Abstract: 

In this study, 403 specimens gobiidae, Neogobius igorlap (105 females, and 298 males) were collected from 3 stations, Torkman Port, Miankale Peninsula and Gomishan from beach seine in fall, spring and winter, 2010. Results showed that collected samples had 0+-2+ years old. Sex ratio dominance was by males in different ages. The highest frequency was observed in 0+ years. The biggest female fish, had total length, 271 mm and body weight, 280.7gr and in male, 326 mm and 254.2gr. Condition factor was different in age’s groups and different seasons. However, relative characteristics; body height and width; head length, width and height; peduncle length and height, and distance between eyes were larger in Torkman station than other stations, but discriminant analysis (DA) determined low variance in distinguishing 3 groups. It seems, specimens are along to one population.
