Veterinary and Sanitary Examination of Omul (Coregonus Autumnalis(Pallas, 1776)), Caught During the Feeding Period and Spawning Migration in the Lena River Basin in the Comparative Aspect

The article considers the veterinary and sanitary assessment of the quality of the Arctic (Arctic Sea) omul Coregonus autumnalis(Pallas,1776), caught during the feeding period from the Laptev Sea, Taimylyr village and extracted during the spawning migration from the Lena river, near the village of Kyusyur Bulunsky ulus of the Republic of Sakha (Yakutia) in a comparative analysis. In the external examination determined by organoleptic indicators: status, scales, mouth, eye condition and cornea of the gills (colour), smell of fish, as fins, the texture of the muscles, condition of the abdominal cavity, of internal organs, determined the quality of the broth when boiling the sample (transparency and flavour). Physical and chemical parameters of fish meat samples were determined by the pH value, reaction to peroxidase, content of aminoammiacic nitrogen, reaction to copper sulphate, reaction to free ammonia (Eber’s test). Bacterioscopic studies of fish for freshness were carried out, microbiological indicators were determined: Quantity of Mesophilic Aerobic and Facultative Anaerobic Microorganisms (QMAFAnM), Escherichia coli (coliform), Staphylococcus(S. aureus), pathogenic microorganisms, including Salmonella. Parasitological studies of fish were carried out by the method of cutting in layers with compliance with regulatory documents. The parameters of the Arctic omul of different places of catch were determined by the fishing length, body height, head length, and mass of the fish carcass. According to the results of the veterinary and sanitary study, it was established that the arctic omul of the Bulunsky region, according to its organoleptic, physicochemical, bacterioscopic, microbiological and parasitological indicators, belongs to fresh, benign fish and is subject to free sale to the trade network for the population. The research data showed that the Arctic omul caught from the Laptev Sea, Taimylyr settlement, Bulunsky district, in terms of the parameters - body length, body length, head length, weight exceeds the size of omul caught from the Lena River, Kyusyur settlement.
