Finding the comfort zone for bass when temperatures are in the 40’ and 50’s goes a long way toward catching these early season bass. Not all fish are doing the same thing at the same time.
A bass’s metabolism slows during this time. They concentrate in deeper areas just off the weed lines waiting for an opportunity to catch shad. During the colder days bass seek deeper water. They try to find the best comfort level available.
As the water begins to warm it is recommended that you begin to work back into feeder creeks, secondary points and flats found there. Cast into the flooded willow bushes.
With the varying water temperatures fish may be doing different things. The difference in temperature can be as much as 10 degrees between different areas on the same body of water.
Preferred lures include crankbaits as well as black/blue jigs, a jig and pig or a spinnerbait.
Many areas experience the passing of multiple cold fronts this time of year. Bass are most affected by cold fronts in the spring. Big swings in the weather affect the fishing action dramatically.
Another aspect of early season bass fishing is changing water levels. Generally water levels rise as winter snows melt. Stay away from muddy water and look for water with good visibility from the surface down 15-inches. Bass will feed all the way up to a few inches of the shore line. As long as their backs are still in the water they continue to feed.
During times when casting to these shallow fish is necessary, spinner baits and buzz baits are best. They simulate food sources. If there is no brush present, a spinnerbait rides higher and can be fished more slowly. Buzz baits can be cast past structure and brought through it into the strike zone of the bass. If the bass are active, as in late spring, they will follow the bait until they catch it.
In colder areas temperatures under ice is usually 35 to 38 degrees F. Big bass forage for food they will soon need to invest their energy into reproduction. Smaller more immature bass are not going to invest energy into reproduction. They are investing energy into growth.
Water temperatures increase as the air temperatures rise. A temperature increase is followed by a metabolic increase and then anglers find more fish biting. The bite increases until point where the bite remains constant and they begin to spawn. As fish get into that spawning period there is another big peak in activity.
What bass do is lake by lake dependant. What really drives how deep they are and how they position themselves in the water column is dependant upon the forage base.
The two most important things to a fish are reproduction and eating. Most likely fish are always sort of positioning themselves where they are going to maximize odds either to reproduce or to eat.
Cold water bass are usually associated with the shad. In the spring time they are going to be up in the shallows where they are going to maximize their chance of reproducing.
Basically a fish is going to maximize how much food it puts in its mouth while it minimizes the time and energy expended to capture it. Fisheries biologists call this the “optimal foraging theory.”
The key is efficiency. Because their movements are lake by lake dependant they may be feeding on shad, crayfish, bluegill or something else. By knowing the forage species favorite of the day, one knows where they are to be found.
Water levels can also determine where the angler should begin fishing. If the water is high, the brush along the shore is a good place to begin. If it is low, chances are the fish will be on the main and secondary points.
Water clarity is an important factor. As long as there is sunlight penetration, vegetation dies back but is never completely eliminated. Winter water appears to be clearer because there is not much action by any of the aquatic life. As water temperatures warms, phytoplankton, zooplankton, all the suspended solids are stirred up. In winter everything slows down. With all the suspended solids settling out, the water clears.
The site feeding bass appear to become more efficient as they are more able to see the shad in clearer water.
The most effective bait at any time of the year is one that matches the forage. The season does not matter. Figure out what the bass are eating and throw a lure that mimics it.
In one area a shad imitation might produce more strikes than bright colors. A sort of general rule is that black and the natural colors out perform all the fancy colors. Winter a great time to throw natural looking baits. As long as you have water clarity, go with the natural stuff. You more closely mimic the prey item of choice.
What an angler really needs to be aware of is the metabolism of bass. A decline in their metabolism and they do not eat. They do not need as much food to carry out life demands. When their movement is minimized not as many fish will be caught. Not unless you hit that perfect day.
A perfect day is when all the aquatic life forms are feeding. With lower metabolism consumption is down. You have fewer bites and will probably have to stick it out a little bit longer. Just because you go out there and make 50 casts on one rocky point does not necessarily mean that you quit fishing. If the spot was hot in the past or last fall go ahead and continue to fish them.
Eventually you find a fish or multiple fish that are willing to bite.
Every bass wants to eat and reproduce. If you can get in between them and what they are eating or where there they are reproducing you catch fish. If the shad are set up on structure, then absolutely structure is important. If the shad are not on structure then the bass are not going to be on structure.
Bass are most likely to suspend in the winter. They are close to schooling gizzard shad. Think about all the power cooling lakes. Where are all the gizzard shad? They are right in that warm water discharge and the bass are right behind them.
Gizzard shad seek the warmer water because they are trying to survive. Gizzard and Threadfin shad are pretty wimpy. The winter time for shad is tough. They try to maximize their survival by finding warmer water temperatures.
Forage fish school as a defense mechanism. The primary goal of any schooling fish is finding safety in numbers.
During substantial cold snaps in winter anglers need to seek a warming trend. You will see maybe one day within a week that is going to get 60 degree air temperatures and all the rest of the days are in the 30′s and 40′s.
If it is cold in the morning go out fishing later. Warming periods allow the sun to penetrate the water in the shallows. The forage fish go up in there to seek refuge. Bass notice and follow them. It is perfect opportunity to find bass really shallow.
Small jigs produce bites during these periods. When you have a fish that has low metabolism you do not need to be throwing a 12-inch crankbait. Try a 2-inch crankbait, throw something small. Use something that has a lot of flash, but small. Make sure that you are working the lure slowly. Never burn a lure like you might do in summer.
During a warming trend, if the fish are not biting in the morning, go back in the afternoon and catch lots of fish.
