Coastal Studies along with officials from the Massachusetts Department of Fish & Game are reminding boaters to use caution when transiting Cape Cod Bay due to an unusual concentration of right whales.
Recent aerial and vessel surveys have documented approximately 90 right whales throughout the bay.
Vessels strikes are a major cause of human-induced mortality for right whales, which are among the most endangered large whales in the world.
The state is advising boaters to reduce speed to less than 10 knots and post lookouts to avoid colliding with the whales. Boaters are also reminded that they are prohibited by state and federal law from approaching within 500 yards of a right whale.
Boaters should also report sightings of right whales immediately by calling the NOAA Fisheries Hotline at (866) 755-NOAA or hailing the Coast Guard on Channel 16.
