Gorchanok N. Veterinary-sanitarian examination and sanitary evaluation of fish in case of kudoosa

The dissertation is dedicated to improvement of the procedure of veterinary-sanitarian examination and sanitary evaluation of fish contaminated with miksosporidia of Kudoa genus. On the basis of obtained results scientific-methodological recommendations on sea and ocean fish kudoosa diagnosis and the procedure of its veterinary-sanitarian examination are elaborated and introduced for production and higher education. The level of extensity and intensity of the main industry fish species (Gobiidae, Merluccidae and Gadidae families) invasion with parasites of Kudoa genus is defined. Places of parasites' localization and their morphological peculiarities are determined. The scheme of detailed investigation of parasites of Kudoa genus is presented. The degree of bullhead N. melanostomus contamination according to the size and sex of fish, season and the area of investigation is determined. Organoleptic, chemical, microbiological, toxicological, radiological indices and biological value of fish, according toits contamination with Kudoa are studied. The influence of parasites on amino acids' and fatty acids' composition of fish meat is analyzed. Mutual relations in the system: parasite - host on the histological level is investigated.
