Abstract

PERSIAN STURGEON (Acipenser Persicus Borodin 1897) is an important species in economy of fisheries in the south coast of Caspian sea there by attention to its biology is necessary. For study on the changes of SEX STEROIDS Testosterone (T), 17 -b - Estradiol (E2) Progesterone (P) and its relation with stage of OOCYTE maturity in PERSIAN STURGEON, 86 specimens were sampled and investigated in 1999 and 2000. Results showed that before vitellogenesis T, E2 and P levels were relatively low (0.25, 0.55 and 0.32 ng/ml respectively). But during the vitellogenesis (III thstage of OOCYTE maturity)the levels of T, E2 and P increased considerably and reached up to 8.55, 4.53 and 0.52 ng/ml respectively and it was significantly different comparing to previous stage (p<0.05). In IVth stage, when nucleus had migrated toward animal pole, level of SEX STEROIDS decreased (T=7.44, E2 =2.65 and P=0.36 ng/ml) and in the case of E2 and P level it was Significant (p<0.05). GSI in 11th, IIIth and IVstage of gonad maturity were 2.44%, 13.11% and 21.18% respectively (p<0.05).
