‘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.

Path to extinction for North Atlantic right whales

March 26, 2018, PROVINCETOWN, Mass. — Inside the cabin of the research vessel Shearwater, Charles “Stormy” Mayo, senior scientist and director of the Right Whale Ecology Program at the Center for Coastal Studies, pulled up on his computer an image of the family tree of North Atlantic right whale #1140.

This whale — dubbed “Wart” by researchers — has a file of photographs, identifying marks, and a life history, as does nearly every one of the remaining 451 right whales on earth.

“Her productivity has been extraordinary,” Mayo said. But Wart hasn’t been seen since 2014, and some worry her fabled life may have come to an end.

Last summer was particularly tragic with 16, possibly 17, right whales — 4 percent of the remaining population — killed after being hit by ships, entangled in fishing gear, and other unknown causes.

Extinction, experts say, is suddenly a reality.

“It was one of the big stories of the day, that right whales were coming back,” Mayo said. “But up to 2010, you had this appallingly slow climb, then decline. Now we have a species that is clearly headed for extinction.”

Wart, first seen in 1981, at the dawn of right whale research, has been subsequently spotted and identified 66 times from the Bay of Fundy to Florida. Believed to be in her 50s now, she is one of the more successful breeders — mother to seven calves, grandmother to 13 and great-grandmother to six.

But that productivity may not be enough in the face of a host of environmental issues related to an increasingly urbanized ocean — vessel noise, pollution and oil and gas exploration — and the unknown complications from a rapidly warming sea that could affect, for example, the seasonal timing of critical right whale food.

Then, there is the intractable problem of human induced mortality and serious injury.

Sixteen deaths last summer caused many to hit the panic button. Researcher Brian Sharp called it shocking.

“It begs the need for fishery managers, the industry and scientists to push harder to find solutions,” said Sharp, manager of Marine Mammal Rescue and Research at the International Fund for Animal Welfare in Yarmouth.

Twelve of last year’s deaths occurred in the Gulf of St. Lawrence, where right whales had been seen sporadically over the last four decades, fewer than a dozen a year, and not well-documented. Five live entanglements also were documented in that area last year. Unlike the U.S., Canada has had no ship or fishing restrictions in place as the numbers of whales documented in the Gulf, possibly following prey driven north by climate change, has grown.

But four deaths also happened in the U.S. last year, despite decades of research and planning on how to create whale-safe fishing gear, massive fishing closures and rerouted and slowed ships to avoid fatal interactions with whales. The U.S. deaths alone were four times the number scientists set as the maximum allowed per year if the species is going to recover.

“There’s a huge misconception that the industry is not sensitive to this matter or not aware of it. We certainly are, and it concerns the industry a lot,” said Grant Moore, of Westport, a longtime offshore lobsterman and president of the Atlantic Offshore Lobstermen’s Association.

The exact number of North Atlantic right whales that existed prior to human killing is unknown, but the population was likely reduced to fewer than 100 by the time the international 1935 ban on whaling was enacted.

NOAA Announces Right Whale Speed Restriction Zone Off Nantucket

March 23, 2018 — NANTUCKET, Mass. — In an effort to protect critically endangered North Atlantic right whales, NOAA Fisheries has implemented a voluntary vessel speed restriction zone off Nantucket.

The Dynamic Management Area 11 miles southwest of the island was established after six whales were spotted in the area on Tuesday.

Mariners are asked to avoid the area or travel at speeds of 10 knots or less through April 4.

At least 18 of the whales died over the last year and the population is estimated to be around 430.

Gloucester Times: Cooperation needed to save endangered whales

March 23, 2018 — These are dire times for the North Atlantic right whale.

A record number of the whales — 17 — died due to ship strikes or gear entanglements last year. Meanwhile, scientists who have been tracking the mammals noted the birth of a mere five calves over the same period. The troubling trend does not bode well for the species.

“The story is just a simple one of arithmetic,” Charles “Stormy” Mayo, director of the right whale ecology program at the Center for Coast Studies, told Public Radio International. “If you have fewer births and higher mortalities, extinction is around the corner.”

It doesn’t have to be this way. Right whales, docile creatures that grow to about 50 feet long and about 70 tons, at one time seemed to be one of the conservation movement’s greatest success stories. The creatures — hunted nearly to extinction in the whaling era — saw their numbers grow from fewer than 250 to the current estimate of 450 after two decades of conservation efforts on the part of the federal government and the fishing and shipping industries.

The measures that worked before, however, are no longer sufficient to keep the species healthy. This is in large part due to the fractured nature of their habitat, which runs from the southeastern United States to Nova Scotia.

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.

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.

NOAA closes areas to protect whales

March 20, 2018 — As NOAA Fisheries continues to address the rising peril to whales in coastal waters stretching from New England to Florida, it is reminding local fishermen of current or impending gear closures off Massachusetts.

The closures, primarily around Cape Cod and in Cape Cod Bay, are part of NOAA Fisheries’ Atlantic large whale take reduction plan developed to provide increased protection to several species of whales — particularly the endangered North Atlantic right whales whose population continues to plummet.

Some of the gear closures impact trap and pot fishermen, while other impact gillnetters.

The closures have been greatly enlarged as part of a 2015 amendment to the large whale take reduction plan, according to Mike Asaro, the Gloucester-based marine mammal and sea turtle branch chief for NOAA Fisheries.

“The Cape Cod Bay closure has been greatly expanded northward and out beyond the outer Cape toward Nantucket,” Asaro said.

The closest closure to Cape Ann is the Massachusetts Restricted Area that encircles Cape Cod, with its northwest corner approaching the southern end of Cape Ann. The area is closed to all trap and pot fishing until April 30.

The Great South Channel restricted area, which sits to the east and southeast of Cape Cod, will be closed to all trap and pot fishing from April 30 until June 30. The Great South Channel also will be closed to all gillnetting during the same time.

Gillnetters also will be prohibited from fishing in the Cape Cod Bay restricted area until May 15.

Asaro said the closures are just one element in NOAA Fisheries’ strategy for mitigating dangers to the whales from gear and other man-made obstacles in the ocean’s waters.

Low Numbers of Endangered Whales Sparks Debate About Whether Lobster Industry Threatens Species

March 9, 2018 — The population of the endangered North Atlantic right whale took a big hit last year with a record number found dead in Canadian waters from ship strikes and entanglements. With this year’s calving season ending and no new births observed, an ongoing debate over whether Maine’s lobster industry poses a mortal threat to the species is gaining new urgency.

Woods Hole Oceanographic Institution scientist Mark Baumgartner says that to help the whales survive much longer, the ropes Maine lobstermen use to tend their traps have to be modified or even eliminated. And it’s not just for the whales’ sake.

“I feel the industry is in jeopardy,” Baumgartner says.

Baumgartner was at the Fishermen’s Forum in Rockland late last week to detail the whale’s plight. If the lobster industry doesn’t respond effectively, he says, the federal government will step in.

“As the population continues to decline and pressure is put on the government to do something about it, then they’re going to turn to closures, because that’s all they’ll have,” he says.

There were about 450 North Atlantic right whales estimated to be alive in 2016. There were only five calves born last year, and a record 17 deaths caused by entanglement or ship strikes.

Climate change threatens coastal life as we know it

March 9, 2018 — The Gulf of Maine is getting warm — quick. From 2004–2013, sea temperatures there rose faster than almost any other location on Earth.

Why it matters: The Gulf is home to a number of endangered species, and the fisheries there bring in several billion dollars per year to the U.S. and Canada, but the Gulf’s future hangs in the balance. Researchers are scrambling to understand what the warming water means for the people and animals who rely on the ecosystem, particularly as the changes there provide a glimpse into the future of coastlines around the world.

Why it’s warming

The Gulf of Maine lies at the intersection of several major ocean currents, including the Atlantic meridional overturning circulation, which moves dense, cold water down and toward the equator. Fresh water from melting sea ice seems to be weakening this current, which could be causing the Gulf to warm faster than other regions.

A combination of cold winters, warm summers, and dramatic tides make the Gulf one of the most productive ecosystems in the ocean. It’s a critical habitat for right whales, seabirds like puffins, humpback whales, bluefin tuna and other species.

Gear is in wrong place for right whales, scientists say

March 7, 2018 — ROCKPORT, Maine — Last summer, at least 17 endangered North Atlantic right whales died during their northwards migration from their spawning grounds off the coast of Florida and Georgia. Of those, 12 were found dead in Canadian waters, while five were found off the coast of the United States.

Besides the whales that died last year, several more were found entangled in fishing gear, and at least one more whale died in January of this year.

Now scientists and fisheries regulators are working to find ways to reduce the risk of entanglement. They may implement changes in fishing rules that have an enormous impact on Maine’s lobster industry.

The NOAA Fisheries Large Whale Take Reduction Team recently established separate working groups to study two proposals to reduce the risk of entanglement: splicing several 1,700-pound breaking strength “weak link” sleeves into vertical lines such as those that connect lobster buoys to traps; and removing those ropes altogether by requiring the use “ropeless” fishing gear.

Those working groups will focus on whether either solution is technologically feasible, whether it will actually work for fishermen, and whether it can be cost effective for fishermen.

According to scientists from NOAA Fisheries and the New England Aquarium in Boston, the evidence suggests that the already tiny right whale population is declining.
