Across the United States, a growing movement is encouraging Americans to help solve an environmental crisis through their dinner plates. Known as invasivorism, this approach transforms destructive invasive species into menu items. Instead of relying solely on costly removal programs and chemical controls, experts are asking a simple question: What if we ate the problem?
Invasive plants and animals wreak havoc on ecosystems nationwide. They crowd out native species, damage habitats, and disrupt natural balance. Traditional management methods have proven expensive and often ineffective. Wildlife officials estimate invasive species cost the United States economy more than $26 billion annually through crop losses, habitat destruction, and impacts on native wildlife populations.
But chefs, scientists, and local communities are testing a different strategy. By creating demand for invasive species as food, they hope to make removal part of everyday life. Conservation biologist Joe Roman, who started the Eat the Invaders project, emphasizes the appeal. “This is not Fear Factor,” he told National Wildlife magazine. “You want something tasty.”
Success Stories from the Sea
One standout example is the lionfish, a striking reef predator that has devastated ecosystems throughout the Caribbean and Gulf of Mexico. With few natural predators and voracious appetites, lionfish can eliminate native fish populations within years. Florida responded by turning the invader into a culinary attraction, hosting events like Lionfish Restaurant Week to promote the white, flaky fish.
The campaign has shown real results. Since 2015, the Florida Fish and Wildlife Conservation Commission’s annual Lionfish Challenge has removed more than 165,000 lionfish from local waters. Divers, fisheries biologists, and restaurants worked together to make lionfish a sought-after menu item. The fish now appears in tacos, fritters, and sushi rolls across Florida, Georgia, South Carolina, and Puerto Rico.
Other edible invaders are following similar paths. Hawaii’s Ta’ape fish is appearing on seafood menus. Asian shore crabs have found their way into upscale sushi preparations. European green crabs are being transformed into bouillabaisse, bisques, and croquettes across New England restaurants. These campaigns demonstrate how consumer appetite can become a conservation tool when properly channeled.
Rodents on the Menu
During National Invasive Species Awareness Week this February, wildlife officials made an unusual recommendation: consider eating nutria. These South American rodents, introduced for the fur trade, have established populations in 18 states. Resembling small beavers, they can grow up to 40 inches long and consume a quarter of their body weight in vegetation daily.
The damage nutria cause is severe. Their eating habits destroy native plants and destabilize soil, leading to erosion and habitat loss for threatened species. California’s Department of Fish and Wildlife has removed approximately 5,500 nutria since detecting a population spike in 2017. Officials describe the meat as tasting similar to rabbit or dark turkey, with recipes for stews and chili available online.
Wildlife experts stress that eating invasive species should supplement, not replace, other conservation efforts. Erin Huggins from the United States Fish and Wildlife Service explained that consuming invasives can help protect native wildlife by reducing their numbers and limiting ecosystem damage. However, she noted this approach must combine with traditional conservation methods for effective control.
The Supply Chain Challenge
Despite growing enthusiasm, transforming invasive species into mainstream food products faces significant logistical hurdles. The infrastructure that makes conventional seafood affordable simply doesn’t exist for most invasive species. Individual divers catching lionfish face expensive barriers like commercial wholesale licenses costing thousands of dollars statewide, making little economic sense when average catches remain modest.
Processing facilities present another obstacle. Established seafood processors typically refuse small deliveries, preferring bulk orders from commercial operations. A diver catching 30 pounds of lionfish faces frustration in finding anyone willing to accept such a small quantity. Distance compounds the problem, as many processors operate far from coastal harvesting sites, making transportation impractical for limited catches.
Government regulations designed to protect food safety add complexity. Feral pigs must be trapped alive and transported to licensed facilities for slaughter and processing before restaurants can legally sell the meat. This requirement transforms what could be straightforward hunting into a logistical puzzle requiring coordination between trappers, transporters, and licensed processors.
Chefs Leading the Charge
At the forefront of the invasivorism movement stand innovative chefs who see invasive species not as pests but as premium ingredients. Jesse Griffiths of Dai Due in Austin built a nationally recognized restaurant around feral pigs. His establishment uses only locally sourced ingredients, with wild boar appearing regularly. USA Today named Dai Due a Restaurant of the Year in 2025.
Despite success, Griffiths candidly acknowledges challenges. Feral pig meat costs roughly three to four times more than conventional pork due to hunting and processing labor. Yet he sees value beyond profits. Industrial pig farming requires massive land and energy inputs, along with ecosystem-damaging fertilizers and pesticides. “Every pound of feral hog replaces a pound of meat from an otherwise broken food system,” Griffiths explained.
Bun Lai of Miya’s Sushi in New Haven, Connecticut, takes invasivorism differently. The James Beard Award nominee transformed his restaurant into what many consider the world’s first sustainable sushi establishment. His menu prominently features Asian shore crabs collected during low tide. The crabs are deep-fried whole, seasoned, then served on ocean rocks sculpted to resemble their native habitat.
Beyond the Dinner Plate
While human consumption generates headlines, innovators are discovering that invasive species can serve markets extending far beyond restaurant menus. These alternative applications offer scalability advantages that food service alone cannot match, potentially creating economic incentives needed to drive meaningful population reductions. Pet food represents one particularly promising frontier for large-scale invasive species utilization.
Julia Kurnik of the World Wildlife Fund’s Markets Institute has been researching partnerships between fishermen and pet food manufacturers to create sustainable dog food from Asian carp. Americans spend more than $50 billion annually on pet food, creating a massive potential market for invasive species. Companies like Arch Pet Food and Chippin have begun incorporating Asian carp into formulations.
The bony structure making Asian carp challenging for human consumption actually works well in pet food manufacturing. Processing facilities can grind whole fish into meal or create protein concentrates for kibble. This utilization of entire animals improves economics while reducing waste. Importantly, the volume pet food manufacturers can process dwarfs what restaurants could consume, potentially making serious dents in invasive populations.
Federal and State Support
Recent government initiatives show promise in addressing barriers to invasive species markets. The USDA announced $6 million in grants for seafood processors to expand capacity for handling invasive wild-caught catfish, with individual projects eligible for up to $1 million. Additionally, a pilot program committed $2 million to purchasing Chesapeake Bay blue catfish, supporting regional processors while providing protein to food banks.
Some states are removing regulatory obstacles. Connecticut passed legislation allowing fishermen to harvest invasive species for restaurant use without special permits, directly eliminating one bureaucratic barrier that previously discouraged participation. State Representative Aundré Bumgardner, who worked on the legislation, sees broader impact. “By turning these crabs from a threat into a resource, the law helps protect our waters,” he noted.
These policy changes demonstrate government recognition that reducing administrative hurdles can accelerate invasive species removal while creating economic opportunities for fishing communities. Federal funding helps build the processing infrastructure that makes commercial viability possible. Combined with state-level permit reforms, these initiatives create conditions where invasivorism can scale beyond isolated chef-driven projects into sustainable regional industries.
A Practical Conservation Tool
Scientists acknowledge that eating alone cannot eliminate invasive species entirely. Complete eradication remains unrealistic given reproduction rates and the difficulty of finding every individual. Instead, experts embrace functional eradication, which focuses on suppressing populations to levels where their harm becomes manageable rather than eliminating them completely.
Research supports this more modest goal. Reducing invasive populations can provide meaningful relief for native species struggling to compete. The approach also offers advantages over traditional methods. Unlike pesticides or habitat manipulation, invasivorism is decentralized, involving scientists, citizens, and chefs in raising awareness while addressing a basic human need for food.
Unlike many environmental fixes, this one comes with a clear upside for everyday people: delicious new flavors, and a chance to participate in conservation without changing their entire lifestyle. From wild boar barbecue to Asian carp fish cakes, invasivorism demonstrates how environmental problems can sometimes become culinary opportunities. While not a complete solution, eating invasive species represents one creative tool in the broader fight to protect American ecosystems.
