Description: Results of the long-term helminthological study (2001-2013) of the Pacific salmons and migratory chars from the genus Salvelinus, held in the basins of the three largest salmon rivers of the northern part from the continental coast of the Sea of Okhotsk-Taui, Yama and Gizhiga, and in the coastal waters of Taui Bay, are generalized. In general 53 species of helminthes (43 genera, 30 families, 13 orders, 5 classes, 3 types - Plathelminthes, Nemathelminthes, Acanthocephales) and three species of parasitic crawfishes (2 genera, 2 families, 1 order of Crustacea class, Arthropoda type) were determined. According to number of species among helminthes trematodes dominate -24 species, 19 genera, 12 families, 5 orders, 1 class. The second and the third positions are taken by cestodes (11 species, 8 genera, 8 families, 2 orders, 1 class) and nematodes (11 species, 11 genera, 7 families, 3 orders, 1class). Acanthocephalans, while having low number of species (7), represent taxa of high rank (5 genera, 3 families, 3 orders, 2 classes of separate type). Correlation of helminthes according to ecological groups (fresh water and sea) is approximately as follows: 26 species of fresh water parasites (4 cestodae, 10 trematodae, 7 nematodae, 3 acanthocephalae and 2 copepodae), 29 of sea parasite (6, 14, 4, 4 and 1, correspondingly) and one species (Cestoda Diphyllobothrium luxi) of uncertain ecological status.From the scope of at least 20 species of helminthes, which have medicine and (or) veterinary relevance, or mar the marketable appearance of fish production, four were marked out and characterized (Diphyllobothrium luxi, Anisakis simplex, Pseudoterranova decipiens and Nybelinia surmenicola), as the most significant in practical aspect for populace of the northern coasts of the Sea of Okhotsk.
