Ask a fisheries biologist: Wisconsin’s native and non-native species

This week, DNR fish biologist Max Wolter discusses our native species and those that are non-native.

They play a beloved role in Wisconsin’s fishing culture, and anglers are excited to pursue them in local waters. However, there are parts of the world where these species should not be found and have a completely different reputation.
