| Abstract: | Cortisol (20, 40 and 60μg / fish for 10 days) treatment caused an increase in testicular- somatic index (TSI) in immature N. notopterus whereas in mature fish no change from that of controls was observed. Histology of testis indicated that spermatogenetic activity was activated in immature fish while it was inhibited in mature fish. Testicular cholesterol exhibited a similar response. The results indicate that cortisol inhibits spermatogenesis during mature phase while it promotes spermatogenesis during immature phase of the reproductive cycle in N. notopterus. |
