In northern Minnesota, where the rusty crayfish has colonized more than 300 lakes, two local enterprises are offering a practical solution: harvest the invasive crustacean and sell it for consumption. The businesses, Crawdaddies and Northern Foragers, collect the crayfish, which are notorious for decimating native vegetation and even damaging wild rice crops, and market them to residents who want to enjoy a fresh, lake‑sourced protein.
Why the Rusty Crayfish Is a Problem
The rusty crayfish (originally from the Ohio River basin) arrived in Minnesota when anglers used it as bait. Once introduced, the species spreads rapidly, outcompeting native fish and munching down aquatic plants. Its voracious appetite can harm wild rice fields, a staple for many Minnesota families and an important cultural resource.
Local Entrepreneurs Step In
Crawdaddies and Northern Foragers have built modest operations focused on trapping the crayfish from affected lakes. In 2025, Crawdaddies reported pulling roughly 1,400 lb of rusty crayfish from Caribou Lake alone. The catch is cleaned, packaged, and sold directly to consumers who plan a traditional crayfish boil or simply want a novel addition to their dinner table.
From Lake to Plate at a James Beard‑Awarded Restaurant
One of the most visible customers is Bûcheron, a newly opened Minneapolis eatery that recently earned a James Beard Award for best new restaurant in the nation. Chef‑owner Adam Ritter, after learning the crayfish’s invasive status, embraced the opportunity to feature them on the menu. “Knowing these crayfish are harming our lakes, I’m proud to turn a problem into a delicious, responsibly sourced dish,” Ritter told MPR.
Community Benefits
Beyond providing a tasty meal, the initiative supports Minnesota’s tradition of self‑reliance and stewardship of natural resources. By creating a market for the unwanted species, the businesses help reduce crayfish populations while generating modest income for local entrepreneurs. The effort also raises public awareness about invasive species management, encouraging anglers to avoid using non‑native bait.
Looking Ahead
State wildlife officials continue to explore long‑term control methods, but the immediate impact of harvesting and selling the crayfish offers a tangible, community‑driven response. As more lakes report infestations, additional entrepreneurs may follow the model, turning an ecological challenge into a local economic opportunity.
For Minnesotans interested in trying the catch, both Crawdaddies and Northern Foragers list pickup locations and seasonal availability on their websites. The restaurants and home cooks who choose these crayfish are not only enjoying a unique flavor but also contributing to the health of the state’s waterways.
