On average each female flathead lays a clutch of roughly 100,000 eggs. The role of the male catfish in fanning the clutch is to provide oxygen to the eggs through the use of his fins. The spawning of these catfish occurs when the temperature reaches roughly 66 to 75 °F (19 to 24 °C) and the flow of the stream or river becomes steady.
They eat insects, leeches, snails, fish, clams, and many plants. They are also known to eat corn, which can be used as bait. Similarly to other catfish, they spawn only after the temperature of the water has reached 80 °F (27 °C) in June and July. However, cooler temperatures are required before brown bullheads will spawn in the northern US.
