The host species for glochidia of unionid mussels were examined in Lake Anenuma, Aomori Prefecture. As a result, Anemina arcaeformis was recorded for the first time from Aomori Prefecture and was found to infect two host fish species (Gymnogobius castaneus and Tribolodon hakonensis). Sinanodonta sp. was found to infect four species (Hypomesus nipponensis, G. castaneus, Tridentiger brevispinis and T. hakonensis); Hyriopsis schlegeli infects three species (H. nipponensis, G. castaneus and T. brevispinis), and Inversiunio jokohamensis also infects three species (G. castaneus T. brevispinis and T. hakonensis). The fish species composition was investigated and the prevalence of infection by unionid mussel glochidia for each host species in Lake Anenuma was investigated. Hypomesus nipponensis was the dominant fish species. Sinanodonta sp. mainly utilized H. nipponensis, A. arcaeformis utilized two species (G. castaneus and T. hakonensis), and the two other unionid species (H. schlegeli and I. jokohamensis) mainly utilized G. castaneus.
