Life history characteristics we examined in 92 specimens collected from the Gharachay River. In july and January of 2011 and October of 2012. Sampling was by Electroshoker.Observed maximum age was +4 years in female. Sex Ratio (male: female) was 1:0/73, and length –weight relationships were BW=35/55.TL 32 in male and BW=14/8TL-30/7 in female. Mean egg diameter (ED) was 0/8726 0/12mm ranging from 0/67 to 1/1 mm. Mean absolute (AF)and relative. Fecundity (RF) were 4917/2157 ( 1690/04 SE) egg/female and 69/1( 16/15SE) eggs.g-1 body weight, respectively. AF and ED were found to increase significantly with increasing fish size, wherease RF increased significantly with both fish TL and weight.
