    Small Offshore Fishing Boats in Sri Lanka - BOBP/REP/61 1993
    Also available in:
    No results found.

    The Bay of Bengal Programme (BOBP) was invited in the early Eighties by the Shri Lankan Ministry of Fisheries to evaluate the offshore fisheries and the fishing craft being used in it. The evaluation was done by a consultant, O Gulbrandsen, Naval Architect. Subsequent to this evaluation, BOBP helped to develop and introduce two small multiday offshore fishing boats, the SRL-34 and the SRL-15. When Shri Lankan fishermen began fishing further offshore, more and more boats began to disappear a t sea. The BOBP was requested to provide assistance for studying the reasons for the disappearances and to help in making recommendations for the development of search-and-rescue facilities for the island’s fishermen. A consultant (U Hallberg) studied the facilities available and prepared a report which was submitted to the Ministry of Fisheries. Similarly, another consultant (E Dahle) studied the safety aspects of boat construction and prepared a draft of regulations for consideration by the Mi nistry. This report summarizes BOBP’s assistance provided in offshore fishing boat development and related safety-at-sea aspects. The work started under the SIDA funded project “Development of Small-scale Fisheries” GCP/RAS/040/SWE and was concluded under “Small-scale Fisherfolk Communities” GCP/RAS/l18/MUL funded jointly by DANIDA and SIDA.

    Biosocioeconomic Assessment of the Effects of Fish Aggregating Devices in the Tuna Fishery in the Maldives - BOBP/WP/95 1994
    Also available in:
    No results found.

    Fish Aggregating Devices (FADs) have proved very successful in the Maldives, where there is a countrywide FAD installation programme by the Ministry of Fisheries and Agriculture (MOFA) underway. The main reason for the success of FADs in the Maldives is their applicability to the existing fisheries. With the motorization of the fishing fleet, the efficiency and range of operation of the fleet has increased. FADs help not only to reduce searching time and fuel costs, but they also considerabl y increase production. Although the aggregation of fish around FADs has been demonstrated successfully, and the merits of FAD-fishing proven, data on the cost-effectiveness of FADs are still lacking. MOFA, with the assistance of the Bay of Bengal Programme’s (BOBP) regional ‘Bioeconomics’ project (RAS/91/006), therefore, undertook to assess and quantify the impact of FADs in tuna fishing. The project installed two FADs in two separate areas in the Maldives and closely studied the biological, e conomic and sociological effects of them on the fisheries and on the island communities in the two areas. The effectiveness of the two FADs was measured by comparing data collected one year before and one year after their installation. The results of the study are presented in this paper. The study was funded by the United Nations Development Programme (UNDP).

    Improvement of Large-Mesh Driftnets for Small-Scale Fisheries in Sri Lanka - BOBP/WP/3 1980
    Also available in:
    No results found.

    Large-mesh driftnets play a pivotal role in Sri Lankas small-scale fisheries. They captured about 25% of all the fish Sri Lanka produced in 1978. In view of the rising cost of these widely used nets, a nine-month experimental project was conducted in 1979 on making the nets less costly and more productive. Under the project, fishermen-cum-boat-owners in two fishing centres-Beruwala and Velvettiturai- used two kinds of nets: traditional nets and the modified nets supplied by the Bay of Benga l Programme. Comparative data on fish catch by species and weight for the two kinds of nets revealed that nylon nets of finer yarn-which are 25% cheaper than the traditional nets-raised the fish catch by 20 to 30 per cent during the experiments. The other conclusions resulting from the experiments concern the ropes and floats used for driftnets. Polypropylene ropes and large cylindrical auxiliary surface floats are as good as —and cheaper than the nylon ropes and small longitudinal floats u sed at present with largemesh driftnets. Following from the above, the main recommendation is that the use of thinner nylon netting material, of polypropylene ropes and of large floats should be energetically promoted. Their manufacture and import should be encouraged.
