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.
This essay told the story of a Bangladesh woman in using integrated small-scale aquaculture technology on her small plot of pond in improving her family's livelihoods.
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.
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.
Introduction of red claw crayfish (Cherax quadricarinatus) in Ecuador is presented together with the status and future of crayfish culture in the country.
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.
The article is a summary of the preliminary results of an AFSSRN-funded study on Risk Programming of Rice-Fish Production Systems in the Philippines conducted early 1993 by the AFSSRN-CLSU team. The results show that rice-fish culture leads to a higher rice production compared to rice monoculture.
Currently there are 2 sources of freshwater prawn Macrobrachium rosenbergii production in Vietnam - natural production from the rivers and canals and aquaculture production from ponds and ricefields. An account is given of the production of this prawn in the Mekong Delta. The prawns are harvested primarily by a common small scale method using shelter traps.
This paper details some of the problems encountered in culturing black tiger shrimp (Penaeus monodon) the semi-intensive way in India, which include aquatic macrophytes; invasions by molluscs, jellyfish and frogs; predators; fouling organisms; and others.
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.
