Bipartisan fisheries management law would expand eDNA use

September 1, 2026 — Bipartisan legislation introduced this month by the co-chairs of the U.S. Senate Oceans Caucus relies on environmental DNA (eDNA) techniques pioneered by Cornell researcher David Lodge, professor of ecology and evolutionary biology and past director of the Cornell Atkinson Center for Sustainability.

The Fisheries Science Modernization Act would direct the National Oceanic and Atmospheric Administration (NOAA) to incorporate eDNA tools into their assessment surveys of fish stocks – assessments that inform how many fish can be harvested by commercial and recreational fishers. Eight Republican, Democratic and independent senators co-sponsor the legislation, and multiple fishing industry and environmental protection organizations support it.

“When I started testing eDNA 17 years ago, I was interested in detecting rare species, such as emerging invasive species and endangered species,” Lodge said. “The focus of this legislation is quite different. Here, it’s not just about detecting whether a Pacific hake exists, it’s about estimating how many hake there are, based on how many distinct pieces of hake DNA you can find. It’s pretty astonishing to me that we in the scientific world working on eDNA have come this far, this fast.”

Record Cobia Tournament Shows a Chesapeake Predator Thriving Alongside Menhaden

August 31, 2026 — Congratulations are in order for the winners and participants in the 2026 Big Man’s Cobia Bonanza.

The ninth annual tournament was held August 14–15 in the Chesapeake Bay, with events based in Norfolk and weigh-ins at Little Creek. By the organizers’ account, it was a record year, with more than 100 boats participating and a top prize of over $38,000, and two runner-up $12,000 prizes. The organizers summed up the weekend with the declaration: “We put Virginia Cobia fishing in the Chesapeake Bay back on top!”

That is worth celebrating. It is also worth considering in the continuing debate over whether the Chesapeake Bay has enough menhaden to support its predators.

Cobia are large predators that spend the summer feeding in Chesapeake waters. Menhaden are part of their prey base and an important forage fish in the same waters where cobia thrive. Scientists and Bay fishing organizations alike have identified menhaden as an important prey species for cobia, and menhaden have traditionally been a preferred cobia bait.

That makes this year’s tournament particularly interesting; the success of a major Chesapeake predator that consumes menhaden is difficult to reconcile with sweeping claims that the Bay lacks sufficient forage for its predators.

The contrast with striped bass is instructive.

The Atlantic States Marine Fisheries Commission currently classifies Atlantic cobia as not overfished, with overfishing not occurring. Striped bass are also important predators of menhaden, but their stock has followed a different path. In 2024, the peer-reviewed striped bass stock assessment found the stock was overfished. The stock is currently managed with restrictions designed to reduce fishing mortality and rebuild the population.

That history does not mean forage is irrelevant to striped bass, but it does mean discussions about their condition should acknowledge a well-established factor: fishing mortality on striped bass themselves was too high for years.

Menhaden, meanwhile, are already managed with their ecological role in mind. The ASMFC uses ecological reference points specifically designed to account for menhaden as forage and the needs of predators. The Atlantic menhaden stock itself is classified as not overfished, with overfishing not occurring.

Taken together, these facts suggest Chesapeake predator dynamics are more complicated than simply claiming there are not enough menhaden. Cobia and striped bass share the same broader ecosystem and both consume menhaden, yet their stock conditions are very different.

That comparison does not mean menhaden are evenly distributed throughout the Chesapeake Bay or that every predator has equal access to forage at all times. Menhaden are highly migratory schooling fish whose presence in any particular place changes with season, movement and environmental conditions.

Questions about local menhaden movement, seasonal abundance and predator access deserve continued study. And that work is happening.

The federal government, Virginia, and the menhaden industry are all supporting research to better understand menhaden movement, seasonal abundance, predator consumption and fishery interactions in the Chesapeake Bay. Congress has funded Bay-specific research, Virginia has committed funding for work led by the Virginia Institute of Marine Science (VIMS), and the industry is supporting collaborative research involving VIMS, the Chesapeake Biological Laboratory and NOAA.

That is how unresolved questions should be addressed: through cooperative science, not through simple assumptions.

In the meantime, what happened at this year’s Cobia Bonanza deserves attention.

Congratulations to the winners. Their success is a reminder that the Chesapeake Bay forage story may be considerably healthier than some of the rhetoric surrounding menhaden would have us believe.

Meet the Autonomous Underwater Robot Expanding Our Ability to Survey the Seafloor

August 31, 2026 — For the past 3 years, our Habitat Camera (HabCam) Survey has had self-propelled underwater helpers. From June 30 to July 6 of this year, two Tethys-class long-range autonomous underwater vehicles, or LRAUVs, surveyed more than 200 nautical miles of pre-programmed track lines in the Mid-Atlantic. Together, they captured more than 68,000 images of the seafloor, collecting critical data used in fisheries stock assessments.

LRAUVs provide an alternative way to survey areas of the ocean where traditional research vessels cannot go because of offshore development. The data they collect complements our vessel-based HabCam Survey, which collects millions of seafloor images each year to understand Atlantic sea scallop populations.

Technology Strengthens the Sea Scallop Assessment

Our scientists identified sea scallops, fish, crabs, snake eels, squid, skates, and more in the seafloor images taken by LRAUVs this year. They will present these data, along with HabCam Survey data, to the New England Fishery Management Council at the end of August. The Council’s Scallop Plan Development Team will incorporate the data into the Atlantic sea scallop assessment. Ultimately, the data help generate more accurate estimates of sea scallop abundance and distribution to inform management decisions.

Advanced Technology Specialist Cameron Fairclough notes that this technology expands where and when we can collect data. “This autonomous underwater vehicle can image the seafloor and you can control it from your phone while it’s out in the middle of the ocean,” he explained.

NOAA to rebuild historic science lab in Beaufort, North Carolina

August 28, 2026 — Today, NOAA announced plans to fund the reconstruction of a new laboratory in Beaufort, North Carolina. This new lab will replace the former building that was permanently closed in 2024 due to significant hurricane-related structural damage. The project will be funded using $64 million from the 2025 Disaster Relief Supplemental Appropriations Act. Design and preconstruction work is expected to begin in early 2027.

Established in 1899, the NOAA Beaufort Laboratory is the nation’s second-oldest federal marine science laboratory, predating NOAA by more than 70 years. Following a routine inspection, NOAA determined the laboratory sustained foundational damage that made building occupancy unsafe. The new facility will be built above the floodplain and designed to withstand storm and flooding events.

ALASKA: St. Paul’s new research vessel marks a milestone in effort to rebuild local economy

August 28, 2026 — The Pribilof Islands community of St. Paul is now the homeport for a research vessel. The 50-foot Eventide arrived in St. Paul late last month, marking a major milestone for the community.

John Wayne Melovidov is president of the Aleut Community of St. Paul Island Tribal Government. He said St. Paul is working to build a research economy after declines in the local fishing industry. The island’s Trident Seafood plant closed after the Bering Sea crab fishery crashed in 2022. Melovidov said monitoring the area’s crab, halibut and fur seal populations will be especially important.

“If anybody should be doing the research on what’s going on with our species out in our backyard, it should be us,” he said. “So we set up a lab to do that research ourselves, but also to invite other scientists to do whatever research they want to do.”

Beyond the salmon crisis: Northwest may face broad loss of freshwater species

August 27, 2026 — Using eDNA to map and save lower-profile species crucial to the ecosystem, researchers say

According to a recent Convention of Migratory Species Report, migratory freshwater fish populations have dropped 81% worldwide since 1970. While Northwest Washington species face many of the same pressures as other species across the planet, the story here is a bit more nuanced, and researchers point to a unique interagency collaboration in the state as a pathway forward.

Salish Sea Chinook salmon populations are down 60% since the Pacific Salmon Commission began tracking salmon abundance in 1984, according to the 2024 State of Salmon in Watersheds report.

Around the Salish Sea, Chinook salmon provide immense ecological, cultural and economic value. According to the report, Puget Sound was once home to larger populations of Chinook and other salmon, with a greater diversity of traits than populations existing today. Only 22 of at least 37 historic Chinook salmon populations remain in this ecosystem. The remaining Chinook salmon populations are at about 10% of their historic numbers. Between 2000 and 2018, the total number of Chinook returning to the Salish Sea has shown a relatively stable trend.

These salmon populations face the same pressures as freshwater fish listed in the global report: habitat loss, harvest rates and climate change.

“All the research, all the science, all the data that’s been analyzed shows us that habitat is by far the leading threat,” said Annitra Peck, executive director of the Nooksack Salmon Enhancement Association. “You’ve got hydropower, you’ve got harvest management, you’ve got these other pieces that have so much to do with it, and they all definitely intersect, but habitat is in large part the driving concern. Salmon are an anadromous species; they utilize freshwater and saltwater, they need to be able to travel back and forth in their unique life cycle, and if they don’t have the habitat to do that, then that falls apart. It prevents that life cycle from continuing and that reproduction for salmon to be able to replace themselves essentially.”

Mel Allen: Telling the stories of New England

August 25, 2026 — For more than 50 years, Mel Allen has made a career out of telling stories about those in New England.

He has written about fishermen and island communities, sardine packers and chefs, scientists counting fish aboard NOAA research vessels, and people whose livelihoods disappeared as fisheries and working waterfronts changed around them.

So when the former longtime editor of Yankee Magazine stood before a room filled with ocean scientists, researchers, and industry partners at the 2026 Northeastern Regional Association of Coastal Ocean Observing Systems (NERACOOS) Annual Meeting, he came with a message that was surprisingly simple.

Tell people a story.

“If you want people to care about something big, whether conflicts between nations, the dilemma of immigration, or our changing oceans, do not show the topic,” Allen said. “Show how people have been touched by the topic. That’s how we relate to each other.”

For NERACOOS, that message comes at an important moment.

NERACOOS helps coordinate sensors, models, data systems, and other technology used to track conditions across New England’s waters. Now, its work is expanding through the new National Science Foundation (NSF) Seafood Engine in New England, an initiative focused on supporting New England’s seafood industry.

The potentially 10-year initiative is designed to build an innovation network across the seafood supply chain, connecting work on the water with processing, distribution, and the consumer. Its focus includes environmental sensing and modeling, technology development, workforce training, and investment.

For commercial fishermen, that puts an industry accustomed to being on the receiving end of scientific data and management decisions closer to the center of a much broader effort to determine how New England seafood adapts to a changing ocean and economy.

But Allen’s keynote reminded everyone what all that technology and investment is ultimately intended to serve.

Beyond Ocean Mapping: Using Uncrewed Vehicles to Advance Ocean Research

August 21, 2026 —  It’s January off of Nantucket Shoals. An uncrewed surface vehicle begins a series of carefully planned transects through Southern New England, collecting data day and night. There are no scientists onboard, but the 30-foot vessel is constantly measuring ocean currents, water temperature, salinity, weather and other ocean conditions. It’s also helping identify areas with high fish and plankton abundance. Every nautical mile traveled adds to a more complete picture of how marine ecosystems function.

These missions reflect NOAA’s growing use of uncrewed systems technology. Traditionally, these autonomous platforms have supported hydrographic surveys, nautical charting, and ocean mapping. But the benefits extend beyond creating better maps. Today, the same technologies are helping scientists answer complex ecological and oceanographic questions. They’re collecting critical, high-accuracy, and time-sensitive data across nearly every mission area.

“Over the last several years, we have been able to expand the applications for how uncrewed surface vehicles can help with various research related to stock, ecosystem, and protected species evaluations and assessments,” explains Dr. Conor McManus, marine development and advanced technology program lead for the Northeast Fisheries Science Center. “With each mission we conduct, we are learning more about the Northeast U.S. Shelf ecosystem, but also how we can better operationalize these technologies to meet our scientific or data needs.”

These technological advances are expanding where, when, and how our scientists collect ocean data. The results allow researchers to observe the ocean more continuously and in places that are difficult to sample with ships alone. These vehicles complement ship-based surveys—filling gaps in data that can arise from challenges like winter weather and limited ship availability.

This year, there were three uncrewed surface vehicle missions in the Northeast—two operated by Chance Maritime Technologies and one using DriX. They demonstrated how the benefits of uncrewed survey technology can answer many different scientific questions.

A Winter at Sea Reveals Seasonal Habits of Whales, Dolphins, and Seabirds in Hawaiʻi

August 21, 2026 — The Hawaiian archipelago is teeming with marine life, and winter brings some of the most exciting activity of the year. It’s a season when many whale and seabird species travel to the islands. Migratory baleen whales such as humpback and minke whales are only found in Hawai‘i in the winter, when they seek warmer waters to breed. Others—including various types of dolphins—rely on this marine ecosystem year-round, but scientists have yet to uncover the details of their wintertime habits.

To close that gap, the Pacific Islands Fisheries Science Center launched a survey in late January 2026. Scientists spent 2 months monitoring these species around the main Hawaiian islands aboard the NOAA Ship Oscar Elton Sette. The mission, called the Winter Hawaiian Islands Cetacean and Ecosystem Assessment Survey, is only the second of its kind.

Six years after the first winter survey, researchers returned to better understand where, when, and how many whales and dolphins use this habitat. The data from these surveys feed into stock assessments, helping us track the status of these species and make informed conservation decisions. This work is especially important for high-priority species like false killer whales, including an endangered population that lives around the main Hawaiian islands.

Winter conditions at sea can be rough, with higher swells and lots of white caps. This makes animals harder to see. But NOAA scientists are experienced with scientific methods that rise to the challenge. During the survey, eagle-eyed visual observers spied more than 200 groups of whales and dolphins, even in difficult conditions. They documented humpback mothers with their calves, bottlenose dolphins riding the ship’s bow, and pantropical spotted dolphins leaping high into the air. Cutting-edge passive acoustic technology helped detect other whales and dolphins that could be heard but not seen.

In these photos, take a look behind the scenes of the survey and find out which species spend their winters in Hawaiʻi.

Businesses, NGOs pushing for IATTC to adopt management procedures for tropical tuna

August 21, 2026 — Businesses and environmental NGOs are both working to push the Inter-American Tropical Tuna Commission (IATTC) into adopting its first-ever management procedures for tuna at its next meeting, which starts on 24 August.

Groups have been pushing the regional fishery management organization (RFMO) to adopt management procedures for multiple species it governs. Management procedures, also called harvest strategies, are a means of setting predetermined triggers on how a species is managed so that an RFMO has a clear roadmap for how to adjust fishing effort based on what surveys and scientific analysis of a stock indicate.
