Species & Basics Glossary

Species & Basics

This category covers the foundational knowledge every bass angler needs, from telling the three major bass species apart to understanding the regulations and terminology you will hear at the ramp. Get these basics down and everything else in bass fishing, from lure choice to seasonal patterns, will make a lot more sense.

Largemouth Bass

The largemouth is the most widely targeted bass species in North America, identified by its upper jaw extending past the eye and a deep notch separating its two dorsal fins. They favor slower water with heavy cover like docks, grass, and laydowns, and they will eat a wider range of lure types than any other bass species. Most anglers cut their teeth on largemouth because they are aggressive, forgiving, and found in nearly every warm water lake and pond.

Smallmouth Bass

Smallmouth bass have a bronze to brown coloration, red eyes, and a jaw that stops at or before the eye. They prefer clearer, cooler water with rock, gravel, or current, which is why they dominate northern lakes and rivers. Pound for pound they fight harder than largemouth, and they respond well to jerkbaits and finesse presentations worked over rock structure.

Spotted Bass

Often called Kentucky bass, spotted bass look similar to largemouth but have a rough patch of teeth on their tongue and rows of dark spots below the lateral line. They tend to school tightly and relate to deeper, steeper structure than largemouth, often suspending over bluff ends or humps. Spots are common in reservoirs across the southeast and lower Midwest and can provide fast, non-stop action once you locate a school.

Catch and Release

Catch and release means returning a bass to the water alive after the fight instead of keeping it for food. Handle the fish with wet hands, avoid squeezing the belly, and get it back in the water quickly, especially in warm summer conditions when stress and low oxygen can be lethal. Practicing good release technique keeps fisheries healthy and keeps the bigger fish in the lake for the next angler.

Slot Limit

A slot limit is a regulation that requires anglers to release any bass falling within a specific length range, while allowing fish above or below that range to be kept depending on local rules. Slots are used to protect the mid-size breeding population and encourage harvest of smaller fish that are overpopulating a lake. Always check your state or provincial regulations before keeping any bass, since slot rules vary widely by body of water.

Live Well

The live well is the aerated tank built into a bass boat that keeps caught fish alive and healthy before release or weigh-in. A good live well circulates fresh, oxygenated water and should not be overcrowded, especially in hot weather when dissolved oxygen drops fast. Adding ice or a live well additive on tournament days helps reduce stress and mortality on fish you plan to release.

PB (Personal Best)

PB stands for personal best, the largest bass an angler has ever caught, usually measured by weight. Chasing a new PB is one of the main things that keeps bass anglers coming back to the water, and serious anglers will change locations, seasons, and techniques specifically to target the big female fish capable of breaking their record. Weighing and quickly photographing the fish before release lets you document a PB without harming it.

Skunked

Getting skunked means fishing an entire trip without catching a single bass. It happens to every angler at every skill level, often due to weather changes, heavy fishing pressure, or simply fishing the wrong depth or presentation for the day. A skunk is a good reminder to slow down, change locations, or try a different lure category rather than repeating the same failing pattern.

Honey Hole

A honey hole is a spot an angler has found that consistently produces quality bass, often kept secret and revisited season after season. These spots usually combine multiple key elements, like a hard bottom transition, current break, or isolated cover in an otherwise featureless area. Finding your own honey holes through map study and time on the water is one of the most valuable skills in bass fishing.

Structure

Structure refers to the permanent changes in bottom contour that hold and direct bass movement, such as points, humps, ledges, creek channels, and drop-offs. Unlike cover, structure does not go away with the seasons, which makes it reliable for locating fish year after year once you understand how bass relate to it. A good map or electronics unit is the fastest way to start identifying productive structure on unfamiliar water.

Cover

Cover is anything bass use for shade, ambush, or protection, including grass, docks, laydowns, rock piles, and standing timber. Bass relate heavily to cover because it breaks up current, provides shade from sunlight, and concentrates baitfish. Learning to read visible cover, and to imagine what is likely present underwater, is one of the fastest ways to start catching more bass consistently.

Thermocline

The thermocline is the layer in a lake where water temperature changes rapidly with depth, separating warmer surface water from colder, often oxygen-poor water below. Bass and baitfish typically stay above or right at the thermocline because water below it frequently lacks enough oxygen to support life. Understanding thermocline depth, especially in summer, helps explain why bass suddenly seem to disappear from deeper water.

Spawn

The spawn is the springtime period when water temperatures reach the mid to upper 60s and bass move shallow to build nests and reproduce. Males fan out circular beds in protected shallow areas, then females move in to lay eggs before the male guards the nest. This is when sight fishing becomes possible and big females are most vulnerable, which is why many anglers choose to practice careful catch and release during this window.

Post-Spawn

Post-spawn is the period immediately after spawning when female bass are recovering and feeding heavily to rebuild energy.

Frequently Asked Questions

What is the difference between largemouth and smallmouth bass?

Largemouth bass have a jaw that extends past the eye, a deep body, and a divided dorsal fin with a clear notch, and they prefer weedy, slower water. Smallmouth bass have a jaw that stops at or before the eye, a more bronze color, and favor rocky, cooler, current-driven water like lakes and rivers. Bite and fight differ too, smallmouth pull harder for their size and jump more.

What does 'structure' mean in bass fishing?

Structure refers to the physical shape of the bottom or water body, things like drop-offs, humps, ledges, points, and creek channels. Cover, by contrast, is objects bass relate to such as docks, weeds, rock, or wood. Knowing both terms helps when reading forums, maps, or talking to a guide about where fish set up.

What is a swim jig versus a football jig?

A swim jig has a bullet-shaped head and light wire hook designed to be reeled steadily through grass and cover without snagging, mimicking a baitfish. A football jig has a rounded head like its namesake, built to stand up hooks-up when dragged along rocky or hard bottoms in deeper water. Choosing the right one comes down to what the bottom and cover look like where you're fishing.

Does Glenmore ship bass tackle internationally, and is shipping really free?

Yes, Glenmore ships to the US, Canada, UK, EU, Australia, and New Zealand with free shipping on every order, no minimum required. Delivery times vary by region, but tracking is provided on all international orders so you always know where your gear is.
