Abstract

Age and growth of Chondrostoma meandrense Elvira 1987, were determined based on specimens collected from Kemer Reservoir, during the period from December 2004 to November 2005. Fork length ranged from 12.3 to 18.3 cm. The overall ratio of males to females was 1:2.38. The length-weight relationship for all samples was described by the following parameters: estimated as a=0.030 and b=2.706. Fish aged 2-6 years were found. The von Bertalanffy growth parameters for the whole population were: L∞:23.2 cm, W∞:148.19 g, k=0.118 year -1 and t0=-6.480 year. Growth performance index (Ф) was 1.80.
