First dead endangered right whale of 2019 spotted in Canada waters

June 6, 2019 — The first dead critically endangered North Atlantic right whale of 2019 has been spotted in Canada’s Gulf of Saint Lawrence, the fisheries and oceans department said Wednesday.

The ministry said in a release that the animal carcass had been spotted drifting in the channel during an aerial surveillance flight on June 4.

“We are currently assessing the recovery and necropsy options,” it said.

The Canadian government stepped up tracking of right whales after more than a dozen were found dead in 2017 in the busy seaway and off the coast of New England in the United States, which had prompted concern from marine biologists.

Warmed waters linked to diminished food for right whales

June 4, 2019 — Overheated waters pouring into the Gulf of Maine from deep ocean reserves along the Atlantic coast appear to be diminishing the food supply on which North Atlantic right whales rely.

A new report from Oceanography says warming temperatures in the gulf are impacting densities of zooplankton, which the whales rely on for food.

The rapid pace of change near the Bay of Fundy, in particular, now indicates that traditional methods of protecting the whales, including protecting their decadeslong feeding areas, may need to be refined.

“Climate change is outdating many of our conservation and management efforts,” said the report’s lead author, Nicholas Record, a senior research scientist at the Bigelow Laboratory for Ocean Sciences in East Boothbay, Maine.

Weighing in on whales: Maine’s delegation asks for accuracy

May 31, 2019 — Maine’s congressional delegation issued a letter this week to NOAA’s acting director in an effort to clarify the agency’s mission and goals for right whale protections.

Maine’s lobster industry stakeholders have concerns about the federal data tool used to establish levels of risk, varying standards for risk reduction, and sharing the burden of whale protection by enlisting Canadian fisheries to adopt similar management measures.

Following an April meeting of the Atlantic Large Whale Take Reduction Team, Maine lobster officials agreed to reduce vertical trap lines by 50 percent and overall risk to right whales by 60 percent, with the understanding that other state-run fisheries would make the same commitment to overall risk reduction.

Maine’s congressional delegation asks feds to reduce impact of right whale protections on lobster industry

May 30, 2019 — Maine’s congressional delegation wrote Tuesday to federal officials to express concern that ongoing efforts to decrease the death of right whales will have a significant impact on Maine’s lobster industry.

The delegation asked National Oceanic and Atmospheric Administration leaders to ensure that decisions made by the Atlantic Large Whale Take Reduction Team are based on “sound” and “comprehensive” science, that risk reduction standards are equitable across the United States and Canada, and that the lobster industry is consulted throughout the decision-making process, according to a release from Maine’s four members of Congress.

The new efforts to protect right whales are driven by the federal Endangered Species Act and the Marine Mammal Protection Act. Because of the current endangered status of right whales, if Maine fails to come up with a plan to protect the whales, NOAA will determine what action is taken, according to Patrick Keliher, commissioner of the Maine Department of Marine Resources.

The task force set a goal of reducing right whale mortality by 60 percent to 80 percent, and met last month with a group of approximately 60 fishermen, scientists and conservationists joining state and federal officials to discuss ways to further reduce serious injury and mortality of endangered North Atlantic right whales caused by trap/pot fishing gear.

They hope to agree on measures that would reduce serious injuries and deaths of right whales caused by fishing gear in U.S. waters from Maine to Florida to fewer than one whale per year, the level prescribed by the Marine Mammal Protection Act, according to NOAA.

MICHAEL MOORE & HANNAH MYERS: High-tech fishing gear could save right whales

May 29, 2019 — Many fish, marine mammals and seabirds that inhabit the world’s oceans are critically endangered, but few are as close to the brink as the North Atlantic right whale (Eubalaena glacialis). Only about 411 of these whales exist today, and at their current rate of decline, they could become extinct within our lifetimes.

From 1980 through about 2010, conservation efforts focused mainly on protecting whales from being struck by ships. Federal regulations helped reduce vessel collisions and supported a slight rebound in right whale numbers.

But at the same time, growing numbers of right whales died after becoming entangled in lobster and crab fishing gear. This may have happened because fishing ropes became stronger, and both whales and fishermen shifted their ranges so that areas of overlap increased. Entanglement has caused 80% of diagnosed mortalities since 2010, and the population has taken a significant downward turn.

This comes after a millennium of whaling that decimated the right whale population, reducing it from perhaps between 10,000 to 20,000 to a few hundred animals today. And entanglement deaths are much more inhumane than harpoons. A whaler’s explosive harpoon kills quickly, compared to months of drawn-out pain and debilitation caused by seemingly harmless fishing lines. We believe these deaths can be prevented by working with the trap fishing industries to adopt ropeless fishing gear — but North Atlantic right whales are running out of time.

Link To Stress, Health Of Whales Might Be In Giant Mouths

May 29, 2019 — Whale researchers in New England believe they’ve found a new way to measure the amount of stress felt by whales when they experience traumas such as entanglements in fishing gear, and they say the technique could help protect the massive sea creatures from extinction.

The scientists, with the New England Aquarium in Boston, said the method involves measuring stress hormones by studying baleen, the bristly filter-feeding system in the mouths of the biggest whales on the planet. The baleen serves as a record that shows a spike in stress hormones when whales encounter threats such as a changing climate, ship strikes and entanglements, lead author Rosalind Rolland said.

Scientists can use the data to read the stress levels a whale experiences over the course of many years, somewhat similar to reading the rings on a tree. The data is important because whales experiencing more chronic stress are less likely to reproduce, and they can become more susceptible to disease — a bad combination for populations that are perilously low.

“A whale responding to any type of stressor could be interacting with a ship. It could be fishing gear. It could be environmental changes that stress the whale out,” Rolland said in a telephone interview. “This shows the stress hormones are related to what was going on with the whale.”

Tally of endangered right whale calves spotted so far this year increases to seven

May 28, 2019 — Seven North Atlantic right whale calves have been spotted off the coast of the United States so far in 2019 – a positive development for the critically endangered species, according to a recent report from CBC News.

Last year, no new North Atlantic right whale calves were born, and the overall population for the species was estimated to be just 411 individuals. The increased presence of calves this year is encouraging for research scientists like Garry Stenson, who heads the Department of Fisheries and Oceans (DFO) marine mammal division in Canada.

“It’s really nice to start seeing that we’re getting more calves,” Stenson told CBC News. “It’s gonna take a lot more before we’re gonna be feeling at all comfortable, but it does help to have some. It’s a much better view than what we had last year.”

Plane surveillance carried out this month revealed that North Atlantic right whales have returned to Canadian waters earlier than usual this year, arriving in late May instead of the typical June, the DFO said.

One of the world’s three right whale populations, North Atlantic right whales usually spend their winters in warmer waters nearby Florida and Georgia before migrating to New England and the Canadian Maritimes for the summer. In years past during this migration, entanglements in fishing lines deployed by lobster and crab fishing operations and ship strikes have resulted in several whale deaths. In 2017, 17 right whales died from ship strikes or entanglements in fishing gear, and in 2018, an additional three right whales died from similar causes.

Where Did the Right Whales Go?

May 23, 2019 — Something happened to the population of North Atlantic right whales in the last decade, as their numbers shrank and fewer calves were born.

Scientists had long speculated that a change had occurred in the whales’ sources of food. By 2017, only 411 animals were counted, down from 482 in 2010. A paper published this month in the journal Oceanography, links warming in the Gulf of Maine with the life cycle of the copepod Calanus finmarchicus, a tiny shrimplike creature that forms the foundation of the right whale diet.

Although it is hard to prove cause and effect, the paper’s lead author, Nicholas Record, said the study connected “the big ocean-scale climate changes” in the North Atlantic with the water coming into the Gulf of Maine and the whale’s food resources.

“All of these pieces lined up together really well,” said Dr. Record, senior research scientist at the Bigelow Laboratory for Ocean Sciences, a nonprofit institute in Boothbay, Maine. “It was really kind of stunning.”

An influx of warm water near the ocean floor in 2010 significantly reduced the abundance of the shrimplike creature in the Gulf of Maine that summer and fall. Warmer water would have brought in fewer Calanus and also meant that more died and were eaten earlier in the season, Dr. Record said, leaving less food, “right when right whales need their last big meal before winter.”

The whales followed the Calanus populations elsewhere, including to Cape Cod Bay and to the Gulf of St. Lawrence in northern Canada. Their shift in location may have created even bigger problems for the overall population, when they might have been hungry and moved to places with heavy shipping traffic.

Vineyard Wind seeks help in protecting right whales

May 23, 2019 — The company preparing to build an 84-turbine wind farm off Martha’s Vineyard has put out a call  to universities, technology companies and other innovators that could help implement a system to detect the presence of endangered North Atlantic right whales during construction.

Vineyard Wind said it is seeking a firm or institution that can “provide and operationalize enhanced acoustic monitoring systems that will detect the presence of Right Whales, and transmit information in real-time to project staff so that enhanced protections can be effectively implemented.”

Protection would include vessel speed restrictions, Vineyard Wind said.

Utility companies and the state tapped Vineyard Wind to construct an 800-megawatt wind farm 15 miles south of Martha’s Vineyard and 34 miles from the mainland to fulfill the first half of a 1,600-megawatt procurement called for in a 2016 clean energy law.

The company has already entered an agreement with a number of organizations to protect the whales.

BANGOR DAILY NEWS: Better information needed as Maine lobstermen take on challenge of protecting right whales

May 21, 2019 — In the early 2000s, the news appeared good for endangered North Atlantic right whales. Their population grew significantly, due to both rising numbers of births and fewer deaths from ship strikes and entanglements in fishing gear.

That good news has come to an end. Twenty of the rare whales died in just two years — 2017 and 2018, according to the North Atlantic Right Whale Consortium. For the first time in nearly four decades of monitoring, it appears no right whale calves were born last year.

The consortium estimates there are only 411 right whales off the Atlantic coast.

Given these dire numbers, U.S. fisheries regulators have proposed dramatic declines in the amount of fishing lines in waters where the whales are believed to congregate and pass through.

Last month, a team devoted to reducing right whale deaths told Maine officials that the state must reduce the risk it poses to right whales by 60 percent.

The team recommended that Maine’s lobster fishery cut the number of vertical lines in the water by half. Vertical lines run between traps and buoys on the surface of the water to mark their location. The recommendations will be turned into proposed federal rules, which will be subject to public comments. The process could take up to two years.
