<p><span>In the early 1900s several hosts were identified for the black sandshell </span><i><span class="genus-species">Ligumia recta</span></i><span>. Recent attempts to propagate juvenile </span><span class="genus-species">L. recta</span><span> with two of the reported hosts (bluegill </span><i><span class="genus-species">Lepomis macrochirus</span></i><span><i> </i>and largemouth bass </span><i><span class="genus-species">Micropterus salmoides</span></i><span>) have produced inconsistent results and few juveniles. We conducted this study to determine which of the reported hosts or other fish hosts were the most suitable for glochidial metamorphosis. The duration of glochidial metamorphosis varied among seasons. Despite similar water temperatures, juveniles metamorphosed sooner and over a shorter period of time in the spring than early fall; the modal day of metamorphosis differed by 78 d. Relatively few juveniles were recovered from bluegill and largemouth bass in three trials. White crappie </span><i><span class="genus-species">Pomoxis annularis</span></i><span> and black crappie </span><i><span class="genus-species">P. nigromaculatus</span></i><span> were marginally suitable hosts. Although glochidia encysted on all hosts, >10× more juveniles metamorphosed on sauger </span><span class="genus-species">Stizostedion canadense</span><span> compared to other hosts tested.</span></p>
