NOAA Fisheries announces the annual opening of a Seasonal Management Area (SMA) in the Great South Channel to protect North Atlantic right whales starting on April 1, 2025. 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 Great South Channel SMA is in effect through July 31, 2025.
