随着网箱养鱼发展规模的扩大,饲料来源问题日益突出,特别是高温季节尤甚,成为网箱养鱼发展的一大制约因素。为此,县水产技术部门采取了“以青为主,青精结合”多途径的办法解决了网箱养草鱼的饲料来源,保证了网箱养草鱼的持续、稳定、协调地发展。一、“以青为主,青精结合”解决草鱼的饲料来源 1.以青饲料为主体 (1)充分利用优质野旱草养鱼柘溪水库库区共有果园4万亩,消落区5万多亩,这些果园和消落区常年杂草丛生,其中绝大部分的野杂草是草鱼的好饲料,营养价值也比较高。在3—4月份以刈割野杂草养鱼为主,5—9月份充分利用野杂草。1992年共刈割野草614.8t,

To this end, the county aquaculture technology department has adopted a multi-channel approach of “focusing on the youth and integrating the youth and the environment” to solve the feed sources of the cage grass carp and ensure the continuous, stable and coordinated development of the cage grass carp. First, the “green-based, green combination of” to solve the grass carp feed sources 1.
