Small-mesh driftnets account for about one-third of the total marine catch of Bangladesh. This paper reports on the execution and the findings of experiments to improve the small-mesh driftnet fishery in Bangladesh. They were conducted between April 1981 and February 1982 by the project for small-scale fisheries development of the Bay of Bengal Programme (BOBP), in cooperation with the Marine Fisheries Department of the Bangladesh Government and CARITAS, a social service agency. The trials were part of a project to improve fishing gear and methods in Bangladesh. Other project activities include trawling, large-mesh driftnets, set bagnets and longlining. The BOBP seeks to improve the conditions of small-scale fisherfolk and to assess and monitor fishery resources in the Bay of Bengal region. The FAO is the executing agency, while SIDA (Swedish International Development Authority) and UNDP (United Nations Development Programme) are the funding agencies. |
