Up your Catch with this easy-to-follow look at the behaviour of North America's favourite gamefish, the Largemouth Bass. Understanding his behaviour and where he is most likely to be throughout the year, will catch you more fish.

The Nature of the Largemouth Bass

Think of the Largemouth Bass like a mugger. He usually works on his own and will skulk around in the shadows waiting for a hapless victim to pass by. He will dart out, swallow his prey whole with that huge bucketmouth, and then retire back into his cover to digest his meal.

Largemouth are superbly camouflaged to hide in shadows, with their dark green colouration and the bars on their sides to break up their outline. It's somewhat like you sitting in a darkened room looking out of the window, into the daylight. You can see people passing by but they can't see you.
   
Largemouth will eat almost anything that will fit in their mouths; baitfish, crayfish, leeches, mice, frogs, ducklings etc. A 3lb Largemouth will eat a 6 to 8 inch baitfish without breaking stride. Most of the baits fishermen have traditionally thrown for Largemouth, are far too small and would only represent a mere morsel to a hungry Bass, of a decent size.

General Observations

You will rarely find Largemouth on a mid-lake hump or out in the middle of a natural lake. This is, unless the lake has very little cover and the Bass school to feed on roaming baitfish such as Shad. Largemouth, otherwise, have a fairly tight home range. They will tend to be in areas which are in some way, connected to the shoreline. Reservoir Bass can seem to break this rule of thumb, but will still relate to the old creek channels and use them as we would a highway.

How Weather Affects Bass Behaviour

If the weather conditions have been stable for a couple of days, Bass are likely to be actively looking for food and will station themselves at suitable ambush points such as the edge of the weedbeds. Target irregularities in the weedbed such as points, turns, recesses etc.

Largemouth will be most aggressive in lowlight conditions; overcast skies, early in the morning, late in the day. They will generally be roaming out in the open, actively looking for food.

They are also super aggressive just before a rainstorm. I have heard several theories as to why this is but the one that makes the most sense to me is that Largemouth evolved to live in rivers. When it rains heavily, run-off causes the water to become very dirty. The visibility is greatly reduced, making it difficult for the Bass to hunt their food. Therefore, they put on the feedbag before the storm in preparation for the lean times ahead.

The hour or two just before a storm can provide some of the hottest action you have ever seen. However, if there is any chance of lightning, even if it is a distance away, stop fishing and get off the water immediately. Lightning can still strike you, even if it is miles away, and the graphite rods most of us use nowadays make great lightning conductors! No fish is worth dying for. ( More about this in Fishing can be Hazardous to your Health)

If the conditions over the last few days have been unstable or there is a cold front passing through, the Bass are more likely to be tucked in very tight to cover, such as under logs, undercut banks, tree stumps, etc. and buried right inside weedbeds.

Fish will sit and sulk and will not be too interested in eating. However, they can still be caught with a slow falling, natural looking bait carefully placed very close to them, so they don't have to work for it. We like to use either unweighted or very lightly weighted Black Mamba® bait. Choose which bait to use, based on the water clarity and the size and  colour of baitfish the Bass are most likely to be eating.

Be patient and just let the bait flutter down, looking for all the world like a dying baitfish and even the most hook shy fish will move out of his cover to just suck it in. If you have the patience to fish the baits slowly and methodically like this, you can have spectacular days when the other guys can't buy a fish!

When it is sunny, Bass will tuck into the shadows. They will be under overhanging trees and bushes, lily pads, under logs and tucked into weeds. In these conditions, most anglers use baits that will fall vertically and cast them close to the cover. Baits such as tubes, jig and pig, jig and craws, craws, worms and lizards are often used.

The problem with these baits is that everyone uses them. The Bass have often seen them dozens of times before and because they know the UPC codes off by heart, are often reluctant to bite them. Also, these baits are usually weighted to the point where they drop like a stone to get through the cover. This is a very unnatural presentation as nothing in nature plummets!

A Black Mamba® bait is very hard to beat when fish are finnicky or tucked in tight to cover. Its slow seductive, gliding action draws reaction strikes when nothing else will work. If you are fishing in relatively open cover and/or in water up to six feet deep, use no weight at all. If you are fishing deeper, use the lightest weight you can get away with, for the conditions. It is vitally important to remember, that it is the slow, gliding fall which triggers the fish to bite, so do not weigh the bait down too much.

By letting the bait sink slowly, you present an unbelievably natural looking target for the fish. These baits sink exactly like a real baitfish would, and the fish cannot resist it. After waiting up to a minute, you will often see your line swimming off. SET THE HOOK because a fish has the bait in its mouth.

When you are faced with low light conditions such as when it is overcast or early in the morning or in the evening, when the sun is low in the sky, Bass will be roaming around in the open, actively looking for food.

In these conditions, you want to use a fast, horizontal 'search' bait such as a spinnerbait, crankbait or better yet, a Black Mamba® soft-plastic jerkbait. In most conditions, we use a natural coloured Slick Willy® or Wild Willy® in clear water or a Ribbed Willy® if the water is murky.

Especially when you are fishing shallow in clear water, you'd better believe that the fish get a good look at a bait before they strike. Most other lures have negative cues; something which tells the fish that they are not real food. Fish can quickly become conditioned to these negative cues and refuse to bite the bait.

The Black Mamba® baits have nothing about them that tells the fish they are not real food, so fish are much more willing to bite them. The natural, baitfish profile and random gliding motion of the Black Mamba® baits, draw all-caution-to-the-wind, heartstopping, explosive surface strikes when the Bass will completely ignore spinnerbaits and crankbaits. These baits are not for the faint of heart!

Strategy for Locating Bass

Spring- Largemouth spawn in shallow bays with a hard bottom. They only spawn once a year, in the Spring, so you can bet it's a very important time of the year to them. If you only got lucky once a year, it would be important to you too!

They will hang around for a short while after spawning, as there is an abundant food supply of baitfish species which spawn in the same areas. As the water warms, the Bass and their forage will move out into the weedflats adjacent to the spawning areas. The bigger, female fish are always the first to leave.

We recommend that you start shallow, in a spawning bay, then move out towards deeper water. The bigger the spawning bay, the larger the population of fish it should hold. It is not unusual for Bass to change locations throughout the day, the season or because of changing weather conditions. Many inexperienced fishermen will always pound the bank for Bass, regardless of conditions, and are often dissappointed. You can't catch fish if they are not there. Also, the shallow dwelling fish have seen every fishing lure imaginable, because of the popularity of fishing the banks, and are very reluctant to bite.

Summer- As the Largemouth leave their spawning areas, they will tend to move along the shoreline and structure attached to it. They usually will move out into the weedflats adjacent to the spawning areas. They will not just swim off into the main lake.

Therefore, if the Bass aren't in the shallows, you move out to the first drop in depth and search until you locate fish. Pay attention to the points and any available cover at both  sides of the mouth of the bay, as fish will often congregate there. Bass are really drawn to edges and so your search should be concentrated on the edges of the weeds where they drop off or die out.

Fish will also be buried in the weeds. However, they are usually spread out all over the place and are therefore, harder to find. Dunk your bait in holes in the weeds and jig it up and down a couple of times. If nothing bites, move on. Target the holes because there is usually a reason why there is a hole; change of bottom, a rock, a stump etc. These changes are often where fish will congregate and are therefore, high percentage spots, that is, spots where you are much more likely to get bitten.

Fall- As the water starts to cool in the Fall, the Bass are going to begin a slow migration towards deeper water in preparation for Winter. They are usually found at the deeper edge of the weedflats they lived in throughout the Summer. As the Fall progresses and the water temperature drops, they will will move closer to their deep-water wintering holes and start to bunch up. Bass feed aggressively throughout the Fall period so that they can build up fat reserves which will see them through the Winter. We catch most of our biggest fish in mid to late fall and we often have the lake to ourselves.

On Indian Summer days, the Bass and their prey, will often move shallow to take advantage of the brief warming trend. Even a rise of a few degrees, can make a huge difference, at this time of year.

As Winter approaches, Largemouth will move into the nearest, suitable, deep water in the area, usually seeking a depth of 15 to 30 feet, where the conditions are more stable, to spend the Winter. They will often school in large numbers and remain in a state of near hibernation until the water starts to warm again in Spring. If you can find any green weedclumps, they are often stuffed with fish. Fish very slowly and methodically with a lightly weighted Atomic Wedgie®.
