Imagine serving your guests a rich, aromatic gumbo — the kind that fills the kitchen with warmth and draws everyone to the table. Now imagine telling them the star protein tastes like rabbit, costs next to nothing, and actually helps restore fragile wetland ecosystems.
Welcome to the world of invasivorism, where your adventurous palate becomes an act of conservation.
The U.S. Fish and Wildlife Service (FWS) is actively encouraging people to eat invasive species to protect native animals and ecosystems. And before you wrinkle your nose, consider this: the flavor profiles are genuinely compelling, the cooking methods are familiar, and the environmental payoff is real.
What Is Invasivorism — and Why Should Home Cooks Care?
Eating invasive species, also known as “invasivorism,” is nothing new.
The term was first coined in 2010 by New York Times journalist James Gorman. Since then, the concept has steadily grown from a niche ecological idea into a genuine food movement.
Picture this: you’re a scientist digging near the Amazon rainforest, and you pull a jawbone out of the ground that looks so wrong you assume it broke underground. Then you find another one. Same weird twist. Then another. And another. Nine total, each with the same baffling shape. That’s exactly what happened to a team […]
Many organizations have started to hold hunting tournaments and derbies to help deplete populations of invasive species. Some even partner with local diners to add the species to their menus — meaning you might find these unconventional proteins on a restaurant plate near you.
For the home cook, invasivorism offers something irresistible: guilt-free protein that actually helps the environment. Every bite reduces the population of creatures that are actively devouring native plants, destabilizing ecosystems and tearing up farmland.
The economic stakes are enormous.
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.
“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,” the FWS wrote in a 2025 article.
So what’s on the menu? Let’s break it down, species by species.
Swamp Rats: The Lean Star of Your Next Gumbo
First on the FWS list is nutria — also known as swamp rats. Yes, you read that correctly. But set aside the name for a moment and focus on what matters: flavor and texture.
The FWS describes nutria as “oversized, wetland-loving rodents” native to South America that are devouring marshlands in the Gulf of America Coast, Atlantic Coast and Pacific Northwest.
Their suggestion for the kitchen? Cook yourself up a bowl of nutria gumbo. “Their meat is lean, mild, and tastes like rabbit,” the FWS adds.

For home cooks familiar with braising rabbit or using it in stews, nutria slots right into your existing repertoire. That lean, mild profile means it takes beautifully to bold Cajun seasonings, a dark roux, and slow simmering alongside okra and andouille.
Northern Snakehead: A Firm, Flaky Taco Night
If you’re a fish taco devotee — and who isn’t — the northern snakehead deserves a spot on your radar.
This invasive, predatory freshwater fish is native to Asia, and its ability to spend several days out of water allows them to wiggle their way across land into new freshwater habitats. They’re frequently seen in Mid-Atlantic and Southeastern U.S. waterways.
“Luckily, they’re delicious with a firm, white, and flaky meat,” the FWS wrote in 2025.
The FWS also suggests grilling or frying northern snakehead meat, adding that they make excellent fish tacos. Think a crispy battered fillet tucked into a warm tortilla with a bright slaw and a squeeze of lime.
Silver Carp: Surprisingly Tasty Crispy Fish Cakes
Can’t find northern snakehead meat? Then try the high-jumping silver carp — frequently seen in Midwest and Southeast rivers and lakes.
The FWS suggests trying them grilled, blackened or turning them into crispy fish cakes because they’re “surprisingly tasty.” For the home cook, fish cakes are a perfect gateway preparation: flake the meat, bind it with egg, season generously, form into patties and pan-fry until golden and crunchy on the outside.
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 […]
Serve with a remoulade or tartar sauce, and you have a dish that could easily anchor a weeknight dinner or impress at a Saturday gathering.
Green Iguana: The Chicken of the Trees
Next up on the menu? Iguana stew. The FWS describes the green iguana as the “chicken of the trees” due to its mild flavor — a nickname that immediately signals versatility in the kitchen.
Green iguanas are native to Central and South America, but are currently eating native plants and destabilizing seawalls in Florida and other warm states.
For Florida-based home cooks and locavores especially, this presents a fascinating opportunity: a locally sourced, hyperlocal protein that practically asks to be braised low and slow into a comforting stew.
Wild Boar: The Crown Jewel of Invasive Proteins
And last but not least, you can cook yourself up a plate of feral hogs or wild boar.
Native to Europe and Asia, these hogs and boar are invasive in Southeastern U.S., Texas and California. They tear up farmland, forests and wetlands and devour anything in their path.
“But there’s a silver lining because wild boar is some of the best-tasting invasive meat you can get,” the FWS writes, adding that the meat is “leaner and richer in flavor than store-bough pork.”
The meat makes a good smoked barbecue, hearty chili, burger, taco or ragu over pasta. For the home cook, that ragu alone is worth the exploration — imagine a slow-cooked wild boar sauce, richer and more complex than anything from conventionally raised pork, ladled over fresh pappardelle. That’s a dinner party centerpiece.
Beyond the FWS List: More Species Worth Exploring
According to Eat the Invaders, a website created by University of Vermont conservation biologist Joe Roman, the FWS’ list is only the beginning of what you can put on your next plate.
Some of the species listed on the website include lionfish, garden snail, armored catfish, crayfish and common carp — expanding the possible pantry for any adventurous cook even further.
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 food-curious cooks looking for the next sustainable, conversation-worthy protein, the invasive species menu is open — and it’s surprisingly delicious.
