Abstract

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 in the area between 1984 and 1986. The model estimated that the average trophic level of the trawl fishery catch was 2.7 in these years.
