What is Spotted Bass?

Fresh Caught Spotted Bass

The spotted bass, commonly known as spotty or spots in certain fishing areas, is a freshwater fish from North America that belongs to the Centarchidae family of the order Perciformes. It gets its name from the rows of black dots that appear below the lateral line. It is endemic to the basin of the Mississippi River and the Gulf states, from middle Texas to the Florida panhandle, and is one of the black basses.

It was introduced to Virginia and western North Carolina from its original area in the west Mid-Atlantic states. Unfortunately, people brought spotted bass to southern Africa, where it has established itself as an invasive species in certain isolated waterways.

Because of the coloring, many fishers mistake spotted bass for largemouth bass. However, there are significant distinctions. For example, smallmouth bass or “smally” and spotted bass are sometimes confused, although the spotted bass lacks the vertical bars on the sides of the smallmouth’s body. Once caught, you can grill spotted bass as they have flaky, firm white meat.

What is Largemouth Bass?

The largemouth bass is a predatory freshwater gamefish belonging to the Centrarchidae sunfish family native to the central and eastern United States, southeastern Canada, northern Mexico, and other vast freshwater sources.

It has numerous other names, including Widemouth bass, black bass, Bigmouth bass, Florida bass, bucket mouth, largies, Potter’s fish, Florida largemouth, green bass, green trout, Gilsdorf bass, LMB, and southern and northern largemouth bass are some of the regional names.

The largemouth bass appears as an olive-green to greenish-gray fish with a jagged horizontal stripe down each side formed by a succession of dark, often black, blotches. When largemouth bass is around a year old, they attain sexual maturity and begin spawning. Spawning occurs in the spring when water temperature first rises to 60 degrees Fahrenheit (16 degrees Celsius) for an extended time.

Anglers prize largemouth bass for the thrill of their ‘battle’ when catching the fish. In their attempt to toss the hook, the fish will frequently get airborne, although many believe that its related species, the smallmouth bass, is much more aggressive.

Spotted Bass vs. Largemouth Bass: Habitat and Distribution

Spotted and largemouth bass favor distinct environments, as most experienced angler knows. While they both live in the eastern and central United States, they prefer to cluster in different bodies of water.

Spotted bass, for example, can be found in fast-moving rivers and streams with rocky bottoms. Largemouth bass, on the other hand, prefers slower-moving, clear water. Furthermore, the spotted bass is more tolerant to warm water than largemouth bass.

The largemouth bass is the state fish of Mississippi and Georgia and the state freshwater fish of Florida and Alabama. At the same time, the Ohio River basin and the central and lower Mississippi River basins are home to spotted bass.

Identifying Largemouth Bass And Spotted Bass


When comparing both fish side by side, it’s clear that the largemouth is substantially larger. Spotted bass may reach lengths of 25 inches and weighs 11 pounds. Meanwhile, the largest largemouth fish may grow up to 29.5 inches long and weigh 22 pounds and 4 ounces. The longest and biggest fish are breeding females, which anglers catch and release to keep the local population healthy.


The jaws of these two fish should be the first thing you notice about them. Largemouth bass has a large jaw that extends over its eye on top and sticks out far more on the bottom. The upper jaw of spotted bass is smaller and does not reach past the eye. Spotted bass has mouths with almost equal jaws on top and bottom.

Dorsal Fin

Both species have spiky and soft dorsal fins that look identical when laid flat. However, when you lift their fins, the similarities start to diminish. This is because a membrane joins the two fins of spotted bass. Meanwhile, the two fins are virtually entirely separated in largemouth bass because there is no such membrane.


If you’re holding a bass fish and aren’t sure what it is, open its mouth and examine the tongue. A rough patch will be present in a spotted bass tongue. On the other hand, largemouth bass has a smooth tongue. Although it is a slight distinction, it is noticeable if you look closely.


The scales on spotted bass cheeks vary in size depending on their location. The upper cheeks have larger scales, whereas the lower cheeks have smaller scales. Largemouth bass cheek scales do not have the same degree of variation between upper and lower cheeks. Furthermore, largemouth bass cheek scales are more prominent on average than spotted bass cheek scales.


The Largemouth bass is greenish-grey on top, black on the gill covers, and occasionally a mix of greenish-grey and silvery or blue on the sides. The Spotted Bass, on the other hand, has a yellowish-green body with dark olive to brown top. In addition, spotted bass, like the Largemouth, has black patches on the top of their bodies.

Lateral Line Markers

Dark-edged, prominent scales can be found between the lateral line and the dark horizontal band on spotted bass. On the other hand, largemouth bass has fewer noticeable scales in the same place, giving them a smooth appearance.
