The article discusses a study which examined in vitro proteolytic and amylolytic activities of microflora from the intestinal tract of adult roach Rutilus rutilus which feed mainly on mollusks and macrophytes. 60 strains of bacteria were isolated from the intestinal tract of the roach. The dominant group of the isolates in all parts of intestine were strains of Aeromonas. Proteolytically active strains of bacteria were plenty in the midgut. Amylolytically active isolates were found in the bacteria in the foregut, midgut and hindgut. All parts of the digestive tract of roach were colonized by active protease and amylase producers.
