Comparative analysis of some immunophysiological parameters of the pike Esox lucius (L.) and pike-perch Stizostedion lucioperca (L.) blood

The data on a number of immunophysiological indicators of pike and pike-perch from the Ry-binsk Reservoir are presented. Morphophysiological and some biochemical characteristics of the blood were significantly higher in the pike-perch, than in the pike. The analysis of the results sug-gests that the physiological parameters are more conditioned by the taxonomic position of fish, while the indicators of innate immunity – both cellular and humoral links – are more dependent on physiological state and conditions of fish habitats.
