岩原鲤池塘育种技术研究

Research of Pond Breeding Technology of Procypris rabaudi

为给岩原鲤的商品鱼进行规模化成鱼养殖提供充足的优质鱼种,结合生产实践研究岩原鲤的池塘育种方法。采用不同的养殖密度(120万、150万尾/hm2)和不同的饲料配方(饲料蛋白含量分别为34.3%和38.5%)养殖相同规格的岩原鲤鱼种。结果表明:选择3 cm的岩原鲤鱼种,投喂蛋白含量38.5%的饵料经过10个月的养殖全长可达13.5 cm,平均成活率达到91.25%,经济效益较好。

In order to provide high quality fish for large scale fish breeding of marketable Procypris rabaudi,combining with production practice, the pond breeding technologies of Procypris rabaudi were researched, using different breeding density （1.2 and 1.5 million/hm^2）and different feed formula（protein contents of feed were 34.3% and 38.5% respectively）breed the Procypris rabaudi fingerling that with same specifications.The results showed that：choose Procypris rabaudi fingerling with 3 centimeters length ,feeding with feed that 38.5% protein content for 10 months, then the length of the fish reached 13.5 centimeters, the average survival rate reached 91.25%, realized good economic benefit.
