Examining 213 bacteriological samples from 57 pike perch has revealed the high contamination of the fish with Enterobacteria in the branchia and intestine, which spread into the viscera and tissues. In the kidney there prevalent Escherichia coli (27.3%). Enterobacteria (20.), and Edvardsiella (16.6). The liver most commonly displayed yeasts and fungi (18.2%). Citrobacteria (14.3). Acinobacteria (14.3%). Many microbial strains had proteolytic and hemolytic activities and a considerable resistance to sodium chloride (7.5%). Acinobacteria, Providencia, and Proteus remain viable in its 10% solution. The findings suggest that the foods from the pike perch should undergo thermal treatment and a thorough bacteriological monitoring from its raw material to finished products to be made.

Enteric bacteria, such as Proteus, Citrobacter [correction of Cytobacter], and Providencia, were found to be prevalent particularly in the gills and intestines of marketable fishes of the Volga and Caspian Seas. Half of all the enteric bacteria was detected in the fish kidneys, spleen, and liver. This shows it necessary to standardize different types of fish raw materials.
