National TRAP Program targets ghostly issue with second round of coastal clean up funding

November 3, 2025 — Lurking in the waters along our shorelines, a haunting presence is luring marine life to their untimely demise and trapping their spirits in an underwater purgatory. This isn’t the plot of a new Halloween blockbuster, it’s the unfortunate impact of derelict fishing equipment commonly known as “ghost traps.”

William & Mary’s Batten School of Coastal & Marine Sciences & VIMS has awarded $1.8 million to 13 organizations throughout the U.S. focused on the removal of derelict fishing gear, which poses a significant threat to the sustainability of coastal and marine environments and the fishing industries from which they originate. This is the second year of subawards distributed through the National Fishing Trap Removal, Assessment and Prevention (TRAP) Program.

A scientific solution for a ghoulish problem

In the United States, commercial trap fisheries generate over $1 billion in annual revenue from seafood sales, referred to as landings. Each year, traps are lost due to vessel-gear interactions, storms and gear degradation. These “ghost traps” become inaccessible to fishermen but continue to function, resulting in mortality of both target and non-target species, habitat damage and reduced fishery landings. A 2016 report found that removing just 10% of derelict crab pots and lobster traps could result in an additional $831 million in global landings annually.

In 2023, the Batten School & VIMS was the recipient of an $8 million, four-year grant from the National Oceanic and Atmospheric Administration’s (NOAA) Marine Debris Program to administer the National TRAP Program. In addition to distributing approximately $1.5 million annually to fund regional cleanup efforts, the program has established a standardized national database to evaluate the environmental and economic benefits of the removal efforts and to inform future policies.

In its first year of funding, the TRAP Program awarded over $1.4 million to fund 11 projects. So far, the efforts have resulted in the removal of over 7,000 derelict traps totaling more than 300,000 pounds of debris. A number of projects are still recovering derelict traps, and removals in Louisiana are set to begin in February. Many other regional success stories have surfaced from these efforts.

“We are thrilled with the initial results from our inaugural TRAP Program recipients. Their success is a testament to the impact that locally-designed solutions can have on global issues,” said Kirk Havens, director of the Batten School & VIMS Center for Coastal Resources Management, which administers the TRAP Program under the direction of co-principal investigators Professor Donna Bilkovic and Associate Professor Andrew Scheld. “Our second round of recipients have demonstrated that same creativity, thoughtfulness and local community engagement in their project proposals, and we are proud to support them as they work for the benefit of their communities and marine ecosystems.”

VIRGINIA: VA Wetlands and Living Shorelines Worth $90 Million in Economic Value

September 9, 2025 — A push in Virginia to invest in shorelines and marshes may be paying off. Natural wetlands and man-made living shorelines around Virginia’s Middle Peninsula generate just under $90 million of economic value each year, according to a new study led by William & Mary’s Batten School & VIMS.

The Middle Peninsula (Gloucester, Mathews, & Middlesex counties) has been a Habitat Focus Area of the National Oceanic and Atmospheric Administration’s Chesapeake Bay Office (NCBO) since 2022. That Office funded the study, which combines ecological data, spatial modeling, economic valuation, and surveys to assess the current and predicted benefits of marsh ecosystems. Researchers used numbers from the study to develop a new online tool for coastal communities to estimate the economic benefits of marsh and living shoreline projects. It’s known as SHORE-BET (Shoreline Benefit Estimation Tool).

“This study looks at wetlands from a number of perspectives and puts research-informed values on the benefits they provide,” said Donna Bilkovic, professor and assistant director of the Center for Coastal Resources Management at the Batten School & VIMS. “These data serve as the foundation for SHORE-BET, allowing local planners and individual landowners to better understand the potential environmental and economic benefits associated with living shoreline projects and marsh protection and restoration.”

VIMS To Lead Abandoned Crab Pot Program, Awarded Largest Grant In Its History

April 26, 2023 — NOAA Fisheries tapped William & Mary’s Virginia Institute of Marine Science (VIMS) to lead a new nationwide program to reduce “ghost fishing” by derelict crab and lobster pots abandoned or lost to storms and vessel entanglements. The new role comes with a record $8 million grant for VIMS to administer the program.

This Trap Removal, Assessment & Prevention (TRAP) program will include partner institutions, commercial fishermen, and interested Native tribes in the Pacific Northwest and along the Atlantic coast from Florida to the Gulf of Maine. The TRAP program will initially focus on the gear used to catch crabs (blue, Dungeness, and stone) and lobsters (American and spiny). Federal funding for the program overall is $8 million over four years, distributed by the VIMS Center for Coastal Resources Management (CCRM) through a competitive grant program.

‘Astounding’ amount of fishing gear lost in ocean each year

October 13, 2022 — It’s known as “ghost gear.” Abandoned traps, aimlessly drifting nets, and other lost fishing equipment can haunt the ocean for years, ensnarling and killing whales, turtles, and other marine creatures. The magnitude of the problem has been hard to quantify, but a new study provides the first solid global estimate of the amount of equipment lost each year: enough nets to cover Scotland, for example, and fishing line that could wrap around the equator 400 times.

These losses have been “a cryptic issue that’s been out of sight, out of mind,” says marine scientist Kirk Havens of the Virginia Institute of Marine Science (VIMS), who was not involved in the study. Lost traps and nets are “going to capture and kill things,” he adds. “That’s what they’re made for.”

The comprehensive new findings, researchers say, could help both conservation and fishing organizations track their progress toward protecting the seas from lost gear.

Kelsey Richardson, a marine and social scientist, first grasped the enormity of lost fishing gear while working in the Pacific Islands region for an intergovernmental organization. The regulators in charge of fishing there required vessels to host observers, who recorded losses of fishing gear. The data and findings were unique—and concerning because they showed how frequently boats at sea lost hooks, fishing lines, ropes, and nets.

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.

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.

New Acoustic Survey Will Investigate Previously Uncounted Menhaden

January 12, 2022 — The following was released by the Science Center for Marine Fisheries:

Despite being one of the largest and most high-profile fisheries on the East Coast, there are still gaps in our understanding of Atlantic menhaden. This is especially true in their northern range, in New England and the Mid-Atlantic. But this winter, a new project will look specifically to count menhaden in these areas, shedding new light on an important but underexamined portion of this species.

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, is about to launch a winter population survey of menhaden, specifically of menhaden spending the season off the coast of New Jersey. The area is home to a growing winter bait fishery, but because there have been few attempts to survey menhaden this far north, there is currently not a good count of how many menhaden are in the area, as well a lack of good data on measurements like age and weight compositions.

“Right now, having a full picture of menhaden is limited by the lack of available information on the northern part of the stock,” said Dr. Genny Nesslage, a professor at UMCES and one of the lead researchers on the project. “Surveying this part of the population will hopefully give regulators the data they need to make informed decisions on how to manage menhaden coastwide.”

Atlantic menhaden are a coastwide species, with a range spanning from Maine to Florida. But most of our knowledge of the stock comes from data collected from purse seine fisheries in the Mid-Atlantic and around the Chesapeake Bay. Because older, larger menhaden are more likely to be found in northern waters, an entire segment of the menhaden population is not fully counted by current data collection methods.

As it is increasingly clear that there are significant numbers in this northern portion of the menhaden stock, surveys like these will be important in providing a fuller picture of the population, benefitting both the regional bait fishery and other, existing menhaden fisheries.

“Getting a better count of menhaden in the north is critical in improving our understanding of the fishery coastwide, and validating the population estimates that come from our current assessment models,” said Dr. Nesslage. “The more diverse sources of data we have on menhaden, the more confident we can be in our decisions on how to manage it.”

The survey was funded by the NOAA Fisheries Saltonstall-Kennedy Competitive Grants Program and its design was funded by a grant from the Science Center for Marine Fisheries (SCEMFIS), which connects marine scientists with members of the fishing industry to fund needed research for finfish and shellfish.

Researchers map best conditions for forage fishes in the Chesapeake

October 28, 2021 — Big fish eat smaller fish, but only if there are smaller fish to eat. A new study led by researchers at William & Mary’s Virginia Institute of Marine Science maps the conditions most suitable for key species of forage fishes in the Chesapeake Bay, offering guidance for any future efforts to protect or restore the habitat required to yield sufficient prey for predatory fishes such as striped bass.

Lead author on the study, which appears in the October issue of Frontiers in Marine Science, is Dr. Mary Fabrizio, a professor and chair of Fisheries Science at VIMS. Co-authors are fellow VIMS researcher Dr. Troy Tuckey, along with Drs. Aaron Bever and Michael MacWilliams of Anchor QEA, LLC. Bever is a VIMS alum.

“Small fishes such as bay anchovy are important components of the diets of predatory fishes in Chesapeake Bay,” says Fabrizio, “but factors that affect local abundances of these forage fish have been largely unexplored.”

To throw light on these factors, the research team set out to quantify and map suitable habitats for four common species of forage fishes in Bay waters, and to assess the relationship between habitat extent and fish abundance. In addition to bay anchovy, the forage species studied were juvenile spot, juvenile spotted hake, and juvenile weakfish.

The team based their study on data generated by counting the number of forage fishes caught in a trawl net during fishery surveys conducted by VIMS and the Maryland Department of Natural Resources between 2000 and 2016. These surveys sample at more than 100 sites throughout the Bay each month. They coupled these catch data with output from computer models simulating the environmental conditions at each sampling site. These conditions include water depth and temperature, salinity, stratification, dissolved-oxygen levels, and current speeds. The researchers also noted whether the bay floor beneath each net tow was sandy or muddy, and the distance to the nearest shoreline.

Virginia’s striped bass forecast looks stable as juvenile numbers hold steady

October 20, 2021 — Juvenile striped bass numbers are holding steady in Virginia’s Chesapeake Bay tributaries, the latest annual survey by the Virginia Institute of Marine Science found.

But a parallel survey in Maryland waters showed below-average numbers.

The surveys look at striped bass that hatched in the spring and that will be large enough to catch, legally, in three to four years.

Preliminary results of the Virginia survey showed an average of 6.3 fish for each haul of a seine net in the James, York and Rappahannock rivers. These young striped bass usually measure between 1.5 and 4 inches. That’s the 9th consecutive year of average or above average results, VIMS said.

Close Quarters: Ocean zoning pushes fisheries to the brink

September 23, 2021 — The following is an excerpt from an article published in National Fisherman by Dr. Roger Mann, professor of Marine Science at the College of William and Mary’s Virginia Institute of Marine Science. It is based on an article published by the Journal of Shellfish Research. That paper, “An Ecosystem is Not a Monument, and Other Challenges to Fishing in the 21st Century,” is based on a talk given by Dr. Mann at the annual meeting of the National Shellfisheries Association.

Managing fisheries is no longer simply about [the Magnuson Stevens Act’s] directives to “conserve and manage” a sustainable resource to serve the “social and economic needs of the States.” It is about managing fisheries in a changing landscape of competition for ocean resources, where the environment is changing faster than in living history, and species footprints are on the move.

Part of this changing landscape is the creation of large, no-take MPAs, like the Northeast Canyons and Seamounts Monument off the coast of Cape Cod. Designated by President Obama with the sweep of a pen using the Antiquities Act of 1906, the 4,913 square miles of the monument are now managed by multiple federal agencies under a bewildering patchwork of legislation, including Magnuson, the Endangered Species Act, the Marine Mammal Protection Act, the National Wildlife Refuge System Administration Act, the Refuge Recreation Act, Public Law 98-532, and Executive Order 6166. Then there is the National Marine Sanctuaries Act, through which the government can designate and protect marine areas of national significance.

This plethora of confusing legislation lacks uniform definitions. It is not clear on how — or even if — MPA designations are required to be revisited, even when species move. In addition, it does not state who has precedent over whom in the management hierarchy.

Even as questions remain over existing MPAs, activists are pushing for more with a “30×30” campaign to protect 30 percent of our nation’s land, inland waters and oceans as conservation areas by 2030. But what is “protected” in this context? Is a region protected only by excluding fishermen through a no-take MPA? Or does the Magnuson Act directive to “conserve and manage the fishery resources” and “exercise sound judgment in [their] stewardship” rise to the level of protection? If so, then is not the entire exclusive economic zone already protected?

MPAs are far from the only competition fishermen are facing in the ocean. Environmental advocacy, communications corridors, mining, national defense, and shipping all threaten fishermen’s access to ocean resources. Perhaps the biggest incursion of all is offshore wind development: the U.S. East Coast continental shelf already has 1.7 million acres of federal bottom under lease for offshore wind, with the Biden administration seemingly poised to expand such efforts along the Atlantic, Pacific and Gulf coasts. Offshore wind projects have a projected lifespan of 50 years, with turbine spacing restricting access for both commercial fishing vessels towing mobile gear and federal survey vessels. Stock assessment surveys will be compromised, resulting in reduced quotas for fishermen.

With so many competitors muscling their way into the ocean, who will be the winners and losers? Over what time frames will winners emerge? Where does preservation of the fishing industry sit in the pecking order? At the bottom?

The “space” for fisheries is shrinking. Commercial fishing won’t be the largest economic player as development of our oceans continues, but it is historically an important part of the economic and social structure of coastal communities. Fisheries are based on moving species distributions that do not function well within fixed boundaries, like those being zoned for MPAs and offshore wind.

Study finds existing forage fish management is working

July 9, 2021 — Efforts to ratchet down fishing effort on species like herring and menhaden in the name of “extra precautionary management” in most cases are unlikely to bring additional benefits for stocks of predator species that eat them, according to a new study.

“Our results indicate that predator productivity was rarely influenced by the abundance of their forage fish prey,” wrote authors Christopher Free of the University of California-Santa Barbara, Olaf Jensen of the University of Wisconsin-Madison, Ray Hilborn of the University of Washington. “Only 6 predator populations (13 percent of the total) were positively influenced by increasing prey abundance and the model exhibited high power to detect prey influences when they existed,” according to their paper titled “Evaluating impacts of forage fish abundance on marine predators,” originally published in the journal Conservation Biology.

“These results suggest that additional limitation of forage fish harvest to levels well below sustainable yields would rarely result in detectable increases in marine predator populations.”

The findings were released July 6 through the Science Center for Marine Fisheries, a cooperative effort to improve sustainability of fisheries and reduce uncertainty in biomass estimates with work by university partners led with the University of Southern Mississippi Virginia Institute of Marine Science, College of William and Mary, as academic sites.

“Our work suggests that the sustainable limits that we already employ are sufficient for maintaining forage fish abundance above the thresholds that are necessary for their predators,” Free of UC Santa Barbara in a statement describing the findings. “Predators are highly mobile, they have high diet flexibility, and they can go and look for forage fish in places where they’re doing well, switch species for species that are doing well, and have often evolved to breed in places where there’s high and stable forage fish abundance.”
