The biomass of 40 ecological groups, the diet composition of prey and predators, production/biomass (P/B) and consumption/biomass (Q/B) ratios, and catches were used as basic input to parameterize an Ecopath model of the Gulf of Thailand. Following construction of a mass-balance ecosystem model,...

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...

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...

The 1995 trawl data of the research vessels Pramong 2 and 9 in the Gulf of Thailand were analyzed using TWINSPAN and DCA. Four main station clusters were identified related to geographic location and depth. Two clusters are associated with shallow water areas and the other two clusters are found...

A mass-balance steady-state trophic model of the coastal fisheries ecosystem off the West Coasts of Sabah and Sarawak, Malaysia (10 - 60 m depth) was constructed using the Ecopath software. The ecosystem models were partitioned into 29 ecological/trophic groups. The input values (e.g. biomasses)...

A mass-balance model of the trophic structure of San Pedro Bay, Leyte Province, Philippines was constructed using the Ecopath modeling software. The model is composed of 16 ecological groups (13 consumer, 2 producers, 1 detritus groups). The input parameters were obtained from the resource...

Trawl survey data collected by the RV Mutiara 4 in 1979 off the north coast of Central Java (Indonesia) were used to examine the composition and distribution of species assemblages in the area. Classification (TWINSPAN) and ordination (DCA) techniques commonly used in community structure...

A trophic model of the coastal ecosystem in the waters of Bangladesh, Bay of Bengal (from the shoreline to 150 m depth) is presented. The model consists of 15 ecological groups. The biomasses of the groups (particularly the demersal species) were estimated from demersal trawl surveys conducted...

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...
