No results found.Against the background of the small scale fisheries of the Indo-Pacific region, the paper reviews the need for and relevance of an intermediate technology approach to fisheries development. This is in view of the impending energy crisis, the increasing socio-economic problems of rural fishermen, and the unemployment, pollution, waste and resource depletion resulting from some industrial fishery activities. To avoid future dependance on diminishing resources of fossil fuels, available substitute fuels from organic sources are recommended. Natural energy sources which can power vessels, fish plants, vehicles and fish farms are discussed. Technologies which are low in capital cost and energy requirements and are appropriate to rural fishing villages, are outlined. In view of the current critical situation and the emergence of an appropriate intermediate technology, the writer examines ways in which small scale fisheries may benefit by adapting vessels, fishing methods, fish processing and fish farming activities to obtain the maximum production at the minimum energy consumption and minimum waste of raw materials, while conserving the resource and providing useful, interesting and remunerative work for fishermen and their families. Integrated village systems are proposed and the writer concludes by outlining the potential benefits of wise application of the principles to small scale fisheries throughout the world. -

Institutional Strengthening in the Fisheries Sector, Bangladesh
1992Also available in:
No results found.To meet the present demand of large size (about 10 cm) carp fingerling for massive open water stocking in Bangladesh, a modified technology of large size carp fingerling production was demonstrated at four government farms, utilizing locally available facilities and feed ingredients. In the modified system production was 10602292 kg/ha in 3050 days. This rate of production in one cycle is about 4 times higher than the production under the traditional system of large size fingerling rearing. With increased management skills, raising of 45 crops of large size fingerling was found technically feasible. This means that the improved system has the potential for producing 53005500 kg of large fingerling/ha/season. By further improvement of feeding system production can be increased up to 900010500 kg/ha/season by year round multicycle multispecies culture. Against the traditional stocking rates of 40140 prenursed fry/m2, the modified system used only 819 fry/m2, but produced a much hig her biomass of larger fingerling of substantially higher sale value. Production cost of 1 kg fingerling was Tk. 42. Profit over investment was Tk. 25 (60%) in modified system, which is significantly higher than the traditional (Tk. 19/kg i.e. 18%) technology. But the production cost of fingerlings in modified system will be Tk.27/kg when the farmers will use their own stocking material instead of buying. In that case the profit will be 148%. -
