Invasive crawfish found in Tilde Lake in NW Minnesota
ST. PAUL, Minn. — Another new invasive species has arrived in Minnesota.
Two red swamp crawfish, which are native to southeastern states, were recently found in Tilde Lake, northeast of Moorhead in northwestern Minnesota.
The Department of Natural Resources says they might have been castoffs from an aquarium or a crawfish boil. It's illegal to possess them or import them into Minnesota without a permit. And it's illegal to release them into the wild or use them as bait.
