摘要
本研究旨在通过血清的SDS－PAGE分析和生殖腺组织学切片观察，探讨加州鲈鱼性腺发育状况。结果表明：12月份雌鱼卵巢以Ⅲ时相卵母细胞为主，少数发育程度较好的雌鱼血清中出现雌性特异性蛋白带（FSPP）；3月份卵巢以Ⅳ时相早、中期如母细胞为主，雌鱼血清均有FSPP；而4月份的雌鱼卵巢以Ⅳ时相卵母细胞为主，并有少量排空的滤泡囊。因此可知加州鲈鱼到3月份性腺趋于成熟，4月份雌鱼已至少产过一次卵，而同期血清中存在FSPP则可能是该鱼分批再次排卵的物质基础。
The Development of Micropterus salmonoides' glandula genitalis was studied through micro-observation of histological sections and SDS-PAGE of serum at the same phase. In December, the majorities of oocytes of female fish are at Ⅲ phase, and there is FSPP in serum of some better developed females. In March, the oocytes are mainly at early and middle Ⅳ phase, and all females' serum contains FSPP.In April, most oocytes are at the end of Ⅳ phase and some follicle vesica also exist in the ovary . These indicate that the glandula genitalis get maturing in March, and in April the female fish have laid eggs at least one time.
