No such thing as 100%

The Washington Post has an interesting article about plans in Maryland and Virginia to release Asian Suminoe oysters, to replace the dwindling stocks of native species. Some of the oysters (Crassostrea ariakensis) are from populations bred with an extra chromosome, and while this is supposed to make them sterile, it is not 100% effective. Experiments are already underway to test the oysters' ability to thrive in the Atlantic Ocean. Meanwhile, some officials are concerned about the potential of these bivalves to introduce disease or to become invasive themselves. Bonus points to the Post for using the scientific name of the oyster.
