The WorldFish Center is implementing the FtF Aquaculture Project in 20 southern districts in Bangladesh. The project is implemented under USAID’s Feed the Future initiative in collaboration with the Government of Bangladesh.
A preliminary mass-balance trophic model was constructed for the coastal fisheries ecosystem of the West Coast of Peninsular Malaysia (0 - 120 m depth). The ecosystem was partitioned into 15 trophic groups, and biomasses for selected groups were obtained from research (trawl) surveys conducted in the area in 1987 and 1991. Trophic interactions of the groups are presented. The network analysis indicates that fishing fleets for demersal fishes and prawns have a major direct or indirect impact on most high-trophic level groups in the ecosystem.
Fisheries are an important source of animal protein for most of Thailand’s population, particularly in provinces on or near the coast. Between 1978 and 1997 the per capita consumption of fish averaged 24 kg·capita-1 annually. In 1995, about 535 210 people were involved in the fisheries sector and 44% of these were engaged in small scale marine capture fisheries. Since 1982, Thailand has faced problems with the development of marine capture fisheries and their over-exploitation which has increased fishery conflicts and disputes with neighboring countries.
Relative biomass per recruit of adult (i.e. sexually mature) fin to shellfish is shown to help in identifying levels of fishing mortality likely to lead to recruitment overfishing. This is illustrated with data from a Malaysian penaeid shrimp fishery.
Indonesia’s fisheries exports rose from 2 206 t in 1970 to 598 385 t in 1996 with a subsequent export value rise from US$0.69 billion to US$1.78 billion. The surplus in the balance of trade (BOT) was US$1.59 billion in 1996. The fisheries exports were predominantly shrimp, tuna, skipjack and demersal fishes. Large scale fisheries operations are prevalent in the Java Sea. The dominant fishing gear is hook-and-line (40%), gillnet (31%), traps (10%), seine net and lift-net (6%), purse seine (1%), shrimp net with BED (0.04%) and others (6%). The large scale fisheries e.g.
It is time to recognize the crucial role of small-scale farmers in Asian aquaculture production and trade. The socially and economically important smallscale sector – the “mainstay” of Asian aquaculture – is innovative, but faced with constraints in modern markets. The sector needs investment from public and private sectors to compete and thrive. Another challenge is to develop certification programs in ways that promote responsible aquaculture expansion with due consideration to small-scale farming.
This chapter mainly presents the history of shrimp aquaculture in Bangladesh and impacts of shrimp farming on rural livelihoods with particular focus on income and dietary consumption, based on literature reviews and structured field surveys. The chapter also focuses on the complexities of land use patterns and recommends a holistic approach to adopt integrated zoning principles into national policies to sustain shrimp farming in Bangladesh.
Fisheries are an important source of protein and employment for Sri Lanka’s population. The declaration of the Exclusive Economic Zone (EEZ) in 1976 gave the country a water area larger than its land area. The coastal fisheries resources consist of small and large pelagic fish, demersal and coral reef fish, invertebrates, shrimps and crabs. The small pelagic fish contribute 70% of the catch from coastal waters with an estimated annual production of 152 752 t in 1997.
The 1988-1989 shrimp catch from kuwait waters was 5125 t, representing a 62% increase above the previous record of 3158 t in 1966-1967. Ninety-eight per cent of the record landing was comprised of Penaeus semisulcatus (Penaeidae). The attainment of optimal spawning-stock biomass by reduction in effort, protection of small recruits through delayed season opening, as well as strict enforcement of closed nursery areas, and occurrence of two strong recruitment pulses due to favorable environmental conditions in 1988 appear to be the major reasons for the increase.
This paper presents the results of analyses of the demersal fish assemblages in Bangladesh waters of the Bay of Bengal. Catch data from three trawl survey cruises from January to February 1985 covering 135 stations were utilized for community structure analysis using TWINSPAN and DCA techniques. Both techniques separated the deepwater stations (> 90 m) from the shallow areas (< 90 m).
