Get ready for Snapshot Day with out Aquatic Invasive Species of the Week series! This week's AIS is the rusty crayfish.

This AIS hails from the Ohio River basin. The crayfish's suspected method of transport to Wisconsin was anglers who used it as fishing bait. This species poses a host of potential threats to our state's waters such as displacing native crayfish, eating fish eggs, and eating aquatic plants that provide food and shelter to other water inhabitants.

To search for the rusty crayfish and more AIS in Wisconsin, join us on August 10th for Snapshot Day! Learn more and register at https://wateractionvolunteers.org/events/.
