Bivalve culture such as clam production is a promising activity as it is more profitable despite a low production rate. However, clam culture has the disadvantage of mainly relying on capture of seed source from the wild. At the same time, due to disease outbreak in the prawn farming sector as a consequence of water deterioration, there has been an overall reduction in aquaculture production. Clam is recognized as a water cleaning machine(filter feeder), thus water quality will be improved if clam can be incorporated into the shrimp farming system. Therefore integrated clam and shrimp culture would reduce risk through. | Technological and Socio-economic Evaluation of clam and Shrimp Culture in North-Central Coast of Vietnam Nhu Van Can Martin S Kumar South Australian Research and Development Institute PO Box 120 Henley Beach South Australia 5022 Aquaculture Research Sub Institute for North Central Vietnam Cua Lo town Nghe An Province Vietnam 1 .

However clam culture has the disadvantage of mainly relying on capture of seed source from the wild. At the same time due to disease outbreak in the prawn farming sector as a consequence of water deterioration there has been an overall reduction in aquaculture production. Clam is recognized as a water cleaning machine filter feeder thus water quality will be improved if clam can be incorporated into the shrimp farming system. Therefore integrated clam and shrimp culture would reduce risk through better pond water quality management and has the potential to improve shrimp and clam production. Banks are reluctant to provide capital funds to the clam industry due to inconsistent production and unreliable technology. The shrimp farming sector suffers a similar fate because of it s high risk due to disease outbreak. .
