The University of North Carolina at Wilmington has ruled out exposure to toxic substances as the reason for a recent incident where hundreds of flounder and other fish, beached themselves on the Carolina coast. Both water and dead fish were tested and no toxins were found. Authorities feel like this was a classic "flounder walk" situation.
"A jubilee, also called a flounder walk, occurs when environmental factors such as calm winds and a salt wedge (high salinity waters pushing themselves up the river) combine to cause the oxygen levels to drop on the water bottom. The fish, seeking water with more oxygen, will move to the shallows, said Chris Batsavage, flounder biologist with the N.C. Division of Marine Fisheries."
