Abstract

Blood serum testosterone (T), progesterone (P4), estradiol (E2) and CORTISOL concentrations were measured by radio-immunoassay (RIA) in FARMED STELLATE STURGEON (Acipenser stellatus) female breeders during final maturation (FM) induced by GNRH (Ova-Fact III). After the detection of polar indices (PI=10-14) and hormonal survey in female breeders was carried out to induce by GNRH in 2 stage with 10mg/kg dose with interval 12 hour. Three blood samples were taken from females in timing 0, 12, 24 h after injection. Results showed there was a significant of sex steroid T, P4, E2 and CORTISOL levels in non-ovulated (n=2) with ovulated (n=5) fish. T, P4, E2 levels were decreased after ovulastion while CORTISOL increased. The data indicates that SEX STEROIDS, especially T, in farmef femal stellate sturgeon brood stock had important role in OVULATION also T concenteration in non-ovulated females were significantly lower than in ovulated fish (P<0.05). The rise in CORTISOL level may indicate an interaction between corticosteroids and gamete maturation in FARMED STELLATE STURGEON.
