Climate change impacting Atlantic shellfish, and scientists predict it will only get worse

July 25, 2022 — A team of researchers form the Science Center for Marine Fisheries, an organization with a number of partners and collaborating scientists from universities like the Virginia Institute of Marine Science, is examining how warmer waters will impact shellfish species harvested in the United States.

The research, centering on ocean quahogs and surfclams, is examining how the two species will begin to interact as changing ocean conditions cause the species to shift habitats. Ocean quahog are one of the longest-lived marine species in the world and inhabit cold waters in the Mid-Atlantic, while surfclams typically inhabit warmer areas.

Climate Change Creating New Conflicts for Surfclam, Ocean Quahog Fisheries as Warming Forces Habitat Shifts

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

Climate change is now affecting long-standing patterns for marine life, with warmer waters pushing species out of their traditional habitats and into newer areas. As these changes become increasingly common, they will create challenges for fishermen, scientists, and regulators. A team at the Science Center for Marine Fisheries (SCEMFIS) is examining the extent of the problem on two key shellfish species: surfclams and ocean quahogs.

Ocean quahogs, one of the longest-lived marine species on Earth, inhabit cold waters in the Mid-Atlantic; surfclams, in contrast, have traditionally inhabited warmer areas. With climate change, surfclams’ traditional habitats have become some of the fastest-warming waters in the region, forcing them to move north into the colder waters traditionally occupied by quahogs.

“The area of overlap is getting potentially larger and larger as the Middle Atlantic warms, because one species is moving in, and the other one hasn’t quite got the message and moved out yet,” said Dr. Roger Mann of the Virginia Institute of Marine Science, one of the lead scientists on the survey.

In the fall of 2021, a team from SCEMFIS partnered with an industry fishing vessel, the F/V Pursuit, to document the extent of this habitat overlap. They took samples in several areas, working through surfclam and ocean quahog habitats, as well as areas of intermingling in between. The team documented what was caught, its species, size, age, and location.

After analyzing the data, the team found significant habitat overlap and intermixing between surfclams and ocean quahogs, much more than was expected at the start of the survey.

“One of the surprises though was just how extensive the overlap is now,” said Dr. Eric Powell, of the University of Southern Mississippi, another one of the survey’s lead scientists. “This is a major community shift on the continental shelf and it’s something that the management agencies and the fishery are going to have to get their arms around and deal with.”

Intermixing of ocean quahogs and surfclams is just the latest example of how climate change is creating new problems for fishermen. Under current rules, fishermen are not allowed to harvest clams and quahogs at the same time. In an environment where these species inhabited separate parts of the ocean, these rules were easy for fishermen to comply with. But climate-influenced migration is making harvesting these species much more challenging, a problem that will only increase in importance as trends continue.

“As bad as it is, it’s going to be much worse in five years, in my opinion,” said Dr. Powell. “The challenge, both to the fishery and management, is to figure out how to revise the regulations so both of these species can be landed without causing a problem with the inherent stability of the fishery and management.”

“The information that we get is vitally important to us staying not only a sustainable fishery, but also a fishery in good stead with enforcement,” said Guy Simmons, Senior Vice President at Sea Watch International, which harvests clams and is a member of the SCEMFIS Industry Advisory Board.

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.”

New study offers improvements to estimating shellfish populations

March 14, 2022 — The following was released by the Science Center for Marine Fisheries:

A new study, jointly conducted and funded by the Science Center for Marine Fisheries (SCEMFIS) and the National Marine Fisheries Service (NMFS), finds ways to reduce a source of uncertainty in the Atlantic surfclam and ocean quahog population estimates: defining the efficiency of the survey gear. The study, published in Fishery Bulletin, is part of the Center’s long-running efforts to improve our understanding of shellfish.

The dredge efficiency issue, which dates to the early 1990s, is about how effective clam research survey vessels are at catching surfclams and ocean quahogs. The efficiency of a clam dredge—which is a measure of the proportion of Atlantic surfclams or ocean quahogs on the ocean floor that a dredge can catch—is one of the key variables in stock assessment population estimates. The efficiency of the dredge is a primary factor affecting the biomass estimate of the stock and therefore an important criterion determining how the assessment evaluates the status of the stock relative to management goals.

One way researchers measure efficiency is through field depletion experiments, where a dredge is run multiple times in a single area to measure the percentage of available shellfish it caught with each tow. These experiments are used in both the Atlantic surfclam and ocean quahog assessments to help estimate their dredge efficiencies. There is no way to know what true dredge efficiency is, but conducting many depletion experiments allows scientists to make a reasonable estimate.

The first depletion experiment was conducted in 1997 as a joint effort between NMFS, academic scientists, and the clam fishery. This team carried out many such studies over the following 15 years, making this one of the longest running successful collaborations of this type. This recent study addresses the remaining uncertainty surrounding dredge efficiency by looking at data from this large set of depletion experiments conducted over two decades and examines the quality of these experiments and the efficiency estimates they produced. Specifically, the study took a close look at simulated depletion experiments, where scientists know what the true dredge efficiency is, to identify common characteristics of studies that do a good job estimating dredge efficiency compared to those that do a poor job.

By focusing on the “best” experiments and identifying field experiments that potentially produced inaccurate efficiency estimates, scientists can refine the set of depletion studies used to help estimate efficiency in stock assessments. This refined set of depletion studies has particular influence on non-model-based biomass estimates, which play an important role in verifying the model-based results and are commonly used in management. Once identified, characteristics of good and bad depletion experiments can also inform methodology used in future experiments.

“Identifying field depletion experiments with accurate efficiency estimates helps confirm present stock assessment models’ gear efficiency estimates,” said Leanne Poussard, of the University of Southern Mississippi’s Gulf Coast Research Laboratory and the lead author of the study.

“Ms. Poussard’s work has rekindled interest in the cooperative depletion experiment dataset and produced important guidance for anyone undertaking similar experiments in the future”, said Dr. Dan Hennen of NMFS.

SCEMFIS: New Survey Will Help Fill Gaps in Menhaden Count in New England, Mid-Atlantic

January 14, 2022 — The Science Center for Marine Fisheries (SCEMFIS) highlighted a new project that will look to count a population of menhaden that could help inform not only a local New Jersey fishery but other fisheries in New England and the Mid-Atlantic region.

A team from the University of Maryland Center for Environmental Science’s (UMCES) Chesapeake Biological Laboratory and the Virginia Institute of Marine Science, in collaboration with NOAA Fisheries are on the verge of launching a winter population survey of menhaden, specifically off the coast of New Jersey, SCEMFIS said.

That area is home to a growing winter bait fishery but because there hasn’t been much work to survey the population that far north, there is not a strong enough count of how many fish are in that area.

The survey, which will launch from Cape May, New Jersey, will use sonar equipment to estimate the number of menhaden schooling in the area, and will collect additional information to estimate age, size, and weight, data that will be important for managing the fishery, per SCEMFIS.

Science Center for Marine Fisheries Approves $126,000 in New Research for 2022

January 3, 2022 — The following was released by the Science Center for Marine Fisheries:

The Science Center for Marine Fisheries (SCEMFIS) has funded $126,000 in new marine science research for 2022. The funds, approved by the members of the Center’s Industry Advisory Board at its annual fall meeting, will support new, much-needed research on prominent fisheries such as thread herring, ocean quahogs, squid, and surfclams.

Part of the National Science Foundation’s Industry-University Cooperative Research Centers program, SCEMFIS connects marine scientists with members of the fishing industry to identify scientific priorities for better understanding commercially important fish species, and directs industry funding to projects that study them. Since its founding, SCEMFIS has promoted research that has increased our understanding of these species, and improved their management.

The following research projects were approved by SCEMFIS for 2022:

Biostatistical and fishery-dependent sampling of Atlantic thread herring and Atlantic chub mackerel in the mid-Atlantic region – As a result of climate change and the subsequent migration of fish stocks, a fishery for Atlantic thread herring is developing in the Mid-Atlantic. As part of that development, fisheries managers need better biological data on the species in order to manage it sustainably. This project, led by Dr. Robert Leaf (University of Southern Mississippi), will conduct a sampling survey of thread herring to collect data on the fish being harvested by the fishery, including factors such as age, length, and weight. ($69,336 in funding)
Ocean quahog population dynamics: project completion – SCEMFIS researchers have worked extensively at expanding our understanding of ocean quahog, especially work in charting the age frequencies for quahogs in the Northwest Atlantic, as well as measuring the uncertainty that comes with estimating the age-at-length of quahogs. This project, led by Dr. Eric Powell (University of Southern Mississippi), and Dr. Roger Mann (Virginia Institute of Marine Science), will complete the Center’s ongoing work on ocean quahog, finishing and publishing current unpublished research on quahog age frequencies. ($41,210 in funding)
Genetic and age structure of Southern surfclams – The surfclam fishery has recently resumed fishing in the waters off the coast of Virginia in a region where high bottom water temperatures have led to the deaths of most Atlantic surfclams during much of the 2010s. Increased survival recently may be due to recruitment of the Southern surfclam. To better understand how and why surfclams have returned to this area, this project, led Dr. Daphne Munroe (Rutgers University), will conduct genetic testing on a sample of clams from the area. The tests will help determine their relationship with the rest of the coastwide Atlantic surfclam stock. ($10,795 in funding)
Squid age estimation using CAT Scan technology – A recurring challenge in managing squid is the lack of demographic data available to estimate the ages of the squid in the population. This project, led by Dr. Roger Mann, (Virginia Institute of Marine Science), will evaluate the use of CAT scan technology as a tool to age squid. The scans will be used to measure the size of squid statoliths, which are the hard structures in squid heads that grow over time, and attempt to age the squid based on these measurements. ($5,000 in funding).

Ahead of Magnuson-Stevens Act Hearing, Studies Question Need for Additional Forage Fish Restrictions

November 16, 2021 — Editor’s note: The following was released ahead of today’s House subcommittee hearing on the Forage Fish Conservation Act. Watch the full hearing here.

Today, the House Natural Resources Committee Subcommittee on Water Oceans and Wildlife will hold a hearing on H.R. 5770, the Forage Fish Conservation Act, which would impose new rules on how fisheries managers regulate certain small, schooling, short-lived, pelagic fish and invertebrates that serve as food sources for larger predator species. Two recent studies have raised questions about the need for additional restrictions, and point to existing provisions in the Magnuson-Stevens Act (MSA) that are already ensuring the sustainability of “forage fish” and the species that depend on them.

In addition to the Forage Fish Conservation Act, the subcommittee will consider two bills that would reauthorize and amend the Magnuson-Stevens Act (MSA). H.R. 4690 is the Democratic Majority’s re-authorization of MSA, sponsored by Subcommittee Chair Jared Huffman (D-California) and H.R. 59, sponsored by Rep. Don Young (R-Alaska).

Proponents of the Forage Fish Act point to the need to keep forage fish populations at extra-precautionary levels, above existing overfishing limits, so that they can better provide for the needs of predator species. But a study released this summer in the journal Conservation Biology, and funded by the Science Center for Marine Fisheries (SCEMFIS), found that, for many predator species, managing forage species at these levels are unlikely to bring additional conservation or environmental benefits. This is especially true in already well-managed and well-monitored fisheries, such as those in the U.S. managed under the existing Magnuson-Stevens Act.

“Management of forage fish populations should be based on data that are specific to that forage fish, and to their predators,” said Dr. Olaf Jensen of the University of Wisconsin-Madison, one of the study’s authors. “When there aren’t sufficient data to conduct a population-specific analysis, it’s reasonable to manage forage fish populations for maximum sustainable yield, as we would other fish populations under the Magnuson-Stevens Act.”

Dr. Jensen and his co-author Dr. Chris Free of the University of California Santa Barbara discuss the results of the paper at greater length in a video released earlier this year. They are joined by scientists Dr. Doug Butterworthof the University of Cape Town, and Dr. Éva Plagányi of CSIRO Oceans and Atmosphere, who offer their independent assessment of the study and their own conclusions on its findings.

To reach these conclusions, the study examined decades worth of abundance data for 45 different predator species and their prey, and found that only 13 percent of them showed any positive impact from having additional, higher levels of forage. Instead, it found that other environmental factors have a far greater influence.

The results of the study reinforce the conclusions of an earlier 2017 study published in Fisheries Research, which found that the fishing of forage fish species had a much smaller impact than previous studies had indicated, and that forage fish were best managed on a case-by-case basis, rather than on broad rules applied across species.

New Study Develops Alternate Methods to Manage Gray Seal Bycatch

September 27, 2021 — The following was released by the Science Center for Marine Fisheries:

Marine mammal conservation is one of the top goals of U.S. ocean management. That is why it’s particularly important for regulators to have an accurate estimate of how fisheries and other ocean users may impact marine mammal populations. A new study looks at ways of strengthening and fine-tuning existing marine mammal management and assessing the impacts on one marine mammal population in the western North Atlantic, the gray seal.

The study, from Drs. André Punt, John R. Brandon, Doug DeMaster, and Paula Moreno, is the culmination of a 3-year research project led by Dr. DeMaster and conducted in collaboration with the scientists at NOAA’s Northeast Science Center, with funding from the Science Center for Marine Fisheries. It specifically examines a key variable in marine mammal management, the Potential Biological Removal (PBR) level.

Under the Marine Mammal Protection Act, marine mammal populations are managed according to their Potential Biological Removal (PBR), which determines the level of mortality (and serious injury) that is sustainable for each marine mammal population. When bycatch of a marine mammal population nears or exceeds its PBR level, restrictions are often imposed on nearby fisheries as a precautionary measure to prevent the population from becoming depleted.

In the case of gray seals, assessments of human-caused mortality levels are complicated by the fact that the gray seal population exists on both sides of the U.S.-Canada border. Determining when the gray seal PBR is exceeded is subject to errors due to incomplete information, meaning that certain management decisions could unnecessarily trigger fishing restrictions (termed by scientists as ‘false positives’) or needed restrictions are not imposed (known as ‘false negatives’). These restrictions often include catch limits of commercially valuable species, limits on what kinds of gear can be used, and other regulations that can be costly for the fisheries forced to adopt them.

To address this, the authors assembled the best available data on the western North Atlantic grey seal population and Canadian fisheries. This allowed them to produce two key estimates when assessing whether gray seal bycatch exceeds the PBR level. It used a more realistic, species-specific rate of gray seal maximum net production (i.e., 14.1% per year), rather than using a generic default value for other seal species (12% per year). If adopted by the National Marine Fisheries Service (NMFS), this would increase gray seal PBR level by 18%. The study also used an extrapolated bycatch estimate for adjacent Canadian waters, which had not previously been attempted.

The study found that, in comparison to the base model currently used by NMFS, this approach is more robust to transboundary movements and uses a more accurate estimate of maximum net production of gray seals, allowing managers to adopt more appropriate management measures on fisheries while still achieving precautionary conservation goals for the grey seal population. The results can provide a blueprint for other assessments of marine mammal-fishery interactions for similar transboundary marine mammal stocks.

Jersey Shore’s fishing industry wonders: Can it coexist with planned massive wind farms?

September 24, 2021 — As part of the Biden administration’s commitment to tackling climate change, it wants to develop 30,000 megawatts of offshore wind power by 2030 — enough to light up 10 million homes. Only two small wind farms now exist in the United States: the five-turbine farm off the coast of Block Island, Rhode Island, operated by a unit of the Danish energy company Orsted, and a small pilot project in Virginia operated by Dominion Energy. The Bureau of Ocean Energy Management, or BOEM, has already awarded 17 lease areas between Massachusetts and North Carolina, and this year it added another eight between Long Island and Cape May.

New Jersey was awarded the largest leasing area yet: Hundreds of turbines will rise more than 80 stories tall, like a forest of steel bolstered by a bed of rocks on the seabed and stretching over hundreds of thousands of acres 10 to 15 miles from shore.

[Tom] Dameron says clammers will compete for a smaller patch of ocean.

“It’s going to lead to localized overfishing,” he says, “which will lead to the boats targeting smaller and smaller clams, which has the potential to lead to the collapse of this fishery in Atlantic City.”

Researchers, funded by a mix of grants from the fishing industry, the New Jersey Board of Public Utilities, the Department of Energy, and the wind industry, are racing to figure out what this massive industrialization — which includes 1.7 million acres of lease area along the East Coast and more than 1,500 structures in the seabed — will mean for fisheries, marine mammals, and ecosystems.

“From my perspective as a fishery scientist, that’s a lot of ocean and a lot of fisheries and a lot of marine habitat that is on the table,” says shellfish ecologist Daphne Monroe, who works at Rutgers Haskin Shellfish Research Lab. “So it’s a lot to think about.”

Monroe recently had to shift her focus to the impact of wind. Her computer modelling shows fishermen like Dameron and [Charlie] Quintana are right to be fearful.

Another fear is what could happen to a unique feature of New Jersey’s coastal fishery — the “cold pool.” Though surface waters warm each summer, lower parts of the mid-Atlantic ocean don’t mix very much with the warmer surface waters unless there’s a strong storm like a hurricane. So that deeper, colder water acts as a refrigerator for species like clams and scallops, along with bottom fish like summer flounder, or fluke.

In fact, the same ecosystem that makes fishing along the Jersey coast so lucrative, its flat sandy bottom, makes it ideal to construct a wind farm. But it’s unclear whether the wind turbines will affect that mix of ocean temperatures for better or for worse. Or whether they will shift migration patterns.

Travis Miles, a meteorologist and physical oceanographer at Rutgers University, says that in the summertime, the mid-Atlantic ocean is one of the most highly stratified and stable water columns. Warm on top, cold on the bottom, with very little mixing. He says that we can learn some things from the large wind farms that have been built in the North Sea, but that it’s a very different ecosystem.

“Europe has very strong tidal currents,” he says. “Tides happen every day, twice or more, and those strong currents can cause mixing, the faster the water goes past a structure the more mixing. The mid-Atlantic has very weak tides, what usually causes mixing are very strong storms, cyclones, or nor’easters.”

The Science Center for Marine Fisheries funded Miles to do research on both the impact of the North Sea wind farms and local impacts. He recently published his results in a peer-reviewed journal, Marine Technology Journal.

Science Center for Marine Fisheries Approves $180,000 in New Funding for Fisheries Research

July 15, 2021 — The following was released by the Science Center for Marine Fisheries (SCEMFIS):

The Science Center for Marine Fisheries (SCEMFIS) has approved 5 new research projects for 2021, awarding over $180,000 in funding for finfish and shellfish projects. Approved by the Center’s Industry Advisory Board (IAB), the projects have been identified by the Center’s industry partners as addressing critical scientific needs in their fisheries.

These projects include assessing the economic impact of menhaden fisheries; developing processes for shellfish refinement; improving finfish stock assessments; mitigation proposals for surfclam hatcheries; and analyzing the age and length composition of ocean quahog.

The following projects were approved and funded:

Developing process and procedures for the refinement of surf clam and ocean quahog shells into calcium carbonate – Waste produced by the used shells of clams and ocean quahogs are considered environmentally hazardous; finding ways to effectively deal with it is an important sustainability issue. The project, headed by Dr. Alireza Abbaspourrad (Cornell University), will focus on turning shell waste into a value-added product, contributing to blue economy efforts and promote sustainability. ($110,950 in funding)

Mid-Atlantic management track stock assessment – Led by Dr. Steve Cadrin (UMass Dartmouth), this study will update stock assessments for Atlantic mackerel, summer flounder, scup, black sea bass, bluefish, and golden tilefish. The project will improve both the understanding and effectiveness of finfish stock assessments and stakeholder involvement in finfish management. ($3,520 in funding)

What hatchery capacity would be needed to support surfclam fishery mitigation via seeding fishing grounds? – Currently, the United States has over 1.7 million square acres of federal waters under lease for wind energy. These wind projects will reduce access to surfclam grounds and potentially impact surfclam hatcheries and nurseries. This study, by Dr. Daphne Monroe (Rutgers University), will evaluate mitigation strategies and other ways to support fishing communities as offshore wind energy continues to expand. ($18,480 in funding)

Evaluation of ocean quahog aging program for providing age data for the assessment; identification of status, uncertainty, and additional research needs – Ocean quahogs are the oldest and longest-lived animals under federal management, making them particularly vulnerable to the impacts of climate change. Partnering with the Northeast Fisheries Science Center, Dr. Eric Powell (University of Southern Mississippi) and Dr. Roger Mann (Virginia Institute of Marine Science), SCEMFIS has funded a research program to improve understanding of quahog population dynamics, recruitment, and growth rates. The present project will fund a workshop to review findings and evaluate the application of SCEMFIS findings to the NMFS-NEFSC assessment program. ($29,552 in funding)

Menhaden economic impact and management uncertainty – Led by Dr. Thomas J. Murray (Virginia Institute of Marine Science), this project focuses on developing an economic input-output model for the menhaden fishery. The development of this model will allow management decisions to be informed by economic impacts associated with catch and catch area controls. ($34,500 in funding)

SCEMFIS is a member of the National Science Foundation’s Industry-University Cooperative Research Centers (IUCRC) program, a federal initiative to bring together academic researchers and industry members to fund projects improving our understanding of economically important issues.
