利用现有蟹池水体混养青虾和鱼并获高产高效一直是水产养殖和研究者共同探讨的问题。几年来我们采取“塘中塘”培育蟹苗保护水草,合理投放虾、蟹、鱼苗种,种草、投螺蛳等生态养殖法,获得亩产商品虾(规格在5cm以上)50kg、商品河蟹75kg、鱼30kg,比单一养殖亩产增收600元以上。现在 It has been a common problem of aquaculture and researchers to utilize the existing crab pool water for polyculture of freshwater shrimp and fish and to achieve high yield and high efficiency. Over the past few years we adopt “pond in the pond ” to cultivate crabs protect aquatic plants, reasonable delivery of shrimp, crabs, fry seed, grass, cast snails and other ecological farming method, access to mu produce shrimp (specifications in 5cm above) 50kg, Crab 75kg, fish 30kg, more than 600 yuan more than a single breeding mu yield. just now
