THE Montana Fish

Montana is proud of its trout. With the blackspotted cutthroat trout designated as the state fish, and more than six other kinds of trout swimming through the rivers and lakes, there is no shortage of the fish around here. However, there are many other notable species across Montana that are sought after by anglers, whether for their size, elusiveness or rarity. This begs the question, what is the Montana fish? From pike to paddlefish, landing one of these species could prove to be your best catch yet.

Northern Pike

Length: Up to 40"

Weight: Up to 20 lbs

While native to the west side of the state, this fish has grown in population across Montana. In the best conditions, pike can grow up to 40 inches long and weigh in at more than 20 pounds. If you’re looking for the state’s biggest pike, you’ll find them at Fort Peck Lake. This northeastern reservoir has produced many trophy pike, with the biggest tipping the scales at more than 30 pounds.

Both large and smallmouth bass are popular throughout the state, with summers being prime time to catch one. Typical bass can range in size from 12-24 inches depending on the species. Western Montana’s Flathead Lake is the best place to cast a line if you’re on the hunt for both kinds of fish.

These prehistoric fish hold the record for biggest in the state, with the heaviest catch coming in at almost 143 pounds. These fish — related to sturgeon and named for their distinctive paddle-like snouts — are found on the eastern side of the state, along the Missouri and Yellowstone rivers. With proper preparation and gear, these fish are a once-in-a-lifetime catch.
