水库网箱养殖鳜鱼的研究

Study on Growth and Development of Mandarin Fish (Siniperca chuatsi)Bred by Net box within Reservoir

对鳜鱼在水库网箱养殖中的生长发育进行试验 ,分析养殖经济效益。结果表明 ,将当年早繁鳜鱼种 (大规格 )于 6月底前进箱 ,年底 90 %可以达到商品鳜 ;养殖中 ,饵料鱼的规格不应超过鳜鱼体长的 50 %～55%,饵料鱼不足或过大都会影响鳜鱼采食 ,降低成活率 ;网箱养殖鳜鱼操作方便 ,投入少见效快 ,是一种适宜水库。

An experiment on growth and development of mandarin fish (Siniperca chuatsi) bred by net box within reservoir was carried out.The results showed that the fry (11～13 cm) should be selected and bred before the end of June,the bady length of bait fish should be 50%～55% less than that of mandarin fish,and 90% of the mandarim fish could become commodity one.Economic analysis also showed that this method was simple and efficient,especially in reservoir,lake and other bigger surfaces.
