虹鳟发眼卵孵化及苗种培育技术总结

Summary of rainbow trout(Oncorhynchus mykiss) eyed egg hatching and seed breeding techniques

孵化虹鳟发眼卵3万粒,经9 d孵化培育,完成孵化出苗,经过90 d培育,养殖规格达到10~11 cm,成活率84%。选择微流水孵化及苗种培育,能够有效提高虹鳟苗种的成活率。

A total of 30,000 rainbow trout(Oncorhynchus mykiss)eyed eggs were incubated, and after 9 days of hatching and breeding, hatched fry. After 90 days of cultivation, the breeding specification of rainbow trout reached 10 to 11cm, and the survival rate was 84%. The micro-flow water hatching and seed breeding chosen can effectively improve the survival rate of rainbow trout seedlings.
