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=0.0146×L2.934. Munro’s phi prime index was estimated as 1.95, L∞ as 26.42 cm W∞ 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. CP - IRAN IN - LG - eng PB - IFRO PG - 827 PT - Orginal research papers YR - 2016
