Figure 8. Transformation of glochidia from Higgins’ eye pearlymussels at the Genoa National Fish Hatchery, Wisconsin. In mixing buckets, glochidia (top right) attach to the gills of host fish (middle left) and encyst (middle right). Host fish are placed in aquariums and glochidia transform, fall of the gills and settle to the bottom as juveniles. The juvenile shown in the lower right photo is approximately 0.75 millimeters long; it is shown next to the head of a pin for size comparison. (photos courtesy of the U.S. Fish and Wildlife Service)
