China s mariculmral scale has been growing steadily with the transformation of traditional fishing since the 80 s, due to the decline of fishery resource and capture in coastal areas.During 2008, the annual production of shellfish, fish, crustaceans and seaweed were 10.08,0.75, 0.94 and 1.39 million tones, respectively, with a total yield of 13.40 million tones (CHINA OCEAN YEARBOOK, 2009).Such rapid development of mariculture provides for abundant proteins and contributes enormous benefit to alleviate China s food pressure caused by population increase.However, the disorder development and excessive exploitation of aquaculture poses negative environmental influences, particularly the fish and shrimp culture which require large exotic energy input.The huge terrestrial nutrient input together with the discharging nitrogen (N) and phosphorus (P) from intensive mariculture lead to eutrophication aggravation in major Chinese coastal systems.And the eutrophical symptoms can cause a succession of serious loss of ecological, economic and social benefits of coastal waters.
