How can I tell the difference between largemouth and smallmouth bass?

Telling the difference between largemouth and smallmouth bass can be a bit tricky, especially for new anglers. Both species belong to the same family, but they have distinct characteristics that can help you identify them on the water. Let’s dive into how you can easily distinguish between these two popular fish.

Physical Differences

One of the first things you’ll notice when trying to tell these two apart is their physical appearance. Here are some key features to look for:

• Body Shape: Largemouth bass typically have a deeper and bulkier body compared to smallmouth bass. If you see a fish with a more elongated body, it’s likely a smallmouth.
• Mouth Size: This is perhaps the most obvious difference. The largemouth bass has a mouth that extends past its eyes, while the smallmouth’s mouth is smaller and doesn’t reach as far.
• Coloration: Largemouth bass generally have a greenish hue with a lighter belly, often showing dark, blotchy markings. Smallmouth bass, on the other hand, tend to have a more bronze or brown coloration with vertical stripes or bars.
• Fins: The dorsal fin of the smallmouth is typically more pointed and has a more pronounced separation between the two sections, while the largemouth’s dorsal fin is more rounded.

Habitat Preferences

Where you find these bass can also give you clues about which species you’re dealing with. Largemouth bass are often found in warmer, shallow waters with plenty of vegetation, such as weedy lakes and ponds. They’re the fish that love to hide in the shade of lily pads or under overhanging trees.

Smallmouth bass thrive in cooler, clearer waters, often in rocky environments like rivers and lakes with a lot of structure. If you’re fishing in deeper, more flowing water, there’s a good chance you’ll encounter smallmouth bass.

Behavioral Traits

Understanding their behavior can also help you identify them. Largemouth bass are known for being more aggressive and are often targeted using various fishing techniques like topwater lures. They tend to strike harder, making them a favorite among many anglers.

In contrast, smallmouth bass are a bit more finicky. They tend to be more cautious and can be tricky to catch. When fishing for smallmouth, it’s beneficial to use lighter tackle and finesse techniques, such as drop shots or soft plastics. Their subtle bites can often be mistaken for just a bump, so pay close attention!

Size and Weight Differences

Generally, largemouth bass can grow larger than smallmouth bass. While both species can reach impressive sizes, a typical largemouth can weigh anywhere from 5 to 10 pounds or more, while smallmouths usually max out around 3 to 6 pounds. That said, trophy-size smallmouths do exist, but they are less common compared to their largemouth counterparts.

Identifying Young Bass

If you’re trying to identify young bass, the differences can be even less obvious. Young largemouths may look similar to smallmouths, but remember to check their mouth size and body shape. It can be easy to confuse them when they’re small.

Conclusion

Knowing how to tell the difference between largemouth and smallmouth bass can enhance your fishing experience and help you target the right species. Whether you’re navigating the shallow weedy waters or the rocky depths of a river, being able to identify these fish will make your time on the water more enjoyable and successful.
