Judge rules NOAA must release bycatch photos from trawlers

November 4, 2025 — A federal judge in California has ordered NOAA to release photos, videos and other visual data documenting the catch of nontargeted species by the state’s halibut trawl fishery.

In a ruling, Judge Josephine Staton of the U.S. District Court for the Central District of California told NOAA to release 77 photographs to the environmental group Oceana detailing the bycatch of fish and marine mammals caught up in nets used by bottom trawlers off the California coast.

Oceana had requested the photos in 2022 under a public records request, but NOAA declined to provide them, citing an exemption where the release of documents violates nondisclosure provisions in federal law. NOAA argued that the Magnuson-Stevens Fishery Conservation and Management Act prohibited the release of the photos because doing so could identify the identities of fisheries observers whose identities were to be kept private.

NORTH CAROLINA: A 38-year research project in Pamlico Sound ends with fisheries boat breakdown

August 27, 2025 — Nearly four decades of research ended this year because a dwindling budget in the state Division of Marine Fisheries left its research boat out of commission.

Scientists have trawled the Pamlico Sound netting fish and crustaceans since 1987.

But the boat, named the Carolina Coast, won’t go out in 2025.

“This is the end of the data set. There’s nothing we can do about that. It’s over,” said Kathy Rawls, who directs the Division of Marine Fisheries.

Rawls broke the news about the rotting and leaking 41-year-old boat last week to the Marine Fisheries Commission, a policy-setting board appointed by the governor.

“We lack the resources to repair or replace the vessel,” she said. “As you can imagine, that is a huge blow.”

Doug Rader, an oceans scientist serving on the commission, said the news is “close to catastrophic.”

NORTH CAROLINA: Shrimp trawling ban in NC sounds dies in the state House, Republicans say

June 25, 2025 — North Carolina House Republicans won’t take up a bill that would ban shrimp trawling in North Carolina sounds, they said Wednesday — a decision met with jubilation from shrimpers in the Legislative Building.

Republican Rep. Mitchell Setzer, the House speaker pro tempore, confirmed the decision with The News & Observer.

House Bill 442 was revised early last week to include an amendment banning trawling within a half-mile of the coast. Before the amendment, the bill originally sought to expand fishing seasons for flounder and red snapper.

New trawl net to cut costs and boost survey accuracy

May 29, 2025 — A collaborative sea trial aboard NOAA’s vessel Bell M. Shimada has set the stage for a more efficient and cost-effective approach to fishery surveys on the West Coast.

Fishing industry leaders joined NOAA Fisheries scientists in testing an innovative new trawl net designed to gather more accurate data in less time and at lower cost.

Developed in partnership with industry experts, the Multi-Function Trawl (MFT) net is engineered to combine two separate West Coast fisheries surveys that had previously relied on different nets. The Adjustable design allows a single vessel to “more safely gather more data in less time and at lower cost,” according to NOAA.

“The new trawl, which uses the same design features and technologies used by many fishermen, increases our confidence in the survey results,” Greg Shaughnessy, chief operating officer at Ocean Gold Seafoods in Westport, Washington, said. Shaughnessy, a long-time industry collaborator, became interested in the survey process after observing the sudden decline of sardines off the Northwest Coast in 2015. “I needed to understand how these surveys work,” he recalled. “You have to have the best available science to get the management right.”

OPINION: Safeguarding Alaska offshore habitat and providing a path forward for trawling

September 27, 2024 — As commissioner of the Alaska Department of Fish and Game, I often hear concerns about the impacts of trawl gear used in Alaska’s pollock fisheries, most recently related to potential unobserved mortality of crabs and halibut in the Bering Sea. We know that pelagic trawls fishing for Alaska pollock are often operated close to, or in contact with, the seafloor. What we do not know is the extent of this contact or the potential impacts on bottom-dwelling species like crab and halibut and their habitat. These data gaps are concerning to Alaskans, and I want to highlight actions underway to understand and address the unintended consequences on seafloor ecosystems in areas that fishery managers and stakeholders have recognized as needing protection.

Alaska’s marine fisheries are universally recognized as a shining example of both bounty and sustainability. About 60% of domestically caught U.S. seafood comes from Alaska. Science-based management by the Alaska Department of Fish and Game, North Pacific Fishery Management Council, and NOAA’s National Marine Fisheries Service (NMFS) has proven to be the key to ensuring that Alaska’s fisheries continue to support good jobs, vibrant fishing communities and a healthy food supply for generations to come. But fishery management must be adaptive to changing biological and economic conditions, and declines in crab, halibut and other important stocks in recent years have heightened concerns about the impacts of bottom trawling.

When considering trawl fisheries, it’s important to distinguish between bottom trawls and pelagic trawls used in the pollock fishery. As the name implies, bottom trawls are specifically designed to catch fish at or near the seafloor. Pelagic trawls are designed to fish higher than bottom trawls and are typically used to target a single species. The best available information indicates that bottom trawls have a greater impact on seafloor habitat than pelagic trawls, and ADF&G, the Council and NMFS have closed large areas of the ocean off Alaska to bottom trawling to minimize these impacts. That said, some key species such as scallops can only be fished with bottom fishing gear.

CT innovator IDs illegal trawlers with AI and ears in the ocean

August 14, 2023 — With millions of dollars from venture capital investors, a Connecticut startup that emerged from the submarine industry is using artificial intelligence to pioneer new underwater technology, from tracking illegal fishing to protecting whales during construction of offshore wind farms.

Miles off the U.S. coast, Groton-based ThayerMahan is readying a nautical network of buoys and roaming sea drones to ID commercial fishing trawlers that may be operating illegally, whether in U.S. territorial waters or those of other nations where catch limits are abused routinely to put pressure on fish stocks.

Closer to home in partnership with Hydrotechnik-Luebeck based in Germany, ThayerMahan is assisting offshore wind developers with a system to “bubble wrap” wind turbine monopiles with curtains of sound-absorbing bubbles, in an effort to minimize disruptions for whales and other marine life. ThayerMahan is tracking whale positions to determine if any are swimming too close to turbine construction sites and is helping wind farm developers comply with federal environmental rules.

Mike Connor retired as a vice admiral overseeing the U.S. Navy’s submarine fleet to start ThayerMahan in 2016, seeing the need for a startup that could develop a networked system of underwater sensors to help the Navy identify vessels. Connor named the company for the naval power theorist Alfred Thayer Mahan, who was a major influence in the global naval buildup preceding World War I.

Op-ed: What science says about the sustainability of trawling

September 26, 2022 — Ray Hilborn is a professor in School of Aquatic and Fishery Sciences at the University of Washington.

With the launch of several recent advocacy campaigns, bottom-trawling is squarely in the crosshairs of some environmental groups and media outlets that regurgitate their press releases.

There is no question that bottom-trawling has environmental impacts, as all food production does, but there is misinformation floating around about the true impact of bottom-trawling, especially in comparison to other types of fishing and food production. With campaigns like #BanBottomTrawling growing, I want to look at what the science says about the sustainability of bottom-trawling.

URI professor part of a worldwide study on impacts of bottom trawling on health of seabeds

January 10, 2021 — A worldwide study on the impacts of bottom trawling, which accounts for a quarter of the world’s seafood harvest and can negatively affect marine ecosystems, has found that seabeds are in good health where trawl fisheries are sustainably managed.

The research published in Proceedings of the National Academy of Science (PNAS) by a team including co-author Jeremy Collie, Professor of Oceanography at the University of Rhode Island, builds on recent international collaboration in this field and is the first worldwide study of its kind. It brings together data from 24 large marine regions around the world to establish a relationship between distribution and intensity of trawling activities and the biological state of seabeds.

Finders keepers: New trawl technology helps fleets fish smarter and managers track biomass, despite covid disruptions

September 15, 2020 — In trawl fisheries, vessels usually spend costly amounts of time and fuel searching for fish. Even with advanced technology, the cost of finding fish comes with the price of investment. To increase efficiency, Kongsberg Maritime of Norway has developed an unmanned surface vehicle that can hunt for fish at a fraction of the cost of a fully manned fishing vessel.

“The vessel is equipped with high-definition SX95 omnidirectional sonar,” says Richard Mills, head of marine robotics sales at Kongsberg. “Then there is a moon pool in which we can put other equipment. We just put an EK80 echosounder in one for a company we can’t name, and we are hoping to demonstrate it next year for NOAA.” According to Mills, the USV can search large expanses of ocean and transmit data to land-based receivers and fishing vessels. “We sit down with our customers and look at cost benefits,” says Mills, noting that the USV could operate for as little as 15 percent of a manned vessel’s crew costs and fuel costs.

The 26.5-foot USV has a 7.3-foot beam and draws 2.3 feet. For receiving commands and transmitting data, the vessel has a mast that reaches 14.4 feet above the sea surface. The vessel can run autonomously or be operated from a laptop PC or radio control with data telemetry via a Kongsberg’s K-MATE control system, with communication through Maritime Broadband Radio and Iridium satellite (VSAT optional).

Witch Flounder Trimester Total Allowable Catch Area Closed to Common Pool Vessels Fishing with Trawl Gear

April 12, 2019 — The following was released by NOAA Fisheries:

Effective at 0845 hours on April 12, 2019, statistical areas 512, 513, 514, 515, 521, 522, and 525 are closed for the remainder of Trimester 3, through April 30, 2019. During this closure, common pool vessels fishing with trawl gear may not fish for, harvest, land, or possess regulated multispecies in or from this area. The closure is required because 90 percent of the Trimester 3 Total Allowable Catch (TAC) for witch flounder is projected to have been caught. This area will reopen at the beginning of fishing year 2019, at 0001 hours, May 1, 2019.

If you have crossed the vessel monitoring system demarcation line and are currently at sea on a groundfish trip, you may complete your trip in all or part of the closed areas.

For more information read the rule as filed in the Federal Register or the bulletin as posted on our website.
