COMPARATIVE PHYSIOLOGICAL ASSESSMENT OF COMMON CARP (CYPRINUS CARPIO) AND CRUCIAN CARP (CARASSIUS CARASSIUS) BASED ON ELECTROLYTE AND HEMATOLOGICAL ANALYSIS

Studies based on biochemical and hematological parameters in fish are significant in monitoring of health and early detection of pathological conditions. This research obtained values of serum electrolytes and hematological parameters in crucian carp (n = 15) and common carp (n = 13). Significantly different values of K, Cl and Ca concentration were detected. In serum of common carp there were significantly higher concentration of K and Cl and lower concentration of Ca, compared to the crucian carp. Hematological parameters differ in these two species. In blood of common carp significantly lower PCV, hemoglobin concentration, RBC and MCV and notably higher MCHC and WBC were obtained, compared to crucian carp. This preliminary research is important in establishing referential range of biochemical and hematological parameters in cyprinid fishes.
