What makes some oysters more resilient than others?

(Louisiana State University) Louisiana oysters from the Gulf of Mexico may experience some of the lowest salinity in the world due to the influx of fresh water from the Mississippi River. In addition, increased rainfall and large-scale river diversions for coastal protection will bring more fresh water that does not bode well for the eastern oyster. New research published this week reveals new information on why some oysters may be more resilient to freshwater than others.
