In order to determine some hematological parameters of horse mackerel, Trachurus trachurus, sampling was conducted between April 2005 and March 2007 at the Dardanelles. Moreover, the effects of season, reproduction, sex, size, age, water temperature, and salinity on the horse mackerel hematologic parameters were investigated. The following annual averages were obtained for the hematological parameters: hematocrit ratio (Hct), females 38.0 +/- 0.32%, males 37.3 +/- 0.36%; hemoglobin level (Hb), females 12.8 +/- 0.13 g/100 mL, males 13.0 +/- 0.16 g/100 mL; erythrocyte (RBC) count, females 1050263.4 +/- 5857.20 mm(3), males 1046081.13 +/- 6319.89 mm(3); leukocyte (WBC) count, females 15797.4 +/- 259.11 mm(3), males 16545.0 +/- 354.54 mm(3); mean corpuscular volume (MCV), females 363.2 +/- 3.12 mu m(3), males 358.8 +/- 3.57 mu m(3); mean corpuscular hemoglobin (MCH), females 123.0 +/- 1.16 pg, males 124.3 +/- 1.48 pg; mean corpuscular hemoglobin concentration (MCHC), females 33.7 +/- 0.17 g/100 mL, males 34.8 +/- 0.22 g/100 mL. Hematological parameters differed significantly (P<0.05) between reproduction periods and between seasons. For both, male and female horse mackerel, the Hct, Hb, RBC, WBC, MCV, and MCH values increased significantly (P<0.05) with size and age. The WBC increased significantly (P<0.05) with increasing sea water temperature in both sexes. In this study, the reference values of hematological parameters were obtained and it was concluded that these parameters were affected by physiological (fish size, age, reproduction) and environmental (season, temperature) factors. Such factors as well as the reference values should be taken into consideration when hematologic studies for horse mackerel is to be conducted.
