Abstract: (8578 Views)
This study was carried out during the artificial propagation season in the shahid beheshti Sturgeon Rearing and Propagation Center and International STURGEON Research Institute (Rasht) during 2009. Eleven wild male Acipenser Persicus brood fish were used for this study. Each brood fish was stripped after receiving hormone injection and then sperm samples were examined separately. Fertilization rate and hatching rate of larvae were also determined. Analysis of relationship between sperm pHand density and indices of reproduction showed positive and direct relationship between hatching rate and sperm pH (p<0.05, r=0.711), as well as between sperm pH and fertilization rate (p<0.05, r=0.633). However egative relationship was opserved between sperm density and fertilization rate(p<0.05, r=0.640) and between sperm density and hatching rate (p<0.05, r=0.745).
