 2,000 ha by the LMAV Joint Venture working group. However, because of the decline in the aquaculture industry, autumn shorebird habitats in the LMAV may be limited in the near future. Recognition of the current aquaculture habitat trends will be important to the future management activities of federal and state agencies. Should these aquaculture habitat trends continue, there may be a need for wildlife biologists to investigate other habitats that can be managed to offset the current and expected loss of aquaculture acreages. This study illustrates the potential for freshwater aquaculture to

A history of fish vaccination: science-based disease prevention in aquaculture.

Gudding, Roar; Van Muiswinkel, Willem B

2013-12-01

Disease prevention and control are crucial in order to maintain a sustainable aquaculture, both economically and environmentally. Prophylactic measures based on stimulation of the immune system of the fish have been an effective measure for achieving this goal. Immunoprophylaxis has become an important part in the successful development of the fish-farming industry. The first vaccine for aquaculture, a vaccine for prevention of yersiniosis in salmonid fish, was licensed in USA in 1976. Since then the use of vaccines has expanded to new countries and new species simultaneous with the growth of the aquaculture industry. This paper gives an overview of the achievements in fish vaccinology with particular emphasis on immunoprophylaxis as a practical tool for a successful development of bioproduction of aquatic animals.

2018-03-01

The purpose of this study were to determine characteristics and environmental carrying capacities of coastal area in Yogyakarta Special Region for aquaculture. This study was conducted in 2015 by characterizing land and water dynamics, land use, and the suitability of coastal environments for aquaculture. Evaluation on the coastal environments suitability for aquaculture ponds was based on the landforms, soil properties, water quality and land. Selection of coastal locations for aquaculture development was based on the level of suitability of coastal environment. The results showed that the coastal in Kulon Progo and Bantul Regencies were characterized by sand dune and beach ridge with sandy soil texture, while in Gunungkidul Regency was characterized by limestone hill with rocky texture. Water sources of the coastal area were the sea, river, and ground water with the salinity of 31–37, 7–11, 7–31 ppt and pH of 7.4–8.4 7.0–8.2 and 7.4–9.9, respectively. The coastal lands were used for seasonal/annual planting, ponds, fish landing sites, tourism areas and conservation areas. The coastal carrying capacity was rather suitable for aquaculture, especially in the sandy soil area. Aquaculture in that area can be done intensively for shrimp (Litopenaeus vannamei), using biocrete (biological material) or plastic sheet.

The Potential for Engineering Enhanced Functional-Feed Soybeans for Sustainable Aquaculture Feed.

Science.gov (United States)

Herman, Eliot M; Schmidt, Monica A

2016-01-01

Aquaculture is the most rapidly growing segment of global animal production that now surpasses wild-capture fisheries production and is continuing to grow 10% annually. Sustainable aquaculture needs to diminish, and progressively eliminate, its dependence on fishmeal-sourced feed from over-harvested fisheries. Sustainable aquafeed sources will need to be primarily of plant-origin. Soybean is currently the primary global vegetable-origin protein source for aquaculture. Direct exchange of soybean meal for fishmeal in aquafeed has resulted in reduced growth rates due in part to soybean's anti-nutritional proteins. To produce soybeans for use in aquaculture feeds a new conventional line has been bred termed Triple Null by stacking null alleles for the feed-relevant proteins Kunitz Trypsin Inhibitor, lectin, and P34 allergen. Triple Null is now being further enhanced as a platform to build additional transgene traits for vaccines, altered protein composition, and to produce high levels of β-carotene an intrinsic orange-colored aquafeed marker to distinguish the seeds from commodity beans and as the metabolic feedstock precursor of highly valued astaxanthin.

Risks of Using Antifouling Biocides in Aquaculture

Guardiola, Francisco Antonio; Cuesta, Alberto; Meseguer, José; Esteban, Maria Angeles

2012-01-01

Biocides are chemical substances that can deter or kill the microorganisms responsible for biofouling. The rapid expansion of the aquaculture industry is having a significant impact on the marine ecosystems. As the industry expands, it requires the use of more drugs, disinfectants and antifoulant compounds (biocides) to eliminate the microorganisms in the aquaculture facilities. The use of biocides in the aquatic environment, however, has proved to be harmful as it has toxic effects on the marine environment. Organic booster biocides were recently introduced as alternatives to the organotin compounds found in antifouling products after restrictions were imposed on the use of tributyltin (TBT). The replacement products are generally based on copper metal oxides and organic biocides. The biocides that are most commonly used in antifouling paints include chlorothalonil, dichlofluanid, DCOIT (4,5-dichloro-2-n-octyl-4-isothiazolin-3-one, Sea-nine 211®), Diuron, Irgarol 1051, TCMS pyridine (2,3,3,6-tetrachloro-4-methylsulfonyl pyridine), zinc pyrithione and Zineb. There are two types of risks associated with the use of biocides in aquaculture: (i) predators and humans may ingest the fish and shellfish that have accumulated in these contaminants and (ii) the development of antibiotic resistance in bacteria. This paper provides an overview of the effects of antifouling (AF) biocides on aquatic organisms. It also provides some insights into the effects and risks of these compounds on non-target organisms.

Sustainable aquaculture of Asian arowana--a review.

Science.gov (United States)

Medipally, S R; Yusoff, F M; Sharifhuddin, N; Shariff, M

2016-07-01

Asian arowana, Scleropages formosus is a highly valued aquarium fish in the world, particularly in Asian countries, and has been listed as one of the most highly endangered species. This is a freshwater, carnivorous, fairly large mouth breeding fish belonging to the family Osteoglossidae. Arowana can be found in different colour varieties such as green, red, silver and golden. Among these varieties, Malaysian golden is the most valuable fish and is endemic to the Krian riverine system, Malaysia. However, overexploitation, habitat change and pollution have caused a serious decline of this arowana variety. Recently, arowana aquaculture industry is expanding rapidly in Southeast Asian countries. However, difficulties in an accurate differentiation of sex and strains, causing imbalanced stocking ratios for optimum spawning, remain major obstacles in maximizing arowana production. In addition, problems in sustainable water sources of suitable quality and prevention of diseases need to be addressed. Recirculating aquaculture system (RAS) and bioremediation are two possible technologies that could be used to minimize pollution and ensure adequate high-quality water for arowana culture. In addition, the application of appropriate molecular markers for sex and strain identification is also an important strategy required for the improvement of captive breeding. This review discusses several issues such as the importance of arowana as an aquarium fish, its market demand, current problems in the arowana aquaculture industry and the possible technologies to enhance reproductive capacity and increase culture production. ?

Social Dynamics Shaping the Diffusion of Sustainable Aquaculture Innovations in the Solomon Islands

Directory of Open Access Journals (Sweden)

Jessica Blythe

2017-01-01

Full Text Available Sustainably feeding the world’s growing population represents one of our most significant challenges. Aquaculture is well positioned to make contributions towards this challenge. Yet, the translation of aquaculture production innovations into benefits for rural communities is constrained by a limited understanding of the social dynamics that influence the adoption of new agricultural practices. In this paper, we investigate the factors that shape the spread of small-scale tilapia aquaculture through rural Solomon Islands. Based on diffusion of innovation theory, we focus on three potentially influential factors: (i socio-economic characteristics of adopters; (ii the role of opinion leaders; and (iii characteristics of the innovation. We find that farmers who were wealthier, older, and had more diverse livelihoods were most likely to be adopters. Opinion leaders facilitated the adoption of tilapia aquaculture, but lacked the capacity to provide fundamental knowledge necessary to realize its potential benefits to food security. The paper argues for more explicit attention to the poorest households and makes the case for a deeper engagement with the broader social and institutional contexts that shape the adoption process. Aquaculture interventions that account for these social dynamics are critical for translating production innovations into sustainable benefits to rural communities.

The growth of world population has led to significant increase in seafood demand over the world. Aquaculture has been widely accepted by many countries to increase the seafood production owing to the decline of natural seafood resources. The aquaculture productivity, however, is directly linked to the pond water quality. In this study, attempts were made to employ ceramic micro-filter to improve the pond water quality through filtration processes. There were two batches of filtration processes, short term (1 hour) and long term (48 hours). Significant improvements on real pond water quality were recorded through the short term microfiltration process, which reduced turbidity (96%), total suspended solids (TSS) (80%), biochemical oxygen demand (BOD) (72%), chemical oxygen demand (COD) (55%), ammonia (60%), nitrate (96%) and phosphorus (83%). The long term filtration process also showed high efficiency in the removal of solid particle and organic matters. The results showed that all of the parameters were successfully reduced to acceptable ranges (turbidityfiltered pond water. Current study showed that the microfiltration using ceramic micro-filter has high potential to be used in recirculating aquaculture system throughout the aquaculture activities in order to maintain the pond water quality, thus, increase the survival rate of cultured species.

Predicting shifting sustainability tradeoffs in marine finfish aquaculture under climate change.

Defining sustainability goals is a crucial but difficult task because it often involves the quantification of multiple interrelated and sometimes conflicting components. This complexity may be exacerbated by climate change, which will increase environmental vulnerability in aquaculture and potentially compromise the ability to meet the needs of a growing human population. Here, we developed an approach to inform sustainable aquaculture by quantifying spatio-temporal shifts in critical trade-offs between environmental costs and benefits using the time to reach the commercial size as a possible proxy of economic implications of aquaculture under climate change. Our results indicate that optimizing aquaculture practices by minimizing impact (this study considers as impact a benthic carbon deposition ≥ 1 gC m -2 d -1 ) will become increasingly difficult under climate change. Moreover, an increasing temperature will produce a poleward shift in sustainability trade-offs. These findings suggest that future sustainable management strategies and plans will need to account for the effects of climate change across scales. Overall, our results highlight the importance of integrating environmental factors in order to sustainably manage critical natural resources under shifting climatic conditions.

Enhancement of existing geothermal resource utilization by cascading to intensive aquaculture

Energy Technology Data Exchange (ETDEWEB)

Zachritz, W.H., II; Polka, R.; Schoenmackers

1996-04-01

A demonstration high rate aquaculture production system utilizing a cascaded geothermal resource was designed, constructed and operated to fulfill the objectives of this project. Analysis of the energy and water balances for the system indicated that the addition of an Aquaculture Facility expanded the use of the existing resource. This expanded use in no way affected the up- stream processes. Analysis of the system`s energy and water requirements indicated that the present resource was under-utilized and could be expanded. Energy requirements appeared more limiting than water use, but the existing system could be expanded to a culture volume of 72,000 gal. This system would have a potential production capacity of 93,600 lb/yr with a potential market value of $280,00/yr. Based on the results of this study, the heat remaining in the geothermal fluid from one square foot of operating greenhouse is sufficient to support six gallons of culture water for a high density aquaculture facility. Thus, the over 1.5M ft{sup 2} of existing greenhouse space in New Mexico, has the potential to create an aquaculture industry of nearly 9M gal. This translates to an annual production potential of 11.7M lb with a market value of $35.lM.

Behavioral observations of the endangered Rio Grande silvery minnow in a conservation aquaculture facility

Directory of Open Access Journals (Sweden)

Tave Douglas

2018-03-01

Full Text Available A major reason why conservation aquaculture is needed to improve the success of aquaculture-assisted fisheries is that traditional production aquaculture produces fish with mal-adaptive behaviors. These behaviors can be produced via domestication and culture techniques, and preventing these mal-adaptive behaviors requires integrating improvements in genetic management and culture protocols. The genetic protocols needed to minimize hatchery-induced genetic changes have received considerable attention, but changing the way fish are raised has received less effort. Conservation aquaculture cultures fish in environments that resemble their native habitats so that when stocked, they behave like wild fish rather than hatchery fish. A purpose built-conservation aquaculture facility can also be used to learn about a species’ behavior and how it reacts to changes in the environment, something which can be difficult or expensive to study in the wild. These observations can then be used to help direct both propagation and recovery management. This paper provides the rationale for why genetic management, culture systems, and management practices need to be altered to produce fish that are behaviorally similar to wild fish for aquaculture-assisted fisheries programs. It then provides a description of some of the behaviors of the endangered Rio Grande silvery minnow Hybognathus amarus that were observed at the Los Lunas Silvery Minnow Refugium, a purpose-built conservation aquaculture facility, and explains how some of these behaviors can be used in culture and recovery management. Behaviors described are: schooling; predator avoidance; feeding behavior; use of vegetation for cover and predator avoidance; habitat use by bottom substrate; location in the water column; upstream movement via a fish ladder; movement upstream in a high-velocity channel; response to changes in water level; spawning behavior; seine avoidance; and Kaah-chee-nyee Srkaash, a behavior

Criteria for candidate species for aquaculture

Energy Technology Data Exchange (ETDEWEB)

Webber, H H; Riordan, P F

1976-01-01

The nature of the animal taxa that are the most probable candidates for an intensive, commercial aquatic animal husbandry industry is considered. A characterization is presented of those biological criteria that lend the species the necessary physiological and genetic malleability to be adapted and molded into a domesticated race. The animal cultivated must be amenable to intensive management in high-density confinements such as those now being engineered for high-yield aquaculture. Attributes considered are discussed in the context of the various aquacultural ecosystems in which the specific biotype is expected to achieve satisfactory growth and survival. Correlative with bionomic criteria, economic requirements are posed and evaluated in an effort to define a socially and financially profitable agribusiness system. Investment requirements and operating costs are considered in terms of expected returns. However, since production alone is insufficient to sustain an enterprise - i.e., the product must be sold - production costs must be judged against market values. Therefore, ultimate use or consumer acceptance criteria are incorporated into the list of essential requirements for a candidate species for aquafarming.

Governments and other stakeholders are seeking strategies to boost food production efficiency and food system resiliency, and aquaculture (farmed seafood) is commonly viewed as having a major role in improving global food security based on longstanding measures of animal production efficiency. The most widely used measurement is called the ‘feed conversion ratio’ (FCR), which is the weight of feed administered over the lifetime of an animal divided by weight gained. By this measure, fed aquaculture and chickens are similarly efficient at converting feed into animal biomass, and both are more efficient compared to pigs and cattle. FCR does not account for differences in feed content, edible portion of an animal, or nutritional quality of the final product. Given these limitations, we searched the literature for alternative efficiency measures and identified ‘nutrient retention’, which can be used to compare protein and calories in feed (inputs) and edible portions of animals (outputs). Protein and calorie retention have not been calculated for most aquaculture species. Focusing on commercial production, we collected data on feed composition, feed conversion ratios, edible portions (i.e. yield), and nutritional content of edible flesh for nine aquatic and three terrestrial farmed animal species. We estimate that 19% of protein and 10% of calories in feed for aquatic species are ultimately made available in the human food supply, with significant variation between species. Comparing all terrestrial and aquatic animals in the study, chickens are most efficient using these measures, followed by Atlantic salmon. Despite lower FCRs in aquaculture, protein and calorie retention for aquaculture production is comparable to livestock production

Coastal embayments are at risk of impacts by climate change drivers such as ocean warming, sea level rise and alteration in precipitation regimes. The response of the ecosystem to these drivers is highly dependent on their magnitude of change, but also on physical characteristics such as bay morphology and river discharge, which play key roles in water residence time and hence estuarine functioning. These considerations are especially relevant for bivalve aquaculture sites, where the cultured biomass can alter ecosystem dynamics. The combination of climate change, physical and aquaculture drivers can result in synergistic/antagonistic and nonlinear processes. A spatially explicit model was constructed to explore effects of the physical environment (bay geomorphic type, freshwater inputs), climate change drivers (sea level, temperature, precipitation) and aquaculture (bivalve species, stock) on ecosystem functioning. A factorial design led to 336 scenarios (48 hydrodynamic × 7 management). Model outcomes suggest that the physical environment controls estuarine functioning given its influence on primary productivity (bottom-up control dominated by riverine nutrients) and horizontal advection with the open ocean (dominated by bay geomorphic type). The intensity of bivalve aquaculture ultimately determines the bivalve-phytoplankton trophic interaction, which can range from a bottom-up control triggered by ammonia excretion to a top-down control via feeding. Results also suggest that temperature is the strongest climate change driver due to its influence on the metabolism of poikilothermic organisms (e.g. zooplankton and bivalves), which ultimately causes a concomitant increase of top-down pressure on phytoplankton. Given the different thermal tolerance of cultured species, temperature is also critical to sort winners from losers, benefiting Crassostrea virginica over Mytilus edulis under the specific conditions tested in this numerical exercise. In general, it is

Full Text Available This article describes the ongoing project “School for Cultural Heritage through Map Exploitation” (SCHEME, an integrated set of activities designed to support social inclusion in heritage promotion processes in Albania. The main project goal is delivering ICT tools (map and crowdfunding platforms and procedures as well as improving the capacity of stakeholders to sustainably valorize hidden resources. The underlying approach has capitalized on existing technologies and experiences through the development of an advanced interactive multimedia map using data produced in the Ljubljana Process. Subsequently, the map will be extended by collecting more data on the Lake Ohrid Region, which has been selected as a pilot area to promote the neglected inland, relieving pressure on more famous coastal sites. A contest among schools will enrich the database, uploading multifaceted memories collected by students. The winning cultural asset will be the object of a small-scale rehabilitation project supported by a fundraising campaign through a crowdfunding platform. The centrality of people’s active participation will contribute to governance innovation by reverting to traditional top-down promotion processes and practices, in which heritage consumers represent passive recipients of ready-made offers and messages. The map platform also holds specific potential for cultural tourism purposes, avoiding mistakes in the geo-localization of sites.

Aquaculture is one of the fastest-growing segments of the food economy in modern times. It is also being considered as an important source of greenhouse gas (GHG) emissions. To date, limited studies have been conducted on GHG emissions from aquaculture system. In this study, daily addition of fish feed and soluble starch at a carbon-to-nitrogen (C/N) ratio of 16:1 (w/w) was used to examine the effects of carbohydrate addition on nitrogen transformations and GHG emissions in a zero-water exchange intensive aquaculture system. The addition of soluble starch stimulated heterotrophic bacterial growth and denitrification, which led to lower total ammonia nitrogen, nitrite and nitrate concentrations in aqueous phase. About 76.2% of the nitrogen output was emitted in the form of gaseous nitrogen (i.e., N2 and N2O) in the treatment tank (i.e., aquaculture tank with soluble starch addition), while gaseous nitrogen accounted for 33.3% of the nitrogen output in the control tank (i.e., aquaculture tank without soluble starch addition). Although soluble starch addition reduced daily N2O emissions by 83.4%, it resulted in an increase of daily carbon dioxide (CO2) emissions by 91.1%. Overall, starch addition did not contribute to controlling the GHG emissions from the aquaculture system. © 2013.

The increasing demand for protein from aquaculture will trigger a global expansion of the sector in coastal and offshore waters. While contributing to food security, potential conflicts with other traditional activities such as fisheries or tourism are inevitable, thus calling for decision-support tools to assess aquaculture planning scenarios in a multi-use context. Here we introduce the AquaSpace tool, one of the first Geographic Information System (GIS)-based planning tools empowering an integrated assessment and mapping of 30 indicators reflecting economic, environmental, inter-sectorial and socio-cultural risks and opportunities for proposed aquaculture systems in a marine environment. A bottom-up process consulting more than 350 stakeholders from 10 countries across southern and northern Europe enabled the direct consideration of stakeholder needs when developing the GIS AddIn. The AquaSpace tool is an open source product and builds in the prospective use of open source datasets at a European scale, hence aiming to improve reproducibility and collaboration in aquaculture science and research. Tool outputs comprise detailed reports and graphics allowing key stakeholders such as planners or licensing authorities to evaluate and communicate alternative planning scenarios and to take more informed decisions. With the help of the German North Sea case study we demonstrate here the tool application at multiple spatial scales with different aquaculture systems and under a range of space-related development constraints. The computation of these aquaculture planning scenarios and the assessment of their trade-offs showed that it is entirely possible to identify aquaculture sites, that correspondent to multifarious potential challenges, for instance by a low conflict potential, a low risk of disease spread, a comparable high economic profit and a low impact on touristic attractions. We believe that a transparent visualisation of risks and opportunities of aquaculture

In order to study the characteristic of nitrogen transport, the community structure and diversity of related microorganisms in aquaculture water of the Pearl River Delta. We established an artificial aquaculture ecosystem to study the microbial community of 15N-stable isotope probing (15N-SIP) labeled nitrogen transport microorganisms. The 15N-labeled DNA was separated by CsCl-ethidium bromide density gradient centrifugation, and was used to construct 16S rRNA gene clone libraries of bacteria and archaea. Phylogenetic analysis shows that 19 Operational Taxonomic Units (OTUs) from bacterial library were clustered in Proteobacteria and Planctomycetes. Proteobacteria (99.2%) was the dominant group, mainly consisted of Comamonas (15.7%), Nitrosomonas (12.4%), Enterobacteriaceae (11.5%) and Nitrobacter (11.5%). From archaeal library 9 OTUs were divided into 3 phyla: Thaumarchaeota, Crenarchaeota and Euryarchaeota. We successfully elucidated the microbial community of nitrogen transport microorganisms in aquaculture water of Pearl River Delta by using 15N-SIP. The data of the community will provide essential information for isolating nitrogen degrading microorganism, and provide scientific basis for creating a healthy aquaculture environment.

Full Text Available Conflicts and disputes among people are an integral part of everyday life, of our private and professional life. They can be of any kind, from social, commercial, family related disputes up to those between the states themselves. Just as the types and natures of disputes increase with the economic and cultural development of any society, the mechanisms of dealing with them take a special importance as well. Besides dispute resolution by state bodies that are established by law, alternative ways for resolving disputes are developing increasingly and are receiving a special importance as well. The alternative solution of a dispute is nothing more than an alternative for resolving the dispute outside the judicial system, where the main ways are mediation and arbitration. Alternative solutions to disputes are widespread in countries of common law systems, considering that most disputes are solved in this way. In this article we will examine mediation and its development especially in Albania. Mediation is a way to resolve disputes between two or more parties, where a third person, the mediator, negotiates with the parties so that they arrive at a solution acceptable to all.

2013-09-01

Aquaculture, the fastest growing food-producing sector, now accounts for nearly 50 % of the world's food fish (FAO in The state of world fisheries and aquaculture. FAO, Rome, 2010). The global aquaculture production of food fish reached 62.7 million tonnes in 2011 and is continuously increasing with an estimated production of food fish of 66.5 million tonnes in 2012 (a 9.4 % increase in 1 year, FAO, www.fao.org/fishery/topic/16140 ). Aquaculture is not only important for sustainable protein-based food fish production but also for the aquaculture industry and economy worldwide. Disease prevention is the key issue to maintain a sustainable development of aquaculture. Widespread use of antibiotics in aquaculture has led to the development of antibiotic-resistant bacteria and the accumulation of antibiotics in the environment, resulting in water and soil pollution. Thus, vaccination is the most effective and environmentally-friendly approach to combat diseases in aquaculture to manage fish health. Furthermore, when compared to >760 vaccines against human diseases, there are only about 30 fish vaccines commercially available, suggesting the urgent need for development and cost-effective production of fish vaccines for managing fish health, especially in the fast growing fish farming in Asia where profit is minimal and therefore given high priority. Plant genetic engineering has made significant contributions to production of biotech crops for food, feed, valuable recombinant proteins etc. in the past three decades. The use of plants for vaccine production offers several advantages such as low cost, safety and easy scaling up. To date a large number of plant-derived vaccines, antibodies and therapeutic proteins have been produced for human health, of which a few have been made commercially available. However, the development of animal vaccines in plants, especially fish vaccines by genetic engineering, has not yet been addressed. Therefore, there is a need to exploit

Aquaculture is an important source of atmospheric methane (CH4) and nitrous oxide (N2O), while few direct flux measurements are available for their regional and global source strength estimates. A parallel field experiment was performed to measure annual CH4 and N2O fluxes from rice paddies and rice paddy-converted inland crab-fish aquaculture wetlands in southeast China. Besides N2O fluxes dependent on water/sediment mineral N and CH4 fluxes related to water chemical oxygen demand, both CH4 and N2O fluxes from aquaculture were related to water/sediment temperature, sediment dissolved organic carbon, and water dissolved oxygen concentration. Annual CH4 and N2O fluxes from inland aquaculture averaged 0.37 mg m(-2) h(-1) and 48.1 μg m(-2) h(-1), yielding 32.57 kg ha(-1) and 2.69 kg N2O-N ha(-1), respectively. The conversion of rice paddies to aquaculture significantly reduced CH4 and N2O emissions by 48% and 56%, respectively. The emission factor for N2O was estimated to be 0.66% of total N input in the feed or 1.64 g N2O-N kg(-1) aquaculture production in aquaculture. The conversion of rice paddies to inland aquaculture would benefit for reconciling greenhouse gas mitigation and agricultural income increase as far as global warming potentials and net ecosystem economic profits are of concomitant concern. Some agricultural practices such as better aeration and feeding, and fallow season dredging would help to lower CH4 and N2O emissions from inland aquaculture. More field measurements from inland aquaculture are highly needed to gain an insight into national and global accounting of CH4 and N2O emissions.

1997-06-01

The number of viruses isolated from fish has grown in the last few years as a reflection of the increasing interest in fish diseases, particularly those occurring in aquaculture facilities. Of all the described viruses, only a few are considered to be of serious concern and economic importance; they are described in this review, drawing special attention to the four families of viruses (Birnaviridae, Rhabdoviridae, Iridoviridae and Reoviridae) that have been reported in Spanish aquaculture. Infectious pancreatic necrosis virus, a member of the first family, is the most spread virus with a prevalence of 39%. Viral diseases are untreatable and because effective and safe vaccines for fish are not yet commercially available, a great care needs to be exercised when moving fish or eggs from one site or country to another. Some fish health control regulations have been legislated in Europe and USA.

Kareem, R. O.; Williams, S. B.

2009-05-01

Fish supplies 25% of the total protein source in developing countries. A techno-economic analysis was performed for developing a good business proposal for aquaculture loans to enhance aquaculture development in Nigeria. A case study of catfish Clarias gariepinus framing was conducted in Abeokuta North Local Government of Ogun State, Nigeria. The results show that the fixed cost is N18 338 per year, and the variable cost is N459 700 per year, accounting for the largest amount of the total; therefore, a profit of N43 289 per month can be made. Sensitivity analysis was performed to assess any risk(s) that associated with unfavorable changes in government policy with particular reference to monetary policy. Positive net present value shows that the investment in fish farm is economically feasible and the net investment ratio is 3.52. Also, the benefit-cost ratio is 2.17. The internal rate of return (IRR) is 21% showing that the enterprise is able to offset the interest being charged on the loan. It is therefore worthwhile to invest into fish farm business in the study area. The study suggests that to better sustain the local aquaculture business, the government should create a good conducive environment to foster development of the fish farming. Government intervention is urgently needed to solve problems such as in traditional land tenure, grant credit facilities and subsidies, to enhance the aquacultural development in the country.

AQUACULTURE AS A MEXICAN STRATEGY FOR ECONOMIC DEVELOPMENT OF COASTAL AND RURAL AREAS

Directory of Open Access Journals (Sweden)

Antonio Mártir Mendoza

2006-09-01

Full Text Available SUMMARYAquaculture is one of the worldwide economic activities which has grown in the last 30 years at an annual rate of 9-10.0 %. Poultry, pork, lamb and beef meat production have increased only at an annual rate of 3.0 % in the same period, and in the last five years has decreased due to aviar fever and other viral difficulties. While aquaculture growth takes place in far away countries as China near by countries as Costa Rica, Honduras, Brazil and Chile keeps the same tendency. As far as Mexico´s aquaculture is concerned, it has grown steadily, missing, even its way out. On the one hand fish catches do not grow since the middle of the 80´s when fish production reached 1.5 million tones. On the other hand aquaculture in fresh waters and in sea waters are almost staging due to the loss of authority and governmental management capacity to make decisions. The recently elected federal government which will take office next December 1st, has on its hands the opportunity to favor aquaculture production and doing so, to develop Mexican coastal and rural areas.

Full Text Available Aiming at low automation degree and backward aquatic product management of current aquaculture in China, this paper designed a set of radio communication and control system which consists of 3 parts of information collection module, control module and radio communication module. This system both realizes wireless monitoring of quality parameters of water for aquaculture and realizes wireless control of water level and dissolved oxygen value through radio communication. Test results show that data transfer is more accurate and reliable after adding customized protocol and answer signals in radio communication. The highest error and missing rate within 1000 m is 0.36, the lowest error and missing rate is 0.05 and the longest response time is 49 ms. The dissolved oxygen value detection system designed in this paper is close to the testing value of existing dissolved oxygen value transmitter DO6309. With wireless data transfer mode, it has higher practicality. The wireless control of dissolved oxygen value and water level can be controlled within the appropriate range with stable and precise control. The study results can provide intelligent aquaculture model with simple operation and precise control for enormous aquatic breeders

Inland aquaculture ponds have been documented as important sources of atmospheric methane (CH4) and nitrous oxide (N2O), while their regional or global source strength remains unclear due to lack of direct flux measurements by covering more typical habitat-specific aquaculture environments. In this study, we compared the CH4 and N2O fluxes from rice paddies and nearby inland fish aquaculture wetlands that were converted from rice paddies in southeast China. Both CH4 and N2O fluxes were positively related to water temperature and sediment dissolved organic carbon, but negatively related to water dissolved oxygen concentration. More robust response of N2O fluxes to water mineral N was observed than to sediment mineral N. Annual CH4 and N2O fluxes from inland fish aquaculture averaged 0.51 mg m-2 h-1 and 54.78 μg m-2 h-1, amounting to 42.31 kg CH4 ha-1 and 2.99 kg N2O-N ha-1, respectively. The conversion of rice paddies to conventional fish aquaculture significantly reduced CH4 and N2O emissions by 23% and 66%, respectively. The emission factor for N2O was estimated to be 0.46% of total N input in the feed or 1.23 g N2O-N kg-1 aquaculture production. The estimate of sustained-flux global warming potential of annual CH4 and N2O emissions and the net economic profit suggested that such conversion of rice paddies to inland fish aquaculture would help to reconcile the dilemma for simultaneously achieving both low climatic impacts and high economic benefits in China. More solid direct field measurements from inland aquaculture are in urgent need to direct the overall budget of national or global CH4 and N2O fluxes.

Limits on testamentary freedom for people with dementia in Albania: Innovative Practice.

Science.gov (United States)

Vyshka, Gentian; Kruja, Jera

2017-07-01

The extent to which dementia affects a person's testamentary capacity has been the subject of much litigation with some countries introducing legal tests to assess capacity. In light of substantial societal change in Albania in the last two decades and an epidemic of property litigation, Albanian legal practice is witnessing an increasing number of attempts to posthumously nullify wills. Plaintiffs are mainly relatives of the deceased testator who are unhappy with the quantity or quality of the property they have inherited. Based on plaintiffs' claims, solicitors may request expert neuropsychiatric reviews postmortem, often basing their position on prescription drug use by the testator during his/her last years of life. The authors discuss ethical issues intrinsically related to the difficult role of a potential expert witness in these litigation cases.

Management of marine cage aquaculture. Environmental carrying capacity method based on dry feed conversion rate.

Science.gov (United States)

Cai, Huiwen; Sun, Yinglan

2007-11-01

Marine cage aquaculture produces a large amount of waste that is released directly into the environment. To effectively manage the mariculture environment, it is important to determine the carrying capacity of an aquaculture area. In many Asian countries trash fish is dominantly used in marine cage aquaculture, which contains more water than pellet feed. The traditional nutrient loading analysis is for pellet feed not for trash fish feed. So, a more critical analysis is necessary in trash fish feed culturing areas. Corresponding to FCR (feed conversion rate), dry feed conversion rate (DFCR) was used to analyze the nutrient loadings from marine cage aquaculture where trash fish is used. Based on the hydrodynamic model and the mass transport model in Xiangshan Harbor, the relationship between the water quality and the waste discharged from cage aquaculture has been determined. The environmental carrying capacity of the aquaculture sea area was calculated by applying the models noted above. Nitrogen and phosphorus are the water quality parameters considered in this study. The simulated results show that the maximum nitrogen and phosphorus concentrations were 0.216 mg/L and 0.039 mg/L, respectively. In most of the sea area, the nutrient concentrations were higher than the water quality standard. The calculated environmental carrying capacity of nitrogen and phosphorus in Xiangshan Harbor were 1,107.37 t/yr and 134.35 t/yr, respectively. The waste generated from cage culturing in 2000 has already exceeded the environmental carrying capacity. Unconsumed feed has been identified as the most important origin of all pollutants in cage culturing systems. It suggests the importance of increasing the feed utilization and improving the feed composition on the basis of nutrient requirement. For the sustainable development of the aquaculture industry, it is an effective management measure to keep the stocking density and pollution loadings below the environmental carrying

Full Text Available The private persons in any democratic state should have a right to dispute the administrative decisions affecting their rights, freedoms or interests before (among others competent independent courts. It is the key precondition for the principle of transparent and responsible public administration as an integral part of democratic governance. In addition to the “judiciary control of the administrative decisions”, the private persons` human rights against the public administration may be also protected through the Ombudsman office. The increasing importance of the afore mentioned issues relating public administration and the various types of control of the administrative acts been long time ago reflected in the mandate of almost all of the key international inter-governmental organizations, especially the European ones including the Council of Europe, the European Union and the OSCE. The establishment of both effective public administration and administrative justice system has been for a long period of time among the most “important and urgent” final strategic objectives of almost any country in the Balkans region, including Albania, Macedonia and Kosovo. This process included (among others establishing European-like Ombudsman offices in these countries. Against the above background the present paper firstly explains why the administration action must be controlled by the public, and it then outlines the European Right of Good Administration, the Ombudsman Office`s mandate. This is then followed by presenting the concept of European Administrative Space in terms of the Role of the OECD-SIGMA in Developing the Standards of Good Administration. Against the preceding sub-sections the paper further presents the basic legislative framework for action of the National Ombudsman Offices in Albania, Macedonia and Kosovo, which is then followed by a short review of the actual state of play of the Principle No.2 of the SIGMA European Principles for

Current status of viral diseases in Indian shrimp aquaculture.

Tandel, G M; John, K Riji; Rosalind George, M; Prince Jeyaseelan, M J

The intensification of aquaculture has been unique in showing the overwhelming changes in global food production in the last 100 years. Presently, it is playing a vital role in the economies of several countries. Conversely, it is also to be noted that the progression of aquaculture has been the foundation of anthropogenic alteration of a gigantic hierarchy and hence not astonishingly, it resulted in spread and emergence of an increasing group of new unknown diseases. In India, Penaeus monodon, black tiger shrimp was previously the foremost-cultivated shrimp species. Subsequently in 2008, the American white leg shrimp Litopenaeus vannamei has effectively replaced it. The change in dominant species has affected disease concerns in India as well as in world shrimp aquaculture. White spot syndrome virus (WSSV) is the most deleterious for both species. Hepatopancreatic parvovirus (HPV), Monodon baculovirus (MBV) and Infectious hypodermal and hematopoietic necrosis virus (IHHNV) are the other significant infectious agents of P. monodon and L. vannamei. An emerging disease of loose shell syndrome (LSS) was already reported from India during late 1998. A more recent disease of L. vannamei in India is monodon slow growth syndrome (MSGS), a component of which seems to be Laem-Singh virus (LSNV). Thus, most of the information in this review relates to new emerging pathogens that threaten the cultivation shrimp industry in India.

2007-04-01

Heavy metal contamination of soils causes serious problems to our society. A small number of interesting plant species have been identified that can grow in soils containing high levels of heavy metals, and can also accumulate these metals to high concentrations in the shoot. The heavy metal contents in root, shoot, leaves and flowers of spontaneous plants grown in metalliferous sites in Albania together with the elemental composition of the native soils were determined by X-ray fluorescence spectrometry. Efficiency of photosynthetic apparatus of analyzed ecotypes was evaluated via chlorophyll fluorescence imaging during induction kinetics. Response of plant root system to the presence of metals, the available pools of metals to plants, effect of plant biomass to phytoextraction, photosynthetic pigment metabolism and chlorophyll fluorescence signature of leaves allowed to characterize hyperaccumulator properties and to detect the variation between selected ecotypes to heavy metal accumulation.

2017-01-01

As aquaculture activity increases globally, understanding water mass characteristics of the aquaculture-wastewater plume, its nutrients, and its organic matter load and spatial distribution in the coastal recipient, is critical to develop a more sustainable aquaculture operation and to improve coastal management. We examined wastewater (estimated 42-48 m3 s-1) discharged from the largest aquaculture facility in the Red Sea and surveyed the area around the aquaculture outfall to characterize the biogeochemical properties of the wastewater plume and its spatial distribution. In addition, we assessed its associated microbial community structure. The plume was characterized by elevated levels of salinity, density, and turbidity, and traveled along paths determined by the bathymetry to form a dense, 1-3 m thick layer above the seafloor. The effluent was observed at least 3.8 km from the outfall throughout the year, but up to 8 km in early autumn. The total nitrogen concentration in the plume was more than 4 times higher than in surface waters 1.4 km from the outfall. High-throughput sequencing data revealed that bacterial and cyanobacterial communities significantly differed, and flow cytometry results showed that total cell counts were significantly higher at the outfall. Arcobacter, a genus associated with opportunistic pathogenic species (e.g. A. butzleri), was more abundant, while Prochlorococcus sp. was significantly less abundant at the outfall. This dense, bottom-flowing plume may have a detrimental impact on benthic and demersal communities.

There is some merit of thermal water from power plants in the effect to marine life. Since 1963, the research and development on the aquaculture using this warm water have been carried out at some twenty power plants, seven nuclear and thirteen thermal, some of which are now in the commercial stage. These fish farming projects are operated variously from seed to adult fish production. They can also be classified as land and sea facilities, conforming to the characteristics of the respective sea areas. The current situation in this field and the future prospect are described: thermal aquaculture including seed production and adult fish farming; the projects in nuclear and thermal power plants, respectively; future problems in the facilities, breeding environment and marine life for cultivation.

2016-05-01

Full Text Available Recent technological advances in marine shrimp and finfish aquaculture alleviate many of the environmental risks associated with traditional aquaculture, but challenges remain in cost-effective waste management. Liquid effluent from freshwater aquaculture systems has been shown to be effective in agricultural crop production (i.e., aquaponics, but few studies have explored the potential for reuse of marine aquaculture effluent, particularly the solid fraction. The purpose of this study was to investigate the use of marine aquaculture solid waste as a nutrient source for the nursery production of two salt tolerant plants commonly used in coastal salt marsh restoration, Spartina alterniflora (smooth cordgrass and Juncus roemerianus (black needlerush. Specifically, measurements of plant biomass and tissue nitrogen and phosphorus allocation were compared between plants fertilized with dried shrimp biofloc solids and unfertilized controls, as well as between plants fertilized with dried fish solids and unfertilized controls. In both experiments, S. alterniflora plants fertilized with marine aquaculture solids showed few significant differences from unfertilized controls, whereas fertilized J. roemerianus plants had significantly greater biomass and absorbed and incorporated more nutrients in plant tissue compared to unfertilized controls. These results suggest that J. roemerianus may be a suitable plant species for the remediation of marine aquaculture solid waste.

Impact of pond aquaculture effluents on seagrass performance in NE Hainan, tropical China

International Nuclear Information System (INIS)

Herbeck, Lucia S.; Sollich, Miriam; Unger, Daniela; Holmer, Marianne; Jennerjahn, Tim C.

2014-01-01

Highlights: • Seagrass performance in relation to large-scale pond aquaculture was assessed. • Effluent-affected seagrass meadows have a low biodiversity, shoot density and biomass. • Shading by epiphytes and sulphide poisoning are major decline mechanisms of seagrasses. • Distance to effluent source and pond agglomeration size are major determinants of seagrass degradation. - Abstract: The impact of pond aquaculture effluents on the distribution and performance of seagrasses was examined in NE Hainan, tropical China. Samples were taken along transects in three back-reef areas with different extent of aquaculture production in their hinterland. High δ 15 N in seagrass leaves and epiphytes (6–9‰) similar to values in pond effluents documented aquaculture as dominant nitrogen source in the back-reefs with decreasing impact with distance from shore. Seagrass species abundance, shoot density and biomass were lower and concentrations of nutrients, chlorophyll and suspended matter were higher at nearshore sites with high and moderate pond abundance than at the control site. High epiphyte loads and low δ 34 S in seagrass leaves suggest temporal shading and sulphide poisoning of the nearshore seagrasses. Observed gradients in environmental parameters and seagrass performance indicate that the distance from the pond outlets and size of the adjacent pond agglomeration are major determinants of seagrass degradation

Carbon sequestration capacity of sediments, algae, and zooplankton from fresh water aquaculture ponds.

2016-07-01

The contribution of aquaculture and allied activities to the emission of green house gases and consequently to global warming is an emerging concern among environmentalists in the recent past. However, there exists ample scope for aquaculture activities to sequester carbon and thus compensate for the carbon emissions linked to aquaculture. This article attempts to elucidate the carbon sequestration capacity of sediments, algae, and zooplankton from fresh water aquaculture ponds. The percent organic carbon in the pond sediments ranged from 0.39 to 1.31 with an average value of 0.912 ± 0.321 whereas the carbon sequestration capacity ranged from 0.442 to 1.882 MgC/ha (1 Mg = 10(6) g) with an average value of 1.018 ± 0.447 MgC/ha. In the case of zooplankton and algae from pond, the percent organic carbon was 7.688 ± 0.196 and 2.354 ± 0.047, respectively, whereas the total estimated carbon burial rate was 0.009 ± 0.005 and 0.150 ± 0.003 MgC/ha, respectively. These findings are discussed with the previous reports available at present and are found to be in comparable ranges.

Carbon dioxide stripping in aquaculture. part 1: terminology and reporting

Science.gov (United States)

Colt, John; Watten, Barnaby; Pfeiffer, Tim

2012-01-01

The removal of carbon dioxide gas in aquacultural systems is much more complex than for oxygen or nitrogen gas because of liquid reactions of carbon dioxide and their kinetics. Almost all published carbon dioxide removal information for aquaculture is based on the apparent removal value after the CO2(aq) + HOH ⇔ H2CO3 reaction has reached equilibrium. The true carbon dioxide removal is larger than the apparent value, especially for high alkalinities and seawater. For low alkalinity freshwaters (<2000 μeq/kg), the difference between the true and apparent removal is small and can be ignored for many applications. Analytical and reporting standards are recommended to improve our understanding of carbon dioxide removal.

2018-03-01

Due to their high-income contribution, seaweed and grouper aquacultures are important activities in Pulau Panjang community. Determining alternative strategies in developing sustainable aquaculture for seaweed and grouper and their priority factors from theses aquaculture activities are done using TOPSIS and AHP analysis. It was found that the development strategy that must be taken is the option to maintain aquaculture activities, while, environment factor is the highest priority to maintain seaweed and grouper aquaculture in Pulau Panjang. Then three priorities are obtained from environment factor. The first is to maintain the water quality by the growth requirements of seaweed and grouper by encouraging the formation of “Environmental Community Awareness” that involved the active participation of the community to maintain quality and carrying capacity of the environment. Second is to use of natural or artificial coastal protectors (soft structure). The third priority strategy is integration and real implementation of heavy metal pollution control between government, industry sector and society.

High Concentration of Red Clay as an Alternative for Antibiotics in Aquaculture.

Science.gov (United States)

Jung, Jaejoon; Jee, Seung Cheol; Sung, Jung-Suk; Park, Woojun

2016-01-01

The use of antibiotics in aquaculture raises environmental and food safety concerns because chronic exposure of an aquatic ecosystem to antibiotics can result in the spread of antibiotic resistance, bioaccumulation of antibiotics in the organisms, and transfer of antibiotics to humans. In an attempt to overcome these problems, high-concentration red clay was applied as an alternative antibiotic against the following common fish pathogens: Aeromonas salmonicida, Vibrio alginolyticus, and Streptococcus equinus. The growth of A. salmonicida and V. alginolyticus was retarded by red clay, whereas that of S. equinus was promoted. Phase contrast and scanning electron microscopy analyses confirmed the attachment of red clay on cell surfaces, resulting in rapid gravitational removal and cell surface damage in both A. salmonicida and V. alginolyticus, but not in S. equinus. Different cell wall properties of grampositive species may explain the unharmed cell surface of S. equinus. Significant levels of oxidative stress were generated in only the former two species, whereas significant changes in membrane permeability were found only in S. equinus, probably because of its physiological adaptation. The bacterial communities in water samples from Oncorhynchus mykiss aquacultures supplemented with red clay showed similar structure and diversity as those from oxytetracycline-treated water. Taken together, the antibiotic effects of high concentrations of red clay in aquaculture can be attributed to gravitational removal, cell surface damage, and oxidative stress production, and suggest that red clay may be used as an alternative for antibiotics in aquaculture.

In this contribution, we describe Isoperla vjosae sp. nov. from Albania. We characterize males, females, and larvae of the new species collected at the Vjosa River using morphological and molecular approaches. Isoperla vjosae sp.nov. is a member of the I. tripartita group, which is widely distributed in the Balkans. This new endemic species is being threatened by a proposed hydroelectric power dam on the Vjosa River impacting the type locality - a large, shifting gravel, low altitude River - an atypical habitat for larvae of the I. tripartita group. For the first time we use molecular tools to delineate Isoperla species from the Balkans.

The influence of finfish aquaculture on benthic fish and crustacean assemblages in Fitzgerald Bay, South Australia

Full Text Available The influence of sea-cage aquaculture on wildfish assemblages has received little attention outside of Europe. Sea-cage aquaculture of finfish is a major focus in South Australia, and while the main species farmed is southern bluefin tuna (Thunnus maccoyii, there is also an important yellowtail kingfish (Seriola lalandi industry. Yellowtail kingfish aquaculture did not appear to have any local or regional effects on demersal assemblages (primarily fish, but also some crustaceans surveyed by baited remote underwater video (BRUV in Fitzgerald Bay. We did, however, detect small scale spatial variations in assemblages within the bay. The type of bait used strongly influenced the assemblage recorded, with significantly greater numbers of fish attracted to deployments where sardines were used as the bait to compared to those with no bait. The pelleted feed used by the aquaculture industry was just as attractive as sardines at one site, and intermediate between sardines and no bait at the other. There was significant temporal variability in assemblages at both farm sites and one control site, while the second control site was temporally stable (over the 9 weeks of the study. Overall, the results suggested that aquaculture was having little if any impact on the abundance and assemblage structure of the demersal macrofauna in Fitzgerald Bay.

Does the Recent Growth of Aquaculture Create Antibiotic Resistance Threats Different from those Associated with Land Animal Production in Agriculture?

Science.gov (United States)

Done, Hansa Y; Venkatesan, Arjun K; Halden, Rolf U

2015-05-01

Important antibiotics in human medicine have been used for many decades in animal agriculture for growth promotion and disease treatment. Several publications have linked antibiotic resistance development and spread with animal production. Aquaculture, the newest and fastest growing food production sector, may promote similar or new resistance mechanisms. This review of 650+ papers from diverse sources examines parallels and differences between land-based agriculture of swine, beef, and poultry and aquaculture. Among three key findings was, first, that of 51 antibiotics commonly used in aquaculture and agriculture, 39 (or 76%) are also of importance in human medicine; furthermore, six classes of antibiotics commonly used in both agriculture and aquaculture are also included on the World Health Organization's (WHO) list of critically important/highly important/important antimicrobials. Second, various zoonotic pathogens isolated from meat and seafood were observed to feature resistance to multiple antibiotics on the WHO list, irrespective of their origin in either agriculture or aquaculture. Third, the data show that resistant bacteria isolated from both aquaculture and agriculture share the same resistance mechanisms, indicating that aquaculture is contributing to the same resistance issues established by terrestrial agriculture. More transparency in data collection and reporting is needed so the risks and benefits of antibiotic usage can be adequately assessed.

Bioethical Considerations of Advancing the Application of Marine Biotechnology and Aquaculture.

Harrell, Reginal M

2017-06-24

Fisheries and aquaculture make a crucial contribution to global food security, nutrition and livelihoods. However, the UN Sustainable Development Goals separate marine and terrestrial food production sectors and ecosystems. To sustainably meet increasing global demands for fish, the interlinkages among goals within and across fisheries, aquaculture and agriculture sectors must be recognized and addressed along with their changing nature. Here, we assess and highlight development challenges for fisheries-dependent countries based on analyses of interactions and trade-offs between goals focusing on food, biodiversity and climate change. We demonstrate that some countries are likely to face double jeopardies in both fisheries and agriculture sectors under climate change. The strategies to mitigate these risks will be context-dependent, and will need to directly address the trade-offs among Sustainable Development Goals, such as halting biodiversity loss and reducing poverty. Countries with low adaptive capacity but increasing demand for food require greater support and capacity building to transition towards reconciling trade-offs. Necessary actions are context-dependent and include effective governance, improved management and conservation, maximizing societal and environmental benefits from trade, increased equitability of distribution and innovation in food production, including continued development of low input and low impact aquaculture.

Full Text Available In this study various important indices were selected to assess the sustainable aquaculture strategies in rural areas of Iran. In addition the government officials, consultants and managers were surveyed to assess the indices of aquaculture development. The strengths, weaknesses, opportunities and threats   analyses were used to make a comprehensive evaluation on internal and external factors, participating the development of aquaculture strategies. The sum of the attractiveness scores from the Internal Factor Evaluation Matrix was approximately 2.55, being larger than 2.5, indicating that the strengths exceed the weaknesses. The sum of the External Factor Evaluation Matrix scores was 3.49, indicating that opportunities were higher than threats. This analysis showed that the development of aquaculture, promotion of new cold-water species production, productivity enhancement, establishment of hatchery facilities and formation of an effective support organization are the most important strategies that should be considered in the studied area. Results obtained on this research help decision makers on work of the aquaculture sector in rural areas of Iran.

Holographic Aquaculture

Proposed is an exploratory study to verify the feasibility of an inexpensive micro-climate control system for both marine and freshwater pond and tank aquaculture, offering good control over water temperature, incident light flux, and bandwidth, combined with good energy efficiency. The proposed control system utilizes some familiar components of passive solar design, together with a new holographic glazing system which is currently being developed by, and proprietary to Advanced Environmental Research Group (AERG). The use of solar algae ponds and tanks to warm and purify water for fish and attached macroscopic marine algae culture is an ancient and effective technique, but limited seasonally and geographically by the availability of sunlight. Holographic Diffracting Structures (HDSs) can be made which passively track, accept and/or reject sunlight from a wide range of altitude and azimuth angles, and redirect and distribute light energy as desired (either directly or indirectly over water surface in an enclosed, insulated structure), effectively increasing insolation values by accepting sunlight which would not otherwise enter the structure.

Full Text Available Information has become an important element without which society cannot achieve its objectives. The term “information society” is increasingly used nowadays, because of the importance and necessity of information in today's dynamic environment. Western countries are convinced that the information society will result in economic and social benefits (Audenhove 2000. Organization for Economic Cooperation and Development (OECD, notes that information infrastructures are expected to stimulate economic growth, increase productivity, create jobs, and improve on the quality of life (Gichoya 2005. It is for these reasons that many studies state that the role of ICTs as enablers of sustainable development is growing. The overall goal of this paper is to point out the importance of ICT market development for the sustainable development of all the economy and the final development of Information society, especially in developing countries, where Albania is the case study illustration. The first step of this research is to show the importance of studying ICTs in the light of building an information society. In fact, the efforts of a country to build an information society, in order to benefit in terms of sustainable development, are closely related to the efforts of building strong information infrastructures and a growing ICT sector. Many indicators related to Information society measurement deal in fact with the infrastructures needed and the products and services of ICT sector. But, failures to submit ICT in contexts which are contrary to techno-economic rationality are reflected in many cases in developing countries. Thus, a defining characteristic of this research is to understand the contexts that confront ICT and information systems development in developing countries in terms of their conditions. In fact the development of ICT sector, depend not only on the political, economic and social conditions of each country, but also on the phase of e

Concentrated turtle aquaculture effluent poses an environmental threat to water bodies, and therefore needs to be treated prior to disposal. This study was conducted to assess the effect of multi-soil-layer (MSL) systems treating turtle aquaculture effluent with adding different amounts of sludge. Four MSL systems were constructed with dry weight ratios of sludge with 0%, 5%, 10%, and 20% (MSL 1, MSL 2, MSL 3, and MSL 4, respectively). The turtle aquaculture effluent had an average chemical oxygen demand (COD), ammonia nitrogen (NH4(+)-N) and total nitrogen (TN) concentration of 288.4, 213.4, and 252.0 mg/L, respectively. The COD/TN (C/N) ratio was 1.2. The results showed that the four MSL systems could effectively treat the COD, NH4(+)-N, and TN, and MSL 4 showed significantly improved NH4(+)-N removal efficiency, suggesting the potential of sludge addition to improve the turtle aquaculture effluent treatment. The average COD, TN, and NH4(+)-N removal efficiencies of MSL 4 were 70.3%, 66.5%, and 72.7%, respectively. To further interpret the contribution of microorganisms to the removal, the microbial community compositions and diversities of the four MSL systems were measured. Comparisons of the denaturing gradient gel electrophoresis (DGGE) profiles revealed that the amount of nitrifying bacteria and diversity in MSL 4 were higher than those in the other three systems. We concluded that adding 20% of sludge improved the NH4(+)-N removal and stability of the system for nitrification, due to the enrichment of the nitrifying bacteria in MSL 4.

Current status of parasitic ciliates Chilodonella spp. (Phyllopharyngea: Chilodonellidae) in freshwater fish aquaculture.

Bastos Gomes, G; Jerry, D R; Miller, T L; Hutson, K S

2017-05-01

Freshwater fish farming contributes to more than two-thirds of global aquaculture production. Parasitic ciliates are one of the largest causes of production loss in freshwater farmed fishes, with species from the genus Chilodonella being particularly problematic. While Chilodonella spp. include 'free-living' fauna, some species are involved in mortality events of fish, particularly in high-density aquaculture. Indeed, chilodonellosis causes major productivity losses in over 16 species of farmed freshwater fishes in more than 14 countries. Traditionally, Chilodonella species are identified based on morphological features; however, the genus comprises yet uncharacterized cryptic species, which indicates the necessity for molecular diagnostic methods. This review synthesizes current knowledge on the biology, ecology and geographic distribution of harmful Chilodonella spp. and examines pathological signs, diagnostic methods and treatments. Recent advances in molecular diagnostics and the ability to culture Chilodonella spp. in vitro will enable the development of preventative management practices and sustained freshwater fish aquaculture production. © 2016 John Wiley & Sons Ltd.

Genetic manipulations in aquaculture: a review of stock improvement by classical and modern technologies.

Science.gov (United States)

Hulata, G

2001-01-01

The aim of this review was to highlight the extent to which the genetic technologies are implemented by the aquaculture industry. The review shows that some of the modern genetic technologies are already extensively applied by the diverse aquaculture industries, though not to the same extent for all important aquacultured species (according to FAO 1998 figures). Some species (common carp, Atlantic salmon, rainbow trout, channel catfish, Nile tilapia, and the Pacific oyster) received concentrated breeding efforts, while other major cultured species (Chinese and Indian carps and the giant tiger shrimp) received, so far, relatively limited attention, and a few species (Yesso scallop, blue mussel, white Amur bream, and milkfish) have, apparently, not been genetically improved at all. Most of the genetically improved strains reaching the aquaculture industry were developed through traditional selective breeding (selection, crossbreeding, and hybridization). Emerging, more modern technologies for genetic manipulation seem to take 10-20 years from being established experimentally until applications affect the industry. Thus, chromosome-set and sex manipulations started to affect the industry during the 1980's and 1990's. DNA marker technology and gene manipulations have yet hardly affected the industry. The former have not matured yet, but hold much promise. The latter could have affected the industry already had it not been restricted by public concern.

Efficiency of Different Integrated Agriculture Aquaculture Systems in the Red River Delta of Vietnam

Directory of Open Access Journals (Sweden)

Nguyen Van Huong

2018-02-01

Full Text Available Integrated Agriculture Aquaculture (IAA is characteristic with diversity of small-scale production systems in the Red River Delta, Vietnam where most integrated aquaculture systems are closely associated to the VAC model, an ecosystem production that three components: garden (V, pond (A and livestock pen (C are integrated. These VAC systems effectively use all the available land, air, water and solar energy resources, and also effectively recycle by-products and waste for providing diversified agricultural products to meet the complex nutritional demands of rural communities. The IAA systems are dynamic, diverse and subject to economic and environmental changes. By investigating 167 aquaculture households, the traditional VAC, New VAC, Animal Fish (AF and Commercial Fish (FS systems are identified as four existing IAA systems. This paper presents the main characteristics and economic efficiency of these IAA systems. The study’s results indicate clear evidence that the traditional VAC system and New VAC system are the most efficient and effective models. The findings of this study have shed light on the important role of integrated aquaculture systems to food security and economic development of households and local communities. The VAC systems are likely to propose for improving household food security and developing the local economy.

Full Text Available The internet of things technology (IoT is growing very rapidly. IoT implementation has been conducted in several sectors. One of them is for aquaculture. For the traditional farmers, they face problems for monitoring water quality and the way to increase the quality of the water quickly and efficiently. This paper presents a real-time monitoring and controlling system for aquaculture based on If This Then That (IFTTT model and cloud integration. This system was composed of smart sensor module which supports modularity, smart aeration system for controlling system, local network system, cloud computing system and client visualization data. In order to monitor the water condition, we collect the data from smart sensor module. Smart sensor module consists of sensor dissolved oxygen, potential of hydrogen, water temperature and water level. The components of smart aeration system are microcontroller NodeMCU v3, relay, power supply, and propeller that can produce oxygen. The system could set the IFTTT rules for the ideal water condition for the pond in any kinds of aquaculture based on its needs through the web and android application. The experimental result shows that use IFTTT model makes the aquaculture monitoring system more customizable, expandable and dynamic.

Growth-Climate Response of Young Turkey Oak (Quercus cerris L. Coppice Forest Stands along Longitudinal Gradient in Albania

Merita Stafasani

2015-06-01

Full Text Available Background and Purpose: Turkey oak (Quercus cerris L. is the most widespread species in Albania and less investigated from dendroclimatological point of view. Previous studies have reported that Q. cerris is sensitive to the environment when growing at different latitudes and ecological conditions. Based on this fact we have explored the response of different Q. cerris populations located along the longitudinal gradient. Materials and Methods: The stem discs were sampled from six sites (Kukes, Diber, Rreshen, Ulez, Elbasan, Belsh along longitudinal gradient ranging from north-east to central Albania. All oak forests stands grow under the influence of specific local Mediterranean climate. Tree-ring widths were measured to the nearest 0.001 mm using a linear table, LINTAB and the TSAP-Win program. Following the standard dendrochronological procedures residual tree-ring width chronologies were built for each site. Statistical parameters commonly used in dendrochronology were calculated for each site chronology. Relations between the tree-ring chronologies were explored using Hierarchical Factor Classification (HFC and Principal Component Analysis (PCA, while the radial growth-climate relationship was analyzed through correlation analysis using a 19-month window from April in the year prior to tree-ring formation (year t - 1 until October in the year of growth (year t. Results and Conclusions: The length of the site chronologies ranged from 16 to 36 years, with the Elbasan site chronology being the longest and the Belsh site chronology the shortest one. Trees at lower elevation were younger than trees at higher elevation. Statistical parameters (mean sensitivity (MS and auto correlation (AC of site chronologies were different among them and lower values of AC1 showed a weaker dependence of radial growth from climatic conditions of the previous growing year. Principal component analysis showed that Belsh, Rreshen and Elbasan site chronologies were

Full Text Available We investigate some characteristics of foreshock activity of moderate and large earthquakes which occurred in the present century in Albania and the surrounding area. Using a prediction algorithm, based on possible foreshocks, we obtained a probabilistic relation between possible foreshocks and mainshocks. From documentary and instrumental data for the period 1901-1994 for the area between 39.0°- 43.0°N and 18.5°-21.5°E we evaluated the probability of the occurrence of mainshocks immediately after their possible foreshocks. The result shows that the probability that mainshocks with magnitude M ³ 6.0 are preceded by a foreshock with magnitude M ³ 4.4, distance £ about 50 km and time £ 10 days is 38% (6/16. The probability that one earthquake with M ³ 4.4 will be followed by a larger earthquake with M ³ 6.0 within about 50 km and 10 days is 1.3% (6/468, but the probability increases to 33% (1/3 if 7 earthquakes with M ³ 4.4 occur within about 50 km and 10 days. From instrumental data for the period 1971-1994, the probability that mainshocks with M ³ 5.0 are preceded by a foreshock with magnitude M ³ 4.0 is 33% (5/15. The probability that one earthquake with M ³ 4.0 will be followed by a larger earthquake with M ³ 5.0 within about 50 km and 10 days is 1.9% (5/262, but the probability increase to 5.6% (1/18 if 3 earthquakes with M ³ 4.0 occur within about 50 km and 10 days. We also found a regional variation of foreshock activity with activity decreasing from the Vlora-Elbasani-Dibra transversal seismic belt to the Ionian-Adriatic seismic zone to the interior part of Albania seismic zone.

Analysis of economic and energy utilization aspects for waste heat aquaculture

Energy Technology Data Exchange (ETDEWEB)

Olszewski, M.; Wilson, J. V.

1978-01-01

A waste heat aquaculture system using extensive culture techniques to produce fin and shellfish is currently under investigation at the Oak Ridge National Laboratory. The system uses nutrients in waste water streams to grow algae and zooplankton which are fed to fish and clams. A tilapia polyculture association and the freshwater clam Corbicula are the animals cultured in the system. The investigations were performed to determine the economic feasibility of the system and examine energy utilization in the system. A net energy analysis was performed to identify the energy saving potential for the system. This analysis includes all energy costs (both direct and indirect) associated with building and operating the system. The results of the economic study indicated that fish production costs of $0.55/kg ($0.25/lb) were possible. This cost, however, depends upon the fish production rate and food conversion efficiency and could rise to as much as $1.65/kg ($0.75/lb). Clam production costs were found to be in the neighborhood of $0.37/kg of clam meat ($1.24/bushel). The energy utilization study results indicated that, when all energy costs are included, fish from the aquaculture system may require only 35% of the net energy now required for fish products from the ocean. However, the energy requirements also depend on system parameters and could be as large as the energy required for ocean caught products. Clams can be produced in the aquaculture system using only about 25% of the net energy required by traditional means. The results of the analysis indicate that the system appears to be economically feasible. They also indicate that significant energy savings are possible if waste heat aquaculture products replace ocean caught products.
