Regional leaders say they won't roll out the welcome mat for an Asian oyster that had generated excitement among some seafood growers, saying it poses "unacceptable ecological risks" to the Chesapeake. After nearly five years of studying the risks and benefits of using the fast-growing Crassostrea ariakensis , state and federal officials say they will instead pursue an "all native" strategy to restore the commercial and ecological value of oysters in the Bay. As a result, after nearly 8 years of aquaculture studies, the last sterile nonnative oysters will be pulled from the Bay by the end of May. No further research with C.
The Chesapeake Bay, unlike many estuaries worldwide, has only one species of oyster, the native Eastern oyster Crassostrea virginica. Many other estuaries also have introduced or non-native oyster species. In most cases, those non-native species were introduced intentionally to supplement or replace a native oyster species for their fisheries value from aquaculture, as wild fisheries for the native oysters failed. Most of these introductions for aquaculture used the Pacific oyster Crassostrea gigas.
