研究了人工饲养的雌雄同体硬骨鱼金鲷在生命的头两年内的性腺周期。直到8个月大时，双性性腺的背侧卵巢部分仍占主导地位。在生命第一年结束时的第一个繁殖季节，性腺的腹侧睾丸部分增殖，形成成熟的睾丸。在第一个繁殖季节结束时，所有的鱼都开始进行性别逆转。从 17 个月大开始，发育朝两个方向进行：大约 80 个月。人口中的100人完成了性别逆转过程，个体发育为雌性；在其余人口中，性别逆转过程尚未完成，个体发育为男性。
The gonadal cycle of the hermaphroditic teleost Sparus aurata reared in captivity was studied during the first two years of life. Until the age of 8 months, the dorsal ovarian part of the bisexual gonad was dominant. Towards the first breeding season at the end of the first year of life, the ventral testicular part of the gonad proliferated, forming a mature testis. At the end of the first breeding season, all the fish began to undergo sex reversal. From the age of 17 months, development proceeded in two directions : in about 80 p. 100 of the population the sex reversal process was completed and the individuals developed into females ; in the rest of the population the sex reversal process was not completed and the individuals developed into males.
