Restoration Potential: Genetic differentiation among populations indicates that this species has low intrinsic rates of recolonization of rivers; combined with a low rate of population increase, this suggests that natural recolonization and population recovery may take decades or centuries (Waldman and Wirgin 1998).
Management Requirements: Hatchery-reared individuals have been released in the Hudson River (New York) and Nanticoke River, Chesapeake Bay (Welsh et al. 2002). Commerical fisheries in Chesapeake Bay caught 420 of 3,300 individuals released in the Nanticoke in the four years following the release (Welsh et al. 2002).

Management Research Needs: Current research focus: life history and population status studies, stock delineation, and development of culture and stock enhancement techniques (Smith and Clugston 1996).
Biological Research Needs: Determine specific habitat needs. Determine population numbers in coastal bays, estuaries, and rivers. Determine extent of threats. Continue study of the feasibility of hatchery culture and stocking in restoring populations.
