Recently Gavins Point NFH began an experiment aimed at developing a potential recovery program. Genoa NFH provided a female black sandshell mussel and the hatchery's aim was to see if flathead chubs (a local minnow species) would work as a host fish for the larval (glochidia) phase of the mussel's life cycle.
