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 *** 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 ***, the disorder development and excessive exploitation of aquaculture poses negative environmental influences, particularly the fish and shrimp culture which require large exotic energy *** huge terrestrial nutrient input together with the discharging nitrogen (N) and phosphorus (P) from intensive mariculture lead to eutrophication aggravation in major Chinese coastal *** the eutrophical symptoms can cause a succession of serious loss of ecological, economic and social benefits of coastal waters.
