蟹池中通过套养鳜鱼可以大大减少蟹池中野杂鱼的数量,减轻野杂鱼与河蟹争食,降低河蟹饵料系数;同时还可以把池中低质低价的野杂鱼转化成优质高价的鳜鱼。生产实践证明,蟹池中套养鳜鱼不影响河蟹的回捕率,且每667平方米(1亩)能增产5￣15公斤鳜鱼,增收200￣500元。现将这一技术介 Crab pool by raising catfish can greatly reduce the number of wild crabs in the trash, reduce trash and crab fight food, reduce crab feed coefficient; at the same time can also be low-quality low-cost pool of trash into high-quality High-priced bonito. Production practice has proved that the raising of cichlid catfish ponds does not affect the recovery rate of crabs, and every 667 square meters (1 acre) to increase production of 5 to 15 kg catfish, an increase of 200 to 500 yuan. Now this technical introduction
