Abstract
The objectives of the present study were to determine the relationships between sperm characteristics (density and pH) and fertilization capacity (hatching rate) for Persian sturgeon during their reproductive season. Eleven males were used in this study. The luteinizing hormone releasing hormone analog was used to induce spermiation following which semen samples were stripped. Statistical analysis revealed positive correlations between hatching rate and sperm pH (P 0.01, r = −0.745). We suggest that understanding these correlations is critical in the evaluation of sperm quality and for the composition of media (extender) to be used in the dilution of semen to improve sperm motility/fertility parameters of Persian sturgeon.
