Capoeta buhsei is native species in the Namak Lake basin and biological aspects of life history of this fish in Iranian waters is not very well known. Life history of this fish examined by collecting 92 samples in Gharachay River. Sampling done by using Electroshoker in July and January 2011 and October 2012. The maximum age was found +4 years in female. Sex Ratio (male: female) was 1:0.73, and length –weight relationship was BW=35.55.TL3.2 in male and BW=14.8. TL3.07 in female. Mean egg diameter (ED) was 0.87260.12 mm ranging from 0.67 to 1.1 mm. Mean absolute (AF) and relative fecundity (RF) were 4917.2157 (1690.04 SE) egg female-1 and 69.1 (16.15 SE) eggs g-1 body weight, respectively.
AF and ED were found to increase significantly with increasing fish size, whereas RF increased significantly with both fish TL and weight.
