ABSTRACT
Studies were carried out on the survival of six strains of bacteria: Pseudomonas fluorescens, Pseudomonas aeruginosa, Escherichia coli, Streptococcus faecalis, Bacillus subtilis and Bacillus cereus in fish feeds stored for 72 days in -11°C, 5°C and 20°C.
On the last day of the study live cells of all bacterial strains were found in the feed stored in -11°C, of three strains in 5°C and two in 20°C.
Two strains, Bacillus subtilis and Bacillus cereus survived throughout the whole storage period in all three temperatures.
