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.”

Study offers hope for the resilience of the American lobster fishery

September 11, 2024 — According to a study by researchers at William & Mary’s Batten School of Coastal & Marine Sciences, the American lobster may be more resilient to the effects of climate change than expected. For the first time, experiments performed at the Virginia Institute of Marine Science (VIMS) have documented how female American lobsters groom their offspring, providing evidence that these behaviors are not significantly impacted by temperature and acidity levels forecasted for Maine’s coastal waters by the end of the century.

The findings are published in the journal Marine Ecology Progress Series.

Despite being one of the largest commercial fisheries in the U.S. with an annual economic impact of more than $460 million in Maine alone, few studies have documented the reproductive  of female American lobsters. With the Gulf of Maine warming faster than nearly any other ocean surface on the planet, it’s important to understand how the effects of climate change will impact the sustainability of the species and the fishery it supports.

“Brood grooming by female lobsters has been anecdotally observed, but it had not been quantitatively recorded before,” said Abigail Sisti, who is completing her Ph.D. in Marine Science at the Batten School and is lead author on the study. “In other crustaceans, these behaviors can have a significant impact on the survival of their offspring. Because the environment supporting the lobster fishery is rapidly changing, we wanted to understand how it might impact the way they care for their offspring.”

Female American lobsters can produce thousands of eggs that they hold under their tails for long periods of time, between five to 12 months, as the embryos develop. In other crustaceans, grooming behaviors help clear out parasites, remove dead eggs and facilitate the flow of water carrying oxygen and nutrients through the densely packed egg masses.

The study was part of a larger effort to determine how multiple stressors affect the reproductive success of the species. In this study, the researchers were testing whether increases in  and acidity had an impact on grooming behaviors and embryo survival.
