In this study, host suitability for glochidia of the bivalve Anemina arcaeformis was tested in sh of 12 taxa in 4 families (Lethenteron sp. in Petromyzontidae; Carassius sp., Rhodeus ocellatus ocellatus, Opsariichthys platypus, Candidia sieboldii, Pseudorasbora parva, Gnathopogon elongatus elongatus, Biwia zezera, and Pseudogobio esocinus esocinus in Cyprinidae; Misgurnus anguillicaudatus and Cobitis spp. (C. biwae and C. minamorii tokaiensis) in Cobitidae, and Rhinogobius umineus in Gobiidae) by an arti cial infection experiment. Metamorphosed juveniles were obtained from 9 taxa. Juveniles could not be obtained from R. o. ocellatus, Carassius sp., and M. anguillicaudatus. The highest metamorphosis rates from parasitized larvae to juveniles was 30.3% in C. sieboldii, 23.5% in R. umineus, 16.8% in Cobitis spp., 13.6% in P. parva, 11.9% in O. platypus, 4.4% in Lethenteron sp., 2.8% in B. zezera, 2.1% in G. e. elongatus and 0.7% in P. e. esocinus. Only Rhinogobius spp. were previously known to be hosts of A. arcaeformis, so these represent new host sh.
