摘要
用１０００ｍ３水体的室内育苗池和６口海水土池塘（计１９ｈｍ２）培育中华绒螯蟹（Ｅｒｉｏｃｈｅｉｒｓｉｎｅｎｓｉｓ）苗，比较两种河蟹人工繁殖技术的生态效益和经济效益。经３５天培育表明，土池培育１ｋｇ大眼幼体可获利２０６３元，比室内育苗获利（３９３元）高４２倍；产出投入比（２０７）比室内育苗（１３３）高４５７７％。若采用土池育河蟹苗，每年至少可以少排放各种化学药物４２０ｔ。
Evaluation of profits from artifical reproduction of Chinese mitten crab (Eriocheir
sinensis)was carried out both in earthern seawater ponds and in indoor tanks in 1998.There
were an average yield of 1875kg/hm2(maximum 42kg/hm2)and profits of 2063 yuan RMB/kg
megalopa in earthern Ponds,as much as 42 times higher than that in indoor tanks.The waste
seawater with various chemicals used in the artifical reproduction of Chinese mitten crab in
indoor tanks was reduced by 4200000 tons.The output-input ratio was 4577% higher in earthern
seawater ponds than in an indoor tank.
