摘要
对鲤鱼 (Cyprinuscarpio)性腺指数 [GI ,(性腺重 /体重 )× 10 2 ]和斯坦尼氏小体 (corpuscleofStannius ,CS)指数 [CSI ,(CS重 /体重 )× 10 6],以及CS超微结构的变化做了一个年周期的跟踪观察。CSI与GI呈正相关 ;按囊泡和分泌细胞超微结构的变化 ,CS的生长期、分泌期和萎缩期在年周期中逐步演替。这种演替与光镜观察结果一致 ,提示与鲤鱼的繁殖周期密切相关。
The gonad index[GI,(gonad weight/body weight)×10 2],the corpuscle of Stannius (CS) index[CSI,(CS weight/ body weight)×10 6],and the ultrastructure of CS were observed in a reproductive cycle of carps Cyprinus carpio .CSI was positively correlated with the GI;according to the ultrastructure of follicles and secretory cells,the growth phase,secretory phase and atrophy phase of CS were in succession in an annual cycle.Such a change is in accordance with those observed with light microscope,and likely related to the reproductive cycle of carps.
