New England’s 1816 ‘Mackerel Year’ and climate change today

January 19, 2017 — Hundreds of articles have been written about the largest volcanic eruption in recorded history, at Indonesia’s Mt. Tambora just over 200 years ago. But for a small group of New England-based researchers, one more Tambora story needed to be told, one related to its catastrophic effects in the Gulf of Maine that may carry lessons for intertwined human-natural systems facing climate change around the world today.

In the latest issue of Science Advances, first author and research fellow Karen Alexander at the University of Massachusetts Amherst and 11 others including aquatic ecologists, climate scientists and environmental historians recount their many-layered, multidisciplinary investigation into the effects of Tambora on coastal fish and commercial fisheries.

Alexander says, “We approached our study as a forensic examination. We knew that Tambora’s extreme cold had afflicted New England, Europe, China and other places for as long as 17 months. But no one we knew of had investigated coastal ecosystems and fisheries. So, we looked for evidence close to home.”

In work that integrates the social and natural sciences, they used historical fish export data, weather readings,  and town growth chronologies and other sources to discover Tambora’s effects on the Gulf of Maine’s complex human and natural system.

The 1815 eruption caused a long-lasting, extreme climate event in 1816 known as the “year without a summer.” As volcanic winter settled on much of the Northern Hemisphere, crops failed, livestock died and famine swept over many lands. In New England, crop yields may have fallen by 90 percent. The researchers found that 1816 was also called “the mackerel year,” a clue to what they would find regarding fisheries.

Besides Tambora’s climate effects, the authors examined other system-wide influences to explain observed trends. These included historical events such as the War of 1812, human population growth, fish habitat obstruction due to dam building and changes in fishing gear that might have affected fisheries at the time. Employing historical methods in a Complex Adaptive Systems approach allowed them to group and order data at different scales of organization and to identify statistically significant processes that corresponded to known outcomes, Alexander says.

Maine fishermen say there’s plenty of cod. Scientists might give them the chance to prove it.

January 16, 2017 — PORTLAND, Maine — Seeking to end a long-running disagreement about exactly how many cod are left in the Gulf of Maine, federal scientists plan to outfit commercial fishermen with equipment used to establish groundfish quotas.

The fishermen tend to argue that there are more cod than the government realizes; therefore, the number they may legally catch should be higher. Government scientists counter that fishermen’s natural tendency to fish where they are most likely to catch large numbers leads them to overestimate the cod population in the entire Gulf of Maine.

By next year, the Northeast Fisheries Science Center hopes to begin outfitting commercial boats with surveying equipment and paying fishermen to pull in catches that will supplement the regular trawl surveys conducted by government scientists, according to Russell Brown, who heads the center’s population dynamics branch. The gathered data will be fed into the complex process used to set catch quotas.

It’s a collaboration that Brown hopes will give regulators a more detailed picture of the fish population and build trust among fishermen, who in turn see it as an opportunity to show the scientists what’s really going on.

For years, fishermen and scientists have clashed over how to properly estimate fish populations and set the catch quotas that rule the livelihoods of Maine fishermen. Fishermen suggest that scientists are missing fish and setting the quotas too low, while scientists say fishermen are missing the big picture. But both groups believe collaboration would be a positive step toward better protecting Maine’s fishing industry and environment, even as ocean waters warm.

“It’s really perplexing that you’ve got a set of federal scientists who are sampling the ocean methodically and coming up with a very different picture than the fishermen about what’s going on out in the Gulf of Maine,” Jonathan Labaree of the Gulf of Maine Research Institute said.

MASSACHUSETTS: Gloucester fisherman represents state in shrimp study

January 11, 2017 — Joe Jurek is no stranger to the Gulf of Maine northern shrimp fishery, having incorporated shrimping into his annual fishing calendar even after moving to Gloucester about a decade ago to groundfish.

“When sectors started in 2009, we would catch our groundfish quota as quickly as we could and then go fish the other fisheries, including the northern shrimp fishery,” Jurek said Tuesday. “I shrimped long before that, though. You could say it’s kind of my background.”

Jurek, owner and skipper of the 42-foot F/V Mystique Lady, will be the lone Massachusetts representative in the upcoming Gulf of Maine winter shrimp sampling program that will produce the only legal shrimping in 2017 in the Gulf of Maine.

The Mystique Lady is one of 10 trawlers participating in the sampling program, along with eight from Maine and one from New Hampshire captained by Mike Anderson of Rye. Jurek hopes to begin shrimping as soon as this weekend.

“I’m trying to get rolling so I can start Sunday,” Jurek said. “I’m really excited about catching some shrimp and about this program.”

He already has reached out to local lobstermen, providing a map of the area he intends to trawl and asking lobstermen to alert him to the presence of any gear that might be set or soaking in the area.

“If you have gear in the highlighted areas please touch base with me so we can work together,” Jurek wrote on his Facebook page. “And I will make sure I don’t tow thru any gear.”

A high-tech battle for the future of the fishing industry

January 3, 2017 — OFF THE COAST OF SCITUATE, Mass. — The high-tech battle for the future of the Massachusetts fishing industry is being waged aboard a western-rigged stern trawler named the Miss Emily.

Onboard the commercial groundfish vessel, in addition to the satellite positioning system and other sophisticated tools that have become standard in the industry, are at least five computer monitors and a $14,000 fish-measuring board that has halved the time it takes to gauge the catch.

State officials say it’s money well spent.

Federal catch limits — caps on how many fish each boat can catch — have devastated the state’s most iconic commercial sector, fishermen say. In response to an outcry from the struggling local groundfishing industry, environmental officials are now using the Miss Emily to try to come up with a new — and, they say, more accurate — estimate of codfish in the Gulf of Maine.

Under a survey launched last April, local fishermen hope new technology and an aggressive timetable will yield what they have concluded based on their own anecdotal evidence: There are more fish in the sea.

“That’ll give the federal scientists something to think about,” says David Pierce, director of the state’s Division of Marine Fisheries. “It’s going to be eye-opening, I suspect. It’s going to force them to do some soul-searching.”

National Oceanic Atmospheric Administration estimates put the Gulf of Maine groundfish stock at historically low levels, dictating a corresponding reduction in catch limits. Between 1982 and 2013, the number of metric tons of cod landed aboard commercial vessels plunged from more than 13,000 to 951, according to federal estimates. That, predictably, has drastically undercut the industry.

“The fleet has been decreasing in size, and we’re seeing less effort due to these catch limits,” says Bill Hoffman, a senior biologist with the state who oversees the survey. “Guys have gotten out.”

The 55-foot Miss Emily, skippered out of Scituate by captain Kevin Norton, has been equipped to approximate a smaller version of the Henry B. Bigelow, a 209-foot floating research vessel operated by NOAA, that is used to count fish for the federal government. Using a small portion of $21 million in federal fisheries disaster relief, the state launched a series of random “tows” to counter what some think is the less accurate federal vessel.

MAINE: 2017 Maine Northern Shrimp Cooperative Winter Sampling Program Participants Announced

December 29, 2016 — The following was released by the Maine Department of Marine Resources:

Maine participants in the cooperative winter sampling program for Northern Shrimp in the Gulf of Maine have been announced. The program, coordinated by the Maine Department of Marine Resources, the New Hampshire Fish and Game Department, and the Massachusetts Division of Marine Fisheries, is designed to provide biological data on the shrimp fishery which is closed for the fourth year in a row.

The Maine fishermen have been chosen from over 60 applicants, based on a random drawing of those fully qualified in each region. Qualifications include a demonstrated shrimp fishing history, and successfully passing a Marine Patrol review of marine resource violations.

Preference was given to trawlers willing to participate in a test of a compound grate for harvesting. Compound grates are devices used by trawlers to reduce the catch of small shrimp.

Maine harvesters chosen include trawlers Vincent Balzano, Joseph Leask, and Rob Tetrault from western Maine, Troy Benner, David Osier and Arthur Poland Jr. from mid-coast Maine, and Randy Cushman and Glenn Libby from eastern Maine.

Shrimp trappers include Chad Gamage, Daryl Chadwick, George Gilbert and Robert Tracy from mid-coast Maine, and Thomas Riedel from eastern Maine.

In response to the depleted condition of the northern shrimp resource, the Atlantic States Marine Fisheries Commission’s Northern Shrimp Section extended the moratorium on commercial fishing for the 2017 fishing season. The Section also approved a 53 metric ton research set aside (RSA) which will be used by the cooperative sampling program to provide managers with much-needed biological data. Biological data gathered will include size composition and egg hatch timing.

In total, the sampling program will include the participation of 10 trawlers (8 Maine trawlers, 1 Massachusetts trawler, and 1 New Hampshire trawler) and 5 Maine trappers, fishing for 8 weeks from mid‐January to mid‐March, 2017.

The trawlers will be allowed a maximum trip limit of 1,200 pounds, with 1 trip per week, while the trappers will have a maximum possession limit of 500 pounds per week, with a 40 trap limit per vessel. All participants will provide shrimp samples to the Maine DMR weekly.

Information on the sampling program can be found at http://www.maine.gov/dmr/science-research/species/shrimp/winter2017.html.

Mercury Levels in Gulf of Maine Tuna on the Decline

December 29, 2016 — There’s some good news for sushi lovers. A new report finds that over an 8-year period, mercury levels in Gulf of Maine tuna declined 2 percent a year — a decline that parallels reductions in mercury pollution from Midwest coal-fired power plants.

Two years ago, Dr. Nicholas Fisher, a professor of marine sciences at Stony Brook University in New York, had a bit of luck — he found out that a colleague had established a collection of 1,300 western Atlantic bluefin taken from the Gulf of Maine between 2004 and 2012.

“They were frozen, wasn’t the entire fish, just about a pound from each fish or so. And then my colleagues and I in New York dissected out muscle tissue from each sample and analyzed it to determine the mercury content of each fish,” he says.

And as they created a timeline for mercury content for each year, taking into account the age and size of each fish sampled, a clear picture emerged.

“There was a fairly steady decline for all ages of fish, and the decline rate was approximately 2 percent per year, which doesn’t sound all that dramatic, but over 10 years it’s about 20 percent. Over two decades its about 40 percent,” Fisher says.

Most mercury pollution in this region originates from coal-fired plants in the Midwest, drifting east on the prevailing winds to drop on the coast and coastal waters. In response to regulatory and industry efforts, and to market forces, those emissions happen to have been declining by about 2 percent a year.

MASSACHUSETTS: Fishing in 2016: The year didn’t go swimmingly for industry

December 28, 2016 — The past year in the commercial fishing industry and along the city’s waterfront has been one of battles, as the city’s legendary fishing industry has fought to remain viable in the midst of regulatory, economic and environmental pressures.

Groundfishermen spent much of the year dueling with NOAA Fisheries over who should pay for mandated at-sea monitoring. And fishing advocates, led by the Gloucester-based Northeast Seafood Coalition, continued their crusade questioning the quality of the science NOAA uses in its stock assessments.

Lobstermen, NOAA scientists and elected representatives such as U.S. Rep. Seth Moulton, took on Sweden over the Scandinavian country’s attempt to convince the European Union to list American lobsters as an invasive species and ban their importation.

Those skirmishes have taken place against the backdrop of the most disturbing and over-arching single piece of information to emerge in 2016 — the Gulf of Maine, already effectively shuttered to cod fishing and shrimping, is warming faster than 99.9 percent of the rest of the planet’s oceans and doing so at an accelerated rate.

Coral plan threatens fishing grounds

December 21st, 2016 — Area lobstermen could lose valuable fishing grounds if a federal proposal to close four areas of Gulf of Maine waters comes to fruition.

The New England Fishery Management Council (NEFMC) has drafted a plan that would close a span of 161 square miles offshore to commercial fishing in an effort to conserve deep-sea coral there.

Two of those areas, Mount Desert Rock in Lobster Management Zone B and Outer Schoodic Ridge in Lobster Management Zone A, are preferred fishing grounds for local fishermen when lobster head further offshore in the winter. The other proposed offshore closure areas lie in Jordan Basin and Lindenkohl Knoll to the south.

The Mount Desert Rock and Outer Schoodic Ridge areas are prime for lobster fishing, while Jordan Basin and Lindenkohl Knoll see a mix of groundfish, monkfish, pollock and lobster.

The NEFMC is working with the Mid-Atlantic Fishery Management Council and the South Atlantic Fishery Management Council to preserve deep-sea corals from the Canadian border to Virginia.

According to the NEFMC, the fragile and slow-growing corals are vulnerable to damage by fishing gear.

“While the extent of deep-sea coral habitat degradation has not been quantified in most areas, bottom tending fishing gear has been known to cause significant disturbance in many locations and is considered to be the major threat to deep-sea corals in areas where such fishing occurs,” read a recent NEFMC memorandum.

Fishermen must hold federal permits to fish in offshore waters. According to NEFMC data, 31 percent of Zone B fishermen hold federal permits.

Fisheries council sets up 2017 priorities

December 20th, 2016 — The New England Fishery Management Council has set its management priorities for 2017, including potential revisions to the management of Atlantic halibut and an examination of the implications of groundfish catches in non-groundfish fisheries.

The list of priorities, which largely charts the council’s expected — perhaps more accurately, hopeful — course in the upcoming year, was approved by the full council after about three hours of discussion at its November meeting.

The prioritization of issues, according to NEFMC Executive Director Tom Nies, is a valuable tool for providing the council with the structure to address pressing issues while also retaining the flexibility to delve into other issues as they present themselves to the council.

“The process is very helpful in focusing the efforts of the council on major tasks and still give it the flexibility through the rest of the year to change course as we have to,” Nies said.

The list of priorities would see the council:

Consider of possible regulatory changes to the northern Gulf of Maine scallop management area;

Improve the Gulf of Maine cod and haddock recreational management process;

Initiate actions to resume landings of the rebuilt barndoor skate stock;

Coordinate long-term wind power issues with other regulatory agencies, and;

Conduct a comprehensive review of council operations.

New England Fishery Managment Council Approves 2017 Management Priorities

December 16, 2016 — The following was released by the New England Fishery Managment Council:

The New England Fishery Management Council recently approved its 2017 management priorities, which will guide the Council’s committees and working groups in the year ahead. The Council annually takes this step for two reasons: to focus its time on mutually agreed-upon issues of importance; and to give the public a snapshot of what to expect in the foreseeable future.

“Our priority-setting exercise helps us determine how to best allocate available resources,” said Council Executive Director Tom Nies. “We always have more proposals on the table than we’re able to handle each year, so by collectively deciding upfront which actions rank the highest, we’re able to work much more efficiently on the Council’s most pressing issues without getting sidetracked.”

Setting annual catch limits and other fishery specifications – a requirement under the Magnuson-Stevens Fishery Conservation and Management Act – remains the Council’s highest cross-cutting priority.

But for 2017, the Council also supported many high-priority items that fishermen and other stakeholders said were especially important. Here are a few of the highlights that were approved during the Council’s mid-November meeting in Newport, Rhode Island:

  • Sea scallops: Consider regulatory changes to the Northern Gulf of Maine Management Area;
  • Groundfish: Revise Atlantic halibut management measures;
  • Groundfish: Review groundfish catches in “other” non-groundfish fisheries and assess implications;
  • Recreational fishing: Improve Gulf of Maine cod and haddock recreational management process;
  • Barndoor skates: Initiate action to allow landings of this rebuilt species;
  • Habitat: Coordinate wind power issues with other agencies over the long term, not just 2017; and
  • Council: Conduct a programmatic review of Council operations.
  • Atlantic herring – Continue work on Amendment 8 to address localized depletion and user conflicts in the fishery and develop a new acceptable biological catch control rule using a Management Strategy Evaluation (MSE) process;
  • Habitat – Complete the Omnibus Deep-Sea Coral Amendment and a separate framework adjustment to address surf clam fishery access to pending Habitat Management Areas;
  • Whiting – Move forward with Amendment 22 to consider limited access for the Small-Mesh Multispecies Complex and consider changes to possession limits;
  • Skates – Prepare an amendment to consider limited access for both the skate bait and skate wing fisheries with provisions that may consider catch share alternatives; and
  • Ecosystem-Based Fishery Management – Continue work on the development of operating models and a draft example Georges Bank Fishery Ecosystem Plan and develop a MSE process to engage fishermen and other stakeholders while conducting testing and validation.
