通过引进抗病草鱼,在同一水域采用统一的管理方式,与普通草鱼进行网箱养殖对比试验,研究总结出两个草鱼品种的养殖试验效果。结果表明,抗病草鱼的抗病能力、生长性能明显优于普通草鱼,其投入产出比1∶1.34,养殖过程不需注射疫苗防病,节本增效显著,养殖效益明显高于普通草鱼;同时,在养殖水环境良好的情况下,采用大规格网箱,适当增加养殖密度可提高面积产量和养殖效益。 Through the introduction of disease-resistant grass carp, a unified management approach was adopted in the same watershed to compare with ordinary grass carp for cage culture, and the breeding test results of two grass carp varieties were summarized. The results showed that disease resistance and growth performance of disease-resistant grass carp was obviously superior to that of common grass carp. The input-output ratio was 1: 1.34, the vaccine was not needed during the breeding process, ; The same time, aquaculture water environment in good circumstances, the use of large-size cage, the appropriate increase in breeding density can increase the area of ​​?? yield and breeding benefits.
