Commercial fish species helminthological study, its impact on the fish products quality and safety

A complete helminthological study of seven commercial fish species in the coastal waters of the city of Sevastopol was carried out. The goal is to study the fauna of helminths that are in biological relationships with commercial fish species, to assess the epizootic situation of commercial fish species living in the southern waters of Crimea. Tasks: collection of information about the species of helminths living in commercial fish species of the southern waters of the Crimea, in order to prevent their reproduction, assessing safety, possible harm and developing new methods for monitoring the safety of veterinary and sanitary examination. Instances for the survey were selected in the markets of Sevastopol. Research was carried out in the laboratory of the KubSAU of the city of Krasnodar. In this laboratory, a survey of 167 fish specimens belonging to seven key commercial species was carried out. 22 species of helminths were found in 7 examined fish species. Of these, 15 are sexually mature helminths, and 7 are in the larval stage of development. As a result of complete helminthological studies and a thorough analysis of the data obtained, it was revealed that the nematode Hysterothylacium aduncum has the greatest veterinary and veterinary-sanitary significance. The data obtained clearly confirm the need for a mandatory veterinary and sanitary examination in the places where commercial fish are caught and for further parasitological inspection, regardless of the epizootological state of the place or area. It is important to say that the veterinary and sanitary examination should be carried out and strictly monitored at all stages of implementation.
