In commercial ichtyocomplex the roach prevailed (30-40% in general catches). Its size-gravimetric indexes were within the limits of optimum, and the 4-5th summer individuals were a population core. A bream in catches was 12%, basis of population included individuals of 4-5 years. Age composition of pike perch counted 12 classe and basis of population had 3-4th summer individuals. The rates of linear and gravimetric growth of pike perch are high satisfactory. The age composition composition of sazan is limited. The core of population consists of 3-5th years individuals. The rate of growth is satisfactory high. The epyzootic state of the Zaporozhian reservoir is characterized by the proof hearths of dyplostomoza and increase of extensiveness of fish infection with nematodes of Philometroides.
