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.
Small indigenous fish species (SIS) are an important source of essential macro- and micronutrients that can play an important role in the elimination of malnutrition and micronutrient deficiencies in the populations of many South and Southeast Asian countries. Of the 260 freshwater fish species in Bangladesh, more than 140 are classified as SIS and are an integral part of the rural Bangladeshi diet. As many SIS are eaten whole, with organs and bones, they contain high amounts of vitamins and minerals, including calcium, and iron and zinc. Some SIS, such as mola, are also rich in vitamin A.
Under the Regional Programme Fisheries and HIV/AIDS in Africa, implemented by the WorldFish Center in collaboration with FAO, this paper is the second in a series of papers that have been generated from reviewing literature on trends in consumption and processing of low-value fish products marketed in the Lake Victoria region. The papers fall under the programme’s research component in Uganda, analyzing nutritive quality and post-harvest activities in ‘low value’ fish market chains around Lake Victoria, focusing on Mukono District, Uganda.
Analysis from research and practice in Africa shows that fishing communities are hardly reached by HIV-related services, education, and business services, partly because of the efforts and costs involved and a lack of good practice in reaching out to these often remote areas. At the same time, fish traders, especially women, travel regularly to remote fishing camps to purchase fish. Although female fish traders may be exposed to HIV, violence and abuse in their interactions and relationships with fishermen, economic necessity keeps them in this trade.
This study was planned to determine the grazing rate of O. niloticus from both toxic and non toxic strains of Microcystis aeruginosa with its effect on fish health through study of some clinical signs, hematological and biochemical parameters.
Nearly 500 million people in the developing world depend on aquatic agricultural systems for their livelihoods, with 140 million of these people living in poverty. Occurring along freshwater floodplains and coastal deltas, aquatic agricultural systems are highly productive farming and fishing systems that provide multiple opportunities for growing or harvesting food and generating income.
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 work is part of the Regional Programme Fisheries and HIV/AIDS in Africa: Investing in Sustainable Solutions, implemented by the WorldFish Center and funded by the Swedish International Development Cooperation Agency (Sida) and the Norwegian Ministry of Foreign Affairs. The research study analyses the effects of a fish supplemented diet on HIV/AIDS patients’ response to Anti Retroviral Treatment (ART).
The WorldFish Center and the UN FAO are currently implementing a regional programme entitled Fisheries and HIV/AIDS in Africa: investing in sustainable solutions. The programme, funded by SIDA and the Norwegian Ministry of Foreign Affairs, aims to strengthen regional capacity to develop sustainable solutions to enhance the contributions of fish and fisheries to development. In particular, the programme is building a strategic response to HIV/AIDS in the fisheries sector that will benefit vulnerable groups in wider society.
