Özet
In this study, 317 rudds (Scardinius erythrophthalmus (Linnaeus, 1758) were captured between March 2005 - January 2007 from Omerli Reservoir and growth features such as age, growth and condition factor were investigated. The age composition of rudd population varied between -0-8 years. Maximum number of rudds were 2 years of age. Females, males, and juvenile composition of the population was 54.26%, 43.22%, and 2.2%, respectively. The total length and weight of rudds varied between 6.8-29.0 cm and 3.4-392.7 g respectively. The von Bertalanffy growth equations were L(t) = 34.63[1-e(-0.170) ((t+1.327))], W(t) = 574.31[1-e(-0.170 (t+1.327))](3.15 +/- 0.029) for males, L(t) = 37.43[1-e(-0.153 (t+1.371))], W(t) = 847.58[1-e(-0.153 (t+1.371))] (3.28 +/- 0.024) for females and L(t) = 37.55[1-e(-0.153 (t+1.389))], W(t) = 819.23[1-e(-0.153 (t+1.389))](3.2 4 +/- 0.017) for all specimens in the Omerli Reservoir. Length-weight relationship was calculated as W = 0.0066TL(3.24 +/- 0.017) for all individuals. According to age groups, condition factor varied between 1.121-1.678 for females and 1.172-1.724 for males, respectively.
