Overharvesting oysters did more than deplete the resource. Every time an oyster leaves the water, a piece of the habitat oysters and other Bay species need is also lost. Between 1980 and the time of the study three decades later, suitable habitat declined about 70 percent. The number of oysters were already falling rapidly by this time due to two diseases, Dermo and MSX, which started spreading through the Bay in the late 1950s and early 1960s.| University of Maryland Center for Environmental Science
