The abundance of the eastern oyster, Crassostrea virginica, in Maryland waters of Chesapeake Bay has been declining exponentially since the start of major commercial exploitation in the late 19th century (Kennedy and Breisch 1981; Rothschild et al. 1994; Jordan and Coakley 2004).

Eastern oysters, Crassostrea virginica Gmelin 1791, are common bivalves in West Atlantic estuaries. They build thick, predominantly calcitic shells used for protection against predators and environmental stressors such as extreme salinity or pollutants ( Davenport, 1985 ; Kennedy et al., 1996 ; Checa et al., 2007 ; Checa et al., 2009 ).
