Right Whales Are Migrating
North Atlantic right whales are on the move along the Atlantic coast of the U.S. With an unprecedented 20 right whale deaths documented in 2017 and 2018, NOAA is cautioning boaters to give these endangered whales plenty of room. We are also asking commercial fishermen to be vigilant when maneuvering to avoid accidental collisions with whales, remove unused gear from the ocean to help avoid entanglements, and use vertical lines with required markings, weak links, and breaking strengths.
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 slightly more than 400 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.
