Difference between Smallmouth and Largemouth Bass

In freshwater fishing, there are two main types of bass that are sought after by anglers: the smallmouth and largemouth bass. Though both fish look similar, there are some distinct differences between these two species. In this blog post, we will take a look at those differences and help you determine which type of bass is right for you. Let’s get started!

What is Smallmouth Bass?

Smallmouth Bass (Micropterus dolomieu) is a species of freshwater fish in the sunfish family. It is native to North America and is most commonly found in the Great Lakes and Mississippi River basins. Smallmouth Bass are olive-green in color with brown mottling and dark vertical bars on their sides. They have a relatively large mouth and a distinctive streamlined body shape. Adults can reach lengths of up to 30 inches and weights of up to 10 pounds. Smallmouth Bass are popular gamefish and are prized for their fight when hooked. They are also popular among anglers for their eating qualities. Smallmouth Bass are opportunistic feeders and will eat a variety of prey items, including insects, crayfish, and small fish.

What is Largemouth Bass?

Largemouth Bass are a type of freshwater fish that are native to North America. They are members of the sunfish family and are one of the most popular game fish in the United States. Largemouth Bass are easily identified by their large mouths, which can extend past the eye when the fish is opened. They are greenish-brown in color with dark spots on their body and fins. Largemouth Bass typically grow to be between 16 and 24 inches long and weigh 4-6 pounds. Largemouth Bass are found in lakes, ponds, streams, and rivers across the United States. They prefer habitats with little or no current and plenty of places to hide, such as aquatic vegetation, logs, rocks, or docks. Largemouth Bass are carnivores and feed on smaller fish, insects, crayfish, and frogs. Largemouth Bass are prized by anglers for their fierce fighting when hooked and are a popular target for both recreational and competitive fishing.

Difference between Smallmouth and Largemouth Bass

  • Smallmouth and largemouth bass are two of the most popular fish for anglers in North America. Both species are highly sought after for their impressive size and fighting ability. But what exactly is the difference between these two iconic fish? The most obvious difference is in their size. Smallmouth bass typically grows to be around 18 inches long, while largemouth bass can grow to be twice that size. This difference is reflected in their respective weight limits. Smallmouth bass has a max weight of around eight pounds, while largemouth bass can reach up to 20 pounds or more.
  • Another significant difference is in their habitat preference. Smallmouth bass prefers clear, cool waters, and are often found in rivers and streams. Largemouth bass prefers warm, murky waters, and are typically found in lakes and ponds. This difference is likely due to the fact that smallmouth bass requires more oxygen than largemouth bass.
  • Finally, smallmouth and largemouth bass differ in their feeding habits. Smallmouth bass is opportunistic feeders that will eat just about anything they can fit into their mouths. Largemouth bass, on the other hand, is more selective eaters and tend to prefer live baitfish. While there are several key differences between smallmouth and largemouth bass, both species remain popular targets for anglers across North America. So whether you’re chasing trophy fish or just looking for a good fight, these two species are sure to provide you with an enjoyable experience.


Smallmouth and largemouth bass are two of the most popular types of fish for anglers in North America.
