吉林省具有丰富的大水面资源,由于池塘培育鱼种成本高,致使大水面鱼种放养不足,大水面的鱼产潜力得不到发挥,严重地影响了吉林省鱼产量。利用网围育种,是一项投资小、见效快、效益高的有效育种途径。一、养殖效果好网围养鱼生态条件优越,放养密度大,鱼苗成活率高,生长速度快,饵料利用率高、优质鱼多,规格整齐。二、经济效益好网围养殖不占用农田,不需要征用土地,节约了开挖鱼池和养鱼 Jilin Province is rich in surface water resources. Due to the high cost of fostering species in ponds, large-surface-surface fish species are stocked inadequately and the potential for large-scale surface-water fish production can not be fully realized, which has seriously affected the fish production in Jilin Province. The use of net breeding, is a small investment, quick, effective and effective breeding methods. First, the aquaculture effect is good Wai Wai fish superior ecological conditions, stocking density, high survival rate of fry, fast growth, high utilization of food, high-quality fish, neat specifications. Second, good economic returns Wai Wai farming do not take up farmland, do not need to requisition land, saving fish ponds and fish culture
