白鲫鱼肉味细嫩,养殖方法较普及,繁殖率高、产孵率高、养殖范围广,可在池塘、水库、湖泊、网箱等地养殖。现介绍几种养殖方法: 1.粗放养殖。根据池塘生产力适量投放苗种,不施肥、不投饵,1~3年后起捕商品鱼。一般池塘产量达100~200千克/公顷,许多池塘产量达400~500千克/公顷。 2.施肥养殖。在无有机肥流入、营养元素少、透明度高的贮水池,通过施肥,促使浮游生物繁殖,以其为饵料来养殖白鲫。按每公顷施用95千克硝铵,16千克过磷酸钙,投入118千克白鲫苗种,年产量可达500
White carp tender meat, breeding methods are more popular, high reproductive rate, high rate of hatching, breeding a wide range of ponds, reservoirs, lakes, cages and other breeding. Now introduce several farming methods: 1. Extensive farming. Depending on the amount of pond productivity seed, no fertilizer, no bait, 1 to 3 years after the start of catch fish. Typical ponds yield between 100 and 200 kg / ha and many ponds produce between 400 and 500 kg / ha. Fertilization breeding In the absence of organic fertilizer inflow, less nutrient elements, high transparency of the reservoir, through fertilization, to promote plankton breeding, as its breeding bait to crucian carp. Applying 95 kg of ammonium nitrate and 16 kg of superphosphate per hectare, putting 118 kg of white crucian carp seed, the annual output of up to 500
