Summary. Commercial fishing in the Azov and Black Seas has always been and still remain to be one of the most important areas of the economy of the Russian Federation and Krasnodar region. Insufficient knowledge of the parasitic fauna of commercial fish in the coastal zone determines the relevance of research into the current composition of the parasitic fauna of these objects in the waters of Krasnodar region. Authors analyzed the parasitic fauna and epizootic situation in commercial fish species the habitat of which is the waters of the Azov and Black Seas. 35 species of parasites identified in 11 species of the commercial fish in the coastal zone of Krasnodar region during the conducted studies. The maximum indices of the invasion extent were revealed by trematodes in mullet, herring, horse mackerel, round goby - up to 88.8%, nematodes of mullet and pike perch - up to 75.5%, monogenia of mullet - up to 40%, myxosporidium of round goby - up to 50%. Based on the comparative analysis of the invasion, it was revealed that the parasitic fauna of the commercial fish, which were the object of study, is characterized by the dominance of trematodes. At the same time, myxosporidium and acanthocephala are the least represented. For the first time, the nematode Hysterotylacium aduncum and myxosporidium Kudoa nova were identified in the commercial fish in the waters of Krasnodar region. Quite high rates of parasitosis in the commercial fish in Krasnodar region are associated with the fact that pathogens of a number of infectious diseases are registered year-round in the form of carriage.
