Many people are familiar with the Chestnut blight attack that lead to the near extinction of the important American Chestnut Tree, a disaster that may have been one of the worst ecological tragedies to have struck the US in the twentieth century.
The blight was caused by the introduction of parasite infected Asian Chestnut trees, ostensibly to "improve" the American fruit, the Chestnuts.
In case we haven't learned our lesson, apparently some propose to introduce the Asian oyster to the Chesapeake Bay.
"NEWPORT NEWS, Va. - A 30-month fact-finding experiment will examine how Asian oysters grow, perform and survive in the Chesapeake Bay.
Researchers with the Virginia Institute of Marine Science and the University of Maryland will place thousands of the exotic oyster species in cages in the bay at four sites, two in Maryland and two in Virginia.
The scientists want to see how the Asian oysters compete with native oysters, whether they survive diseases that have ravaged the native stocks and how they grow amid predators in a real-world setting on the bottom of the bay.
Results from the study, to cost at least $721,000, will help determine whether Virginia and Maryland should be allowed to introduce Asian oysters into the bay as a way to restore a wild population...
