鲤鱼起捕率低是多年来淡养的一个很难解决的问题。我所为了搞清抗寒和高起捕率的遗传规律,先后进行了柏氏鲤与黑龙江鲤、德国镜鲤、荷包红鲤等的正反杂交。从中选出一组双杂交种 [(柏氏鲤×镜鲤 )F1× (黑龙江鲤×红镜鲤 )F1],此组种系具有较强的抗寒能力,起捕率却不很高
The low rate of carp fishing is a difficult problem to solve for many years. In order to find out the genetic law of cold-resistant and high-catch rate, we carried out the positive and negative hybridization of Burkina carp and Heilongjiang carp, German mirror carp and purse red carp. A group of two-hybrid [F1] (Heilongjiang carp × red mirror carp) F1 was selected from the group of two-hybrid [F1]. The germline of this group has strong cold resistance and the rate of capture is not very high
