ABSTRACT

Metabolic processes in fishes of the fam. Cyprinidae with different intensity of infestation by obligate symbionts − exo- and endoparasites under normal hydrochemical regime and high concentration of inorganic nitrogen compounds have been studied. Significant differences in hormonal regulation of metabolism and enzymatic activity of various tissues of the aquatic organisms under different endogenous (parasites) and exogenous (toxicant) influence were revealed.
