Understand the Thermocline and How It Effects Fishing

Many lakes will develop a thermocline during the hot summer. A thermocline develops when layers of water seperate into several layers and the lowest level of water in the lakes is full of rotted decaying matter which also depletes of oxygen.

Because this bottom layer of water is depleted of oxygen bait fish like gizzard shad and threadfin shad and the other fish cannot survive below the thermocline. This has some dramatic effects on all the species of fish and has significant effects on catfishing.

In this video we walk you step by step through understanding what a thermocline is, why it develops and exactly how it effects fishing for all species of fish and especially catfishing with a thermocline.

if your fishing in a lake in the summer and not catching fish, fishing below the thermocline very well could be why.
