The aim of the present study was to obtain a basic knowledge of the haematology and the influence of sex on some blood parameters of wild carp (Cyprinus carpio) spawners. Haematological indices [red blood cells (RBC), white blood cells, haemoglobin (Hb), packed cell volume (PCV), mean corpuscular volume (MCV), mean corpuscular hemoglobin (MCH), mean corpuscular hemoglobin concentration (MCHC) and leucocyte differential count] were measured in one blood sample from 24 females (weight, 1.3 ± 0.1 kg; length, 47.4 ± 1.06 cm) and 27 males (weight, 1.265 ± 0.105 kg; length, 46.9 ± 0.8 cm). The highest haematocrit (PCV), haemoglobin concentration (Hb), RBC, MCH and MCHC were found for males. The highest leucocyte differential were also found for females. Statistical analysis revealed that differences in haematological parameters between males and females fish were not significant.
