Climate modelers add ocean biogeochemistry and fisheries to forecasts of future upwelling

January 27, 2023 — A handful of hyper-productive fisheries provide sustenance to a billion people and employ tens of millions. These fisheries occur on the eastern edges of the world’s oceans—off the West Coast of the U.S., the Canary Islands, Peru, Chile, and Benguela. There, a process called upwelling brings cold water and nutrients to the surface, which in turn supports large numbers of larger sea creatures that humans depend on for sustenance.

A new project led by researchers at Texas A&M University is seeking to understand how changes to the climate and oceans will impact fisheries in the U.S. and around the world.

“We’re interested in how is going to alter upwelling and how the sustainability of the future fisheries will be impacted,” said Ping Chang, Louis & Elizabeth Scherck Chair in Oceanography at Texas A&M University (TAMU). “It turns out that when we increase the resolution of our , we find that the upwelling simulation becomes much closer to reality.”

Funded by the National Science Foundation (NSF), the project aims to develop medium to long-term fishery forecasts, driven by some of the highest-resolution coupled climate forecasts ever run. It is one of the 16 Convergence Accelerator Phase 1 projects that address the ‘Blue Economy’—the sustainable use of ocean resources for economic growth. Convergence projects integrate scholars from different science disciplines.

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).

Potential for fisheries co-management shaped by interplay between formal, informal institutions

September 25, 2020 — The following was released by the National Science Foundation:

Integrating local norms and fishers’ knowledge into regulations helps increase trust in management institutions, and can make it easier for co-management to work.

Those were the findings of U.S. National Science Foundation-funded research by University of Maine researchers Kara Pellowe and Heather Leslie. The scientists looked at the interplay between formal and informal institutions and implications for the co-management potential of a small-scale Mexican fishery.

The journal Marine Policy published their results.

Pellowe and Leslie contend that conflicts between formal institutions, such as government agencies, and informal institutions, such as unwritten agreements among families and friends, can represent a significant barrier to effective fisheries management.

They examined the potential for co-management, where power and decision-making are shared by fisheries managers and fishers, in a fishery that is currently managed through top-down control. They concluded that integrating local norms and knowledge into formal regulations, along with broadened community participation, are necessary precursors to co-management. Doing so would result in more successful fisheries management.

Pellowe regularly traveled to Baja California Sur, Mexico, to work closely with fishers, managers and stakeholders in the Mexican chocolate clam (Megapitaria squalida) fishery in Loreto Bay National Park, on the Baja peninsula.

Like the Maine lobster, the Mexican chocolate clam is a culturally and economically important species, providing food, income and cultural value to many communities in Baja.

Project to study pandemic impacts on Alaskan salmon season

June 29, 2020 — The following was released by Penn State:

Bristol Bay, Alaska is home to the world’s largest commercial sockeye salmon fishery, attracting thousands of fishermen, crews, and seasonal workers and tripling the region’s population. Running from early June to late July, the short salmon season is facing a new challenge this year, the coronavirus pandemic.

Penn State is part of a research team conducting surveys with fishery participants and residents to better understand the costs and benefits of varied mitigation policies and is developing pandemic preparedness scenarios. This collaborative project is being funded by a $200,000 National Science Foundation RAPID Response grant.

The concern for this year’s fishing season stems from the 13,000 commercial fishers, crew, and fish processor workers who are descending upon the Bristol Bay region. The largest hospital in the region only has 16 beds and two ventilators and, as of May 2020, was not prepared for an outbreak of coronavirus.

Because the overall economic value of the fishing season is estimated to be around $1.5 billion dollars and the region is dependent on the fishing industry, canceling the season is not economically feasible.

Science Center for Marine Fisheries Funds Over $173,000 in New Research

June 8, 2020 — The following was released by the Science Center for Marine Fisheries:

At its spring meeting, the Science Center for Marine Fisheries (SCEMFIS) approved 6 new research projects and awarded $173,547 in funding. Coming as the fishing industry continues to deal with the fallout of the COVID-19 crisis, the projects funded by the Center deal with some of the most economically important issues for the future of the industry.

These projects include efforts to study how offshore windfarms impact marine life; how to improve stock assessments for one of the largest fisheries in the country; and how to better use shellfish byproducts as commercial products. All projects were approved by the SCEMFIS Industry Advisory Board (IAB), which is composed of Center members in the finfish and shellfish industries. The SCEMFIS IAB encourages companies with an interest in promoting sustainability in the industry to consider joining.

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.

The following projects were approved at the spring meeting:

  • Wind energy development team supporting fisheries – As offshore wind farms continue to expand, they will increasingly interact with critical fish species and ocean habitats. Understanding these interactions and assessing their impacts is essential to future coexistence between offshore wind and fisheries. The project, by Dr. Eric Powell (University of Southern Mississippi), will assemble a wind energy team with diverse areas of expertise to advise SCEMFIS members on potential environmental impacts for offshore development. ($20,200 in funding)
  • Could federal wind farms influence continental shelf oceanography and alter shellfish larval dispersal? A literature review – With over 1.7 million acres of federal waters under lease for wind energy development, new wind energy structures have a significant potential to interfere with ocean conditions, including in critical areas such as how shellfish larvae are dispersed. The project, by Dr. Daphne Munroe of Rutgers University, will review existing literature to determine how wind energy development has affected different oceanographic conditions, and prepare a report on these findings for the public. ($17,791 in funding)
  • Developing process and procedures for the refinement of surfclam and ocean quahog shells into calcium carbonate – Calcium carbonate is an important shellfish byproduct, used in animal feed, biomedical products, and other applications. Because of their chemical composition, quahog and surfclam shells are an especially good source of calcium carbonate compared to other shellfish, such as oysters. The project, by Dr. Alireza Abbaspourrad (Cornell University), will develop a process to tailor the carbonate byproduct to its other uses. ($50,000 in funding)
  • Evaluation the impact of plus group definition on the Atlantic and Gulf Menhaden stock assessments –Atlantic and Gulf menhaden are, by volume, two of the largest fisheries in the U.S. But one major source of uncertainty in its stock assessments are the number of older fish in the population. These fish are inadequately assessed by current surveys. The project, from Drs. Genevieve Nesslage (University of Maryland), Robert Leaf (University of Southern Mississippi), and Amy Schuler (National Marine Fisheries Service), will create a new model to simulate how different levels of these older fish would impact the results and accuracy of the menhaden stock assessments. ($53,414 in funding)
  • Atlantic menhaden stock review – The project, by Dr. Steve Cadrin (University of Massachusetts Dartmouth), will provide a technical review of the Atlantic States Marine Fisheries Commission’s stock assessment for Atlantic menhaden, as well as provide a new analysis of estimated rates of menhaden natural mortality, and the percentage of the population that is allocated for ecosystem needs. ($3,520 in funding)
  • Retention of Expertise in SS-III and evaluation of past and predictive modeling of future stock status – Stock assessments for ocean quahog and surfclams rely on a specific modeling tool, the Stock Synthesis V3. The project, from Drs. Eric Powell (University of Southern Mississippi) and Roger Mann (Virginia Institute of Marine Science) will recruit a Ph.D. student to train to use the model, with the goal of maintaining scientific expertise in using and understanding it. ($28,622 in funding)

University of New England Shares NSF Grant on Lobsters and Climate Change

April 7, 2020 — A study on how warming ocean water impacts the early life stages of lobster will bring together two undergraduate colleges, a premier research institution, and a state agency.

The University of New England applied for the $860,000 grant from the National Science Foundation (NSF) and intends to share it with Hood College in Maryland, Bigelow Laboratory for Ocean Sciences, and the Maine Department of Marine Resources.

Warming Gulf of Maine waters may be stunting lobster growth

April 2, 2020 — The Gulf of Maine is warming faster than 99% of the world’s oceans. And the trend may be having an impact on Maine’s most valuable commercial fishery, if temperature affects lobster larvae and their success in growing to adulthood, scientists say.

The University of New England in Biddeford, Bigelow Laboratory for Ocean Sciences in East Boothbay, the Maine Department of Marine Resources and Hood College in Frederick, Md., have received an $860,000 grant from the National Science Foundation to study that impact.

“We’ll be studying how temperature influences how larvae settle, where they settle and how successfully they settle,” Markus Frederich, a UNE marine science professor helping to lead the project, said in a news release Tuesday. “The findings of this project will help us make more specific predictions of how many lobsters there will be in the Gulf of Maine in the future.”

Maine’s lobster catch was valued at $485.4 million last year, when Maine lobster harvesters landed 100.7 million pounds. It was a 17% decline compared with 2018, but landings still topped the 100-million-pound mark for the ninth year in a row.

Science Center for Marine Fisheries heads into 2020 with $190,000 in funding for new projects

January 23, 2020 — The following was released by the Science Center for Marine Fisheries:

The Science Center for Marine Fisheries (SCeMFiS) has approved over $191,000 in funding for new research projects in 2020. SCeMFiS researchers from across the country will kick off the decade tackling some of the most pressing issues affecting our oceans, including the effects of climate change, marine mammal interactions, and bycatch.

SCeMFiS, part of the National Science Foundation’s Industry-University Cooperative Research Centers (IUCRC) program, brings together scientific institutions and their partners in the fishing industry to address urgent needs in finfish and shellfish science. All funding and research priorities are determined on a collaborative basis between SCeMFiS scientists and participating industry members.

The following 2020 research projects were approved at the Center’s 2019 fall meeting.

  • Evaluation of the degree of co-occurrence of surfclams and ocean quahogs at fishable concentrations – Climate change is beginning to affect how fisheries are managed, and regulators will increasingly need to modify existing rules in order to adapt to it. In the case of surfclams, climate change is pushing them out of their traditional habitats, where they are beginning to overlap with ocean quahogs. Since neither species can be harvested together, this overlap has the potential to negatively impact both fisheries. The study, led by Drs. Eric Powell (University of Southern Mississippi) and Roger Mann (Virginia Institute of Marine Science), will examine the extent to which surfclam and quahog habitats currently overlap, and the extent to which this overlap is relevant for management. ($85,899 in funding)
  • Evaluation of gray seal-fishery interactions in US waters of the western North Atlantic – Limiting bycatch and interactions with marine mammals is critical to many fisheries in the northeastern U.S. The study, led by Dr. Doug DeMaster (Marine Analytical Consultants), will develop a new, cross-jurisdictional seal population dynamics model to help the National Marine Fisheries Service determine the extent of gray seal fishery interactions, as well as recommending other research priorities for gray seal management. ($57,420 in funding)
  • Mid-Atlantic discard analysis – Bycatch remains a persistent issue in several Mid-Atlantic fisheries, and understanding the factors that may contribute to bycatch is a top priority for both fishermen and regulators. The study, from Dr. Robert Leaf (University of Southern Mississippi), will examine four fisheries—scup, Loligo squid, black sea bass, and fluke—and determine which factors may correlate to higher rates. ($43,439 in funding)
  • Atlantic Menhaden stock assessment review – By weight, Atlantic menhaden is one of the largest fisheries on the East Coast, supporting both a large bait and marine ingredients industry. The study, from Dr. Steve Cadrin (University of Massachusetts Dartmouth) will undertake a review of the menhaden assessment by the Atlantic States Marine Fisheries Commission, providing a non-technical summary for stakeholders in the menhaden fishery to support science-based management of the fishery. ($4,400 in funding)

Sens. Ed Markey and Dan Sullivan introduce bipartisan bill to boost ocean health

October 28, 2019 — Democratic Sen. Ed Markey of Massachusetts and Republican Sen. Dan Sullivan of Alaska on Friday introduced the Ocean, Coastal and Estuarine Acidification Necessitates (OCEAN) Research Act, which boosts investment in research that could improve ocean health and protect the seafood industry.

The senators said in a news release Friday that the bill would lead to greater research and monitoring of ocean acidification, which occurs as a consequence of carbon dioxide forming acids when dissolved in seawater. The process harms shellfish, coral reefs and other marine life essential for healthy ecosystems and coastal economies.

In coastal areas, acidification may interact with warming waters, harmful algal blooms and low-oxygen “dead zones” with severe impacts. Southern Massachusetts and Narragansett Bay have been identified as “acidification hotspots,” jeopardizing the $500 million-plus Massachusetts shellfish industry.

The bipartisan bill introduced Friday would reauthorize the Federal Ocean Acidification Research and Monitoring Act, which lapsed in 2012 and provided funding for the National Oceanic and Atmospheric Administration (NOAA) and the National Science Foundation. The bill calls for engaging with coastal communities and the seafood industry through an advisory board and research grants.
