The present application relates to the technical field of
aquaculture, and particularly relates to an artificial breeding method of Cottus hangi in Xingkai Lake. The present application uses LRH-A2 and HCG combination
oxytocin to reasonably inject female parent fish and male parent fish, especially to twice injection of female parent fish, and strictly controls injection
dose of each injection and reasonable control time interval, which not only can efficiently induce labor, but also can reach 95% of the female parent fish induction efficiency, and can obtain good ovum and
semen, so that the ovum can be better fertilized, the quality of the fertilized ovum is improved, the
hatching rate is improved, the stress of the parent fish is reduced, and the death of the parent fish is reduced. The present application improves the
physical fitness of the parent fish through reasonable parent fish cultivation, and combines reasonable artificial induction operation and post-production
nursing measures, so that the post-production death of the parent fish is reduced from multiple aspects, and the post-production
survival rate of the parent fish is significantly improved, so that the repeated cultivation cost of the parent fish is reduced.
