The article reviews the diseases of cyprinid fish in the farm quarantined for aeromonosis and inflammation of the swim bladder. The etiology and symptoms of the disease are considered, and the pathoanatomical changes in fish. Modern methods of control and treatment of each age category of reared objects are considered. Preventive therapeutic feeding of farmed fish, vaccination, summer drying of ponds are offered. A veterinary and sanitary assessment of the farmed fish is given. Sick fish, if it has not lost its marketable appearance and meets the nutritional qualities, are allowed to eat people without restrictions. Non-market fish is sent to feed farm animals, poultry, fur-bearing animals in a boiled form or processed into fish flour. It is recommended to pay more attention to ecological methods of combating fish diseases – the use of polyculture for the effective production of marketable products (marketable fish); to increase the non-specific resistance of fish with probiotics; to use immunological methods, such as vaccination.
The objects of this research were the mirror carp and trout growth in fishfactory «Biserovskiy ». The purpose of this research was veterinary and sanitary estimation of these fish. We conducted a pathoanatomic autopsy and inspection of fish, determined organoleptic characteristics and conducted microbiological investigation on the presence of coliforms (E. coli), Listeria monocytogenes, S. aureus in the fish. Veterinary-sanitary examination was conducted in accordance with the reference book «Veterinary and sanitary examination of freshwater fish» and «The rules of veterinary and sanitary examination of freshwater fish and crawfish». Microbiological investigation was conducted in accordance with «Instruction of sanitary and microbiological control of alimentary products from fish and marine invertebrates», GOST 26670-91 «Food products. Methods for cultivation of microorganisms», GOST 10444.15-94 «Food products. Methods for determination of quantity of mesophilic aerobes and facultative anaerobes», GOST 31747-2012 «Food products. Methods for detection and quantity determination of coliformes », GOST 32031-2012 «Food products. Methods for detection of Listeria monocytogenes », GOST 31746-2012 «Food products. Methods for detection and quantity determination of coagulase-positive staphylococci and Staphylococcus aureus». According to the results of the research, these fish met the requirements of regulatory documentation, which confirms the safety of products for the consumer. Keywords: fish farming, mirrorcarp, trout, pathological investigation, organoleptic investigation, microbiological investigation, veterinary and sanitary examination.
