The Freshwater Mollusk Conservation Center at Virginia Tech is a cooperative research and propagation facility to restore and recover endangered freshwater mollusks in Virginia and adjacent states. Beginning in 1978, the Virginia Cooperative Fish and Wildlife Research Unit, U.S. Geological Survey, began life history research on a suite of recently listed endangered mussels. Numerous graduate student theses and dissertations over roughly a 20-year period provided the knowledge and expertise to implement a propagation program. In 1997, the first propagated juveniles of a federally endangered species were released to augment reproduction in that population. In 2000, a grant from the National Fish and Wildlife Foundation and matching funds from other agencies enabled the center to construct a 2,700 foot building and pond complex to enhance its conservation work. Over the last 10 years, the annual production of juveniles has gradually increased, such that roughly 50,000-100,000 juveniles of 10-12 species are typically produced each year for release to natal rivers.
