Abstract :

Regarding to the importance of morphometric and meristic factors of fish Categories, invironmental factors, feeding, growth and development, this research in order to scaling the morphometrics and meristics factors of Huso huso (male), Acipencer ruthenus (female) and their hybrid in1387 in Shahid Beheshti Center (sadde Sangar) has done. In this survey 90 numbers of 3-year-old fishes were experimented to determine 10morphometric factors (total length, head length, snout length, the length of back of the eyes to opercule, snout length till barble, snout length till nostrils, snout width in site of barbel, snout width in site of mouth, snout length till spiracle and the distance between eyes) and 7 meristic factors(the numbers of rays of pectoral and dorsal fins, the numbers of left and right lateral scutes, the numbers of left and right pelvic scutes. Statistical analysis expressed that parental species and hybrid have significant variation in all morphometric and meristic factors.
