锦鲤鱼的繁殖不是很难,但是要使锦鲤的体色特征稳定保持并稳定地传到下一代就很难。锦鲤的体色特征是由基因控制的,一般情况下是不稳定的。要得到稳定的基因变异,必须进行复杂的杂交与间交,得到稳定的变异基因并通过进一步的繁殖试验才能得到一个稳定品种。而且不排除在繁殖过程中进行另外的变异组合,这是一个长期的工作,不是一年两年就能够完成的。按常理推断,大正三色与大正 Koi fish breeding is not difficult, but it is hard to keep Koi’s body color characteristics stably and stably to the next generation. Koi carp color characteristics are controlled by the gene, under normal circumstances is not stable. To get stable genetic variation, it is necessary to carry out complex hybridization and intercrossing, to obtain a stable variant gene and to pass a further breeding experiment to obtain a stable variety. And it does not exclude the possibility of carrying out another combination of mutation in the breeding process. This is a long-term task that can not be completed within a year or two. According to common sense, Taisho tricolor and Taisho
