我们通过总结鳜鱼繁养的经验教训和学习外地经验,结合本地的实际认为要提高鳜鱼“火片”(夏花鱼种或寸片)的成活率,必须抓好以下技术措施: 1、鳜鱼苗孵化后能否及时吃到第一尾鱼苗是提高成活率的关键。一般催产鳜鱼,也要同时催产团头鲂或草鱼等饵料鱼,最理想的是团头鲂。因为团头鲂鱼苗细长柔软、游泳能力差,鳜鱼容易捕捉,也是适口性强的活饵料。随着鳜鱼苗的生长,供应饵料鱼也要随之增加。在供应饵料鱼时,一般应控制饵料鱼在
We summed up the lessons learned from the bream fish and learn from foreign experience, combined with the local reality that to improve the survival rate of the catfish “fire piece” (summer flower species or inch pieces), we must grasp the following technical measures: Catfish hatching after hatching can eat the first fish fry is to improve the survival rate of the key. General barbary nourishment, but also the same time otorrhagia or grass carp bait fish, the best is the head 鲂. Because the bream fish fry slender and soft, poor swimming ability, catfish easy to catch, but also a palatable live bait. With the growth of bream fry, the supply of bait fish will also increase. In the supply of bait fish, bait fish should generally be controlled
