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.

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.

NOAA Announces New Marine Mammal Stranding Response Organization in Nantucket

February 9, 2018 — The following was released by NOAA Fisheries:   

Today, NOAA Fisheries announces that Marine Mammal Rescue Nantucket is now an authorized marine mammal stranding response organization for Nantucket, Tuckernuck, and Muskeget Islands.

After four years of no stranding coverage on Nantucket and the outer islands, Marine Mammal Rescue Nantucket (known as MMRACK, after ACK – the call letters for Nantucket Airport) fills an important gap in the GARFO network. Led by Marine Mammal Alliance Nantucket CEO Scott Leonard, who spent more than a decade working as a stranding volunteer with New England Aquarium, MMRACK will respond to both live and dead whales, dolphins, and seals. In addition to assessing and providing transportation for animals in need of treatment, Leonard’s team, which consists of seasoned volunteers who have worked or trained with the New England Aquarium, will also perform necropsies (animal autopsies) on dead animals.

“Nantucket is a unique place with a rich marine mammal history,” says Leonard. “MMRACK’s mission is to provide public education and outreach with the focus on raising awareness of human and marine mammal interaction, while providing humane care to our marine species. We are looking forward to being part of the network, and plan on working closely with International Fund for Animal Welfare, Marine Mammals of Maine, U.S. Coast Guard, Massachusetts Environmental Police, and other regional partner organizations.”

NOAA Fisheries looks forward to working with MMRACK to increase stranding response capabilities on Nantucket, and to help with monitoring marine mammal populations and health.

“Nantucket is an important area for marine mammal populations, particularly gray seals that breed and pup there,” says Mendy Garron, NOAA Fisheries Greater Atlantic Region Marine Mammal Stranding Response Coordinator. “Having a stranding response organization on the island will help us track the health and welfare of these populations and help reduce conflicts through education and outreach.”

Please report stranded marine mammals on Nantucket, Tuckernuck, and Muskeget to the Marine Mammal Rescue Nantucket Hotline: 833-667-6626.

Right whale death off Virginia coast adds to concern about species’ demise

January 30, 2018 — The death of a right whale, spotted floating off the Virginia Beach coast last week, has drawn wide attention to a species considered one of the most imperiled of marine mammals.

The 10-year-old juvenile female is believed to have become entangled in fishing gear, and its death was the first of 2018 among North Atlantic right whales. The 39-foot whale was buried at Sandbridge’s Little Island Park beach after a necropsy Sunday involving experts from six institutions from Massachusetts to Florida.

Only about 450 of the whales are believed to exist after at least 17 deaths last year, and so far this winter no newborns have been spotted in the calving grounds off Florida and Georgia.

That has added to concern that the species’ demise might be accelerating. Some scientists have predicted that North Atlantic right whales could become extinct this century.

Earlier this month, the Center for Biological Diversity and two animal welfare groups sued the National Oceanic and Atmospheric Administration and its parent agency, claiming that they’re not enforcing laws and regulations meant to protect the whales from entanglement in lines for lobster traps and other fishing gear.

Jennifer Goebel, a spokeswoman for NOAA Fisheries, said the whale found dead near the North Carolina border was wrapped in line in a way that suggested it had been alive when it encountered the gear. She said officials will try to identify the line and who had deployed it.

Susan Larsen: What’s causing right whale decline?

January 30, 2018 — There is no argument that the North Atlantic Right Whale is in dire straits. Dr. Mark Baumgartner, a biologist from the Woods Hole Oceanographic Institute, gave a compelling presentation on “The Plight of the Right Whale” this past Tuesday evening, Jan. 23, at the Vineyard Gazette office. Since it was advertised, it was well attended.

One point of interest was that the right whales were making a healthy comeback, a two-decade period of modest annual growth; the population rebounded from 270 living whales in 1992 to 483 in 2010. From 2010, the numbers began to decline rapidly, with 2017 being a particularly devastating year, a loss of 17 whales. Dr. Baumgartner stressed the main focus was on whale entanglements with snow crab and lobster gear, and the urgent measures needed to be taken immediately within the fishery. Massachusetts fishermen are leading the way with break away links at the base of surface buoys (to 600lbs in 2001), sink rope (mandated in 2003), gear reductions and seasonal gear restrictions in Cape Cod Bay. He also touched on ship strikes as being a cause of death. However, the Marine Mammal Commission stated on their website, “other potential threats include spills of hazardous substances from ships or other sources, and noise from ships and industrial activities.”

But what Dr. Baumgartner could not explain was the scarcity of food that these leviathans need to feed on and their low birth rate. He showed the audience slides on the Calanus finmarchicus, known as copepods and remarked that this type plankton, sought after by these whales, are basically comprised of fat, or as Dr. Baumgartner called them “buttersticks.” Each adult whale needs to consume between 1,000-2,000 a day to remain healthy. The birth rate has dropped 40 percent from 2010-2016 and all five calves that were born in 2017 were to older mothers. “Since about 2011, we’re not seeing those sub-adults and juveniles in Florida and the question is, well, where are they?” asks Jim Hain, senior scientist at Associated Scientist at Woods Hole. Scott Kraus, a marine mammalogist from the New England Aquarium in Boston says, “Females are having young just every 9 years or more, compared with every 3 years in the 1980’s.”

Perhaps the decline is linked to the environmental disaster on April 20, 2010, the Deep Water Horizon oil spill in the Gulf of Mexico. From April 20, 2010, to July 15, 2010, more than 200 million gallons of oil spilled into the Gulf followed by another one million gallons of Corexit, a dispersant mixture of solvents and surfactants that break down the oil into tiny droplets. It is documented that for 3 months, marine microorganisms have ingested these toxins, which are carried along the Gulf Stream, a strong underwater current that flows through the Gulf of Mexico, skirts around Florida, flowing between Cuba and up the Eastern seaboard. Since the right whale gives birth off the coasts of Georgia and Florida, could these toxic chemicals be part of their decline?  “The chemicals in the oil product that move up through the food web are a great concern for us,” said Teri Rowles, coordinator of NOAA’s marine-mammal health and stranding response program. It is also documented that female mammals including humans who have been in contact with these toxins have suffered from irregular menstrual cycles, infertility, miscarriages and stillborns, along with premature aging and other debilitating side effects. John Pierce Wise Sr., co-author of the 2014 study and head of the Wise laboratory of Environment and Genetic Toxicology at the University of Southern Maine says, “To put it simply, after a sudden insult like an oil spill, once it’s over, it takes a long time for the population effects to fully show themselves.” This same article states “research has shown that the calves of other baleen whales (other than Bryde’s whale) may be particularly vulnerable to toxins that build in their tissues.”

A letter dated Aug. 17, 2017, from the office of the Massachusetts Attorney General in “Reference for information and comments of the 2019-2024 National Outer Continental Shelf Oil and Gas Leasing Program,” refers to the Deepwater Horizon disaster and its “harm to coastal communities and marine environment” and “long ranging impacts on marine mammals. The impacts on sea turtles could span the Atlantic.” The letter also states, “from 2010 through September 2016, there were 43 significant oil spills.”

In an article dated Dec. 5, 2017, ecologist Peter Corkeron of NOAA’s Northeast Fisheries Center in Woods Hole at the North Atlantic Right Whale Consortium’s annual meeting, “They’re (female right whales) dying too young, and they’re not having calves often enough.” This study found the females are struggling to reproduce. Dr. Baumgartner is the president of the North Atlantic Right Whale Consortium.

Canada announces changes to protect right whales

January 24, 2018 — NEW BRUNSWICK, Canada — Canadian officials announced new restrictions Tuesday on the amount of rope that snow crab fishermen can use in an ongoing effort to reduce the effect of fishing on the highly endangered North Atlantic right whale.

“We don’t want meters and meters of rope floating on the surface of the water,” Fisheries and Oceans Canada Minister Dominic LeBlanc said.

With 450 or fewer right whales remaining, after the death last year of 16 in Canadian and U.S. waters, and a possible 17th death still under review, pressure is increasing on two ways that humans cause right whale deaths: fishing gear entanglement and ship strikes. Last week, U.S. conservation groups sued the National Marine Fisheries Service to tighten restrictions on lobster fishing to protect the whales.

A roundtable on right whales, convened by LeBlanc last November, with fishing and marine business people, environmental groups, indigenous community members, scientists and Canadian and U.S. government officials, led to a more thorough understanding of the situation, according to a statement from the Fisheries Service and Oceans Canada.

LeBlanc’s announcement Tuesday was about four initial changes in snow crab fishing policy and practices to better protect right whales, 12 of which were documented as being found dead in the Gulf of St. Lawrence. More initiatives to limit entanglement and ship strikes are likely to come, he said.

Scientists: Maine coast could see more great white sharks

December 5, 2017 — PORTLAND, Maine — A great white shark detected in waters off Maine could be a sign that the big fish will become a more common sight in the years to come, say scientists who study sharks in New England.

White sharks are near the northern edge of their range along the Maine coast, though they are not commonly seen in the area. One of the sharks was spotted in the waters off Kennebunkport in the summer of 2016, sparking interest in finding out how many live off Maine.

University of New England marine scientist James Sulikowski has set out to answer that question, and he’s making his first findings public. Tracking devices discovered a different, 12-foot great white about 1.5 miles off of Old Orchard Beach in September of this year, he said.

New Method to Estimate Abundance/Detect Trends in North Atlantic Right Whales Confirms Recent Population Decline

Study confirms need for urgent action

September 22, 2017 — NOAA Fisheries researchers and colleagues at the New England Aquarium have developed a new model to improve estimates of abundance and population trends of endangered North Atlantic right whales, which have declined in numbers and productivity in recent years.  The findings were published in the journal Ecology and Evolution.

Between 1990 and 2010, the abundance of North Atlantic right whales increased just under three percent per year, from about 270 animals in 1990 to 482 in 2010. After relatively steady increases over that time, abundance has declined each year since 2010 to 458 animals in 2015.  The analysis shows that the probability that the population has declined since 2010 is estimated at 99.99 percent. Of particular concern is decline of adult females in the population, estimated at 200 in 2010 but 186 in 2015, the known deaths of 14 North Atlantic right whales this year, and the widening gap between numbers of males and females.

“Although our work directly reveals a relatively small decrease, the subtext is that this species is presently in dire straits,” said lead author Richard Pace.

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.
