The water temperature is important in bass fishing because it affects their metabolism. Their metabolism goes up when the water is warmer and they eat more. Temperatures between 60-75 degrees cause them to be more active and biologists note that it is their favorite temperature.
The middle to high 70's spurs them to be active 15 hours per day, while spikes above the 80's gives them the slows, their activity dropping to 8 or less hours per day at 85 degrees, and 90 degrees drops their active hours to a low of 4.
When the water is colder bass won't chase a lure very far. They might not chase at all. They'll opt for smaller tidbits of food. This information is essential to bass fishing in the winter and relates to fishing in most regions of the U.S.
When the temperature drops below 50 degrees their metabolism slows and they don't bite as much. They are less sluggish when the temperature rises to the mid 50's and up. Then they swim from the deeper to shallower waters to participant in spawning. In the earlier part of the season fish the warmest parts of the lake. When the temperature reaches the lower 50's to middle 50's and if clarity is good look for the bass in the channels at 10-15 feet deep.
After the spawning time, fish parts of the lake that warm up later. Fishing spots with good action in the spring are slower in the summer. Bass are at their most sluggish in the winter; the key is to find deeper water where the temperature is a few degrees higher than other areas.
As the temperature increases, the dissolved oxygen or saturation level decreases. When the temperature increases the bass consume more oxygen, but the oxygen in the water is decreasing, which causes stress to the bass.
This oxygen heat relationship is important to consider when, you're trying to keep the oxygen level up in your livewell so your bass have enough oxygen. If you keep your livewell at 75-80 degrees the bass well use less oxygen and your livewell will produce more oxygen. The bass have a better chance of survival.
To control your oxygen level, aerate. To control water temperature
add water when the temperature falls below 75 degrees and add ice when the temperature rises above 75 degrees.
The survival of the bass is part of the bass fishing tournament because they practice catch and release. This lets more fish reproduce and the bass are plentiful. The handling of the bass and the water temperature determine their survival rate. When the temperature is below 65 degrees 94% percent of the released bass live. Thus, fall, spring, and winter tournaments are less detrimental to bass survival. Conversely, only 61% of the fish live after release if the temperature is 80 degrees or higher.
Now that you're armed for bass fishing with temperature intelligence, you can use it to fish your hottest fishing trips yet.
