Descripción
Concerned about the effects of the estuarine set bagnet fishery on the shrimp and finfish resources and also on other marine fisheries dependent on the same resources, the Bangladesh Department of Fisheries, with the assistance of the Bay of Bengal Programme (BOBP), conducted a two-year (1989-91) biosocioeconomic assessment of the estuarine set bagnet fishery. In ordcr to make the assessments needed for management purposes, it was necessary to gather information on other interactive fisheries: t he marine set bagnet, trammelnet, bottom longline and shrimp trawl fisheries. The only major marine fishery not included was the Hilsa fishery, which does not interact with the estuarine set bagnet fishery. This report contains the information (catch rate, seasonality, catch, effort, biological parameters and cost and earnings) gathered in the estuarine set bagnet and other interactive fisheries, but the socioeconomic information and biosocioeconomic assessment results are published separate ly as BOBP/WP/90 and BOBP/REP/62. The authors of the seven parts of this paper were all members of the Management and Development Project, Department of Fisheries, Chittagong, Bangladesh, and were assisted by BOBP’s Senior Fishery Biologist, Dr K Sivasubramaniam. The investigations were done under BOBP’s “Small-scale Fisherfolk Communities” project funded by DANIDA and SIDA and the reporting under “Bioeconomics of Smallscale Fisheries” funded by UNDP.
