“Fishes of Montana,” a free app that will help people identify different fish species, will launch this June. It will include fish that live in the state and some that don’t that state officials don’t want here.

The app was developed by High Country Apps in collaboration with scientists at Montana State University and Montana Fish, Wildlife and Parks. The scientists behind it hope it will help people get to know the state’s piscine inhabitants better.

FWP publicized the app with a video released this week. It will include photos, detailed descriptions and distribution maps for the fish species included.
