    Biosocioeconomic Assessment of the Effects of Fish Aggregating Devices in the Tuna Fishery in the Maldives - BOBP/WP/95 1994

    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).

    Studies of the Tuna Resource in the EEZs of Sri Lanka and Maldives - BOBP/REP/41 1987

    Tuna are an important fishery resource in the exclusive economic zones of Maldives and Sri Lanka. In June 1984, a working group comprising representatives from the two countries met in Sri Lanka to take stock of available knowledge on tuna, identify gaps in that knowledge and evolve a workplan to fill the gaps. These were summarized in BOBP/WP/31. The present report covers later investigations and updates knowledge on the tuna resources in the EEZs of Maldives and Sri Lanka. During this wor k, the working group met in Male, Maldives (October 1985) and in Colombo, Sri Lanka (September 1986). These meetings discussed the sampling programmes conducted by Maldives and Sri Lanka. This report, as well as the meetings of the tuna working group and the sampling programme were sponsored by the “Marine Fishery Resources Management” component (RAS/81/051) of the Bay of Bengal Programme (BOBP). The project commenced January 1983 and terminated in December 1986. It was funded by the UNDP ( United Nations Development Programme). Its immediate objective was to improve the practice of fishery resources assessment among participating countries (Bangladesh, Sri Lanka, Maldives, Malaysia, Thailand, Indonesia) and to stimulate and assist in joint management activities among countries sharing fish stocks.

    The product was given to staff and visitors of the MMDC, comprising Palauans, Americans and Japanese, to taste. The end product had a matt, dark amber to woody colour, the texture being chewy but not unpleasantly so. The taste being only slightly salty, with a light sweetness and a clear clam taste. The smoked mantle took up the shape of a ring. This product being considered more tasty, if more chewy than the adductor muscle. The coloured part of the processed mantle ended up a ve ry dark green, almost black, with a certain vegetable taste to it. Some tasters in the panel objected to this part of the meat, but it was considered important to leave it in order to give the product a typical “giant clam” appearance, and to avoid further weight loss. The surface of the cut appeared translucent white. The adductor muscle, although more appealing in aspect, had a blander taste and a more outspoken “grain” in the structure. The colour of the cut is of a more opaque whit e. After trials, the panel found the smoked guts to be a less valuable product, although the taste is good. These were therefore not utilised in later experiments. 3 1801g 612g 420g 563g 389g 171g 549g 386g 165g 411g 302g 127g 31% 63.5% 40.7% 97% 99% 96.5% 75% 78.2% 77% 29.5% 5 6920g 2240g 3090g 1683g 1192g - 1536g 1094g - 1324g 981g 24.3% 53.2% - 91% 92% - 86.2% 89.7% - 25.2% 7 2865g 902g 1415g 752g 473g - 679g 441g - 531g 364g - 26.2% 52.4% - 90.3 92.2% - 78.2% 82.2% 23.8% Legend: Exp. = experiment number;M = mantle;A = adductor
