近年来，水产养殖业发展迅猛，水产品由“卖方市场”转向“买方市场”，价格不断下跌，造成养殖效益下降，甚至亏损。为了探索新的水产养殖模式，我们于2000年根据水产生物学、生态学原理，在池塘中进行鱼、虾、蟹、鳝、鳅等多品种混养试验，采取模拟自然生态环境条件，发挥了 In recent years, with the rapid development of aquaculture, aquatic products have been diverted from the “seller’s market” to the “buyer’s market” and prices have been declining, resulting in a decrease in the profitability of aquaculture or even a loss. In order to explore the new aquaculture model, we conducted polyculture experiments of fish, shrimp, crabs, eel and loach in ponds in accordance with the principles of aquatic biology and ecology in 2000. We simulated the natural ecological environment and played a
