Title Of Article :
Age and Growth Features of Chondrostoma regium (Heckel, 1843) from Almus Dam Lake, Turkey
Abstract :
Chondrostoma regium (Heckel, 1843) samples (n=359) were collected from Almus Dam Lake (Tokat) between March 2006 and April 2007 in order to estimate age and growth properties. Total lengths of specimens ranged from 13.7 cm to 28.1 cm and weights ranged from 19 g to 240 g. The overall ratio of females to males was 1:0.66. Ages of fish varied between 1-6 years. The von Bertalanffy growth parameters were L∞ = 33.50 cm, k = 0.219 year-1 and t0 = -2.369 year for females, and L∞ = 27.50 cm, k =0.397 year-1 and t0 = -1.455 year for males. The length-weight relationship was found as W = 0.0036 TL3.316 in females and W = 0.0038 TL3.269 in males. The growth performance index (Ф ) values of females, males and entire samples were 2.391, 2.477 and 2.407, respectively. The relative condition factor value was 1.006 for entire population.
