Karyotype analysis was performed in Chalcalburnus mossulensis (Heckel, 1843) belonging to the carp family by investigating the number and structures of their chromosomes. The fish used in this study were caught with fishing nets from Kizilirmak river and taken to the laboratory. They received an abdominal injection of 0.6 mg colchicine (Colchicum Dispert) dissolved in 1 ml of distilled water per 1 g body weight. As a result of the C-metaphase investigation, it was determined that C. mossulensis had 2n=48 chromosomes. Their karyotypes were determined to be composed of 6 metacentric, 10 submetacentric, and 8 acrocentric chromosome pairs. We were unable to identify any sex-related chromosomes in this species.
