Abstract
Clam aquaculture has been practiced in Nam Thinh commune, Tien Hai district since 1989, but exhibited instabilllity recently, especially in terms of economic aspect. The study aimed to analyze the economic performance of clam aquaculture and propose recommendations to develop clam aquaculture in a more sustainable manner. A household survey of 48 clam farmers and key informant interviews were conducted in 2012. Gross margin analysis and comparative statistics with t-test and F - test were employed to analyze data. Results show that given the existing resources, technical level, and farmers’ expertise, farms specializing in meat clam aquaculture, and/or operating at medium size, have highest economic performance. A number of problems relating to resources, seed, techniques, knowledge, water conditions, and social conflicts were addressed and recommendations to develop clam aquaculture were proposed accordingly.
