Sandfish hatchery techniques

Sandfish is arguably the most commercially valuable of the tropical species of sea cucumber that are processed into bêche-de-mer. It is widely distributed throughout the Indo-Pacific, occurring in shallow inshore areas where it is easily accessible to coastal fishers. A-grade bêche-de-mer processed from sandfish commands some of the highest prices on the international market. But these same attributes also make it vulnerable to overexploitation. Sadly, this has happened in most places where it occurs.

Role of tilapia (Oreochromis andersonii) in integrated farming systems in Zambia.

The old system of cultivating several species of tilapia together in the same pond has been changed to monospecies culture. Oreochromis andersonii has been shown to yield good growth and production rates. A broodstock (Kafue strain) of the species was introduced into the Chilanga Fish Farm and separate ponds for the production of fry, fingerlings and market-size fish have been maintained. Integrated fish farming using fish-cum-pig and fish-cum-duck combinations has given very good production results.

Report of the first policy advisory group meeting of the regional programme "Fisheries and HIV/AIDS: Investing in sustaining solution"

The WorldFish Center and the UN Food and Agriculture Organization (FAO) are currently implementing a Regional Programme entitled Fisheries and HIV/AIDS in Africa: Investing in Sustainable Solutions, to strengthen the capacity in the region to develop sustainable solutions to enhance the contributions of fish and fisheries to economic and human development. In particular, the programme is building a strategic response to HIV/AIDS in the fisheries sector that will generate benefits for vulnerable groups in wider society.

Progress report of aquaculture technology transfer through NGOs and feedback to research program fro the period Aug 1992-Jun 1994

The Fisheries Research Institute with the technical assistance of International Center for Living Aquatic Resources Management (ICLARM) has developed low-cost aquaculture practices, through on-station and on-farm research. These studies have shown that farmer's fish productions and incomes could be increased manifold, through appropriate management practices.

Probiotics and aquaculture

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.
