Synopsis (short abstract) This paper describes the conduct and the findings of a pilot survey of the set bagnet fishery of Bangladesh which is believed to account for at least one third of the total catch from the marine small-scale fisheries. The survey was planned by the BOBP’s project officer in Bangladesh and executed by the staff of the Marine Fisheries Department, Chittagong, with the department’s statistics officer as the team leader. He was assisted by three inspectors of fisheries. Between January and June 19 83, when the survey was conducted, a total of 172 fishermen and bahardars all along the coast and at Dubla Char, Sonar Char and Sonadia Island, were interviewed. The survey was by no means exhaustive, but it is hoped that it will throw some light on the present status of a traditional fishery which will continue to play an important role. The survey was an activity of the small-scale fisheries project of the Bay of Bengal Programme. The project began in 1979 from Madras. It is funded by SI DA (Swedish International Development Authority), and executed by the FAO (Food and Agriculture Organization of the United Nations). Countries bordering the Bay of Bengal — Bangladesh, India, Malaysia, Sri Lanka and Thailand are members of the project. Its main aims are to develop, demonstrate and promote appropriate technologies and methodologies to improve the conditions of small-scale fisherfolk in member countries.

    Pilot Survey Of Driftnet Fisheries In Bangladesh - BOBP/WP/15 1982
    Also available in:

    Two hundred and eighty fishing units were interviewed for this survey. Conducted during February and March 1981, the interviews sought details about fishing operations and fish landings. The work covered the two main categories of drift-net - 31/2 – 41/2 inch and 71/2 – 81/2 inch stretched mesh respectively - at three major landing sites. It was found that the productivity, expressed in terms of catch weight per fishing day or as catch value per day of trip duration at that time was consid erably lower for large-mesh units than for small-mesh units, It was also found that the average length of net used by large-mesh boats (around 1300 m) was considerably less than that for small-mesh boats (1800-2200m). There was no difference in the number of crew on board: between 7 and 10 per boat, in both categories. Averages for times spent running to and from fishing grounds, and for times actually spent fishing, were established. In this respect the units may be considered very efficient-ve ry little time was wasted. The catch weight per km net and fishing day may have varied more with the fishing area than with the category of net used. Differences in value of catch per km net resulted not so much from differences in catch composition between units and categories of units as from other factors such as length of net deployed, skill of crew etc. The survey contains suggestions as to how similar surveys could be designed and carried out in the future.

    Biosocioeconomic Assessment of the Effect of the Estuarine Set Bagnet on the Marine Fisheries of Bangladesh - BOBP/WP/94 1994
    Also available in:

    The estuarine set bagnet (ESBN) fishery of Bangladesh is one of the country’s niost important traditional fisheries and a large population of small-scale fisherfolk have been dependent on it for a long time. In the last two decades, the introduction and rapid expansion of the bottom trawl fishery and of shrimp culture have contributed to problems of interaction and competition among the fisheries which exploit the same penaeid shrimp and demersal finfish stocks. The traditional, but less effic ient, ESBN fishery has not only become vulnerable, being likely to be affected by other fisheries, but may also be destructive to small penaeid shrimp and some of the finfish resources that these other fisheries exploit. The Department of Fisheries, Bangladesh, decided to investigate this issue and the Bay of Bengal Programme (BOBP) was requested to assist. The study was funded by the United Nations Development Programme (UNDP). Bioeconomic and socioeconomic surveys were undertaken in 1989/90 an d a National Seminar was held in January 1992 to discuss the results. Because of the interactive nature of many of the marine fisheries, it was necessary, for the assessment and management of any one fishery, to consider the other fisheries exploiting the same resources. Therefore, in addition to the estuarine set bagnet fishery, the fisheries employing marine set bagnets (MSBN), trammelnets (TRN), beach seines (BS), bottom longlines (BLL) and trawlnets (TWL), as well as shrimp fry-collection using pushnets (PN) and dragnets (DN), were investigated. These studies have been documented separately in BOBP working papers BOBP/WP/89 Studies of Interactive Marine Fisheries of Bangladesh and BOBP/WP/90 — The Socioeconomic Condition of the Estuarine Set Bagnet Fisherfolk in Bangladesh. The present paper is based on the results and findings of these publications and assesses the biosocioeconomic impact of the ESBN fishery on the other marine fisheries of Bangladesh. The working papers mention ed provide additional information on the respective fisheries.

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

    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).
