摘要
从美国引进虹鳟鱼三倍体发眼卵。对鱼卵的人工孵化、苗种培育以及疾病预防等环节进行试验。试验结果表明:虹鳟鱼三倍体的人工繁育易于管理,苗种生长速度快、抗病能力强、市场价值高。养殖户们利用原有的虹鳟鱼池即可进行养殖,市场发展前景良好。大力推广三倍体养殖对调整冷水鱼产业结构,实现渔业增效、渔农增收具有极大的推动作用。
The triploid rainbow trout which introduced from the United States was used for the artificial breeding.It carried out the experiments about the artificial incubation of eggs,seedling cultivation,disease prevention and the other aspects.The results showed that the artificial breeding of triploid rainbow trout was manageable.The seedling growth speed was fast and it had a strong disease resistance.The triploid rainbow trout had a high market value.Farmers could use the original pond for the breeding which had a good market prospect.Therefore vigorously promote of the triploid breeding had a great promoting role for adjusting cold water fish industry structure,the implementation of the fishing efficiency and increase income.
