Our state's oyster supply, keep in mind, is currently running at only 1 percent of its historic high. We really need oysters. They serve as a "filter" and help clean the Chesapeake Bay. Two hundred years ago, our state's plentiful oysters could filter the water of the entire bay in just three days. Today, we don't have enough oysters to satisfy our state's oyster lovers, let alone enough to clean the bay.
