Introducing FISHES OF MONTANA!

Home Screen

Simple to use, all inclusive, no connection needed--your all-in-one guide to identifying fishes in Montana!

  • Fishing in Montana this year just got more interesting thanks to FISHES OF MONTANA!
  • Montana State University Department of Ecology, USGS, and Montana Fish, Wildlife & Parks have combined forces to produce the most up-to-date montana fish species information available!
  • FISHES OF MONTANA gives fishermen the ability to identify each of the 100 species (90 of which are native) in the state!
  • Provides information critical to preventing Aquatic Invasive Species from entering our state's waterways!
  • Each species includes a full set of images, range map, preferred habitat, size, appearance, food habits, and similar species!
  • No WiFi or cellular connection needed to use FISHES OF MONTANA! Why? Because fishing and exploring in our state often means being on the water, in wild country, with the nearest cellular service (much less WiFi) 3 counties away. So almost every aspect* of FISHES OF MONTANA works regardless if the nearest cell tower is 3 counties away. (*the single exception is if you tap links to websites that are not core to the app)
  • Highly intuitive—We want you to spend your time enjoying the outdoors, not learning how to use our app!

Press Reviews

  • FISHES OF MONTANA app to launch next month
    --Bozeman Chronicle (May 31, 2019)
    There are more than 90 species of fish in Montana, and it can be hard to keep them all straight. Soon, there will be an app for that. “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.
