摘要
为研究中草药复合添加剂“富康163”对水库网箱养殖靬金鳟和虹鳟生长效果的影响,分别设置了两个试验箱和对照箱。试验箱添加2%“富康163”,在水温13℃～20℃条件下,经42d的养殖试验,结果表明,相同含量的“富康163”对不同饲养密度的网箱养殖靬金鳟和虹鳟的增重倍数、日平均增长率、饲料系数和成活率均产生不同程度的影响,其中以放养密度高的虹鳟试验箱增产效果尤为显著。
Herbal medicine of ＂Fukang 163＂was applied in trout net box culture in order to assess the influence of growth of golden and rainbow trout, the experiment was divided into two test and tow control groups. Under the conditions of 13℃～20℃, two test groups were added the same content of 2% ＂Fukang 163＂ and reared 42 days. As a result, the data showed that ＂Fukang 163＂ make a difference to some extend in trout culture with different farming density, mainly embodied in net weight, daily average growth rate, food efficiency and survival rate, especially, a significant difference is produced for rainbow trout with high farming density.
