Abstract
The present investigation was conducted from May to December 2005 at Kumira, the representative area of Chittagong coast for bio-socioeconomic analysis of ESBN fishery. In catch composition of Kumira, it was observed that finfish occupied 77.03 %, shrimp 19.82 % and crab 3.15 % and the average catch per boat per day were found 16.6 kg in Kumira. The highest total catch per boat per day (50 kg) was found in October at Kumira. The lowest catch was found (2 kg) in August at Kumira. The average total catch per landing center per month was found 14805 kg at Kumira. The average catch per fishermen per day was found 3.39 kg at Kumira and the average cost per boat per month was about 7,813 Tk in the study area. Average sale per month was found over 18,713 Tk in Kumira. During the month July and August most of the fishermen were engaged in Hilsa fishing with the Hilsa gill net resulting the total catch was with ESBN lowest in those months.Asian J. Med. Biol. Res.

Highlights
Bangladesh is endowed with vast inland and marine water resources where large numbers of fishermen are engaged in fishing
Biological data collection started from January to December, 2005; it included catch and species composition and prices of the various commercial fishes collected by Estuarine Setbagnet (ESBN)
The average catch composition of Bombay duck (Harpodon neherius) was found highest in the present investigation followed by Shrimp
Summary
Bangladesh is endowed with vast inland and marine water resources where large numbers of fishermen are engaged in fishing. One single operation of any type of fishing gear in any fishing area brings in a number of species of varies sizes and ages. It has the complexity of multi-gear fisheries system making the situation further complex for management and conservation of the resources for sustainable use. Bangladesh has a coastline of 480 km along the North and North-East part of the Bay of Bengal It has an internal estuarine water area of 7,325 sq. Nautical miles up to 10 fathom depth baseline, territorial waters of 2,640 sq. It has an internal estuarine water area of 7,325 sq. nautical miles up to 10 fathom depth baseline, territorial waters of 2,640 sq. nautical miles from the baseline, EEZ of 41,040 sq. nautical miles and the continental shelf of 2,480 sq. nautical miles
