Education key to electronic reporting, monitoring systems

February 1, 2018 — NEW BEDFORD, Mass. — In a perfect world, Steve Kennelly sees the New England Fishery transitioning to electronic reporting within the next year.

“There’s no reason why that group can’t be formed pretty soon,” the director of IC Independent Consulting said.

The next step would be implementing electronic monitoring within 3 to 4 years.

“It’s silly to talk anywhere beyond five years out” because of how fast technology continues to evolve, Kennelly said.

The New England Fishery Management Council, which concluded two days of meetings on Wednesday in Portsmouth, New Hampshire, resides in an imperfect world, though.

Some of the research presented by Kennelly and Mark Hager, of the Gulf of Maine Research Institute, was based on establishing electronic reporting and monitoring from scratch. That wouldn’t entirely be the case as some fisheries and vessels are using or testing the electronic systems.

“A KISS approach – keep it simple – didn’t happen,” Kennelly said.

In gathering their research, Kennelly and Hager interviewed 79 fishermen during the last two months of 2017. Of the 79 people they spoke with, 21 were fishermen, 30 were staff from the National Marine Fishery Service and 10 were representatives from fishermen’s associations.

The discussions provided positive and negative notions about electronic systems, which Kennelly and Hager discussed in depth, however, they also revealed a lack of understanding, in their opinion.

Kennelly said some interviews were prefaced by 15 to 20 minutes of explaining the difference between electronic reporting and monitoring as well as what each could provide.

“It’s not because people are being misinformed, they’re just not as aware,” Kennelly said.

Maine disputes study that predicts sharp decline in Gulf of Maine lobsters

The Department of Marine Resources won’t be using researchers’ model to make management decisions, saying that forecasting fishery populations 30 years out is extremely difficult.

January 29, 2018 — The state agency that oversees Maine’s marine fisheries is questioning the reliability of a new study that predicts a sharp decline in Gulf of Maine lobsters over the next 30 years.

The Gulf of Maine Research Institute, the University of Maine and the National Oceanic and Atmospheric Administration built a computer model that predicts the population will fall 40 to 62 percent by 2030.

But Patrick Keliher, commissioner of the Department of Marine Resources, won’t be using the model to help him decide how to manage the state’s most valuable fishery, which pumped $533.1 million into the state economy in 2016.

“(He) does not have confidence in a model that simulates what might happen decades in the future,” spokesman Jeff Nichols said. “This is a wild resource, making predictions extremely challenging.”

Thirty years ago, when landings were less than 20 million pounds, no one could have predicted that the Maine lobster fleet would be landing more than 130 million pounds a year in 2016, Nichols said.

“The commissioner and his science staff don’t question the science, but rather see this as an unreliable tool on which to base management decisions,” he said.

The department isn’t alone in having doubts about the study. Maine lobster dealers voiced skepticism, too, recalling previous erroneous lobster forecasts by some of the same scientific organizations.

Conservation Practices Help Lobsters Weather Climate Change

January 29, 2018 — It’s no secret that the lobster fishery in southern New England is in trouble. The population has declined by almost eighty percent in the past few decades. In contrast, lobsters in the Gulf of Maine have exploded and the fishery has seen record landings. So, what gives?

Rising water temperatures are a big part of the story. Baby lobsters have a set-point: 61.5°F. Go much above that, and first-year lobsters start dying off. That’s what has been happening during recent summers in places like Buzzards Bay and Narragansett Bay. Meanwhile, in the Gulf of Maine, which is one of the most rapidly warming ocean areas anywhere in the world, the increase in temperatures has put lobsters into their sweet spot.

But that’s not where the story ends. A new study used a computer model to tease apart the influence of environmental changes and conservation practices, which differ significantly between Maine and southern New England. For generations, Maine lobstermen have been throwing back fertile females (after cutting a notch out of their tails so that they can be recognized even when they’re not carrying eggs) and the biggest lobsters. Those practices didn’t hit southern New England until a decade ago.

The conclusion of the new analysis is a bitter pill for southern New England lobstermen, according to Andrew Pershing, chief scientific officer and head of the Ecosystem Modeling Lab at Gulf of Maine Research Institute.

New report says future of Maine lobster industry could be worse

January 29, 2018 — ELLSWORTH, Maine — Warming ocean waters will have a big impact on Maine’s $547 million lobster industry in coming years, but the future would look a lot bleaker if not for the conservation efforts of the state’s thousands of lobster fishermen.

According to a study led by scientists at the Gulf of Maine Research Institute, the University of Maine and NOAA Fisheries, conservation practices long advocated by Maine lobstermen are helping make the lobster fishery more resilient to climate change.

For generations, lobstermen in Maine have returned large lobsters and egg-bearing female lobsters to the water rather than keeping them. Lobstermen first marked the tails of the egg bearers with a distinctive “V-notch” to give them further protection.

According to the scientists, these conservation practices, developed by custom and now mandated by state law, distinguish the fishery in the Gulf of Maine, where Maine harvesters trap some 83 percent of all lobster landings, from southern New England, where fishermen historically refused to take the same steps to preserve large, reproductive lobsters.

Funded by the National Science Foundation and published this week in the Proceedings of the National Academy of Sciences, the study shows how warming waters and contrasting conservation practices have contributed to significantly different results in the two fisheries.

Over the past decade (at least until this past year), Maine lobster landings have climbed steadily, setting new records nearly every year. During the same time period, the southern New England lobster population, and lobster fishery, has collapsed.

According to figures compiled by regulators, the commercial lobster landings in Connecticut fell from more than 2.5 million pounds in 1995 to about 200,000 pounds in 2015. In Rhode Island, the catch fell from more than 5 million pounds in 1995 to less than 2.4 million pounds in 2015. In New York, the commercial lobster industry has virtually disappeared.

Led by Arnault Le Bris of the Gulf of Maine Research Institute, the scientists used advanced computer models to simulate the ecosystem under varying conditions. The results show that temperature change was the primary contributor to population changes, but conservation efforts made significant differences in how the lobster population responded.

Study: Warming Gulf of Maine endangering lobster stock

January 24, 2018 — Is the lobster boom on the decline in the Gulf of Maine because of warming waters? A newly released study by a Maine-based marine research group suggests that is the case.

The study, released Monday by the Gulf of Maine Research Institute, touched on many of the same climate issues that have left researchers and lobster stakeholders anxious about the future.

“In the Gulf of Maine, the lobster fishery is vulnerable to future temperature increases,” GMRI said in the statement released with the study. “The researchers’ population projections suggest that lobster productivity will decrease as temperatures continue to warm, but continued conservation efforts can mitigate the impacts of future warming.”

The study, compiled with the University of Maine and NOAA Fisheries, said the anticipated decline highlights the need for vigilant conservation within the Gulf of Maine lobster fishery, especially since scientists say the gulf’s waters are warming faster than 99 percent of the rest of the world’s oceans.

Researchers said they expect the lobster population to decline from recent highs — GMRI pegs the peak year at 2010, when it estimated the Gulf of Maine lobster stock contained 518 million lobsters — to levels more in keeping with traditional lobstering years.

It estimates the population could shrink to about 261 million lobsters in 2050.

“The 30-year outlook for the Gulf of Maine fishery looks positive if conservation practices continue,” GMRI said. “In their 30-year projection, the researchers anticipate average populations similar to those in the early 2000s.”

Beth Casoni, executive director of the Massachusetts Lobstermen’s Association, said lobster stock assessments in the Gulf of Maine have shown the annual settlement of young lobsters — when they transition from floating in open waters as plankton to settling on the bottom to begin the seven- to eight-year stretch it requires to mature — has declined from previous assessments.

Research Concludes Maine Conservation Technique Helped Drive Lobster Population Boom

January 24, 2018 — Lobster conservation techniques pioneered by Maine fishermen helped drive a population boom that’s led to record landings this century. That’s the conclusion of new, peer-reviewed research published today.

The paper also finds that lobstermen in southern New England could have used the same techniques to prevent or at least slow the collapse of their fisheries — even in the face of climate change — but they didn’t.

Cape Elizabeth lobsterman Curt Brown has been hauling traps since he was a kid. He says he quickly learned that when he pulled up a female lobster, covered in eggs, he was looking at the fishery’s future.

Maine lobstermen throw back lobsters like these, which produce eggs at a high rate, but other lobstermen do not

“You get used to seeing lobsters and then you see a lobster with eggs and it’s whole new animal,” he says. The underside of the tail is just covered with eggs.”

Since 1917, Maine lobstermen like Brown have used a technique known as “V-notching”: when they found an egg-bearing female in their traps, they would clip a “V” into the end of its tail, and throw it back. The next time it turns up in someone’s trap, even if it’s not showing eggs, the harvester knows it’s a fertile female, and throws it back. Later, the lobstermen also pushed the Legislature to impose limits on the size of the lobster they can keep — because the biggest ones produce the most eggs.

“I use my measure right here, right on the measure, at the end of the measure, is a little tool in the shape of a ‘V,'” Brown says. “So you just grab the lobster underside of the tail just like that and it cuts a V-notch right in the tail. Quick, painless, throw her back in and let her do more of her job.”

And those fertile females have been doing that job very well in Maine. Since the 1980s, lobster abundance here has grown by more than 500 percent, with landings shooting up from fewer than 20 million pounds in 1985, to more than 120 million pounds in 2015 with a value of more than a half billion dollars.

Gulf of Maine lobster population past its peak, study says, and a big drop is due

January 23, 2018 — The Gulf of Maine lobster population will shrink 40 to 62 percent over the next 30 years because of rising ocean temperatures, according to a study published Monday.

As the water temperature rises – the northwest Atlantic ocean is warming at three times the global average rate – the number of lobster eggs that survive their first year of life will decrease, and the number of small-bodied lobster predators that eat those that remain will increase. Those effects will cause the lobster population to fall through 2050, according to a study by researchers at the Gulf of Maine Research Institute, the University of Maine and the National Ocean and Atmospheric Administration.

Looking ahead 30 years, the researchers predict a lobster population “rewind” to the harvests documented in the early 2000s. In 2002, 6,800 license holders landed 63 million pounds of lobster valued at $210.9 million. By comparison, 5,660 license holders harvested 131 million pounds valued at $533.1 million in 2016.

“In our model, the Gulf of Maine started to cross over the optimal water temperature for lobster sometime in 2010, and the lobster population peaked three or four years ago,” said Andrew Pershing, GMRI’s chief scientific officer and one of the authors of the study. “We’ve seen this huge increase in landings, a huge economic boom, but we are coming off of that peak now, returning to a more traditional fishery.”

Industry leaders have been girding themselves for a decline in landings ever since the recent boom began. While not everybody believes the decline will happen that fast or fall so much, most lobstermen admit the impact that warming water has had on their fishery, said Dave Cousens, the president of the Maine Lobstermen’s Association. It drove up landings by pushing lobsters into the Gulf of Maine, and over time it will drive lobsters out to colder offshore waters or the Canadian Maritimes, he said.

The lobster catch has crashed in southern New England, but not in Maine. Here’s why.

January 23, 2018 — Scientists who study the warming of the ocean say in a new study that conservation practices have allowed northern New England’s lobster industry to thrive in the face of environmental changes.

The lobster fishery is the backbone of Maine’s economy, and business has been booming in recent years. Southern New England fishermen’s lobster catch, meanwhile, has plummeted. Ocean temperatures have risen in both areas, to levels that scientists have said is favorable for lobsters off northern New England and Canada but inhospitable for them in southern New England.

Scientists led by researchers at the Gulf of Maine Research Institute in Portland say differences in conservation practices have contributed to record hauls off Maine and population collapse just a few hundred miles south. Their findings were published on Monday in the Proceedings of the National Academy of Sciences.

A key difference is that Maine lobstermen worked together decades ago to create a strategy to protect older, larger lobsters and egg-carrying females, said Andy Pershing, a scientist with Gulf of Maine Research Institute and one of the study authors.

Maine lobstermen return big lobsters to the sea, and mark a “v notch” on the tail of an egg-carrying lobster before throwing it back. The notching technique, used in Maine for about a century, provides a sign to other fishermen to leave the fertile lobsters alone. Fishermen in other states use the notch, too, but some got on board only recently; Connecticut established its program in the mid-2000s.

New study: Industry conservation ethic proves critical to Gulf of Maine lobster fishery

January 22, 2018 — A new study, led by scientists at the Gulf of Maine Research Institute and colleagues at the University of Maine and NOAA, demonstrates how conservation practices championed by Maine lobstermen help make the lobster fishery resilient to climate change.

For generations, lobstermen in Maine have returned large lobsters to the sea and have designed a special way of marking egg-bearing lobsters to give them further protection. This conservation culture distinguishes the Gulf of Maine fishery from southern New England, where fishermen have not historically taken the same steps to preserve large, reproductive lobsters.

The study, funded by the National Science Foundation and published in Proceedings of the National Academy of Sciences (PNAS), shows how warming waters and contrasting conservation practices contributed to simultaneous record landings in the Gulf of Maine fishery and  collapse in southern New England.

Led by Dr. Arnault Le Bris, the research team used advanced computer models to simulate the ecosystem under varying conditions, allowing them to understand the relative impacts of warming waters, conservation efforts, and other variables. Their results show that, while temperature change was the primary contributor to population changes, conservation efforts made a key difference in population resiliency.

Impacts of warming

Over 30 years (1984-2014), ocean temperatures increased rapidly in both regions. Warming in both regions shifted optimal summer ocean temperatures northeast, causing the southern New England  population to decline and the Gulf of Maine population boom. The researchers estimate that, during this 30-year period, the Gulf of Maine population increased by 515%, while the southern New England population declined by 78%. Challenges associated with warmer temperatures include decreased survival of larval lobsters, increased incidence of shell disease, and increased predation.
