Most species of freshwater mussels must briefly parasitize a fish in order to complete their life cycle. Management of rare mussel species frequently demands knowledge of the mussel's fish host(s). Suitable fish hosts of Cyclonaias tuberculata, Lasmigona costata, and Ligumia recta were determined by artificially exposing fish species to mussel glochidia and then determining if juvenile mussels were produced. Fifty-one fish species were infested with C. tuberculata glochidia, but only the yellow bullhead (Ameiurus natalis) and channel catfish (Ictalurus punctatus) served as hosts. Six of eight fish species tested were found to be suitable hosts for Lasmigona costata: bowfin (Amia calva), northern pike (Esox lucius), bluegill (Lepomis macrochirus), largemouth bass (Micropterus salmoides), yellow perch (Perca flavescens) and walleye (Stizostedion vitreum). Juvenile Ligumia recta were collected from only two (largemouth bass and walleye) of thirteen fish species tested. Suitable fish hosts identified for C. tuberculata and Lasmigona costata were previously unknown. This is the first time the walleye has been identified as a suitable host for Ligumia recta.
