Picture serving your guests a hearty, fragrant gumbo — the type that warms the kitchen and brings everyone together at the dining table. Now imagine revealing that the main ingredient, which tastes like rabbit, is affordable and plays a part in revitalizing delicate wetland habitats.
Welcome to invasivorism, where adventurous eating aligns with conservation efforts.
The U.S. Fish and Wildlife Service (FWS) is promoting the consumption of invasive species to safeguard native wildlife and ecosystems. While this might initially sound unappealing, consider this: the taste profiles are genuinely enticing, the preparation techniques are familiar, and the environmental benefits are significant.
Understanding Invasivorism and Its Appeal to Home Cooks
The practice of consuming invasive species, or “invasivorism,” is not a novel concept.
The term was first introduced in 2010 by New York Times journalist James Gorman. Since then, it has evolved from a niche ecological idea into a recognized culinary movement.
Various organizations now host hunting events and derbies to manage invasive species populations. Some even collaborate with local restaurants to feature these species on their menus, making it possible that you might encounter these unconventional proteins at a nearby eatery.
For home cooks, invasivorism presents an enticing opportunity: a guilt-free protein source that aids the environment. Each bite helps decrease the numbers of species that threaten native plants, disrupt ecosystems, and damage agricultural lands.
The financial implications are substantial.
According to the U.S. Department of Agriculture, “invasive species have cost North America $2 billion per year in the early 1960s to over $26 billion per year since 2010.” Globally, it is estimated that the economic cost of invasive species has been $1.288 trillion over the past 50 years.
The FWS noted in a 2025 article, “Eating invasive species can help protect native animals and plants. By hunting, trapping, and eating these invaders, we can reduce their numbers and the harm they cause.”
So, what’s on the menu? Let’s explore, species by species.
Swamp Rats: A Lean Highlight for Your Next Gumbo
Leading the FWS list is nutria, also known as swamp rats. Yes, that’s correct. But don’t let the name deter you — focus instead on its taste and texture.
Described by FWS as “oversized, wetland-loving rodents” from South America, nutria are consuming marshlands along the Gulf of America Coast, Atlantic Coast, and Pacific Northwest.
In the kitchen, try a nutria gumbo. According to the FWS, “Their meat is lean, mild, and tastes like rabbit.”

For those experienced with cooking rabbit or stews, nutria fits seamlessly into their culinary skills. Its lean, mild nature pairs well with bold Cajun spices, a rich roux, and slow cooking with okra and andouille.
Northern Snakehead: A Flaky Addition to Taco Night
For fans of fish tacos — and who isn’t? — the northern snakehead should be on your list.
This invasive, predatory freshwater fish originates from Asia, and its ability to survive several days out of water allows it to move across land to new freshwater environments. It is often found in Mid-Atlantic and Southeastern U.S. waters.
The FWS noted in 2025, “Luckily, they’re delicious with a firm, white, and flaky meat.”
The FWS suggests grilling or frying northern snakehead meat, noting that it makes excellent fish tacos. Picture a crispy, battered fillet nestled in a warm tortilla with fresh slaw and a splash of lime.
Silver Carp: Surprisingly Delicious Fish Cakes
If northern snakehead isn’t available, consider the high-jumping silver carp, often found in Midwest and Southeast rivers and lakes.
The FWS recommends grilling, blackening, or turning them into crispy fish cakes because they’re “surprisingly tasty.” For home cooks, fish cakes are an ideal starting point: flake the meat, bind it with egg, season well, form into patties and pan-fry to a golden, crunchy finish.
A massive Kemp’s ridley sea turtle — the world’s smallest and most critically endangered sea turtle species — washed ashore on a Galveston, Texas, beach on March 7, 2026, launching an emergency rescue that has her fighting for survival at the Houston Zoo. And her story is arriving alongside a feel-good milestone: 27 turtles of […]
Pair with remoulade or tartar sauce for a dish that serves as a weeknight dinner or shines at a weekend gathering.
Green Iguana: The “Chicken of the Trees”
Next on the list is iguana stew. The FWS likens the green iguana to the “chicken of the trees” because of its mild flavor, indicating its versatility in cooking.
Originating from Central and South America, green iguanas are currently consuming native plants and destabilizing seawalls in Florida and other warm states.
For Florida-based cooks and locavores, this presents an intriguing chance: a locally sourced protein that begs to be slowly braised into a comforting stew.
Wild Boar: The Gem of Invasive Meats
Finally, you can prepare a dish of feral hogs or wild boar.
Native to Europe and Asia, these animals are invasive in the Southeastern U.S., Texas, and California, where they destroy farmland, forests, and wetlands.
The FWS writes, “But there’s a silver lining because wild boar is some of the best-tasting invasive meat you can get,” noting its “leaner and richer flavor than store-bought pork.”
Wild boar meat is ideal for smoked barbecue, hearty chili, burgers, tacos, or ragu over pasta. For home chefs, that ragu is worth exploring — imagine a slow-cooked wild boar sauce, richer and more complex than any conventional pork, served over fresh pappardelle. It’s a dinner party centerpiece.
Beyond the FWS List: Additional Species to Consider
According to Eat the Invaders, a website established by University of Vermont conservation biologist Joe Roman, the FWS’ list is just the beginning of what you can explore in your kitchen.
The website includes species like lionfish, garden snail, armored catfish, crayfish, and common carp, further expanding the options for any culinary adventurer.
If you scrolled through social media recently and saw an outlandish story about a Florida man claiming he was abducted by dolphins and forced to build them an underwater city, you weren’t alone. The tale spread across Facebook, Instagram and TikTok — and it was entirely fake. The viral claim has been confirmed as satire […]
For cooks eager to try the next sustainable and conversation-worthy protein, the menu featuring invasive species is open and surprisingly tasty.
