    Biosocioeconomics of Fishing for Shrimp in Kuala Sepetang, Malaysia-BOBP/WP/98 1994
    Also available in:
    No results found.

    The shrimp fishery is one of the most important components of the marine capture fishery along the west coast of Peninsular Malaysia. Although the percentage of shrimp by weight in the total landings in this area is not high, shrimp are important to the capture fishery due to their high value. Kuala Sepetang, in the district of Larut-Matang, is one of the main shrimp landing centres in Perak. In 1992, a research project to assess the biosocioeconomics of the shrimp fishery in this area was imple mented jointly by the Department of Fisheries, Malaysia, and the Bay of Bengal Programme (BOBP). The project involved biological and socioeconomic data-collection for a period of one year. The reporting was funded by the United Nations Development Programme. The main objectives of this project were to analyze the relative perfomances of the different shrimp fishing gear, assess their biosocioeconomics and suggest optimum levels of exploitation of the resource. The findings of the project, it is hoped, will be useful in formulating future policy guidelines and management measures with regard to the exploitation of the limited shrimp resources. The methodologies used in this project will also help to improve the capabilities of national staff in future biosocioeconomic assessments.

    The Effect of Artificial Reef Installation on the Biosocioeconomics of Small-Scale Fisheries in Ranong Province, Thailand-BOBP/WP/97 1994
    Also available in:
    No results found.

    The Government of Thailand felt that installation of suitable Artificial Reefs (ARs) in the coastal waters around the country would contribute towards management of coastal fisheries resources, restrict operation of such efficient methods as trawling in the coastal waters, reduce conflicts among fishermen, and increase opportunities for small-scale fisherfolk to improve their income from fishing. In 1989, ARs were installed in three locations in Ranong Province. The three Ars covered an area o f 50.8 km2, about 9-11 km from the shoreline and at depths ranging from 12 to 17m. The Bay of Bengal Programme (BOBP), within the framework of its project RAS/9J/006, Biosocioeconomics of Small-scale Fisheries, agreed to support the implementation of a subproject that would take up as a case study and assess the impact of the ARs by applying biosocioeconomic analytic methods. The investigations between 1991 and 1993 were done under BOBP’s ‘Small-scale Fisherfolk Communities’ project funded by DANIDA and SIDA and the reporting under ‘Bioeconomics of Small-scale Fisheries’ funded by UNDP. This document is a compilation of working documents describing the separate but simultaneously carried out investigations into the suitability of the locations, the environmental conditions around the ARs, colonization of the ARs, enhancement of the resources, the influence of the ARs on the fisheries, and the impact of income changes, if any, on the socioeconomic conditions of the small-scale fish erfolk fishing at the ARs.

    Biosocioeconomic Assessment of the Effect of the Estuarine Set Bagnet on the Marine Fisheries of Bangladesh - BOBP/WP/94 1994
    Also available in:
    No results found.

    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.
