One of the reasons catfish can be found all over the world is because they can adapt to a wide variety of habitats. Catfish can be found in areas where the temperature is 95f (35c) and they can also survive at temperatures just above freezing. Typically when the water temperatures gets below 65f (18) catfish will slow down, conserve energy and may halt feeding, but hey have been known to be active year round even in cold temps.
