The Science of Bass Fishing
Wouldn’t you know it? Even fishing isn’t safe from the scientists anymore. But what you might not know is that it never was. Before you turn off your computer and say a scientist would not know anything about catching a good old bass, give it a chance. You might just learn something. Besides, some of the best anglers in the world study the science of their prey before they attempt to catch it.
First we will address the issue of climate and/or temperature. This is essential knowledge here, so pay close attention. All fish are water temperature sensitive, but perhaps Bass are more than any other. Your typical Largemouth Bass has an optimum temperature preference of roughly 80 degrees. Seems hot, doesn’t it? Keep in mind, though, that a largemouth can survive, not thrive, in waters all the way up to the mid-nineties! But, regardless, 80 is the temperature where they reach peak performance. They are faster, more aggressive, and grow at a better rate at this temperature. Of course, they do bite at lower temperatures, and the water rarely ever reaches 80, but if it does, then that is the day to get up early in the morning and hit the lake. There will be a mist over the water at that point, and this is always a good sign at daybreak that the Bass will be hitting hard. If the water reaches temps less than 50 degrees, you can expect little or no feeding activity at all, and they will not increase in size at all in these low points. This is due to the fact that digestion occurs six times faster at 77 degrees that at 44. If the food does not digest, the fish do not need to feed and they don’t grow.
Spotted bass, on the other hand, peak out at about 75 degrees, which makes them the better biters. Smallmouth Bass prefer the 70-degree area, which beats out the Spotted and the largemouth hands down, though they are a bit harder to locate in this part of the country. But trust me, they are out there. It’s just a matter of knowing the right spots.
Next we will cover spawning, another major aspect in the catching of Bass. Smallmouth Bass will begin spawning in the early to mid-Spring when the temps clime to 60 degrees. These are your early spawners. Largemouths get in the mood a few degrees warmer, between 64 and 66 degrees. Studies by freshwater marine biologists have determined that Largemouths feel the instinctive urge to build nests at lower water temperatures than when the females are ready to lay eggs. Think of it as a courting ritual. The males will build the nests at 54-57 degrees. After the nests are built they will hang around them until a female comes along when the water reaches 60 degrees. She checks the male out, then the nest, and then it is on if all is acceptable. Not that different from you and I.
The areas of spawning are many, but they do have to meet certain criteria for the male Bass to move in. They can spawn in lakes, rivers, or even ascend tributaries. If your fishing in a tributary during the ideal temperatures, you would want to go to the upper end as the Bass will travel upstream during heavy spring rains and rising water levels. But the common things that your typical Bass will insist upon are shallow spots with dark bottoms and they must be protected from wind and current. If you know that one special place that has a shallow bottom with dark mud or silt and has a wall or bluff keeping the wind off, then that is the magic spot for your breeding bass.
For all you river fishermen out there, when the water reaches 60 degrees don’t expect too much from moving water. Both wind and moving water can cause fluctuating temps, wash the eggs away, and silt can gather suffocating the young eggs.
Take these little science tidbits into consideration fellow fishermen. You never know what you’ll bring up. Good Luck and Good Fishing!
