    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.

    The Socioeconomic Condition of The Estuarine Set Bagnet Fisherfolk in Bangladesh - BOBP/WP/90 1993

    This working paper describes the socioeconomic survey of selected estuarine set bagnet (ESBN) fishing villages in Bangladesh. It deals with village profiles, households and population structured according to sex, age and education. The households have been stratified according to income-generating activities and income. Fishing households were stratified even further on the basis of the craft and gear combinations owned, owned and operated, or operated only and their income estimated on a monthl y basis. Variations in income within the community of ESBN fishermen and relative income from different sources are also discussed with opportunities for generating income from sources other than the ESBN fishery. The survey was based on a sampling of six villages, each one identified in each of the six strata into which the estuarine areas of Bangladesh was divided. This survey was conducted to obtain baseline socioeconomic parameters that are relevant to the management of the ESBN fisherie s and forms the input, along with the information on their fisheries interacting with it (BOBP/WP/89), for the ‘Biosocioeconomic assessment of the impact of estuarine set bagnet fisheries on other marine fisheries in Bangladesh’ (BOBP/REP/62).

    The Coastal Set Bagnet Fishery of Bangladesh - Fishing Trials and Investigations - BOBP/REP/34 1986

    This paper reports on the conduct and findings of fishing experiments during six seasons (1980-86) to improve the economics of set bagnets (behundi jal) in Bangladesh. The main purposes were to reduce the costs by using cheaper materials and to increase productivity by employing nets of larger size and new designs. The set bagnet is a traditional fishing gear widely used in the coastal area of Bangladesh. It is the second most important fishing gear after gillnets. In order to better estim ate its importance, BOBP also conducted a pilot survey, the outcome of which has been published in a separate paper (BOBP/WP/34). The work was carried out in cooperation with the Marine Fisheries Department (MFD), Chittagong. The principal national officer engaged in the work was Mr. M.A. Sabur, Fisheries Inspector, who participated on a full-time basis in the trials during the last four years. The initial experiments (1980-81) were conducted in cooperation with the Kalidaha Fishing Pr oject of CARITAS, a social service agency of Juldia near Chittagong, and with private fishermen at Dubla Char off the Sunderbans. From the 1981/82 season the trials were concentrated in Sonadia Island, just north of Cox’s Bazaar. They were conducted in cooperation with private fishermen. Overall planning and supervision of the work was provided by BOBP’s Fishing Technologist, Mr. G. Pajot, during 1980-82 and 1984-86 and by Mr. T. Gestsson, consultant, during 1982-84 The author participate d part-time in the 1983/84 and 1984/85 trials as BOBP Associate Expert in Fishing Technology and in the 1985/86 trials as full-time consultant. Dr. B.T. Antony Raja, Fishery Biologist and BOBP consultant, assisted in interpreting data collected during the last season (1985/86) and in preparing this report.
