Abstract

Current study was carried out between March 2019 and February 2020 to determine the biological characteristics of Cyprinus carpio, which is brought to fish markets of Alaca (Çorum) from Hasan Uğurlu Dam Reservoir (Samsun). Total, fork, standard lengths, and weights of 406 individuals were measured and recorded. Sex ratio was calculated as 1:2.1 (♀:♂). Ages were determined by using lateral scales and thus age groups were formed. According to the data collected, equation of length-weight relationship was and an isometric growth pattern was observed for combined individuals. VI age group has the most individuals (n=148). Fulton’s condition factor (K) and phi-prime growth index (Φ’) were calculated as 1.3 and 2.42, respectively. This study makes a contribution to common carp stock related studies for further common carp fishery management.
