What is a Smallmouth Bass?

The Smallmouth Bass (Micropterus dolomieu) is a freshwater fish that belongs under the sunfish family umbrella, although that might seem strange at first as they don’t quite look like other sunfish. The Smallmouth is a game fish, a type of fish pursued for sport by anglers. Game fish are often edible but some fishermen also enjoy catch-and-release. 

Why is it Called a Smallmouth Bass?

The Smallmouth earned its name due to how it can be differentiated from the Largemouth Bass. Smallmouths have jaws that do not extend past their eye sockets. These fish also go by the common names smallie, brown bass, brownie, bareback bass and lake bass. 

What Type of Fish is a Smallmouth Bass

Smallmouths are freshwater fish that belong to the sunfish family. Sunfish, by definition, are native to North America and have rayed fins. Unlike the majority of sunfish, Smallies aren’t considered panfish – meaning they don’t fit easily into a pan to be fried. They can get quite large. 

What is a Smallmouth Bass’ Habitat? 

Smallmouths prefers clear water and can be found in rivers, streams, and reservoirs. They’ve been introduced to many water sources, but can easily become invasive. Smallmouths like rocky and sandy bottoms as well as stumps in the water. They can put up with stronger currents and like cool temperatures, especially in the summer months when temperatures rise. 

Can Smallmouth Bass Live in Brackish Water? 

Yes – like their cousin the Largemouth, Smallmouth Bass are able to live in brackish water. But it isn’t necessarily their preferred environment. 

Where Can I Find Smallmouth Bass? 

This species is native to the Mississippi River basin, the Great Lakes, and the Hudson Bay basin. However, they’ve been introduced throughout almost every other part of North America, including Canada. In some cases this is intentional and done by stocking water sources. However some anglers have illegally introduced this species. 

What Do Smallmouth Bass Eat? 

Compared to other fish in the Sunfish family, Smallmouths can be considered picky eaters. They subsist mostly off of crawfish but will also feed on insects, small amphibians, and juvenile fish. 

How to Catch a Smallmouth Bass Fish

When it comes to catching Smallmouth Bass, keep in mind that they won’t eat just anything. Because of this, you’ll want to have a few different kinds of bait on your hands. Look into live bait to start – minnows or crawfish are a great option. You can pick live bait up right off the shore. 

Alternatively, many hard and soft baits mimic Smallmouth prey in a lifelike fashion and will probably draw their attention. Jigs that provide a good amount of action are also a great option.

Tube Jig

Tube Jigs work well with Smallmouths because they mimic one of their favorite prey crustaceans: crayfish. Although they look simple, tube jigs are well-known for catching Smallmouth Bass. 

Drop Shot Rig

Drop Shot Rigs allow anglers to send the line where they want it and keep bait hovering just over the bottom of the water column. They’re very effective in clear water, where fish can get a good look at what they’re hitting on. 

Spinnerbait

A type of lure meant to be a showstopper, Spinnerbait rigs are hybrid designs that usually flash and spin underwater to catch fishes’ attention.
