银鲫在天然水域产卵时,往往因水温低且变幅大等原因,产卵率和孵化率低,如有目的地控制亲鱼的性腺发育,提高催产和孵化的水温,催产时采用高剂量同时注射多种催情药物,并在人工繁殖中掌握好每个技术环节,可以使其产卵率、受精率、孵化率大幅度提高
Silver crucian carp in natural waters spawning, often due to low water temperature and large amplitude and other reasons, the rate of spawning and hatching is low, such as the purpose of controlling the parent fish gonadal development, increase the rate of oxytocin and hatching, oxytocin high dose Simultaneous injection of a variety of aphrodisiac drugs, and in the artificial reproduction of each technology link, you can make its oviposition rate, fertilization rate, a substantial increase in hatchability
