Abstract

From September 1980 to August 1981 the serum levels of 11-oxotestosterone (11-O-T) in 231 male and of 17 beta-estradiol (E2) in 207 female rainbow trout were measured radioimmunologically, and compared with the development stages of the gonads. Using histological criteria, testicular development was divided into seven stages, and ovarian development into four stages. In males, 11-O-T levels remained below 6 ng/ml until the appearance of spermatozoa. Maximum values (126 ng/ml) were observed in spermiating males. In females, E2 levels were below 2 ng/ml during the period of slow oocyte growth. Maximum values (average of 31 ng/ml) were observed during exogenous vitellogenesis.

摘要

1980年9月至1981年8月，采用放射免疫法测定了231条雄性虹鳟鱼的11 - 氧睾酮（11 - O - T）血清水平以及207条雌性虹鳟鱼的17β - 雌二醇（E2）血清水平，并与性腺的发育阶段进行了比较。根据组织学标准，将睾丸发育分为七个阶段，卵巢发育分为四个阶段。在雄性中，直到精子出现时，11 - O - T水平一直低于6 ng/ml。在排精期雄性中观察到最大值（126 ng/ml）。在雌性中，卵母细胞缓慢生长期间E2水平低于2 ng/ml。在外源卵黄发生期间观察到最大值（平均31 ng/ml）。
