Mid-Atlantic Seasonal Management Area in Effect November 1-April 30

NOAA Fisheries announces the annual opening of Seasonal Management Areas (SMAs) in the Mid-Atlantic to protect North Atlantic right whales starting on November 1, 2023. 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 SMAs are in effect through April 30, 2024.

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.

Details and graphics of all of all vessel strike management zones currently in effect.

Give Right Whales Room

North Atlantic right whales are on the move along the Atlantic coast of the U.S. If seen, remember that approaching a right whale closer than 500 yards is a violation of federal and state law.

Right Whales in Trouble

North Atlantic right whales are protected under the U.S. Endangered Species Act and the Marine Mammal Protection Act. Scientists estimate there are fewer than 350 individuals remaining, making them one of the rarest marine mammals in the world.

In August 2017, NOAA Fisheries declared the increase in right whale mortalities an “Unusual Mortality Event,” which helps the agency direct additional scientific and financial resources to investigating, understanding, and reducing the mortalities in partnership with the Marine Mammal Stranding Network, Canada’s Department of Fisheries and Oceans, and outside experts from the scientific research community.
