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.”

Shutdown Affecting Whale Rescues

January 24, 2019 — Rescuers who respond to distressed whales and other marine animals say the federal government shutdown is making it more difficult to do their work.

A network of rescue groups in the U.S. works with the National Oceanic and Atmospheric Administration to respond to marine mammals such as whales and seals when the animals are in trouble, such as when they are stranded on land or entangled in fishing gear. But the federal shutdown, which is entering its 33rd day on Wednesday, includes a shuttering of the NOAA operations the rescuers rely upon.

NOAA plays a role in preventing accidental whale deaths by doing things like tracking the animals, operating a hotline for mariners who find distressed whales and providing permits that allow the rescue groups to respond to emergencies. Those functions are disrupted or ground to a halt by the shutdown, and that’s bad news if whales need help, said Tony LaCasse, a spokesman for the New England Aquarium in Boston, which has a rescue operation.

“If it was very prolonged, then it would become problematic to respond to animals that are in the water,” LaCasse said. “And to be able to have a better handle on what is really going on.”

The shutdown is coming at a particularly dangerous time for the endangered North Atlantic right whale, which numbers about 411, said Regina Asmutis-Silvia, a senior biologist with Whale and Dolphin Conservation of Plymouth, Massachusetts. The whales are under tight scrutiny right now because of recent years of high mortality and poor reproduction.

Maine: Photos reveal multiple rare right whales off York County coast

May 16, 2018 — Scientists from the New England Aquarium have concluded that the endangered North Atlantic right whales spotted swimming and feeding off the coast of York County last weekend were not the same animal.

Tony LaCasse, spokesman for the New England Aquarium, which catalogs all right whales, said in a telephone interview Tuesday evening that the scientists used photographs to confirm that the right whale photographed off Long Sands Beach in York was right whale No. 1409.

A North Atlantic right whale spotted off the coast of Wells was a different whale, according to LaCasse.

The York whale is a male born in 1984. Its mother was known as No. 1160. Her death was confirmed in 2005 after her carcass was found floating offshore.

Whale No. 1409 “is definitely an adult male whose length is estimated at 45 feet and weighs around 90,000 pounds,” LaCasse said, dispelling reports from untrained observers that the whale was a juvenile. “The photograph was outstanding.”

Some right whales are assigned names. LaCasse said there is a right whale named Van Halen because the pattern on its forehead looks like an electric guitar.

A new model for right whale estimates

New system confirms population decline as another death is reported in Canada.

September 21, 2017 — NEW BRUNSWICK, Canada — Another North Atlantic right whale death in Canadian waters has brought further attention to the threat of fishing gear to the endangered marine mammals.

“It’s considered a severe entanglement,” New England Aquarium spokesman Tony LaCasse said of the dead female, believed to be around 3 years old. Fishing rope and gear, including a snow crab pot, entangled the pale, deeply cut carcass, estimated to be 36 feet long.

The right whales, which frequent Cape Cod waters in late winter and early spring, are among the rarest whales in the world, with 524 estimated in 2015 in a report by the North Atlantic Right Whale Consortium. The death brought the total fatalities this year to 14, representing about 3 percent of the population.

The carcass was spotted by airplane surveyors Friday off Miscou Island, New Brunswick. The dead whale was towed to the island Monday, and a necropsy was performed Tuesday.

“The key thing is that the animal was entangled,” said Tonya Wimmer of the Marine Animal Response Society in Halifax, Nova Scotia.

Color saving crustacean from pot

July 25, 2016 — When a local restaurant hosts a lobster party this weekend, it won’t be the usual bake with clams.

Instead s’mores will be served and a special crustacean will be freed from the eatery’s saltwater tank and returned to the sea.

Earlier this week, lobsterman Dean Mould was pulling traps aboard the FV Dominatrix, when he discovered something unusual. When he offloaded his catch at Capt. Joe & Sons on East Main Street, the prize landed there.

It was a blue lobster, a color that only one in 1 million to 2 million lobsters have, according to scientists. Tony LaCasse, a spokesman for the New England Aquarium, said the blue color may be due to genetics, or diet. Diet — a missing protein — is the more likely culprit when there is a bunch of blue lobsters caught in the same area, he said.

Lacasse says more blues have been popping up in the last three or four years, and blue is the most common of the unusual colors lobsters may show, with white being the rarest. “But it’s still pretty uncommon, and personally my favorite.”

Right Whale, Wrong Place

April 20, 2016 — Whale watchers spent the day yesterday in Nahant looking for Mr. Right.

A wayward North Atlantic right whale made a splash just off the shore for most of the afternoon.

The endangered species is known to hang out near Cape Cod Bay this time of year, according to Charles “Stormy” Mayo, senior scientist at the Center for Coastal Studies in Cape Cod and director of the right whale ecology program.

“Anytime a few whales go up the shore it’s really a special thing and a rare occasion,” he said. 
“Every time, in the case of the right whales, their travel depends on the concentration of food; they’re grazers.”

Mayo added he thinks the whale frolicking off Nahant is likely to return to the Cape, where there is the highest concentration of North Atlantic right whales. Fewer than 500 are thought to exist.
