Sharks and seals: A success story on Cape Cod

July 1, 2019 — Eighteen years ago, charter boat captain Joseph Fitzback and his customers held on tight as a 14-foot great white stripped a striped bass off a fishing line, then rocked the boat with a couple of exploratory bumps, 2 miles off Chatham’s Lighthouse Beach.

Television crews and reporters lined up to interview Fitzback, but as the numbers of seals, and the sharks pursuing them, have increased, such interactions are almost commonplace. In a relatively short time the Cape has evolved from ocean playground to wilderness experience, and today Fitzback’s story might get little more than a few hits on social media.

By now, the first of perhaps hundreds of great whites, the largest such aggregation on the East Coast, have returned to the Cape for the summer from their winter grounds to the south. They are hunting a gray seal population that has exploded from almost zero in the 1970s to nearly 30,000, possibly as many as 50,000, today, depending on the science you choose to believe.

MASSACHUSETTS: Seals on a comeback, attracting sharks

May 28, 2019 — Seals have rebounded to healthy numbers along Massachusetts’ shores after being nearly decimated by early settlers and a bounty that later wiped out tens of thousands of them, according to experts — and that is what is attracting sharks.

The National Oceanic and Atmospheric Administration estimates there are at least 27,000 gray seals and 75,000 harbor seals in U.S. waters during their breeding seasons.

“What we’re witnessing is a comeback to a really healthy marine environment,” said Kimberly Murray, seal program lead at NOAA Fisheries in Woods Hole.

The numbers are a stark contrast to the 1700s, when gray seals had been nearly wiped out during the first 100 years of New England settlement, said Tony LaCasse, a spokesman for the New England Aquarium in Boston.

By the late 1800s, the seals had rebounded, but conflicts with commercial fisheries and a desire for the seals’ meat and pelts led to a bounty on both gray and harbor seals from 1888 to 1962 in Massachusetts and Maine. During those years, as many as 135,000 seals were killed, Murray said.

“Seals were perceived as competitors to fisherman,” LaCasse said. “Fishermen would carry shotguns in their boats and shoot them on sight.”

After A Shark Attack, Addressing Cape Cod’s Growing Seal Population

October 10, 2018 — In the wake of the Cape’s first shark fatality, there have been increasing concerns about the seal population and its impact on tourism and the economy of fisheries, which leaves many people wondering — does Cape Cod have a seal problem?

Out at the Chatham Harbor fish pier, tourists gather on an observation deck to watch gray seals wait for scraps from nearby fishing boats. The spot is well-known amongst pinniped lovers like Debbie Hinds-Gale, a visitor from Syracuse, NY who returns to this place every year her family visits the Cape. She pointed out at a seal not far from the shore.

“There’s another one with its fins up, I think it’s fun when they lay on their backs like that and put their fins up in the air, it’s like they’re doing tricks for you,” she said, adding that she could watch them for hours. “To me it almost looks like a smaller manatee, but their faces, I think look like they’re between a dog and a horse face.”

But for others, the seals have become more than just adorable creatures to see on vacation. The Cape’s population of gray seals has grown dramatically in the past 20 years. For fisherman Mike Rathgeber who runs fishing tours out of Provincetown, the seals have become a nuisance.

NOAA officials say seal die-off linked to virus

September 24, 2018 — Gray and harbor seals have lured sharks in increasing numbers into Cape Cod waters, with tragic results, but the burgeoning seal population is taking a hit from viruses.

The National Oceanic and Atmospheric Administration has issued an unusual mortality event alert for both species of seal in the Gulf of Maine.

From July 1 to Aug. 29 (when the alert was issued) 599 seals were found dead (137) or ill and stranded (462) on New England shores. In the few weeks since that number has soared to 921. Most of those were in Maine (629), with 147 in New Hampshire and 125 in Massachusetts.

The dead or dying seals have been located mostly to the north but a couple were found as far south as Plymouth in Cape Cod Bay.

For comparison the nearly 500 seals found last month is roughly 10 times the number that stranded in August of 2017.

“That is attributed to the influences of disease,” noted Terri Rowles, NOAA’s Marine Mammal Health and Stranding Program coordinator.

Infected East Coast seals are washing ashore – and are a danger to people and pets, experts say

September 4, 2018 — Hundreds of East Coast seals are showing up, stranded on New England shores dead or sick.

Harbor and gray seals on the northern Atlantic Coast of the United States have tested positive for avian influenza, or bird flu, according to the National Oceanic and Atmospheric Administration’s fisheries. Others have tested positive for phocine distemper virus, similar to the virus dogs can contract and which has caused epidemics among seals in other parts of the world, killing thousands, according to the National Institutes of Health.

Both gray and harbor seals can range as far south as the Carolinas, where they sometimes travel during the winter months and haul themselves onto beaches to rest and soak up some sun.

The seals that end up stranded but alive are “in poor body condition with clinical signs of lethargy, coughing, sneezing and seizing,” according to NOAA. As of last week, 532 seals had washed up on the coasts of Maine, New Hampshire and Massachusetts. Of those, more than 400 were found dead.

Samples from those seals were sent to Tufts University and the University of California, Davis labs for testing, NOAA said. Samples tested “preliminarily positive” for either bird flu or the distemper virus. Four of the seals tested positive for both viruses.

Sharks should be happy about new Google Earth survey of seal populations

June 14, 2017 — Gray seals are booming. They’ve flocked to coastal Massachusetts, where hunters once killed the animals wholesale — a dead seal’s nose could fetch a $5 reward in the 1960s.

Twenty years ago, there were about 2,000 seals near Cape Cod and Nantucket. A new estimate, published Wednesday in the journal Bioscience, suggests there are now as many as 50,000.

‘‘We should be celebrating the recovery of gray seals as a conservation success,’’ said David Johnston, an author of the study and marine biologist at Duke University .

Where seals go, sharks often follow. Great white sightings in Cape Cod increased from 80 in 2014 to 147 in 2016. Johnston said the shark spike may be linked to the seals. ‘‘One of our tagged animals was killed by a white shark,’’ he said.

Maine and Massachusetts once placed bounties on seals because fishermen feared they would gobble up valuable fish such as cod. (There is little evidence that seals actually compete with fishermen, Johnston said.) The century-long bounty hunt claimed up to 135,000 animals.

The seals bounced back after 1972’s Marine Mammal Protection Act outlawed the killings. ‘‘I’m a firm believer if you just stop doing bad things to wildlife they will recover,’’ Johnston said. The seals’ recovery raised a question infrequently asked in conservation: What happens after success?

‘‘We haven’t done a great job of preparing people,’’ he said, ‘‘that they would be back again.’’

Part of that means quantifying the success. In 2011, a National Marine Fisheries Service aerial survey estimated 15,000 seals swam in southeastern Massachusetts waters.
