[ECOLOGICAL AND PARASITOLOGICAL CHARACTERISTICS OF THE SMALL REDFISH SEBASTES VIVIPARUS (PISCES: SCORPAENIDAE)].

Abstract

The results of the parasite fauna research represent peculiarities of formation and ecological, faunistic and zoogeographical characteristics of parasite fauna of the small redfish Sebastes viviparus Krayer. 1845. This species is distinguished among the other North Atlantic Sebastes by the richest fauna of myxosporidians, trematodes, nematodes and acanthocephalans. The parasite fauna of S. viviparus is formed mainly of boreal species and to a lesser extent of Arctic-boreal species. According to the vertical zonality of parasites in fishes of the North Atlantic they are mainly represented by mesobenthic and epicontinental species. The parasite fauna in small redfish possesses significantly more pronounced geographic specificity than that of other North Atlantic Sebastes species.
