| 摘 要： | 本文对利用泉水集约化养殖哲罗鲑的生长情况、饵料系数、养殖成活率、病害防治进行了总结,并进行了养殖密度和饲料对比试验.经过323d的养殖,哲罗鲑从初始时的1.59g/尾增长到1020g/尾,达到了上市标准,养殖成活率84.84%,饵料系数0.86;密度和饲料实验表明放养800尾/池的哲罗鲑能够获得较好的效果,且投喂进口饲料的哲罗鲑饵料系数0.92,每Kg鱼饲料成本9.05元,投喂国产饲料的哲罗鲑饵料系数1.05,每Kg鱼饲料成本7.66元;影响哲罗鲑的主要疾病是小瓜虫病、烂鳃病和出血病,要提早预防.

| Abstract: | The growth condition,feed coefficient,survival rate and disease prevention and cure of spring intensive aquaculture in Hucho taimen were summarized,meanwhile,the contrast experiment of culture density scenarios and feed usage were also conducted in this paper.Through 323 days raising,the body weight of Hucho taimen increased from 1.59g to 1020g reaching the market standard.The survival rate is 84.84% and feed coefficient is 0.86,respectively.The cultural experiment showed that the fittest culture density is... |
