Flounder, Yellowtail – U.S. Atlantic

Yellowtail Flounder is a fast growing flatfish that produces many young and reaches a maximum size of 22 inches and 2 lbs. Yellowtail Flounder occur in the Northwest Atlantic from northern Newfoundland to the lower part of the Chesapeake Bay.

All Yellowtail Flounder populations are currently depleted and fished at too high a level. Bottom trawls are the primary fishing gear used to catch Yellowtail Flounder. Bottom trawls damage the seafloor and catch other depleted species. Some Yellowtail Flounder are also caught with gillnets. Gillnets sometimes catch marine mammals.
