Answer:

Our major catfish species spawn during spring or summer when the water warms to an optimal temperature. Channel and blue catfish spawn at 70-84 degrees, but 80-81 degrees is considered best. Flatheads spawn at 66-75 degrees. Catfish spawning begins at different times in different latitudes, progressing from south to north.
