These whales are so decimated that a single birth was cheered by scientists

December 6, 2021 — In the ocean off South Carolina, researchers spotted something attached to Slalom the North Atlantic right whale, and for once, it was a good thing. She had a baby.

A sigh of relief spread across the community of Atlantic whale watchers who know critically endangered right whales are as likely to die as they are to give birth. On her path to motherhood at age 39, Slalom — named for a series of callous-like patches on her head that swoop like a ski slope — has survived at least six fishing net entanglements that are known to kill whales.

Over the past decade, the right whale population fell from more than 500 in 2010 to about 335, largely because of entanglements, boat strikes and slicing propellers. Fewer than 100 adult females remain. By comparison, endangered southern right whales that swim between Australia and South America number in the thousands.

“If you look at a graphic of what the North Atlantic right whale population looks like, it can seem like there’s no hope. It’s really alarming how quickly the population has declined in the last 10 years,” Philip Hamilton, a senior scientist for the New England Aquarium, said in an interview Friday.

Births among endangered right whales highest since 2015

April 5, 2021 — North Atlantic right whales gave birth over the winter in greater numbers than scientists have seen since 2015, an encouraging sign for researchers who became alarmed three years ago when the critically endangered species produced no known offspring at all.

Survey teams spotted 17 newborn right whale calves swimming with their mothers offshore between Florida and North Carolina from December through March. One of those calves soon died after being hit a boat, a reminder of the high death rate for right whales that experts fear is outpacing births.

The overall calf count equals the combined total for the previous three years. That includes the dismal 2018 calving season, when scientists saw zero right whale births for the first time in three decades. Still, researchers say greater numbers are needed in the coming years for North Atlantic right whales to rebound from an estimated population that’s dwindled to about 360.

“What we are seeing is what we hope will be the beginning of an upward climb in calving that’s going to continue for the next few years,” said Clay George, a wildlife biologist who oversees right whale surveys for the Georgia Department of Natural Resources. “They need to be producing about two dozen calves per year for the population to stabilize and continue to grow again.”

Cape scientists forge ahead with right whale research

April 7, 2020 — Over the past week, New England Aquarium scientist Philip Hamilton, manager of the right whale identification catalog at the aquarium’s Anderson Cabot Center for Ocean Life, has received photos of about 30 right whales taken by people walking the shoreline around Race Point and off Nahant.

Unfortunately, researchers hoping to see them from the air and sea during what they consider the epicenter of right whale migration into Cape Cod Bay essentially have been grounded by weather and coronavirus.

“We lost 22 days there,” said Charles “Stormy” Mayo, a senior scientist and director of the Right Whale Ecology Program at the Center for Coastal Studies in Provincetown.

COVID-19 fears forced the New England Aquarium to close March 13. Admission fees account for 80% of their $3.5 million in annual operating expenses, and the aquarium announced layoffs and furloughs last week to cut costs.

The Center for Coastal Studies did not lay off anyone, spokesperson Cathrine Macort said, but its offices and lab are closed. The center is watching expenses and applying for federal payroll aid.

Endangered right whales spotted in Cape Cod Bay during spring feeding season

April 6, 2020 — An increasing number of endangered North Atlantic right whales have been spotted feeding off of Massachusetts’ coast in recent weeks, a sign that spring is finally here, researchers at the New England Aquarium said.

The right whales live in shallow waters off the southeastern United States during late fall and winter, the aquarium said. After pregnant whales give birth to their calves while living with juvenile and male whales in the region during those months, the whales migrate to Cape Cod Bay during the spring to feed before heading further north.

“In a time when so much is changing around us, I find the appearance of right whales feeding in these waters as they have for hundreds, if not thousands, of years reassuring. Some ancient behaviors remain,” said Philip Hamilton, a research scientist with the Anderson Cabot Center for Ocean Life at the aquarium.

Dead whale found in LI waters was last seen caught in fishing line, NOAA says

September 20, 2019 — The North Atlantic right whale whose decomposed body was found floating in the waters off Fire Island earlier this week was seen alive last month caught up in fishing line, officials said.

Wounds likely inflicted by plastic rope confirmed he was the rare leviathan seen in the August video. Scientists had previously named him “Snake Eyes” for the twin eye-shaped scars on his head, said Philip Hamilton, a research scientist at Anderson Cabot for Ocean Life at Boston’s New England Aquarium.

The fishing line that may have ended the whale’s life — after he had swum in the Atlantic for more than four decades — ran through his mouth and possibly anchored his tail to the sea bed, Hamilton said.

Rescue team foiled in first attempt to disentangle right whale

July 11, 2019 — A North Atlantic right whale rescue mission has failed in its first attempt because of how difficult it is to track the endangered animals.

On Tuesday, the Campobello Whale Rescue Team headed out into the Gulf of St. Lawrence to try to locate and disentangle one of the three entangled North Atlantic right whales spotted in recent weeks.

Philip Hamilton, research scientist with the New England Aquarium, said the rescue team lost track of the whale because the plane that was monitoring it needed to refuel and had to go back to dry land.

“They didn’t have aerial support to help relocate the whale,” he said.

Scientists Sound Alarm After 6 Rare Whale Deaths in a Month

July 5, 2019 — A half-dozen North Atlantic right whales have died in the past month, leading scientists, government officials and conservationists to call for a swift response to protect the endangered species.

There are only a little more than 400 of the right whales left. All six of the dead whales have been found in the Gulf of St. Lawrence off Canada, and at least three appear to have died after they were hit by ships.

The deaths have led scientists to sound the alarm about a potentially catastrophic loss to the population. The deaths are especially troubling because they include females, said Philip Hamilton, research scientist with the Anderson Cabot Center for Ocean Life at the New England Aquarium.

“If we’re going to have deaths, they just can’t be female,” Hamilton said, adding the population is down to only about 100 reproductive females. “We need a different system.”

Right whales have suffered high mortality and poor reproduction in recent years, particularly in 2017. The whales appear to be traveling in different areas of the ocean than usual because of food availability, said Nick Record, senior research scientist at Bigelow Laboratory for Ocean Sciences in Maine.

‘Truly alarming’: No babies for endangered right whales

March 27, 2018 — SAVANNAH, Ga. — The winter calving season for critically endangered right whales has nearly ended with zero newborns spotted in the past four months — a reproductive drought that scientists who study the fragile species haven’t seen in three decades.

Survey flights to look for mother-and-calf pairs off the Atlantic coasts of Georgia and Florida are scheduled to wrap up when the month ends Saturday. Right whales typically give birth off the southeastern U.S. seacoast between December and late March. Researchers have recorded between one and 39 births each year since the flights began in 1989.

Now experts are looking at the possibility of a calving season without any confirmed births.

“It’s a pivotal moment for right whales,” said Barb Zoodsma, who oversees the right whale recovery program in the U.S. Southeast for the National Marine Fisheries Service. “If we don’t get serious and figure this out, it very well could be the beginning of the end.”

Zoodsma said she doesn’t expect any last-minute calf sightings this week.

The timing could hardly be worse. Scientists estimate only about 450 North Atlantic right whales remain, and the species suffered terribly in 2017. A total of 17 right whales washed up dead in the U.S. and Canada last year, far outpacing five births.

With no rebound in births this past winter, the overall population could shrink further in 2018. One right whale was found dead off the coast of Virginia in January.

“It is truly alarming,” said Philip Hamilton, a scientist at the New England Aquarium in Boston who has studied right whales for three decades. “Following a year of such high mortality, it’s clear the population can’t sustain that trajectory.”

Right whales have averaged about 17 births per year during the past three decades. Since 2012, all but two seasons have yielded below-average calf counts.

Scientists will be looking for newborn stragglers as the whales return to their feeding grounds off the northeastern U.S. this spring. That happened last year, when two previously unseen babies were spotted in Cape Cod Bay.

Right whale researcher Charles “Stormy” Mayo of the Center for Coastal Studies in Provincetown, Massachusetts, said he was hopeful some calves were born this season off the Carolinas or Virginia, where scientists weren’t really looking.

It’s also possible right whales could rally with a baby boom next year. Females typically take three years or longer between pregnancies, so births can fluctuate from year to year. The previous rock-bottom year for births — just one calf spotted in 2000 — was followed by 31 newborns in 2001, the second-best calving season on record.

Right whale survival may be dependent on snow crab fishery’s flexibility

March 22, 2018 — The future of the North Atlantic right whale is looking more and more bleak, and with their fate inextricably tied to the lobster and crab fishing grounds off the coast of Northern New England and Eastern Canada, pressure is mounting on the fisheries and their regulators to take more drastic action.

No right whale calves have been spotted so far this year – the latest in a string of bad news for the species, which lost 17 members in 2017. That total represented about four percent of its remaining population, and was around six times the normal mortality of the whales.  An eighteenth dead whale was found entangled in fishing gear off the coast of Virginia in January. Gear entanglement, followed by blunt force trauma caused by collisions with ships, have been identified as the main causes of these deaths.

Philip Hamilton, a research scientist at the Anderson Cabot Center for Ocean Life at the New England Aquarium, who studies the mammals, said there’s slim hope remaining that researchers have missed spotting any new calves.

“The calving season isn’t considered completely over – the folks who are doing the surveys on the calving grounds off of Florida and Georgia will be going for another month, but we’ve never gone this long and not found a calf,” Hamilton said. “And there are only a few whales that have not been seen, so we’re not particularly optimistic that a calf will be seen down there.”

With only an estimated 100 breeding females left in the entire North Atlantic right whale population, scientists are closely monitoring the changing reproductive cycle of the whales.

“We have had drops in reproduction in the past. We had a dip in the early 1990s and then a pretty dramatic downturn in the late 1990s that culminated with just a single right whale calf born in 2000. So we have seen this before, but we’ve never seen it in conjunction with such extremely high mortality,” Hamilton said.

In addition to the premature deaths and low birth rate, the right whale species faces the new and additional challenge of a lengthier gestation period. According to Hamilton,  their inter-birth interval has been increasing over the last five or six years, going from the standard of three to four years to 6.6 years in 2016, and jumping to an average of 10.2 years in 2017.

“There is a lot going on for them. We do know that females will forego reproduction if they aren’t in adequate body condition, meaning they have to have substantial fat reserves to support a calf. They end up losing up to a third of their body weight nursing a calf, so they have be able to handle that,” Hamilton said. “And there are a couple of factors which may be impacting female body condition. One would be food availability.”

The whales have been shifting where they feed in recent years and largely not going to some of their standard, historically productive feeding grounds like the Bay of Fundy and Roseway Basin and Great South channel east of Cape Cod. Instead, last year many ended up in Canada’s Gulf of St. Lawrence, where they are in much greater danger of entanglement with fishing gear, Hamilton said.

Whale deaths result in Canada’s snow crab fishery losing MSC certification

March 21, 2018 — Canada’s East Coast snow crab fishery has had its sustainable catch certification suspended by the Marine Stewardship Council, the organization announced on 20 March. Until another audit occurs in October 2018, some Maritime snow crab will not be able to display the MSC label.

The certification suspension is the result of incidents involving the deaths of 13 North Atlantic right whales in the Gulf of St. Lawrence in 2017. Necropsies showed that three of the whales died as the result of entanglement with crab gear. The audit also found that of a further five live entanglements, four were with crab gear.

Philip Hamilton, a research scientist at the Anderson Cabot Center for Ocean Life at the New England Aquarium, described last summer as the perfect storm when it came to right whale mortality. The whales appeared in waters where they have never been before and during a fishing season when there were more crab pots and rope in the water.

Peter Norsworthy, executive director of the Affiliation of Seafood Producers Association of Nova Scotia (ASPANS), said 2017 was an extraordinary year.

“It was a longer fishery last year because the quota was higher than it had ever been. So it took a lot longer to execute the fishery than it normally would. Normally, 75 percent of the catch is landed within the first three weeks. This year, the quota is going to be down to normal levels, about 25,000 tonnes vs last year’s 43,000 tonnes. So we fully expect it will be caught in a normal time period and finish by the end of May,” Norsworthy said. “Hopefully, with an earlier start we’ll get most of the fishing completed before the whales show up, if they show up again.”

Norsworthy said fishermen were unsure what the certification suspension will mean to individual fishermen in terms of catch prices. He said they will wait to see “how the market responds.”

“I think most buyers realize 2017 was an unusual circumstance and are fairly well-informed about what activities are being undertaken [to protect the whales],” he said.
