Summary

‘In vivo’ effects of estradiol-17β were investigated in females of the teleostBarbus conchonius during the non-breeding phase. Fish treated with 25 μg estradiol-17β/individual revealed significant hypoglycemia and a reduction in liver glycogen reserves. Plasma amino nitrogen, FFA, and organic PO4 were elevated after estradiol therapy, whereas plasma cholesterol decreased. Liver cholesterol also fell in the treated fish. Estradiol-17β seems to play a crucial role in the initial stages of ovarian recrudescence by mobilizing energy reserves.
