Abstract
Species composition, prevalence, and intensities of species colonizing the northern stone crab Lithodes maia in Dalnezelenetskaya Bay (Barents Sea) were examined. Sixteen species attached to the body surface or the host gills were identified. The most common associates were hydrozoans (100.0%), especially Obelia longissima, and the amphipods Ischyrocerus commensalis (93.8%). Species composition of the stone crab epifauna was similar to that observed for the Lithodid crab Paralithodes camtschaticus, except that tubular polychaetes Pomatoceros triqueter and Placostegus tridentatus were found only on the surface of the stone crab, while fish leeches Johanssonia arctica occurred on the red king crabs. Differences in percentage of infested hosts, and mean intensities of some associates are influenced by the conditions of carapace structure and size of both crab species.
