Fishes of Montana

About this app

FISHES OF MONTANA is a collaborative effort between Montana State University's Department of Ecology, Montana Fish Wildlife & Parks, and MountainWorks Software. FISHES OF MONTANA provides an easy-to-use visual reference and interactive keys to the 90 species known to be found in the waters of Montana, and 10 Aquatic Invasive Species that we wish to keep out of Montana. A user can identify a fish visually by browsing through images of fish, search by name and family, or by using identifying characteristics such as fin structure, location of mouth, or geographical location. Each species is profiled to include images of the fish, range maps for both Montana and the U.S., preferred habitat, adult size, appearance, life history, similar species, and more!

Ratings and reviews

excellent resource for out of state anglers. tons of fish nerd stuff. works on airplane mode which is ideal for reference in the field. trusted sources of information and no unnecessary bells and whistles.

Extremely helpful to identify any species of fish you aren't entirely familiar with. I love the feature that let's you see species listed by characteristics you can pick.

As a multi-species fisherman, I love the information this app contains for my home state. I will be referencing and studying this information regularly.
