The estimation of unsatisfactory of epizootic and morphophysiological condition of one- and two-year old bream in Volga-Caspian region is given. The results of helminthological, hematological and histological examination revealed the significant pathomorphological changes of tissues and organs of observed fish. Discovered abnormalities in the body of bream juveniles were induced by dangerous pollutants presenting in water and aggravated by the presence of abdominal parasites, namely tapeworms.
