Lobster stock assessment shows decline, lobstermen say different factors at play

November 12, 2025 — The American Lobster Benchmark Stock Assessment and Peer Review Report, which assesses the stability of the lobster stock and informs how to manage it, was released Oct. 30, finding that the Gulf of Maine and Georges Bank stocks have declined 34% since peak levels in 2018. The report found that the stock is not depleted but attributed the decrease to overfishing, a finding that some local lobstermen have differing perspectives on.

In contrast, the report, which is commissioned by the Atlantic States Marine Fisheries Commission, found that in waters farther south, the Southern New England stock has been significantly depleted but not overfished, “with record low abundances for all life stages in recent years.”

For the Gulf of Maine/Georges Bank stocks, “the average abundance from 2021-2023 was 202 million lobsters, which remains above the abundance limit reference point but below the fishery/industry target, indicating the stock’s ability to replenish itself is not jeopardized, but economic conditions for the lobster fishery may be degrading,” reads an Oct. 30 press release from ASMFC. “The average exploitation from 2021-2023 was just above the exploitation threshold, indicating overfishing is occurring.”

For context, 82% of lobster landings in the U.S. come from the Gulf of Maine fishery, where small vessels making day trips in nearshore waters make up the bulk of those catches. At just 5% of U.S. landings are larger vessels making multi-day trips offshore with the Georges Bank fishery.

Lobstermen push back on ASMFC overfishing claim

November 10, 2025 — The Atlantic States Marine Fisheries Commission (ASMFC) announced last week that while the Gulf of Maine and Georges Bank (GOM/ GBK) lobster stock remains above its abundance threshold, overfishing is occurring, a finding that has sparked concern and disagreement from industry groups who say the assessment overstates fishing’s role in the stock’s recent decline.

The 2025 American Lobster Benchmark Stock Assessment was released on Oct. 20 and stated that the GOM and GBK stock has declined by 34 percent since its peak in 2018, though it is “not depleted” and continues to support a robust fishery. In contrast, the Southern New England stock remains “significantly depleted” but is not experiencing overfishing, with abundance at record lows across all life stages.

“The Benchmark Stock Assessment is a considerable advancement in our understanding U.S. American lobster resource. It was fully endorsed by an external panel of fishery scientists as the best scientific information available to manage the lobster resource,” stated Board Chair Renee Zobel from New Hampshire. “On behalf of the American Lobster Board, I commend the members of the Technical Committee and Stock Assessment Subcommittee for their outstanding work on the 2025 Benchmark Stock Assessment Report. This assessment reflects the commitment of the Committee and Peer Review Panel to providing the Board with the highest-caliber science to inform management decisions and improve our understanding of the complex and changing relationship between the environment and lobster resource.”

Stock assessment for US lobster shows population shifts, minor overfishing

October 31, 2025 — A recent stock assessment by the Atlantic States Marine Fisheries Commission (ASMFC) indicates lobster stock on the East Coast of the U.S. is depleted to record low abundance in Southern New England (SNE), and overfishing of the stock is occurring in the Gulf of Maine and Georges Bank (GOM/GBK).

The lobster benchmark assessment found the stock in GOM/GBK – which accounts for the vast majority of lobster landings in the U.S. – has declined 34 percent since peak levels in 2018. According to the ASMFC, the GOM region in particular has accounted for an average of 82 percent of annual landings since 1982, while the GBK fishery accounts for 5 percent.

Catch limits for scallops on Georges Bank reduced due to increase in predator population

October 28, 2025 — One of Nova Scotia’s most lucrative seafood species is being attacked by natural predators on one of the most famous fishing grounds.

What remains to be seen is whether it’s a short-term occurrence or a sign of things to come.

A recently published stock assessment by Fisheries and Oceans Canada for sea scallops in Scallop Fishing Area (SFA) 27A on Georges Bank notes major changes in the amount of biomass and natural mortality rates. The changes were dramatic enough that DFO reduced the total allowable catch last December.

Fully recruited biomass decreased to 13,570 tonnes in 2024 from 31,095 tonnes in 2023 after fluctuating “within the healthy zone since the 2000s,” the science advisory report said. Fully recruited refers to commercial-size scallops.

Recruit biomass — the total mass of new scallops in the population — dropped by 72 per cent from 2023 to 2024.

The report said the “significant interannual changes” in stock condition for the SFA are likely driven by environmental variability.

“Research vessel survey data from Canada and the United States suggest that predator abundance, notably sea stars and crabs, has increased within the areas of known scallop distribution. Aggregations of predators in areas of high scallop density contribute to increases in natural mortality.”

MASSACHUSETTS: Scallopers push to open northern edge of Georges Bank

July 31, 2025 — Coastal lawmakers and scallopers railed Wednesday against a decision fishing regulators made last year to keep closed the northern edge of Georges Bank, a thriving scallop ground that has been shuttered to commercial fishing since 1994.

“It’s singularly my most frustrating experience, as someone who thinks of the environment every day, but also worries about the economy minute to minute in my own district. It’s stunning to me how long — decades — this has been closed,” said Sen. Mark Montigny of New Bedford.

Montigny chaired a Senate Committee on Post Audit and Oversight hearing on Wednesday which explored the state of commercial sea scallop fisheries and regulations impacting the industry.

New Bedford is the largest port in the United States for sea scallop landings and revenue. Other ports in Massachusetts are important for smaller scallop vessels, including Gloucester, Provincetown, Barnstable and Chatham.

Last year, the New England Fishery Management Council voted against reopening the fishing grounds on the northern edge of George’s Bank, a shallow underwater plateau between Cape Cod and Nova Scotia that is rich in biodiversity and a known spawning ground for Atlantic cod and habitat for scallops. The Light reported that Mayor Jon Mitchell was among those asking the council to reconsider opening it, citing headwinds for the region’s top fishery, including falling prices and fewer days at sea for fishermen.

The council voted not to continue discussions on reopening the area, as they said the high density of scallops there helps spawn other nearby scalloping grounds.

Fishers want ‘incredibly important’ Georges Bank protected against offshore wind development

September 17, 2024 — As Nova Scotia rushes to establish an offshore wind industry, some fishers are calling for explicit protection for the rich fishing ground on Georges Bank.

The cabinet minister in charge of developing renewable energy projects says he will keep turbines off the bank, but not by changing a piece of legislation that is now moving through Province House.

Ian McIsaac, president of the Seafood Producers Association of Nova Scotia, brought his concerns to a legislature committee Monday as it reviews a new bill that, if passed into law, would enable offshore wind development.

McIsaac said Bill 471 doesn’t update the Georges Bank moratorium that’s been in place against offshore petroleum development since the 1980s.

“We feel this is a technical error,” he said.

“In the past, whenever the moratorium has come up for consideration, it has been subject to intense study of the environmental and socio-economic impacts of change, to determine if, in fact, such changes are appropriate.”

US lobster fishery faces delay in gauge-size increase; Canadian harvesters call for government to do more to combat illegal fishing

August 13, 2024 — The Atlantic States Marine Fisheries Commission (ASMFC) Lobster Board has initiated the process to delay a gauge size increase for the U.S. lobster fishery until 1 July 2025.

The ASMFC first delayed an increase in the lobster gauge size in October 2023, after lobster trawl surveys indicated a decline in the population of sub-legal lobsters. The gauge size increase was first initiated in 2017 as a proactive measure to improve the resiliency of the lobster stock in the Gulf of Maine and Georges Bank, but that process was paused to focus on issues related to entanglement of North Atlantic right whales.

NEFMC Seeks Contractor to Conduct Prototype MSE for Ecosystem-Based Fishery Management

May 18, 2022 — The following was released by the New England Fishery Management Council:

The New England Fishery Management Council seeks the services of an independent contractor to develop and conduct a prototype management strategy evaluation (MSE) for Georges Bank. The protype MSE will be based on the ecosystem-based fishery management (EBFM) strategy in the Council’s example Fishery Ecosystem Plan (eFEP).

This is a short-term, temporary contractor role, commencing on or about August 1, 2022 and ending in January 2023. The intended completion date will depend on the scope and complexity of the work and the MSE proposed by the applicant. The deadline for submitting letters of interest and supporting materials is Wednesday, June 30, 2022 at 5:00 p.m.

The purpose of the prototype MSE is to:

Showcase a simplified prototype MSE framework and demonstrate how MSE will be used to evaluate EBFM management strategies for a Georges Bank Ecosystem Production Unit, using what we learn to communicate with the public about MSE for EBFM;
Act as an educational dry run from both a development and an operational perspective;
Provide an opportunity for the Council and its EBFM Committee to gain experience with the MSE process;
Identify and work through the types of decisions to be made during an MSE; and
Identify data sources and develop the models and analyses that will support a full EBFM MSE with broader stakeholder participation in the next phase of the Council’s EBFM development strategy.

The prototype MSE results, while intended to be realistic, are not meant to be actionable in a fishery ecosystem plan. Rather, the results will be used as the basis for a full MSE, which is the next step.

Working with Council staff, the Council’s EBFM Plan Development Team, and a limited number of appointed stakeholders, the contractor will:

Develop new or expand existing operating models that represent the productivity of and trophic relationships among managed stocks on Georges Bank;
Identify and apply existing estimation (assessment) models;
Identify management objectives and candidate management procedures (e.g., harvest control rules) based on the Council’s ecosystem cap and ceilings and floors approach for stock complexes; and
Provide concise and approachable summaries that show the trade-offs between alternative management procedures to meet multiple objectives.

Complete details about the project background, prototype MSE objectives, statement of work, expected responsibilities and deliverables, desired experience and demonstrated skills, and application submission information can be found in the request for proposals.

EBFM Outreach Ramping Up: Watch the Five-Minute Video, View the Infographics, Check out the Brochures

May 3, 2022 — The following was released by the New England Fishery Management Council:

The New England Fishery Management Council is preparing to conduct public information workshops in six different fishing ports to help fishermen and other stakeholders better understand what ecosystem-based fishery management (EBFM) is all about. These workshops, which are under development, are expected to be held later this summer or early fall.

In the meantime, the Council is encouraging people to become familiar with the extensive array of outreach materials posted on the EBFM public information outreach webpage. Here are some highlights.

The Council has been exploring ecosystem-based fishery management for several years now. The upcoming public information workshops are intended to help inform fishermen and other stakeholders about EBFM and its potential application to a Georges Bank Ecosystem Production Unit. The Council has been referring to this approach as an example Fishery Ecosystem Plan for Georges Bank, which often is simply called the eFEP.

During its April 2022 meeting, the Council received a progress report on the latest EBFM outreach efforts and workshop planning. Another update is planned for the June 2022 meeting. The Council also received an update on work being done to develop a simplified, prototype management strategy evaluation (pMSE) for EBFM. This trial, dry-run prototype is intended to demonstrate how a larger-scale MSE eventually could be used to evaluate EBFM management strategies for a Georges Bank Ecosystem Production Unit with all stakeholders involved. The Council approved the planning document for this initiative. The presentation and other meeting materials related to the April EBFM discussion are available here.

New Study Develops Method to Age Ocean Quahog, Longest-Lived Species in the Ocean

April 21, 2022 — The following was released by the Science Center for Marine Fisheries:

Ocean quahogs are some of the longest-lived animals in the world, with the oldest specimens in the U.S. Mid-Atlantic regularly recorded at over 200 years old. But even though they are famous for their longevity, many details about the age structure of ocean quahogs—such as how it affects estimates of recruitment, biomass, and growth—are still not well understood. A newly published study finds that ocean quahogs have recruited continuously for over 200 years on Georges Bank, off the East Coast of the U.S., while also providing new tools to researchers and fisheries managers to better understand the species.

Funded by the Science Center for Marine Fisheries (SCEMFIS), the study collected a large sample of ocean quahogs—gathering over 600 specimens—and recorded relevant information on them, including age, length, and sex. Researchers then took that information to develop what’s known as an “age-length key,” which charts the probability of an animal of a given age being a specific length. The key can be used to determine the distribution of ages in a population based on the simple determination of the distribution of lengths.

Currently, ocean quahog models used for management are based on the length of the ocean quahog, rather than its age. Like trees, ocean quahogs can be aged by counting the growth rings that form over time, in this case on its outer shell. But because the process of directly determining an individual ocean quahog’s age is time-consuming and impractical for most larger surveys, length has been used instead as a proxy for age.

The age-length key resulting from this study, given the size of the sample of ocean quahogs collected, is a robust data set that can be consulted to quickly estimate ages of thousands of quahogs using only animal lengths. A reliable age-length key improves the potential to introduce more age-based data into ocean quahog management, making it more consistent with how other species are managed.

“Because ocean quahogs are so long-lived, getting a method to quickly and accurately estimate their age is critically important,” said Kathleen Hemeon, of the Gulf Coast Research Laboratory and one of the authors of the study, which was published in the Journal of the Marine Biological Association of the United Kingdom. “Having this kind of age and length data available can help change the way we manage the species.”

In addition to developing a more comprehensive age-length key, the study had other notable findings that are important in furthering our understanding of ocean quahogs. In the ocean quahogs sampled, the study confirmed that ocean quahogs are a sexually dimorphic species, with female ocean quahogs generally larger than males. It also found that recruitment, or the number of new ocean quahogs that are successfully born into the population every year, has been an annual occurrence since the late 1800s, which is notable given their long lifespans and suspected delayed maturity. In its sampling, the study collected the oldest ocean quahog on record in Massachusetts, at 261 years old.

“This study addresses a conundrum that has bedeviled quahog fishery managers for many years – namely, whether recruitment occurs consistently, or only sporadically in cycles some thirty years apart,” said Tom Alspach, of Sea Watch International, a seafood company based in Maryland. “This evidence of consistent annual recruitment can remove a level of uncertainty from management decision-making, leading to greater confidence in more generous quota setting, with a direct positive impact on industry.”
