TRCP Misrepresented Key Menhaden Facts on the Tom Rowland Podcast

October 23, 2026 — The following was released by the American Small Pelagics Network:

Jaclyn Lunaas and Chris Macaluso of the Theodore Roosevelt Conservation Partnership gave listeners a materially misleading account of menhaden science and management across both the Atlantic and Gulf fisheries. This ranges from Atlantic menhaden and Chesapeake Bay issues to Gulf menhaden in the Gulf of Mexico, along with claims involving striped bass, osprey, red drum, spotted seatrout, king mackerel, tarpon and other species. Host Tom Rowland largely accepted their claims rather than testing them against readily available fisheries data and the published record of the relevant management agencies. The result was a discussion in which advocacy was repeatedly presented as settled science.

Lunaas said scientists had been overestimating coastwide biomass by about 40% and implied the catch limit had therefore been “way too high.” But the ASMFC says the revision primarily reflected a new estimate of natural mortality that rescaled the historical population; it was not a 40% population collapse. Total biomass “has actually slightly increased since 2021,” and Atlantic menhaden remain not overfished, with overfishing not occurring .

Lunaas and Macaluso also misrepresented the claim that ASMFC scientists “recommended a 50% cut” in the coastwide menhaden harvest. The ASMFC’s Menhaden Technical Committee and ERP Work Group analysis shows that the Board asked scientists to model a range of catch scenarios and calculate the risk of exceeding the Ecological Reference Point (ERP) target and threshold. A reduction of roughly 50% or more was one modeled scenario, not a singular scientific recommendation. The target is a conservative objective below the threshold that defines overfishing. The Board adopted a 20% reduction for 2026 , projected to have a 0% chance of exceeding the ERP overfishing threshold in 2026 . Calling a 50% reduction simply “what the science said” misstates both the process and the result.

The episode’s “running out of food” premise also omitted a central ASMFC finding: the ERP framework already incorporates predator needs, and even ending all Atlantic menhaden fishing would not, by itself, rebuild striped bass to their biomass target . Sustainable recreational and commercial striped bass fishing mortality remains necessary. Maryland’s newest data further undercut the simple food-shortage narrative: the 2026 juvenile striped bass survey recorded an eighth consecutive year of below-average striped bass reproduction while finding young Atlantic menhaden in abundance and Atlantic silversides at their highest level in more than a decade. Menhaden indices for 2023-2026 were 3.78, 3.66, 2.54 and 2.49; every one exceeded every annual index from 1992 through 2022, and the four-year average was the highest since 1988-1991.

The osprey discussion blurred observation and causation. The 2026 peer-reviewed osprey study found serious reproductive deficits and food stress in higher-salinity areas and identified reduced menhaden availability as a primary driver there, but it did not establish that commercial menhaden harvest caused that reduced availability. USGS is continuing research on the relationship among menhaden availability, osprey reproduction, commercial harvest and environmental conditions. Food stress is not proof of fishery causation.

Macaluso likewise emphasized approximately 140-160 million non-target fish, roughly 30,000 red drum and about 250,000 spotted seatrout without the proportional context. The Louisiana Department of Wildlife and Fisheries reported total bycatch of about 3.6% of catch by weight in the 2024 study. Over 2015-2024, menhaden fishery dead bycatch accounted for 9.9% of red drum fishery removals by weight and 2.7% of spotted seatrout removals, with directed fisheries accounting for the overwhelming majority. Raw totals without those denominators give a distorted picture of the study.

Macaluso also claimed that rebuilding Gulf king mackerel requires leaving 40% more menhaden in the water, while Rowland asserted that tarpon migrating from South Florida to Louisiana “have to have” menhaden. The peer-reviewed Gulf ecosystem model does not support that 40% prescription: its king-mackerel ERP target was 0.964 of 2016 menhaden fishing mortality, and NOAA currently lists the Gulf king mackerel stock as not overfished and not subject to overfishing. The model includes tarpon among many predators of juvenile menhaden, but it does not establish Rowland’s claim that tarpon migrate to Louisiana because food is insufficient off Key West. Newer Gulf diet research likewise found nearshore predators to be generalists using a diverse prey base, with no single menhaden-dependent predator.

Macaluso also called the slower pace of catching the Virginia quota “a pretty clear indication there’s something wrong with that population.” That is not a stock assessment. The ASMFC says its coastwide model cannot determine menhaden stock status within Chesapeake Bay or provide quantitative advice on separate Bay and ocean harvest levels. Those are precisely the questions additional research is intended to answer. Management should establish the problem, connect it to the fishery and show that a proposed restriction would improve the outcome before imposing additional costs on working families.

Rowland should have challenged these claims: whether the 40% revision was an actual population decline; whether 50% was a recommendation or one modeled scenario; what the ASMFC’s striped-bass model says; whether the osprey research established harvest causation; and what Macaluso’s Gulf bycatch figures mean in proportion. He did not. Lunaas and Macaluso are free to advocate for lower quotas, different allocations and additional restrictions, but nobody has the right to mislead the public about what the science says.

Nobody has a more direct stake in healthy Chesapeake Bay, Gulf and Atlantic fisheries than the people whose livelihoods depend on them. UFCW Local 400 has put the fishermen themselves on record ; the NAACP Virginia State Conference has urged Virginia’s governor to protect working families while state-funded science is completed; and the Southern Christian Leadership Conference has warned that these decisions affect African American workers, union families and rural communities. Their future depends on healthy fisheries just as surely as their jobs do. The debate should rest on the complete scientific record, not selective claims presented as settled fact.

Rise of hybrid crabs raises questions for Bering Sea management

October 22, 2026 — A surge in hybrid crabs in the Bering Sea is raising new questions about how federal regulators count crab populations and set harvest limits, according to new Kodiak-based research.

The study, “A Bering Sea marine heatwave triggers unprecedented crab hybridization, challenging fisheries management,” was authored by Erin Fedewa, Emily Ryznar, Connor Cleary and Mike Litzow at NOAA’s Alaska Fisheries Science Center Kodiak Lab, and published Monday in the  Proceedings of the National Academy of Science.

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.”

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.

Guam fishers say shark deterrents fail as disaster aid remains out of reach

August 17, 2026 — Federal fisheries officials heard a familiar complaint from Guam fishers this month: Sharks are stealing their catch, the fixes on the market don’t work, and the island still has no clear path to federal disaster money when storms wipe out their gear.

The Western Pacific Regional Fishery Management Council and the Pacific Islands Fisheries Group hosted a community meeting last week at the Guam Museum Art Cafe, part of a series of gatherings the groups have held across the region to collect input on federal fisheries policy. The Council’s Guam Advisory Panel followed with its own meeting Aug. 8 at the Council office in Hagåtña, taking up commercial fishing rules inside the Marianas Trench Marine National Monument and 2026 strategic planning.

Last week’s gathering was one of close to 40 meetings the fisheries group has held across the Pacific over the past year and a half, part of an ongoing effort to document fisher concerns for the Council and its federal partners. Those observations feed into the Council’s annual Stock Assessment and Fishery Evaluation reports, which Jesse Rosario, the Council’s representative in Guam told The Guam Daily Post help shape recommendations on adapting fishery management to a changing climate. The Council is also building an online and mobile app that will let fishers report shifts in fish abundance, currents and weather directly, with a launch targeted for later this year.

Shark depredation, when sharks strip fish off the line before a catch reaches the boat, ranks among the most pressing issues raised by Guam’s small-boat fishers. According to Rosario, the Council held an international workshop on the problem in February that paired fishers with technology developers and scientists working on deterrent devices.

One Guam fisher put a magnetic deterrent that cost him nearly $70 to the test over two days on the water and came away unconvinced. He described attaching the device near the hook, expecting it to disrupt a shark’s electrical receptors before it reached the bait.

Survey Crashers: Encountering Unexpected New Faces in the Gulf of Maine

August 11, 2026 — The sun was out and the sea conditions were ideal. Fish were being hauled onboard at a consistent rate. I was sampling spiny dogfish on the back deck of the F/V Tenacious II when the captain stopped the hauler and said, “Hey, we caught something different.” I looked up at the hauling station and saw the captain unhooking a chain dogfish, a new species to the Gulf of Maine Bottom Longline Survey . The survey focuses on the rocky bottom habitat in the Gulf of Maine. Every year in the spring and the fall, we partner with two commercial fishing vessels to haul up 45,000 individual hooks from the rocky bottom of the Gulf of Maine from 45 randomly selected locations. We conduct the survey in parallel with the Northeast Bottom Trawl Survey , which samples in the Gulf of Maine during the same time each spring and fall.

Typically we see spiny dogfish, white hake, and haddock along with a variety of other commercially important species. Over the more than 10-year history of this survey, the species caught are typically similar each season. But, occasionally we encounter new species. This spring, during the first trip of the 2026 season, we were excited to encounter a new species.

New species added to our list: the Chain Dogfish

We were fishing in the southeastern corner of the Gulf of Maine on our first leg of the 2026 spring season, when we added the chain dogfish to our list of encountered species. This was the first chain dogfish ever seen in 12 years of the survey. Chain dogfish have a very charismatic pattern on their body, with intricate black lines that stand out sharply against the gray body resembling a tiger.

  • Species: Chain Dogfish (S cyliorhinus retifer )
  • Habitat: Demersal (near the sea floor)
  • Range: Western Atlantic (Massachusetts to Nicaragua)
    • Most abundant off the coast of Virginia and North Carolina in depths between 120 and 2,500 feet.
  • Size: 4 to 24 inches

Another Uncommon Species to the Gulf of Maine: Golden Tilefish

This survey encountered golden tilefish as well, which are also not typically found in the Gulf of Maine. This season, we were fortunate enough to encounter three individuals during the first leg of the spring survey. Like the chain dogfish, our survey typically encounters this species in the southeastern Gulf of Maine. Golden tilefish have a very distinctive coloration and pattern. Golden tilefish are vibrant deep-sea fish sometimes called “clowns of the sea”. They have bright iridescent blue-green backs, scattered spots of yellow and gold, and crisp white bellies. Their heads are rosy-pink and they feature a large, fleshy crest or flap on top. In addition to the vivid coloration, Golden tilefish are considered a delicacy by seafood lovers.

  • Species: Golden tilefish ( Lopholatilus chamaeleonticeps )
  • Habitat: Demersel along the ocean floor along the outer continental shelf and upper slopes
  • Range: Throughout the western Atlantic Ocean from Nova Scotia, Canada, south to northern South America, including the Caribbean and the Gulf of Mexico. In U.S. waters, they are most abundant from Nantucket Island, Massachusetts, down to Cape May, New Jersey, at depths between 250 and 1,500 feet.
  • Size: 10 to 45 inches

Days at sea can be long and the unfavorable weather conditions can make the work difficult, but getting the opportunity to work on a boat in the Gulf of Maine is one of my favorite aspects of this job. At the end of the last haul of this particular trip, after being on deck all day, the sun was beginning to set. The seas were calm and the sky was clear. The sunset over the horizon, turning the sea surface orange while I was finishing data collection and cleaning up the gear was a scene I will never forget.

Being an avid recreational fisherman myself, the ability to collect data that helps contribute information to improve stock assessments and understand fish stocks is very meaningful to me. I also enjoy seeing new and unusual species come aboard during the survey. As ocean conditions change, seeing new species reinforces how essential long-term data collection is to tracking and adapting to the changing Gulf of Maine.

ALASKA: Bill introduced by Alaska’s Murkowski aims to promote use of eDNA analysis in fishery management

August 10, 2026 — Federal fishery managers would start analyzing the DNA collected in ocean waters to help inform their decisions, under a bipartisan bill introduced in the U.S. Senate, Alaska’s Republican U.S. Sen. Lisa Murkowski said on Thursday.

Called the Fisheries Science Modernization Act, the bill would set up a system for the use of environmental DNA, known as eDNA, in fishery management. The bill would establish a National Oceanic and Atmospheric Administration pilot program using eDNA to assess fishery stocks, require NOAA to develop an agency-wide eDNA implementation plan and direct the agency to routinely collect eDNA samples and integrate that form of surveillance into its fisheries research and ecosystem monitoring.

Along with Murkowski, Sen. Sheldon Whitehouse, D-Rhode Island, is a prime sponsor of the measure. Cosponsors are Sens. Dan Sullivan, R-Alaska; Jeff Merkley. D-Oregon; Chris Van Hollen, D-Maryland; Patty Murray, D-Washington; Angus King, I-Maine; and Adam Schiff, D-California.

US bill would increase use of eDNA in fisheries management

August 10, 2026 — U.S. lawmakers have introduced a bill to increase the use of environmental DNA (eDNA) in fisheries surveys and management, claiming the technology is a low-cost tool that can better help the government assess fish populations.

“Without accurate stock assessments, we cannot make the informed, science-based management decisions needed to ensure our fisheries remain sustainable for generations to come,” U.S. Senator Lisa Murkowski (R-Alaska) said in a release. “Environmental DNA is an innovative, cost-effective tool that will give our scientists a clearer picture of our fisheries while expanding survey coverage and reducing costs. This legislation is the product of extensive collaboration with NOAA, Alaska fishermen, Tribal partners, academia, and industry to modernize how we assess fish stocks using the best available science.”
