本文以北方几种养殖鲤鱼为对象，根据鱼类性腺发育生理学，通过对不同时间、催产药物剂量的调整和生态条件（产卵池水体、水位变化及产卵池水温）的调节，了解对鲤亲鱼催产率的影响。实验证明以上几种方法，都能不同程度的提高鲤鱼亲鱼的催产率。为今后的渔业生产提供更科学的依据。
Based on the gonadal developmental physiology of fish, we adjusted the dose of oxytocin and ecological conditions (the water body and water level in the spawning pool and the water temperature in the spawning pool) Effect of brood stocking rate. Experiments show that the above methods can improve the carp broodstock oxytocin rate to varying degrees. Provide a more scientific basis for the future fishery production.
