Abstract
Modern forms of pond fish farming provide for compacted planting of fish in ponds.
This causes close contact of farmed fish and favorable conditions for the spread of diseases. Most
often carp fish get sick. A veterinary and sanitary examination of fish caught from the ponds of the
Institute of Fish Farming and Biserovskiy fish plant cages was carried out according to organoleptic
and bacteriological indicators. An autopsy of the fish was carried out in order to identify endoparasites,
ectoparasites and changes in internal organs.
As a result of the veterinary and sanitary examination, inflammation of the swim bladder was
noted in some fish on the basis of clinical data and parasitological research. No parasites were found.
No significant changes were registered during the organoleptic examination. In sick fish, when cooking,
there was a slight turbidity and a decrease in the size of fat droplets on the surface of the broth.
Bacterioscopic examination of carp revealed gram-negative bacterium aeromonas hydrophila, which
causes aeromonosis. Recommendations for the prevention of inflammation of the swim bladder and
aeromonosis are given.
