In the waters of the Chesapeake Bay, an unwelcome visitor has been making itself at home. The blue catfish, a species native to the Midwest, was introduced to Virginia rivers in the 1970s for recreational fishing. But it didn't stay put. Now, it's eating everything in sight—blue crabs, native fish, and more—threatening the bay's ecological balance and the region's $1 million crab industry.
To combat this, schools across Maryland and Virginia are putting blue catfish on the lunch menu. It's a creative solution that turns students into predators of an invasive species, helping to curb its rapid overpopulation. The initiative, backed by the USDA, offers a mild-flavored white meat patty that's both nutritious and environmentally friendly.
Turning a threat into a meal
The idea started in Caroline County on Maryland's Eastern Shore, where food service supervisor Beth Brewster saw an opportunity. She connected with the Maryland Department of Agriculture and, with the help of program manager Karen Fedor, developed child-friendly recipes that meet federal dietary standards. After pandemic-related delays, the project joined forces with Bay2Tray, a California-based program run by Real Good Fish. Now, processing facilities across the region are preparing catfish patties inspired by traditional crab cakes, and they've even reached university cafeterias as far away as Texas.
Students are on board. Raelynn Truitt, a 5th grader at Preston Elementary School near the Choptank River, says the patties taste delicious. It's a win-win: kids get a healthy meal, and the environment gets a helping hand.
A growing problem
The blue catfish population has exploded in recent years. Originally, officials thought brackish waters would keep them contained, but historic flooding in 2018 pushed fresh water into the bay, allowing the fish to colonize new habitats. These massive fish can exceed 100 pounds and devour juvenile blue crabs, flounder, and menhaden across the 300-kilometer estuary, which is home to more than 3,600 species.
Branson Williams, director of the Invasive Species Program at the Maryland Department of Natural Resources, confirms that the species easily tolerates varying salinity levels. With no natural predators, human harvest is the primary control method.
Commercial watermen like Rocky Rice, a fourth-generation fisherman, have shifted their focus from crabs to catfish. Rice runs hoop nets on the lower Potomac River three days a week, bringing in 1,200 to 1,500 pounds per trip. The year-round fishing and lack of size limits make it an attractive alternative. However, there's a logistical hurdle: blue catfish is the only wild-caught fish in the U.S. that requires mandatory USDA inspection, a rule designed to protect against cheap imports. This limits processing to just four certified plants in Maryland, creating a bottleneck.
Similar battles nationwide
This isn't just a Chesapeake Bay problem. Kentucky and Illinois are promoting the consumption of invasive Asian carp in the Great Lakes, while Maine and Washington are fighting green crab invasions. The approach is the same: eat them to beat them.
Research from the University of Maryland and the Virginia Institute of Marine Science confirms that standard-sized catfish (15 to 36 inches) have contaminant levels well below FDA safety thresholds. Health officials do advise trimming belly fat from larger, older fish, but for the most part, these catfish are safe and healthy to eat.
A sustainable solution
The Bay2Tray program connects watermen with schools, supplying whole-grain breaded blue catfish portions. The "catty patty" is made from pure white meat, processed under strict USDA guidelines, and offers a high-protein dish without any fishy aftertaste.
While complete eradication of the blue catfish is biologically impossible, heavy annual harvests through institutional sales represent the most effective long-term defense. It preserves native biodiversity, supports local fishing economies, and keeps this invasive predator in check—one school lunch at a time.
