Fish Catch Assessment of Maljhee-Kangsa Floodplain in Bangladesh

N. Ahmed, M.M. Rahman and M.M. Rahman

Abstract

A study was conducted to assess fish catch in the Baila beel of Maljhee-Kangsa floodplain in the north-central part of Bangladesh. A total of 7 types of fishing gear were found in use by the fishermen which are: push net, gill net, cast net, lift net, current net, fish traps and hooks. The duration of fishing depends on use of fishing gear, season, habitat type, water depth and abundance of fishes. From the survey it was found that the highest average fishing time was estimated in fish trap (18.04 h/day) and the lowest in push net (3.21 h/day). There are variations in the Catch Per Unit of Effort (CPUE) of different gears in different seasons. The highest and the lowest CPUE were recorded in current net and hook which were 0.31 and 0.02 kg/gear/h, respectively. According to the fishermen, the highest catch was obtained during the receding of floodwater in post-monsoon season (October-December) and the lowest during the pre-monsoon season (April-June). A total of 39 fish species were identified in the catches of different gears. From the survey it was found that a fisherman daily catches an average 1.43 kg of fish. Alarmingly, the catch of fish has declined by an estimated 20% in the past five years. Concerns arise about the sustainable catches due to over fishing and indiscriminate use of gears. It is therefore necessary to provide institutional and organisational supports for artificial stocking and establishing fish sanctuaries through active community participation for sustainable catches.
