THE RIAL FLORA AND THEIR POSSIBLE ASSOCIATION WITH SPOILAGE IN A VARIETY OF FRESH- WATER FISH: CYPRINUS CARPIO. VAR. COMMUNIS

Abstract

The bacteria from a variety of fresh - water fish, Cyprinus
carpio. var. communis, showed the presence of micrococci, Gram
positive and Gram negative rods. These have been characterised as
far as was possible. Of thirty-eight strains of bacteria used, only
six strains were considered as causing spoilage of fish flesh in
experiments where flesh was incubated with individual cultures of the
bacteria. These six strains had been found on the surface and/or
intestine of the fish and supports the suggestions that, after death,
invasion of flesh by bacteria from the surface and intestine could be
the cause of bacterial spoilage of fish.
