Abstract

The normative of two ACIPENSER PERSICUS broodstoks were scored during spawning season in 2002-2003. The breeders were caught from the southern part of the Caspian Sea. 158 breeders of Shahid Rajaii fish farm and 269 of Shahid Marjani were investigated. After checking egg quality and hormonal injection of fish, harvested egg were fertilized by common sturgeon hatchery method. Incubation temperature was about 17-22°C and hatchery period lasted 5-7 days (110-115 degree-days). About 55 percent of breeders had response to hypophysis injection. The range of somatic index (G.V) of spawned fish was varied from 4.4 to 9.9 in Shahid Rajaii farm and 4.73 to 10.96 in Shahid Marjani farm. In immature breeders it was more than 11. The optimum temperature spawning was from 15.5 to 18°C and 17 to 20°Cin Shahid Rajaii and Shahid Marjani farm respectively. The average weights of breeders were 28.14 in Shahid Rajaii farm and in Shahid Marjani farm were 30.31. The average of fork length, GV and fertilization rate, that are important normative factors in breeding of sturgeon were 169.96,7.58 and %75.31 in Shahid Rajaii farm, 158.83,7.93 and %64.57 in Shahid Marjanii farm respectively and there was significant difference between two station (P<0.05). Correlation and regression between 15propagation normatives were statistically analyzed and discussed.
