DOI : 10.17693/yunusae.v15i21956.235766 Viewed : 4270 - Downloaded : 2364 In this study, the age, sex, length and weight distributions, growth, length-weight relationship and condition factor of chub from Keban Dam Lake have been determined. The total of 102 specimens were analyzed between April and November 2009. Sex composition of population was 59.80 % female and 40.20 % male. The von Bertalanffy growth equations were found as Lt= 45.96[1-e–0.2121(t+1.2636)] for females and Lt= 44.33[1-e–0.2420(t+1.0128)] for males. Length-weight relationships were estimated as W=0.0087 L 3.1419 for females, W=0.0091 L 3.1121 for males and W=0.0084 L 3.1484 for all individuals. Condition factors of the population were calculated between 0.9325 and 1.8484 Keywords : Chub, Squalius cephalus, growth properties, Keban Dam Lake, Turkey
