ProjectBiosocioeconomics of Fishing for Small Pelagics along The Southwest Coast of Sri Lanka - BOBP/WP/96 1994
Also available in:
No results found.The marine fishery in Sri Lanka is the country’s major source of animal protein supply (60%). It also provides employment to around 100,000 fishermen. More than 90 per cent of the fish production comes from the coastal area extending up to about 25 nautical miles from the shore. A group of small pelagic species constitutes more than 45 per cent of this catch. Before the motorization of fishing craft in the early 1950s, almost the entire production of small pelagics came from the beach seine (B S). After motorization, however, small-mesh gillnets (GN) became popular. With the introduction of synthetic material, the gilinet became the major gear. In the early 1980s, fishermen on the southwest coast of Sri Lanka started using the purse seine (PS) to target small pelagic resources. The rapid increase in fishing intensity due to motorization gave rise to several fishing disputes. The use of the more efficient purse seine in the southwestern coastal waters led to several conflicts. In 198 7, the Ministry of Fisheries and Aquatic Resources (MFAR) framed regulations limiting the area of operation of the PS. However, enforcement of these regulations was not successful. The MFAR thereupon, realized the need to examine the possible interaction between the different fisheries in terms of resources and income distribution among various user-groups. It was expected that the information obtained through a study would assist in arriving at sound management measures. The study was undertake n by the Department of Fisheries and Aquatic Resources and the National Aquatic Resources Agency (NARA) with guidance from the Bay of Bengal Programme’s biosocioeconomics team. The reporting was funded by the United Nations Development Programme (UNDP). -
ProjectReview Of Experiences With And Present Knowledge About Fish Aggregating Devices - BOBP/WP/23 1983
Also available in:
No results found.A review of experiences worldwide and of present knowledge about fish aggregating devices (FADs) was carried out by the BOBP during 1981. Nearly 150 institutions and experts were requested to contribute. This paper draws on these replies as also on other published material. The paper describes a spectrum of FADs ranging from very simple and cheap traditional applications for nearshore waters to modern, highly sophisticated and expensive products for off-shore aggregation of tunas and tuna-l ike fishes. Some of the experimental designs described here are worth considering for indicative fishing trials. The preparation of this paper is an activity of the Bay of Bengal Programme for Small-Scale Fisheries Development, referred to in brief as BOBP. The BOBP is funded by the Swedish International Development Authority (SIDA) and the United Nations Development Programme (UNDP) and executed by the Food and Agriculture Organisation of the United Nations. Countries bordering the Ba y of Bengal are members of the Programme. Its main aims are to develop, demonstrate and promote methodologies to improve the conditions of smallscale fisherfolk and to assess and monitor fishery resources. -
ProjectBiosocioeconomic 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.
