ABSTRACT. Pikeperch culture is a new direction in European aquaculture. There is scant knowledge of pikeperch physiology, especially regarding hematological and biochemical parameters in the blood. This study examines selected hematological parameters in the blood and the biochemical parameters in the plasma of pikeperch from intensive culture. To determine the hematological parameters, blood was drawn from 20 healthy fish, weighing 40-50 g. The red blood cell count (RBC), hematocrit (Ht), hemoglobin (Hb), various leukocyte counts, the total leukocyte level and MCV, MHC and MCHC counts were examined. The AST, ALT, ALP, plasma bilirubin, cholesterol, glucose, urea and total protein level were determined in the blood plasma. The analyses of the results suggest that pikeperch have similar hematological and biochemical parameters to rainbow trout. The results of this preliminary study indicate that fish from this new intensive culture were in good condition without any symptoms of diseases.
