Mid-Atlantic Seasonal Management Areas in Effect to Protect North Atlantic Right Whales

NOAA Fisheries announces the annual opening of Seasonal Management Areas (SMAs) in the Mid-Atlantic to protect North Atlantic right whales starting tomorrow, November 1,  2022. All vessels 65 feet or longer must travel at 10 knots or less in this area to reduce the threat of vessel collisions with these endangered whales. The Mid-Atlantic SMA is in effect through April 30, 2023.

Because vessels of all sizes can strike and injure a right whale, NOAA Fisheries also encourages vessels less than 65 feet in length to slow down to 10 knots or less within active SMAs.
