Effect of cortisol on testis of freshwater fish Notopterus notopterus (Pallas).

چکیده
Cortisol (20, 40 and 60 micrograms/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.

Effect of cortisol on female freshwater fish Notopterus notopterus.
In the present study, effect of cortisol on the ovary of the freshwater fish Notopterus notopterus was studied during four phases of the reproductive cycle. The hormone was injected 60microg/fish for ten days. Cortisol in fish is known to increase the metabolic activity. After the hormone treatment the ovarian somatic index and the hepatosomatic index increases during non breeding phase. The yo...

The pituitary gland of Notopterus notopterus (Pallas, 1769) was situated in a shallow pit at the floor of the skull and attached to the infundibulum. On the basis of tinctorial properties the cell types of pituitary were indentified which were distributed in the rostral pars distalis (RPD) proximal pars distalis (PPD) and pars intermedia (PI) in different proportions. The three zones were inner...
