NEFMC: Response to Study on Rising Water Temps in the Gulf of Maine

October 29, 2015  — The following was released by the New England Fishery Management Council:

The Gulf of Maine, located off northern New England and Canada, has hosted important commercial and recreational marine fisheries for centuries. In addition to existing threats from land-based pollution, marine discharges, energy development, and disturbances to habitat, a more recent problem, temperature rise, has emerged. The just-published paper in Science —Slow Adaptation in the Face of Rapid Warming Leads to the Collapse of Atlantic Cod in the Gulf of Maine — adds to the increasing body of work on this topic.

As an organization responsible for the management of fisheries in federal waters that encompass the Gulf of Maine, the New England Fishery Management Council (Council), along with partners, NOAA Fisheries and the New England states, offers comments on this paper.

  • Most importantly, climate change is a very real issue that affects fisheries in ways we are just beginning to understand and is one the Council and others must confront.
  • This particular paper presents interesting research, but as is generally the case, it is rare that any one scientific study provides “The Answer.” This one will almost certainly generate more discussion and further consideration of how fisheries management bodies might respond.
  • NOAA’s Northeast Fisheries Science Center is actively investigating climate change that could help develop possible responses. The Science paper will likely become part of the larger discussion on how to adapt and respond to climate change. During that process, it will be the subject of careful review, including testing of its assumptions and conclusions. Should they stand up to this scrutiny, the work may influence future quota-setting
  • Work is underway by the Council to look more broadly at fisheries through ecosystem-based fisheries management; those efforts may illuminate the way in which we consider this pressing threat to the productivity of fisheries in the Gulf of Maine and elsewhere.
  • More critically, the Science paper appears to presume that the Council should have anticipated the unusual temperature rise in 2012, without any explanation of how that could have been done. The current quota for Gulf of Maine cod is the lowest on record, and will almost certainly remain so in the foreseeable future. The goal at this time is to allow sustainable levels of fishing on healthy stocks, such as haddock, redfish, and pollock to continue, while creating the opportunity for cod to recover.

After reviewing the paper, Council Executive Director Tom Nies summarized his reaction to the challenges raised in the Science paper. “Fishery managers will need to adapt to the host of significant changes caused by the rapid rise in water temperatures in the Gulf of Maine; specifically, the New England Council will continue its close partnership with the scientific community in order to mount an effective response to this circumstance.”

Scientists: Warming Ocean Factor in Collapse of Cod Fishery

October 29, 2015 — PORTLAND, Maine (AP) — The rapid warming of waters off New England is a key factor in the collapse of the region’s cod fishery, and changes to the species’ management are needed to save one of America’s oldest industries, according to a report published Thursday in Science magazine.

Fishery managers say cod spawning in the Gulf of Maine — a key fishing area between Cape Cod and Canada that touches Massachusetts, Maine and New Hampshire — is only about 3 percent of sustainable levels, and participants in the fishery that dates to the Colonial era face dramatic quota cuts as a result.

The scientists behind the Science report say the warming of the Gulf of Maine, which accelerated from 2004 to 2013, reduced cod’s capacity to rebound from fishing pressure. The report gives credence to the idea — supported by advocacy groups, fishing managers and even some fishermen — that climate change has played a role in cod’s collapse.

The lead author of the study, Andrew Pershing of the Gulf of Maine Research Institute in Portland, said the gulf is warming at a rate 99 percent faster than anywhere else in the world, and as a result, too many of the fish aren’t living past age 4 or 5. Cod can live to be older than 20.

“Every animal has a temperature range that they prefer. The Gulf of Maine, for cod, is really at the warm end of that,” Pershing said. “If you warm it, you push it somewhere that’s really uncomfortable.”

Invasive species exploit a warming Gulf of Maine, sometimes with destructive results

October 28, 2015 — Until two years ago, if you had walked down to the shore of Maquoit Bay at low tide, you would have seen a meadow of eelgrass stretching nearly as far as the eye could see across the exposed seafloor. Here near the head of the bay, the sea grass stretched for two miles to the opposite shore, creating a vast nursery for the shellfish and forage species of Casco Bay, of which Maquoit is a part.

Now there’s only mud.

Green crabs took over the bay in the late fall of 2012 and the spring and summer of 2013, tearing up the eelgrass in their pursuit of prey and devouring almost every clam and mussel from here to Yarmouth. Fueled by record high water temperatures in 2012 and a mild winter in 2013, the green crab population grew so huge that the mudflats of Casco Bay became cratered with their burrowing, and much of the Maquoit and adjacent Middle Bay bottom turned into a lunar landscape.

Eelgrass coverage in Maquoit Bay fell by 83 percent. With nothing rooted to the bottom, the seawater turned far muddier, making life hard on any plants or baby clams that tried to recolonize the bay.

“We were astounded,” says Hilary Neckles of the U.S. Geological Survey’s Patuxent Wildlife Research Center, who linked the destruction to the green crabs. “The ecological ramifications really reverberate throughout the ecosystem, because sea grass is the preferred habitat of so many fish and shellfish species.”

Over the past decade, the Gulf of Maine has been one of the fastest-warming parts of the world’s oceans, allowing warm-water intruders to gain a toehold and earlier invaders such as the green crab to take over. Coupled with declines of the cold-loving species that have dominated the gulf for thousands of years, the ecological effects of even more gradual long-term warming are expected to be serious, even as precise forecasting remains beyond the state of scientific knowledge.

Scientists say the 2012 “ocean heat wave” was an unusual event, and that the 10-year accelerated warming trend is likely part of an oceanographic cycle and unlikely to continue. But the gulf has been consistently warming for more than 30 years, and long-term forecasts project average sea surface temperatures in our region could reach 2012-like levels by mid-century. The events of 2012 and the nearly as warm year that followed likely provide a preview of things to come, of a gulf radically transformed, with major implications for life on the Maine coast.

Genevieve MacDonald, who fishes for lobster out of Stonington, was standing on the dock at Isle au Haut one morning that summer, looked in the water, and couldn’t believe her eyes. There, swimming around the harbor like mackerel, were dozens and dozens of longfin squid, temperate creatures rarely seen in the chill waters of eastern Maine. “If you had a cast net you could have brought in a whole basket full of squid,” she recalls.

Gulf of Maine’s cold-craving species forced to retreat to deeper waters

October 27, 2015 — For 178 years, dams stood across the Penobscot River here, obstructing salmon and other river-run fish from reaching the watershed’s vast spawning grounds, which extend all the way to the Quebec border.

Now, two years after the dam’s removal, the salmon’s proponents fear the fish face a more fearsome threat: a warming sea.

In recent years, the Gulf of Maine has been one of the fastest-warming parts of the world’s oceans, and climate change models project average sea surface temperatures here to increase by another 5.5 degrees Fahrenheit by 2065, a development that could extirpate Atlantic salmon and other cold-loving species, many of which already find Maine at the southern edge of their ranges.

“We’re all for taking down the dams and all the things that are going on to restore habitat, but how much are they looking at the evidence?” asks Gerhard Pohle of the Huntsman Marine Science Center in St. Andrews, New Brunswick, co-author of a study predicting how the changes are likely to affect 33 commercial species over the next 75 years. “Distribution of salmon in the Gulf of Maine would be such that there wouldn’t be many left at all.”

The warming gulf is already presenting challenges to many of its cold-loving denizens. Scientists at the National Marine Fisheries Services, or NMFS, have recorded the steady retreat of a range of commercially or ecologically important fish species away from the Maine coast and into deep water in the southwestern part of the gulf, where bottom water temperatures are cooler.

The retreat, which intensified over the past decade, includes cod, pollock, plaice, and winter and yellowtail flounder. Other native species that once ranged south of Long Island – lobster, sand lance and red hake – have stopped doing so, presumably because the water there is now too warm.

“You can imagine that when you have species at the southern end of their ranges, they will be really sensitive to these changes,” says Michael Fogarty, chief of the Ecosystem Assessment Program at the NMFS Northeast Fisheries Science Center in Woods Hole, Massachusetts. “They will either shift distribution or their survival rates might change.”

MAINE: Big changes are occurring in one of the fastest-warming spots on Earth

October 25, 2015 — Sandwiched on a narrow sandbar between Yarmouth’s harbor and the open Gulf of Maine, the fishermen of Yarmouth Bar have long struggled to keep the sea at bay.

Nineteenth-century storms threatened to sweep the whole place away, leaving Yarmouth proper’s harbor more open to the elements, prompting the province to build a granite cribwork across the quarter-mile bar, behind which the hamlet’s fishing fleet docks. Global warming has brought rising seas, a two-story-high rock wall to fight them and the hamlet’s designation as one of the communities in the province most threatened by climate change.

Now, snaking around the snout of Nova Scotia and into the Gulf of Maine is a new, unseen threat to Yarmouth Bar and hundreds of coastal communities in Maine, eastern New England and the Maritimes: currents fueling the rapid warming of the sea.

The Gulf of Maine – which extends from Cape Cod in Massachusetts to Cape Sable at the southern tip of Nova Scotia, and includes the Bay of Fundy, the offshore fishing banks, and the entire coast of Maine – has been warming rapidly as the deep-water currents that feed it have shifted. Since 2004 the gulf has warmed faster than anyplace else on the planet, except for an area northeast of Japan, and during the “Northwest Atlantic Ocean heat wave” of 2012 average water temperatures hit the highest level in the 150 years that humans have been recording them.

Canadian government hinders scientists from talking about climate change

October 25, 2015 — Half of the Gulf of Maine ecosystem lies in Canada, where much of the water feeding the gulf and affecting its temperature comes from.

Getting information about scientific research relevant to the future of the ecosystem isn’t easy, however, because of the outgoing Canadian government’s controversial policies that have prevented government scientists from speaking freely with journalists, and sometimes from speaking at all.

While researching this six-part series on climate change in the gulf, the Portland Press Herald/Maine Sunday Telegram was repeatedly blocked from speaking to Department of Fisheries and Oceans scientists by communications officers based in Halifax.

Multiple attempts to speak with a researcher based at the St. Andrews Biological Station here about temperature-driven changes in marine species distribution were blocked, even though scientific colleagues both inside and outside the institution said his work was relevant to the questions at hand. “Nobody is willing to talk about this topic at this time,” a DFO spokesman said in a voice-mail message.

Multiple requests to speak to John Loder, director of DFO’s Centre for Ocean Model Development and Application at the Bedford Institute of Oceanography near Halifax, about new sea surface temperature forecasts for the gulf were also denied by department spokespeople, who would only provide written answers to written questions about earlier results from 2013.

NASA commits $6.5M to Gulf of Maine Research Institute for climate change education

October 21, 2015 — The Gulf of Maine Research Institute in Portland is receiving a $6.5 million grant from NASA to create a new educational program focused on science knowledge and problem-solving related to climate change.

The grant will allow the nonprofit organization to upgrade the technical infrastructure at its Sam L. Cohen Center for Interactive Learning in Portland to deliver the new educational content to the 10,000 Maine 5th and 6th graders who visit each year, GMRI announced Tuesday. The organization will also making the educational programing web-accessible to visitors in other science centers and classrooms in Maine and nationwide.

Through customization of the new content from GMRI’s educational program, LabVenture!, the programming will allow students to investigate how climate change is affecting their local region and the rest of the world. The five-year grant, which will begin Nov. 1, will be shared with national science education partners.

Work at GMRI will begin immediately, and new programming content is expected to be available for the 2018-2019 school year.

MAINE: Lobster season proves successful

October 20, 2015 — Maine’s 2015 lobster season is experiencing a boom this year, which according to biologists, stems from factors such as careful fishery management, dropping populations of predators like cod fish, and warming temperatures in the Gulf of Maine.

Experts in the field also point to the fact that lobstering is regulated by a number of federal laws, and that Maine fisheries and governments cooperate with the help of the University of Maine Lobster Institute.

In addition, lobstermen also take an active part in conservation by marking egg-bearing female lobsters, Smithonian.com reported.

Another factor benefitting the industry has been the growth in supply. Exports of the state’s lobsters to China grew from almost nothing five years ago to around 2.7 million pounds last year, with South Korea and Hong Kong showing similarly large increases, according to WISERTrade, which tracks exports.

MAINE: Pembroke company seeks to make Washington County the ‘clam capital of Maine’

October 19, 2015 — It’s a crisp sunny morning in early October in the Washington County town of Pembroke and Tim Sheehan walks briskly across an empty parking lot to greet me. He’d been expecting good news about clam flats in northwestern Cobscook Bay being reopened, but instead of a parking lot full of diggers delivering clams to Gulf of Maine Inc., the seafood business on Route 1 he co-owns with his wife, Amy, there’s just a quiet sunlit absence.

The flats had been closed for almost a week after an historic rainfall on Sept. 30 forced Maine’s Department of Marine Resources to close the entire coast to shellfish harvesting. Even though he knows the closures are a temporary and necessary precaution — until water quality testing determines there’s no longer a risk of runoff pollution contaminating soft shell clams and mussels in the tidal flats — it’s still hard for Sheehan to accept another blank day on his company’s ledgers.

“I’m a dealer, our business depends on clams,” he says.

He’s not alone in that frustration on this bright Tuesday morning. By mid-morning, a dozen or more clammers had sent text messages asking Sheehan if the flats were open yet. Others had pulled up to his seafood warehouse in pickup trucks — some more than once as the sun advanced towards high noon — wondering the same thing.

“Still no word,” Sheehan tells them. Weathered faces nod impassively. They’ve been through this drill before. A full-time clammer, Kittery or Pembroke no difference, is always waiting for something — the tides to change, DMR closures to lift, prices to go up and tiny seed clams to grow to harvestable sizes.

By his own admission, patience doesn’t come easily to Sheehan, who says by nature he’s driven to solve problems. It’s been a hallmark of the wholesale seafood business he and his wife created three years ago, when they realized the scientific specimen business they incorporated in 2002 — whose sales had plummeted with the recession — wasn’t coming back fast enough to keep them in Washington County.

Maine’s Lobster Boom Continues, Feeding Expanding Market

October 17, 2015 — As Maine’s 2015 lobster season heads for the homestretch, the iconic New England fishery continues to show surprising signs of strength while it feeds a growing market.

Mainers appear to be pulling large numbers of lobsters from the waters off their shores, continuing a long winning streak.

Marine experts point to a few likely factors behind the boom: careful fishery management; dropping populations of predators, such as cod fish; and warming temperatures in the Gulf of Maine.

Meanwhile, strong demand for lobster is surfacing in an array of places, from China, whose residents have a growing taste for lobster, to McDonald’s Corp. , which offered a fast-food lobster roll sold in New England this summer. Prices for the clawed crustaceans are up from last year, according to market experts and people connected to Maine’s fishing industry.

In 2014, lobstermen harvested about 124.4 million pounds of lobster from the water fetching an average of $3.70 a pound, according to the state’s Department of Marine Resources. The total catch was shy of an all-time record set in 2013, though the average price rose nearly 28%.
