    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.

    Technical Trials of Beachcraft Prototypes in India - BOBP/WP/7 1980
    Also available in:
    No results found.

    This is the first report of technical trials conducted in India of four beachcraft prototypes designed for India’s east coastfisheries. The trials were held in May-June 1980 in Ennore, 20 kilometres north of Madras, under the auspices of the Bay of Bengal Programme, in cooperation with the Governments of Tamil Nadu and Andhra Pradesh. The report briefly discusses the limitations of traditional craft operating on India’s surf-beaten east coast and the desirability of developing new types of craft with greater carrying capacity and productivity. It discusses the additional considerations — as regards such matters as the shape of the boat, the construction material, the systems of surf-crossing and beachianding —that must weigh in the design of surfboats. It describes in words and pictures the four prototypes tested in Ennore, the conduct of the trials and the findings they yielded. The trials covered only surf-crossing and beachlanding. Of the four prototypes, two — considered the most promising — were selected for intensive fishing trials. The report sets down the relative merits of the four prototypes. The report may serve to keep governments, development agencies and boatbuilders informed about the progress of development of beachcraft. It may also be of interest to small-scale fisheries planners in general. The prototypes were built at Aquamarine (P) Limited, Madras; Indian Seacraft, Madras, and the Andhra Pradesh Fisheries Corporation Boatyard at Kakina da. Diesel engines were supplied by Greaves Lombardini Limited, Madras.

    Trials In Bangladesh Of Large-Mesh Driftnets Of Light Construction - BOBP/WP/12 1981
    Also available in:
    No results found.

    This document is the second report of a fishing gear improvement project in Bangladesh. It describes the rationale, the mechanics and the findings of experiments with large-mesh driftnets of thin twine conducted near Chittagong from October 1980 to February 1981. The experiments were carried out in cooperation with the Kalidaha Fishing Projectof CARITAS, a social service agency. In a parallel activity, experimental thin-twine large-mesh driftnets were also tried out by private fishermen in commercial fishing operations along with their own traditional fishing gear. The experiments yielded the finding that driftnets of thinner twine, which are about 40% cheaper than the traditional nets, also catch more fish than the traditional nets. Experiments were also carried out by BOBP with driftnets of different mesh sizes in cooperation with the Kalidaha Fishing Project. Here the conclusion was that large-mesh sizes are more effective than the smaller. The Ministry of Fisher ies and Livestock, Bangladesh, participated in the fishing gear improvement project as a cooperating agency. The project is an activity of the Programme for the Development of Small-Scale Fisheries in the Bay of Bengal, referred to in brief as the Bay of Bengal Programme. This is a regional FAO programme that seeks to develop and demonstrate appropriate technologies and methodologies in many areas of small-scale fisheries such as fishing craft, fishing gear, fishing methods and utilization and c oastal aquaculture. The Programmes goals are to improve the conditions of small-scale fisherfolk and the supply of fish from the small-scale sector in five countries that border the Bay of Bengal — Bangladesh, India, Malaysia, Sri Lanka and Thailand.
