Effect of follicle stimulating hormone on female Catla catla (Ham.).
The exogenously administered FSH in Catla catla clearly reveals that a dose of 0.2 mg and 0.4 mg of FSH does not have any marked effect on the ovary, but the vitellogenesis begins with a further dose of 0.2 mg of the same. A rapid accumulation of yolk is recorded in the primary oocytes with a total dose of 0.8 mg of FSH, however, this much hormone is not enough for the spawning. The latter has been recorded with 1.0 mg of FSH which swifts with a dose of 1.2 mg of FSH. The number of mature follicle declines with 1.4 mg of FSH whereas no empty follicle is seen with the same treatment. With each addition of 0.2 mg of FSH upto 2.0 mg the number of oogonia and primary oocytes increases while maturing and mature follicles show a downward tendency.
