Oxynoemacheilus kurdistanicus related to the Tigris and Euphrates basins and has been distributed in a wide range of Iran, Iraq and Turkey, There is limited information on the biology of this fish in Iranian waters. This study was carried out to evaluated growth pattern of this species with 209 fish samples that obtained from May up to October 2015 with Electroshocker devices. Sex ratio of male to female was 1: 0.62 that showed significant difference between sex ration of male to female in population (X2 = 11.49, p < 0.05). The weight - length relation of female was W = 0.0157 TL2.77 (r2 = 0.90) and the weight- length relation of male was W = 0.0127 TL2.86 (r2 = 0.93) and the total relation was W = 0.0141 TL2.81 (r2 = 0.98). The results showed positive allometric growth (t-test, tmale= 2.07, tfemale = 2.15, tpopulation= 3.33, p < 0.05).
