The objectives of this study were first, to understand the market chain of fish as traded by women in the south-eastern Arm of Lake Malawi, with a specific focus on analyzing how fish is moved from the lake to the wholesale market. Secondly, the study identifies HIV/AIDS vulnerability factors along this market chain i.e. from the point of catch to the wholesale market.
Twenty-five species of fish, shrimp and prawn from local markets in Bangladesh were analysed for concentrations of total Fe, haem Fe and non-haem Fe by ICP-MS. Total Fe and non-haem Fe concentrations were measured in nitric acid-digested samples and haem Fe was extracted using acidified 80% acetone for 60 min. Total Fe concentrations ranged from 0.55 to 14.43 mg/100 g FW, and haem Fe% ranged from 18 to 93% of total Fe. Repeat extractions with 80% acetone recovered additional haem Fe, suggesting that previous measurement by this technique may have underestimated haem Fe content.
Up-to-date evidence on levels and trends for age-sex-specific all-cause and cause-specific mortality is essential for the formation of global, regional, and national health policies. In the Global Burden of Disease Study 2013 (GBD 2013) we estimated yearly deaths for 188 countries between 1990, and 2013. We used the results to assess whether there is epidemiological convergence across countries.
The literature focuses on mortality among children younger than 5 years. Comparable information on nonfatal health outcomes among these children and the fatal and nonfatal burden of diseases and injuries among older children and adolescents is scarce. This study is to determine levels and trends in the fatal and nonfatal burden of diseases and injuries among younger children (aged <5 years), older children (aged 5-9 years), and adolescents (aged 10-19 years) between 1990 and 2013 in 188 countries from the Global Burden of Disease (GBD) 2013 study.
This paper provides an overview of the live reef fish market in Hong Kong, which accounted for about 15,000 t/yr (US$345 million) of live fish imports in the mid-1990s. The live fish trade has spawned a number of management concerns, including overfishing of highly-valued species, use of destructive fishing techniques and human health risks. Recent actions by the Hong Kong government in response to these concerns are reported and possible region-wide initiatives are briefly discussed in this paper.
The quantitative genetic basis of fatty acid composition was examined in the Genetically Improved Farmed Tilapia (GIFT) strain of Nile tilapia selected for high breeding value for body weight and in the contemporaneous control selected for average breeding value. Gas chromatography analysis of 514 frozen fillet samples, obtained from the offspring of 104 sires and 154 dams from two generations in 2006 and 2007, showed that the fish possess all important fatty acids (FA), with the amount of omega-3 polyunsaturated fatty acids being 3.6%.
Aquaculture has become the fastest growing sector of food production in the world. Despite the encouraging trends, several constraints have a negative impact on the growth of aquaculture. Among those, diseases are the primary limiting factors. Bacterial diseases are responsible for heavy mortality in both wild and cultured fish. Antibiotics are used to control such infection but may result in development and spread of antimicrobial-resistant bacteria and resistance genes and occurrence of antimicrobial residues in fish tissues.
This study, which aims at analyzing the nutritional value of fish products sold on the fish markets of Lubumbashi, has been conducted by the World Fish center as part of its regional programme "Fisheries and HIV/AIDS in Africa : investing in sustainable solutions". This report contains a map of fish markets of Lubumbashi with analyses of fish species found at these markets, and information about the most common fish species.
Rural households who fail to gain a voice in decisions over the management of shared forests, pasturelands, wetlands and fisheries face heightened risks to their livelihoods, particularly as competition increases between existing and new user groups. Exclusion from decision-making increases vulnerability of rural households, making it more difficult for them to move out of poverty and thwarting broader efforts to achieve sustainable resource management. Poor rural women in particular often face institutionalized barriers to effective participation in resource management.
