The 2 fish are a part of the black bass (Micropterus) genus, which incorporates 13 acknowledged freshwater species native to North America. These carnivorous fish had been traditionally distributed all through the jap a part of the continent, all the way in which from the Rocky Mountains to the Atlantic coast, and from Hudson Bay right down to northeastern Mexico.
A few of these species, such because the Cahaba bass, Guadalupe bass, and Suwanee bass, nonetheless occupy a really small vary within the U.S. (Guadalupe bass can solely be discovered within the spring-fed rivers of Central Texas, for instance.) Different species, like noticed bass and redeye bass, have bigger dwelling ranges and could be present in a number of states. However none are as broadly distributed as largemouth and smallmouth bass.
Due to their big recognition as a sport fish, largemouths and smallmouths have been stocked extensively west of the Rockies, and smallmouth bass are actually current in all however two states (Louisiana and Florida) within the Continental U.S. Largemouth bass, in the meantime, inhabit 49 states and have even been caught in Alaska.
In actual fact, the 2 bass species have change into so well-liked in sportfishing circles that they’ve been launched to different nations as nicely. (Japan particularly has a thriving bass fishing scene.) Biologists now contemplate these bass to be “cosmopolitan” species, which implies they are often discovered virtually anyplace on the planet.
Each sorts of bass are extremely environment friendly apex predators that seek out baitfish and different prey. What do bass eat? The straightforward reply is: Something that may match of their mouths. However a few of their commonest prey gadgets embrace minnows, crayfish, bugs, and amphibians.
The 2 fish have barely totally different searching kinds, nonetheless. Largemouth bass are basic ambush predators, which implies they like to cover in heavy cowl, lie in wait, and assault their prey because it passes by. Smallmouths, in the meantime, are extra apt to maneuver round and chase bait out within the open. Like most fish, each species have a lateral line, which is a sensory system that enables them to select up on vibrations and different actions within the water. (Extra on this within the ideas part beneath.)
Determine Largemouth Bass vs Smallmouth
The 2 black bass species have the same form and physique profile, however every has a couple of key bodily traits that may assist with identification.
The obvious distinction between the 2 is—you guessed it—the scale of their mouths. Largemouth bass have greater maws, and their higher jaw extends nicely previous the eyeball, whereas a smallmouth’s higher jaw falls consistent with the eyeball. For many anglers, that is the best solution to inform the 2 species aside.
One other solution to distinguish the 2 is by taking a look at their dorsal fins. Each fish have two dorsal fins, however largemouths have a tell-tale break between the fins, whereas smallmouths have clearly related dorsal fins.
Their coloration may also assist with identification. Though this will change relying on the water physique and from one particular person to a different, smallmouth bass sometimes have brown our bodies, and largemouth bass are normally extra of a inexperienced shade. (Some anglers consult with smallmouth as “brown bass” and largemouth as “inexperienced bass” for this very cause.)
| Largemouth Bass | Smallmouth Bass | |
| Common Weight | 3-7 kilos | 2-4 kilos |
| World-File Weight | 22 kilos, 4 ounces | 11 kilos, 15 ounces |
| Coloration and Look | Inexperienced shade with a horizontal stripe on its sides | Brownish bronze shade with vertical bars on its sides |

The place to Discover Largemouth Bass and Smallmouth Bass
Though every bass species could be present in almost each U.S. state, there are some primary tips for the place to search out good numbers of largemouth bass vs smallmouth.
Smallmouth have traditionally been a northern species, whereas largemouth bass have been synonymous with Southern latitudes. That is nonetheless the case to an extent, however the two species have been stocked so closely all through North America that their ranges now overlap. Right this moment, they inhabit lots of the similar water our bodies (and, like many anglers, I’ve caught largemouth and smallmouth bass from the identical stretch of river on the identical day).
Since they like totally different water varieties, nonetheless, the 2 species don’t sometimes hang around collectively. Smallmouth bass are extra tolerant of chilly water and like water temperatures within the mid-60s to mid-70s. Largemouth bass are extra at dwelling in hotter water, preferring water temps within the higher 70s to mid 80s.
Present, water readability, and habitat varieties are different issues when looking for bass. Basic largemouth water in a river could be a murky, slow-moving bend with thick cowl (assume fallen bushes, heavy vegetation, and boat docks). Smallmouth bass are extra typically present in areas with present, clear water, and structured bottoms (assume rocky shoals, factors, and riprap shorelines.)
Catch Largemouth vs Smallmouth Bass
Bass fishing could be as easy or as difficult as you need to make it. Each largemouth and smallmouth bass could be present in sprawling reservoirs, however it may be troublesome to fish these lakes successfully and not using a boat. Nearly all event anglers use specialised bass boats full with flat decks, aerated livewells, and enormous, highly effective outboards that enable them to maneuver rapidly and canopy water effectively.
The finest bass boats for the common angler aren’t essentially the most costly, nonetheless, and also you don’t actually want one of many high-dollar glitter boats you see on TV to catch fish. An previous jon boat will get the job accomplished, as will a canoe. A rising variety of anglers are additionally embracing kayaks for bass fishing, and due to advances in battery expertise and boat design, the game has exploded lately.
You may nonetheless catch fish in case you’re boatless, too. Each bass species are sometimes discovered alongside perimeter shorelines, and a shore-bound angler can normally discover loads of good holding spots.
Ponds, creeks, and different small waterbodies also needs to not be neglected. Relying on the place you reside, even the smallest ponds can maintain bigmouth bass. Farm ponds are most likely the most effective locations for newcomers to start out, and if you may get permission to fish one in all these non-public ponds, you’re virtually assured to have some motion.
When you discover a waterbody to fish, a primary spinning rod or baitcaster setup spooled with eight- to 20-pound check is enough. Simply seize a handful of the finest bass lures in a couple of totally different colours and sizes and begin experimenting. Or, if you wish to make issues as straightforward as potential, pin some dwell bait on a hook underneath a bobber and wait.
Bass Fishing Ideas from the Execs
To get a greater concept of the totally different approaches that anglers take when focusing on largemouth bass vs smallmouth, Out of doors Life caught up with two fisheries biologists in several elements of the nation. One primarily chases largemouth bass within the South, whereas the opposite fishes largely for smallmouths within the Midwest. Each scientists are additionally event bass fisherman.
Ideas for Catching Largemouth Bass
Todd Driscoll is a district fisheries biologist for Texas Parks and Wildlife, and he lives and fishes in deep East Texas, which is basic largemouth nation. He frequents massive reservoirs like Sam Rayburn and Toledo Bend, focusing on areas with thick cowl and heavy vegetation. As a result of he typically fishes in and round lily pads, fallen bushes, and stumps, Driscoll makes use of a variety of mushy plastics for bass and rigs them weedless to keep away from getting hung up. The important thing to catching largemouth bass, he says, is knowing the obtainable forage in any given lake and maintaining in thoughts that their lives revolve virtually completely round meals.
“I’d classify largemouth bass as opportunistic feeders and intensely adaptable apex predators,” Driscoll says. “Like Rick Clunn used to say: ‘Discover the bait, discover the bass.’ There’s a complete lot of reality to that.”
The one exception, he notes, is when largemouth bass are spawning and aren’t as involved with trying to find prey. However even then, you’ll be able to nonetheless persuade a bass to eat a lure.
“That’s the time when a variety of finesse strategies—like weightless mushy plastics or wacky worms—come into play,” he explains.
Though he considers largemouth bass to be “primarily sight and sound feeders,” Driscoll typically fishes in murky water the place it’s onerous for fish to hunt by sight alone. To get a response in these conditions, he likes to make use of buzzbaits, spinnerbaits, and different lures that transfer a variety of water and can set off a bass’ lateral line.
“Typically you’ll be able to fish one thing that’s completely irregular to get that ‘reflex chew’ out of bass,” Driscoll says. “Anglers can benefit from [their] aggressive nature.”
Ideas for Catching Smallmouth Bass
In the meantime, up North across the Nice Lakes is the place you’ll discover NOAA fisheries biologist and smallmouth bass guru Jeff Elliott. Like Driscoll, Elliott fished in bass tournaments earlier than he grew to become a scientist, and each views have formed his understanding of what makes bass tick.
As a result of the Nice Lakes are deeper than the warm-water reservoirs of East Texas, Elliott typically targets bass extra towards the bottoms of those lakes, the place smallmouth prefer to stack up among the many rocks. The water there may be additionally a lot clearer, so Elliott doesn’t fear as a lot about triggering a smallie’s lateral line.
“Sight feeding is a smallmouth’s greatest factor,” he says, “far more so than the lateral line.”
As an alternative, he focuses extra on imitating the gobies, alewives, and different prey that smallmouth key in on. And since these baitfish are extremely migratory, he’s continuously monitoring their migrations as a way to keep on the bass. (Keep in mind: Discover the bait, discover the bass.)
“Smallmouth bass are very nomadic,” Elliot says. “They transfer so much, and as quickly as they’re accomplished spawning, they’re able to observe the meals.”
From an angling perspective, this is without doubt one of the most vital variations between largemouth bass and smallmouth bass: The largemouth is extra of a homebody, whereas the smallmouth is extra of a traveler. Elliott, who’s additionally caught loads of largemouth bass, says that in his expertise, smallies are far more keen to maneuver round and actively hunt for prey.
“Smallmouth bass fishing is a lot totally different than fishing for largemouth,” he says. “Largemouth bass simply need to sit someplace, be lazy, and use their ambush expertise to get fed. Whereas a smallmouth bass is simply gonna go after it.”
