[Further comment on the significance of data on fish parasites for related disciplines].

The significance of data on fish parasites was earlier considered by V. A. Dogel', S. S. Shul'man, S. M. Konovalov, and other Soviet parasitologists. These data are inadequately used by related disciplines. The possibility to use parasitological data for studying fish feeding pattern, peculiarities of their bathymetric distribution, migration routes, taxonomy, phylogenetic origin, and revealing the origin of marine basins and their ichthyofauna has been demonstrated.
