一、调整品种结构,主养或套养优质鱼。目前,草、蝙、鲫、青等鱼仍具有市场优势,其价格比鲤、鲢、鳙每公斤约分别高出2～3元,养殖者应着重增加这些品种的放养量,把优质鱼与常规鱼的比例调整为80:20,还应套养鳜鱼、大口鲶、淡水白鲳、黄颡鱼、青虾、乌鳢等名特优品种。此举既可除野,又不增加投饵施肥,每亩水面可增收200～500元。二、实行综合养殖。可因地制宜采取以下几种模式:1.鸡-猪-鱼综合养殖:用精料喂鸡,鸡粪发酵后拌料喂猪。据试验,用100只鸡的粪喂猪,可生产猪肉120公斤,用猪粪喂鱼可产鱼50公斤。2.鱼-猪综合养殖:每亩水面配养猪4～5头,猪粪可产肥水鱼200～250公斤,
First, adjust the variety of structure, the main raise or raise quality fish. At present, the grass, bat, crucian carp, green and other fish still have market advantages, the price of carp, silver carp and bighead carp, respectively, about 2 to 3 yuan per kilogram, farmers should focus on increasing the stocking of these varieties, The proportion of conventional fish adjusted to 80:20, should also be raised catfish, catfish, freshwater white catfish, catfish, freshwater shrimp, catfish and other famous premium varieties. This move can remove the field, without increasing the fertilization of fertilizers, water per acre can increase 200 ~ 500 yuan. Second, the implementation of integrated farming. Can be adapted to local conditions to take the following modes: 1 chicken - pig - fish integrated culture: with fine feed chicken, chicken manure fermented feed pigs. According to the test, pigs with 100 chickens can produce 120 kilos of pork and 50 kilograms of chickens can be fed with pig manure. 2. Fish - Integrated pig farming: 4 to 5 pigs per acre of water surface, pig manure can produce 200 to 250 kilograms of water fish,
