This study was carried out to determine population structure, growth and reproduction properties of barbel. A total of 198 individuals were sampled. Ages of samples were found between I and VI years, fork lengths between 4.3 and 16.6 cm and total weights between 1.2 and 65.8 g. Length-weight relationship was calculated as W=0.0146xL(2.934). Munro's phi prime index was estimated as 1.95, L-infinity as 26.42 cm W-infinity as 216.92 g, and condition factor as 1.265 +/- 0.01. First sexual maturation was determined in 6.0-6.9 cm group males, and second sexual maturity was recorded in 10.0-10.9 cm-group females. Individual fecundity was defined between 568 and 4171 eggs/female and relative fecundity was calculated as 64964.55 +/- 5855.49 eggs/kg female. Barbel did not show good growth and reproduction performance in the stream, because of fishing pressure.
