Ecologo-immunophysiological characteristic of chub Leuciscus cephalus (L.) lving in river ecosystems of the Caucasus

Abstract

The results of a study on some parameters of innate immunity and oxidative processes in hepatopancreas of the chub Leuciscus cephalus (L.) inhabiting the river ecosystems of Krasnodar krai and Abkhasia subjected to different degrees of anthropogenic load are presented. Antimicrobial properties of blood serum, the content of nonspecific immune complexes in the liver, and the level of total lipids and antioxidant activity have been studied. It is determined that the portion of immunodeficient specimens is higher in samples from polluted waters than from unpolluted areas. Fishes caught in the river subjected to high anthropogenic load contained higher concentrations of products of lipid peroxidation and immune complexes and had lower levels of antioxidants.
