Rusty Crayfish -- learn how to identify, stop the spread and report sightings
Colorado Department of Natural Resources. Division of Wildlife.
The Colorado Division of Wildlife is monitoring the state's waters for the introduction of an aggressive invasive species, the rusty crayfish. Rusty crayfish were found for the first time in Colorado during routine sampling operations in 2009 in the Yampa River drainage between Steamboat Springs and the town of Yampa. Because of their larger size and more aggressive nature, rusty crayfish can impact fish populations by consuming small fish and fish eggs, and negatively impact fish and spread unwanted aquatic plants by aggressively harvesting underwater plant beds. Learn more how to identify the rusty crayfish, how to stop the spread and how to report sightings.
