Synopsis (short abstract) Between 1980 and 1985, the small-scale fisheries project of the Bay of Bengal Programme (BOBP) demonstrated fishing techniques with various types of highopening bottom trawls in Tamil Nadu and Orissa, in cooperation with the fisheries departments of these states. New deck equipment and machinery and simple trawl rigging accessories for standard Indian coastal trawlers were also locally developed, demonstrated and introduced. In Gujarat, training and experimental fishing in high-opening bott om trawling were conducted early 1983 by CIFNET (Central Institute of Fisheries Nautical and Engineering Training). BOBP provided technical and material support to the Cl FN ET effort. It was hoped that high-opening bottom trawls would help relieve fishing pressure on prawn resources, put idle prawn trawlers to gainful use during the off season and help tap underexploited food fish resources. The innovations with deck equipment and gear accessories were intended to make trawling effort safe r, more efficient and more comfortable. This paper summarizes the results of the high-opening bottom trawl demonstrations and the response to them in the three states. It also sums up the impact of trawling effort following BOBP demonstrations on fishery resources; and discusses the present status of gear designs and of deck equipment. Future prospects concerning high-opening bottom trawling are also discussed.

    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.

    Fishing Trials With High-Opening Bottom Trawls From Chandipur, Orissa, India - BOBP/WP/48 1986
    Also available in:
    No results found.
    This paper reports on the findings of fishing trials with one-boat bottom trawls conducted from Chandipur, in Balasore district, Orissa, in 1984/85. Detailed specifications and designs of some of the trawls are given. Trials during 65 fishing days clearly demonstrated the superiority of the high opening bottom trawls over the conventional bottom shrimp trawl. The trials were conducted along commercial lines employing private trawlers. The cooperating agency in Orissa was the Directorate of Fisheries. The Orissa fishing trials were part of a wider project organized jointly by the small-scale fisheries project of the Bay of Bengal Programme (BOBP) and the Government of India for developing and introducing high-opening bottom trawling for food fish and shrimp. Two earlier working papers (BOB P/WP/10 and BOBP/WP/20) document trials conducted in Tamil Nadu, while one other paper (BOBP/WP/21) suggests improvements to the deck machinery and layout of small coastal trawlers.

    Further Trials Of Mechanised Trawling For Food Fish In Tamil Nadu - BOBP/WP/20 1982
    Also available in:
    No results found.
    This document describes the aims, scope and results of experiments conducted with high-opening bottom trawls in Palk Bay and Gulf of Mannar, and off the Coromandel Coast, from July 1980 to May 1981 (An earlier paper, BOBP/WP/1O, described experiments conducted during March-July 1980). The experiments were carried out jointly by the FAO/SIDA Bay of Bengal Programme and the Directorate of Fisheries, Tamil Nadu. The BOBP provided the services of a fishing technologist, G. Pajot, and a consulta nt master fisherman, John Crockett. On behalf of the Government of Tamil Nadu, two officials - S. Pandurangan and P. V. Ramamoorthy - served as counterparts. The BOBP is a regional fisheries programme executed by the Food and Agriculture Organization of the United Nations (FAO) and funded by the Swedish International Authority. It covers five countries bordering the Bay of Bengal — Bangladesh, India, Malaysia, Sri Lanka and Thailand. Its main aims are 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 sector in the five member countries.
