Seals' Comeback Spells Trouble For Mass. Coast

Play associated audio

Before the Marine Mammal Protection Act was passed 40 years ago, early New Englanders had nearly hunted seals to death. They wanted them for their furs and to keep them from eating cod. Massachusetts even paid bounties on seals: $5 per nose.

The act has helped gray seals and harbor seals recolonize New England waters, but fishermen off the coast of Cape Cod say they have become a nuisance.

There's No Such Thing As A Free Lunch

A busy fishing harbor like the one in Chatham, Mass., is a swell place for the seals. Fisherman Sam Fuller says the lazy pinnipeds have learned to follow his boat like a chuck wagon, waiting for the crews to pull in nets full of fish.

"The seals just sit there and eat the fish out of the net as it's coming up into the boat," Fuller says.

Their sharp teeth also tear the nets, which can cost hundreds of dollars to replace.

The law that banned hunting the seals also bans any kind of harassing, so fishermen cannot shoo them away from their catch. Residents angry that their pricey beachfront property has become a favorite sunbathing spot for 300-pound sea mammals have their hands tied as well.

Ron Eppler, a dock worker, says fishermen should be able to do something about the problem. "If you own a ranch in Montana, and you've got a wolf problem or a coyote problem, you're allowed to protect your livestock," he says.

While the seals bug some locals, they are still a hit with tourists and children. "It's the busiest it's been," says Dylan Preston, an employee of Beachcomber Tours, who notes that seal watching boats have been selling out this summer. "I mean, sometimes we'll have seven to eight tours going out a day, which is pretty crazy. A good year, definitely."

Restoring Nature's Balance Has Consequences

But seals are also popular with bigger predators unconstrained by federal law. Last week, a family boating off Chatham saw a great white shark devouring a seal carcass. Last month, a swimmer was mauled by one.

Gregory Skomal, a state shark biologist, says the sharks are back because the prey is back.

"If you asked me in 2005, 'Why don't we know more about the great white shark?' I would have looked at you and said, 'Because I can't find it,' " Skomal says.

Stephanie Wood, a biologist with the National Marine Fisheries Service, says that the ecosystem is still finding a renewed balance. She says the seal population has tripled over the last dozen years, but will eventually level off.

"There's only so much food and space," Wood says. "But I don't think we have any specific idea of when seals in Massachusetts are going to reach carrying capacity."

An aerial survey last year counted 15,000 seals in Massachusetts waters. For John Our, a fishing boat captain in Chatham harbor, it is like competing with 15,000 fishermen who don't have limits. He is pessimistic about controlling the seals.

"It would take an act of Congress," Our says. "And there's not a congressman in his right mind that's going to be the first one out that says, 'Let's go harvest seals.' "
