Abstract
Length, age frequency, von Bertalanfi growth parameter, reproduction and absolute fecundity of two populations of killifish (Aphanius sophiae) from Cheshmeh-Ali of Damghan and Shour River of Eshtehard were studied monthly from October 2004 to November 2005. There was no significant difference between sex ratios of the two populations (X2=0.679, P=0.410). Age and length frequencies revealed that female fish of Cheshmeh-Ali were taller and longer-lived than those of Shour River. Maximum of Gonadosomatic index of Cheshmeh- Ali fish was in May while in the case of Shour River, it was in April. The absolute fecundity showed no significant difference using ANCOV A whereas egg diameter of Cheshmeh-Ali population was significantly bigger than Shour River population (P<0.001).
