In 2025, Minnesota businesses began capturing and serving invasive rusty crayfish to address their rapid spread across state waters. The initiative targets a species that has colonized 300 lakes in the region.
Why it matters
The rusty crayfish, native to the Ohio River, causes significant ecological damage, including the consumption of wild rice crops. Because few other eradication methods exist for the species, harvesting serves as a practical way to manage populations that were originally introduced as fishing bait.
Commercial harvest records show that Crawdaddies captured 1,400 lbs. of invasive rusty crayfish from Caribou Lake in 2025. This effort focuses on mitigating a species that has already established populations in 300 lakes across Minnesota.
The players
Bûcheron
A Minneapolis restaurant recognized with a James Beard Award that includes invasive rusty crayfish on its menu.

The details
Businesses such as Crawdaddies and Northern Foragers use specific harvesting methods to capture the crayfish from infested lakes. Once removed, the crayfish are processed for personal use or supplied to establishments like the Minneapolis restaurant Bûcheron for their food menus. This approach aims to reduce the presence of a species that otherwise lacks effective natural population controls in Minnesota environments.

Health Landscape
The use of harvesting to control the rusty crayfish represents a shift toward utilizing market-based solutions for invasive species management. This effort follows a pattern set by the Minnesota Department of Natural Resources invasive species management protocols by utilizing removal to curb ecological damage.
Consumers interested in local food sustainability can support these management efforts by choosing invasive species options when they appear on restaurant menus. If you are concerned about the ecological health of local waters, consult your doctor or a local environmental agency regarding safety guidelines for handling or eating wild-caught local specimens.
The takeaway
Commercial harvesting of invasive rusty crayfish provides a practical method for reducing the ecological impact of this non-native species. Residents can support these state-wide management efforts by being aware of regional efforts to turn invasive pests into sustainable food sources.
