摘要
用单养和混养法 ,对建鲤 (Cyprinuscarpiovar .jian)后代选育群体和未选育群体 ;建鲤和黄河鲤 (C .carpio)、建鲤和荷包红鲤 (C .carpiovar .wuyuanensis)的杂交种 ;亲本黄河鲤和荷包红鲤自繁后代 6个试验组进行生长对比。结果表明 ,建鲤选育效果明显 ,品质提高 ;建鲤与黄河鲤杂交具有杂种优势 ,生长快且生长性能进一步提高。
Monoculture and polyculture were employed to conduct the comparison study of growth in 6 groups of fishes which were the larvae of random selected Jian carp (Cyprinus carpio var.jian), selected Jian carp, Jian carp ♀×Huanghe carp(C.carpio) ♂, Jian carp ♀×Hebao red carp(C.carpio var. wuyuanensis)♂, and the self bred progeny of Hebao red carp and Huanghe carp. In the monoculture test the single species was cultured in 1 pond and in the polyculture test the fishes were cultured mixed with other Chinese carp species, respectively. Three replicates were designed for each treatment. The results indicated that the effect of selective breeding is obvious on improving the growth performance and quality of Jian carp in body shape, body color, body size and growth speed, et al. The hybrid of Jian carp×Huanghe carp has the heterosis for its faster growth and improved growth performance.
