在家鱼人工繁殖生产中,提高亲鱼催产率、降低产后亲鱼死亡率,是关系到人繁工作成败的关键性问题。我们在多年的实践中发现,尽管亲鱼的成熟度很好,催产适时,催产剂用量恰当,生态等条件也很适宜,却往往因为雌亲鱼生殖孔红肿结块、堵塞,而造成难产,甚至死亡,影响催产工作的顺利进行,尤其花白鲢亲鱼此现象更为突出。兹介绍本切除术,供参考。
Artificial reproduction in the production of fish in the family, raising the rate of broodstock oxytocin and reduce the mortality of broodstock postpartum, is related to the success or failure of the key issues of human work. In many years of practice, we found that despite the maturity of the broodstock is good, appropriate timing of oxytocin, the amount of oxytocin appropriate, ecological and other conditions are very suitable, but often because of feminine reproductive pores swelling clumps, blockage, causing dystocia and even death , Affecting the smooth progress of oxytocin work, in particular, the phenomenon of gray silver carp broodstock more prominent. Here introduce the resection, for reference.
