ПАРАЗИТОЛОГИЯ, 51, 1, 2017 УДК 639.2/.3; 595.133 INFECTION OF THE PACIFIC SAURY COLOLABIS SAIRA BY ACANTHOCEPHALANS IN THE KURIL ISLANDS AREA © I. I. Gordeev,* I. V. Grigorov, P. K. Afanasyev Russian Federal Research Institute of Fisheries and Oceanography V. Krasnoselskaya Str. 17, Moscow, 107104 * E-mail: gordeev@vniro.ru Submitted 06.05.2016 The Pacific saury Cololabis saira (Brevoort, 1856) is one of the important target species of commercial fisheries. <...> Food manufacturers and consumers encounter problems due to the infection of the saury by acanthocephalans, which are quite difficult to clean out completely during on-board catch processing. <...> Infection of C. saira was not studied on a regular basis, therefore, our knowledge about the parasites of saury is fragmentary. <...> This paper contains infection indices (only acanthocephalans) of the Pacific saury caught in the Kuril Islands area (Russian Exclusive Economic Zone) in 2015. <...> Красносельская ул., 17, Москва, 107140 * E-mail: gordeev@vniro.ru Поступила 06.05.2016 Тихоокеанская сайра Cololabis saira (Brevoort, 1856)—один из наиболее важных видов промыслового рыболовства. <...> Ключевые слова: Cololabis saira, тихоокеанская сайра, Acanthocephala, Rhadinorhynchus. 51 The Pacific saury Cololabis saira (Brevoort, 1856) (Beloniformes: Scomberesocidae) is a very popular food product that can be found in several cuisines of the Pacific countries and is one of the important target species of commercial fisheries in the Northern Pacific. <...> The presence of parasites, even dead and non-pathogenic ones, causes a significant deterioration in canned and chilled saury, affecting their marketable condition and raising concern among health authorities (Mikulich, 2014; Baryshko, 2015). <...> This research is aimed to study the infection rate of the C. saira by acanthocephalans and identification the areas where the helminth infection is the lowest, for the benefit of fisheries and consumers. <...> MATERIAL AND METHODS R R R R Fishes were caught by the fishing vessel «Sterlyad», which was fishing for Pacific saury in the Kuril Islands area (40°37 —41°15 N; 148°17 —149°40 E) using luring lights and stick-held dip nets. <...> All of the fish specimens were caught near the surface, over depths of 5320—5456 m, in four localities sufficiently <...>
