Trophic model of the coastal fisheries ecosystem of the west coast of peninsular Malaysia

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.

Strategic review of the fishery situation in Thailand

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.

Socioeconomic assessment of marine fisheries of Thailand

Thailand is currently one of the ten largest fishing nations in the world. In 1996, fish production reached 3.7 million t with 90% of the production coming from the marine fisheries sector and 10% from inland fisheries. Thai fishing operates in four fishing grounds namely, the Gulf of Thailand, the Andaman Sea, the South China Sea and the Bay of Bengal. However with the establishment of the Exclusive Economic Zone (EEZ) in 1977, Thailand lost over 300 000 km2 of traditional fishing grounds.

A socioeconomic and bioeconomic analysis of coastal fisheries of Bangladesh

Bangladesh has an exclusive economic zone (EEZ) of 164 000 km2 and a continental shelf area of 66 440 km2. Artisanal (small scale) fisheries extend from the coast to 40 m while industrial (commercial scale) fisheries operate beyond 40 m depth. The coastal fisheries of Bangladesh exploit a complex multi-species resource. There are 18 demersal and pelagic species, seven species of larger pelagic and 10 shrimp species that are commercially important among the fishes exploited.

Small-scale aquaculture: Global and national perspectives

Fish has been a staple food for over a billion people. Its demand is increasing due to growing population and awareness about health benefits of aquatic animal food. Disappointingly, wild catch worldwide is on the decline and aquaculture is emerging as the only solution. It grew at 9%/yr in the last 10 years becoming the fastest growing food production sector. At present, aquaculture produces only about 45 million t per year but it needs to be doubled by 2030 to meet its growing demand. Asia produces over 85% of the global farmed fish - mostly by small-scale farmers.

Shrimp processing in Bangladesh

The shrimp industry in Bangladesh is the major fisheries foreign exchange earner. The various processing industries consist of freezing plants, smoking/drying factories and meal factories. Details are given of the freezing plants ofBangladesh, quality control laboratories and smoking factories, and also the various shrimp products produced. Suggestions are made for improved production.

Review of the history, status and prospects of the black tiger shrimp (Penaeus monodon) hatchery sector in Bangladesh

Culture of shrimp, mainly Penaeus monodon, makes an important contribution to Bangladesh's aquaculture industry. Shrimp hatcheries are the foundation on which the shrimp industry is built. Hatchery performance and management therefore has extremely important implications for the long-term viability of the entire shrimp sector, especially given its vulnerability to diseases such as white spot syndrome virus (WSSV).

Reduction in effort and favorable environment helped to increase shrimp catch in Kuwait

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.
