April 7, 2017 — While the first day of the U.S. Marine Mammal Commission’s annual meeting, held for the first time on Cape Cod, dealt with threats to a tiny Mexican porpoise and massive Arctic polar bears, Thursday’s sessions brought the focus home with a profoundly local subject: gray seals.
“These animals are reassuming their ecological roles,” said David Johnston, an assistant professor at Duke University. “And people freak out.”
Seals are back in force, with between 30,000 and 50,000 living in the waters of Southeastern Massachusetts, primarily on and around Cape Cod, according to a new estimate produced by Johnston to be published in an upcoming report. Feelings about their return, however, are decidedly mixed.
After seal hunts and bounties exterminated gray seals from New England by the mid to late 60s, few imagined they would come back, certainly not to the point where tens of thousands now inhabit the Cape and surrounding waters.
Fishermen complain about seals taking their catch, boats run into them, some question their effect on water quality or their potential to spread disease, and raise concerns about the threat of a rapidly expanding great white shark population, visiting Cape waters to dine on blubber.
