江苏省盐城市郊区水产养殖场,自1988年以来不断进行技术革新,年年创高产。全场共有养殖水面678亩,其中鱼种池183亩,鱼种池单产都在400kg以上,平均净产300kg以上,鱼种平均规格120g以上。他们的主要技术措施有: 一、有计划、有重点地改造了部分鱼种池,把面积小、水位浅、堤埂塌漏的老池塘改造成稳产高产的精养塘。二、从早字入手,实行科学放养。强化早期培育延长生长期,是搞好鱼种培育的首要环节。该场从4月下旬开始清塘,肥水,培育乌仔。坚持肥水下塘,稀放鱼
Yancheng City, Jiangsu Province, suburb aquaculture farms, since 1988, continuous technological innovation, high yield every year. The total market area of 678 acres of aquaculture, of which 183 acres of fish ponds, fish ponds yield more than 400kg, the average net yield of 300kg above, the average size of more than 120g species. Their main technical measures are as follows: 1. Some planned and focused rebuilding of part of the fish ponds will transform the old pond with small area, shallow water level and embankment collapse into an intensive pond with stable and high yield. Second, start from the word early, the implementation of scientific stocking. Strengthen the early cultivation to extend the growth period, is to do a good job breeding the primary link. The field from the beginning of April Qingtang, fertilizer, nurturing Uzi. Insist on fertilizer ponds, fish sparsely
