Synopsis (short abstract) This paper is the first report of a project to produce better awareness and utilization of Sri Lanka’s demersal or bottom-dwelling fish resources. It describes the rationale, the mechanics and the findings of experiments conducted toward this end between October 1979 and March 1980. Specifically, the experiments were meant to ascertain the suitability of a well-known system of demersal fishery — bottom-set longlining — for Sri Lanka, and to investigate ways of advancing this fishery. The pa per may be useful for fisheries planners and officials who are concerned with increasing fish supplies and for fisheries researchers concerned with new and better fishing methods. It may also serve as a guide for eventual extension if the experiments yield conclusive results. The experiments in demersal fishing are an activity of the Bay of Bengal Programme for the Development of Small-Scale Fisheries, GCP/RAS/040/SWE, in which the Ministry of Fisheries, Sri Lanka, is the cooperating agen cy. The Programme provided a fishing technologist, Mr. G. Pajot, to supervise theactivity and a consultant masterfisherman, Mr. H. H. Juliusson, to conduct fishing trials. The Ministry of Fisheries provided the services of a technical liaison officer, Mr. K. T. Weerasooriya, and a research assistant, Mr. S. S. C. Pieris. Other agencies involved in the project included Lion Trawlers Industries Limited (a private company that provided the boat and the crew used for the experiments); the Ceylo n Fisheries Corporation (CFC), which supplied frozen bait to be used with the bottom longlines; and the Ceylon Fisheries Harbour Corporation (CFHC) which processed fresh bait given by the CFC.

    Further Fishing Trials With Bottom-Set Longlines In Sri Lanka - BOBP/WP/16 1982
    Also available in:
    No results found.
    The trials of bottom-set longlining off Sri Lanka are an activity of the Bay of Bengal Programme (BOBP) for the Development of Small-Scale Fisheries, GCP/RAS/040/SWE. The work was carried out by the Research Division of the Ministry of Fisheries with technical guidance and assistance from the BOBP, which included the services of a fishing technologist (Mr. G. Pajot), a biologist consultant (Dr. G. H. P. De Bruin) and the Project Officer (Mr. B. W. Perera). The Ministry of Fisheries provided the services of a research officer, Mr. K. T. Weerasooriya, and other research staff. Messrs Samalanka provided a consultant master fisherman (Mr. Sandvik) and fishing gear and equipment for monofilament longline trials. Several boat owners cooperated by providing boats and crews.

    Promotion Of Bottom Set Longlining In Sri Lanka - BOBP/WP/40 1985
    Also available in:
    No results found.
    This document is the third report of bottom set longlining trials conducted by BOBP in cooperation with the Ministry of Fisheries, Sri Lanka. The two earlier reports covered trials off the south west coast of Sri Lanka between October 1979 and March 1980 (BOBP/WP/6) and on the east and west coasts of Sri Lanka during August 1980 - July 1981 (BOBP/WP/16). This report summarizes the results of the trials conducted between 1981 and 1983 and also discusses biological information obtained from the tr ials during the period 1979 - 82. The report concludes that bottom longlining might be a viable alternative fishery for both the 28-footers and the 18’ GRP boats during the lean season for driftnet fisheries. This conclusion is based on trials conducted in Negombo, 1981 /82 and Puduwakattuwa, Dehiwala, Panadura and Ratmalana, 1982/83. This report, and the trials on which it is based, are activities of the small-scale fisheries project of the Bay of Bengal Programme (BOBP). It began in 1979 and covers five countries bordering the Bay of Bengal — Bangladesh, India, Malaysia, Sri Lanka and Thailand. Funded by SIDA (Swedish International Development Authority) and executed by the FAO (Food and Agriculture Organization of the United Nations), the project seeks to develop, demonstrate and promote appropriate technologies and methodologies to improve the conditions of small-scale fisherfolk and the supply of fish from the small-scale sector in the member countries.

    Fishing Trials With High-Opening Bottom Trawls In Palk Bay, Tamil Nadu - BOBP/WP/10 1980
    Also available in:
    No results found.
    This document is the first report of fishing trials held with high-opening bottom trawls in Palk Bay, off Mandapam in Tamil Nadu, India, during March-July 1980. The trials were conducted jointly by the Bay of Bengal Programme and the Government of Tamil Nadu. The main objective of the trials was to as certain the technical and economic feasibility of using high-opening bottom trawls to tap demersal and pelagic stocks of food fish in the Palk Bay areas, and to train local counterparts in the desi gn, construction and use of these trawls. The Bay of Bengal Programme provided a consultant masterfisherman, Mr. John Crockett, to conduct the trials, under the supervision of Mr. G. Pajot, fishing technologist. On behalf of the Tamil Nadu Government, Mr. S. Pandurangan and Mr. P. V. Ramamurthy served as counterparts.
