| 摘 要： | 应用放射免疫测定法,研究了草鱼、鲢鱼催产前后血液中GTH含量的变化。催产后草鱼、鲢鱼血液中GTH的含量增加到“排卵阈值”水平,也就是比产卵前增加30-40倍,产卵活动才能实现。由此阐述了鱼类也象其他脊椎动物一样,存在着丘脑下部——垂体——性腺系统的调节机制。

| Abstract: | The synthetic anaiogue of hypothalamic luteinizng hormone releasing hormone(LRTJ--A) has been used as a stimulant for induced spamning of fishes. Serum gonadotropin(GTH) levels have been measured by means of radioimmunoassay before and behind spa-wning of grass carp (Ctenopharynodon idellus) and silver carp (Hypophthalmichthysmolitrix). The experiments showed that the spawning of the carps would take place onlywhen the serum gonadotropin levels reached to a "threshold valus of ovulation", i. e. about30--40 times higher than that before the inducement. This reveals that the mechanism ofreproductive physiology of fish, is also represented by the hypothalamus-hypophysis-gonad system as well as in other vertebrates. |
