Abstract

In order to determine the relationship between SEX STEROIDS and the quality of artificial propagation of Persian sturgeon, blood samples were obtained from ripped females, with proper germinal vesicle position (G.v.), before pituitary gland suspension injection. The level of the SEX STEROIDS including: Testosterone (T); 17 b- estradiol (E2) and progesterone (P) were determined and propagation qualities including: fertilization rate survival rate of incubation and larval stages, were recorded during development of eggs and larval stages. Females based on the fertilization rate were divided in two groups and higher than 50% fertilization rate named as first and lower than 50% as second group. The levels of T and E2 were significantly higher in first group than the second group of females (p<0.01). Changes in T and E2 levels were correlated with the fertilization rate but there was no significant difference and correlation between p levels and fertilization rate. Germinal vesicle break down (GVBD) were happened completely in the first group and incompletely in the second group of females (p<.001) Survival rate of incubation stage and first larval stage (yolk absorption stage) were significantly higher in the first group than higher than second group respectively (p<0.001, p<0.05) but there were no differences in the second larval stage (exogenous feeding stage p>0.05).
