摘　　要：寻求生态高效水产养殖新模式对于兴化市发展水产养殖业具有重要意义。本研究探讨了河蟹与小龙虾混养、河蟹与青虾混养和河蟹单养3种不同养殖模式产量、产值及成本利润率的差异。结果表明:河蟹与小龙虾混养模式经济效益最好(68478.0元/hm^(2)),成本利润率最高(83.9%);其次是河蟹与青虾混养模式;河蟹单养模式成本利润率最低。河蟹与小龙虾混养模式符合当前水产养殖转型升级、绿色和高质量发展的需求,可在兴化市垛田街道及周边地区推广。It is of great significance to seek a new eco-efficient aquaculture model for the development of aquaculture in Xinghua City.This study investigated the differences in yield,output value and cost-profit rate of three different aquaculture modes:coculture of crab and crayfish,coculture of crab and freshwater shrimp and single culture of crab.The results showed that the coculture mode of crab and crayfish had the best economic benefit(68478.0 yuan/hm^(2))and the highest cost-profit rate(83.9%).The second was the coculture mode of crab and freshwater shrimp.The cost-profit rate was lowest in the single culture mode of crab.The coculture mode of crab and crayfish meets the demands of transformation and upgrading,green and high-quality development of current aquaculture,and can be promoted in Xinghua City and its surrounding areas.
