Some Growth Parameters of Chub (Squalius cephalus) Living in Uzunçayır Dam Lake (Tunceli-Turkey)

This study was carried out in Uzunçayır Dam Lake between May 2011 and September 2012. A total of 334 specimens (169 male, 161 female and 4 juvenile) of Squalius cephalus (Linnaeus, 1758), which ranged between 0-XI age groups, were investigated in study and male/female ratio was determined to be 1:0.95. Total length values ranged from 13.00 to 36.20 cm for males, from 13.60 to 33.80 cm for females; weight values ranged from 25.82 to 616.00 g for males, from 22.10 to 494.00 g for females; condition factor values ranged from 1.041 to 1.233 for males and from 0.890 to 1.298 for females. Length-weight relationship equation was determined as W= 0.0073TL3.1357 (R2=0.95) for all population. The von Bertalanffy growth parameters of population were calculated as L∞=40.29 cm, K=0.16 year-1, t0=-1.76 year, W∞=800.46 g
