Synopsis (short abstract) A review of experiences worldwide and of present knowledge about fish aggregating devices (FADs) was carried out by the BOBP during 1981. Nearly 150 institutions and experts were requested to contribute. This paper draws on these replies as also on other published material. The paper describes a spectrum of FADs ranging from very simple and cheap traditional applications for nearshore waters to modern, highly sophisticated and expensive products for off-shore aggregation of tunas and tuna-l ike fishes. Some of the experimental designs described here are worth considering for indicative fishing trials. The preparation of this paper is an activity of the Bay of Bengal Programme for Small-Scale Fisheries Development, referred to in brief as BOBP. The BOBP is funded by the Swedish International Development Authority (SIDA) and the United Nations Development Programme (UNDP) and executed by the Food and Agriculture Organisation of the United Nations. Countries bordering the Ba y of Bengal are members of the Programme. Its main aims are to develop, demonstrate and promote methodologies to improve the conditions of smallscale fisherfolk and to assess and monitor fishery resources.

    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).

    Hauling Devices For Beachlanding Craft - BOBP/WP/51 1986
    Also available in:
    No results found.
    This paper describes mechanical hauling devices for beachcraft developed and tested by the small-scale fisheries project of the Bay of Bengal Programme (BOBP) in India and Sri Lanka. The paper records the project’s experiences with beach-hauling devices from 1980 till 1985. A diesel engine-driven winch capable of hauling boats up to a weight of about 1500 kg was introduced and is now manufactured commercially. A problem that still awaits solution is that of suitable rollers underneath the hull t o reduce friction drag. The trials have shown that for larger craft and rough conditions, more complicated multi-speed winches are required. Besides the authors, those who took part in the work included Mr. Oyvind Gulbrandsen, Naval Architect (Consultant), who designed and tested the manually operated capstan; Mr. R. Ravikumar, Naval Architect; Mr. S.O. Johansen, BOBP Naval Architect (Associate Professional Officer); Mr. S.B. Sarma, Inspector of Fisheries, Andhra Pradesh; and Mr. E. Sriniva san, Inspector of Fisheries, Tamil Nadu Numerous fishermen also participated in the trials. The work on beachhauling devices, and this paper describing the work, were sponsored by the small-scale fisheries project of the BOBP.

    Current Knowledge of Fisheries Resources in the Shelf Area of the Bay of Bengal - BOBP/WP/8 1980
    Also available in:
    No results found.
    This paper summarises published knowledge of theexploited and exploitable fishery resources in the shelf area of the Bay of Bengal. It also offers some general remarks about the potential for fisheries development in some areas of the region and the need for management measures in other areas; the types of resources studies that need to be carried out; and the availability of information. The author of the paper is Dr. B. T. Antony Raja, Deputy Commissioner, Fisheries Division, Ministry of Agriculture, Department of Agriculture and Cooperation, New Delhi, India, who served as a consultant to the Bay of Bengal Programme for the Consultation on Stock Assessment for Small-Scale Fisheries held in Chittagong, June 16-21, 1980. The paper is based on “status papers” submitted to the consultation by member countries, as well as information that emerged during the consultation; additional information from other sources was also utilised. The author and the Bay of Bengal Programme than k the writers of the country status papers and the participants in the consultation for providing most of the material that has gone into the paper. The purpose of this paper is to indicate, to the extent necessary, which of the various stock assessment estimates for the Bay of Bengal region can be reliably adopted by planners for development and management. The paper does not attempt to evaluate or critically examine the existing information.
