Spawning Habits - Spawning occurs mostly in rivers and streams in the spring and early summer when waters warm to 70 to 85 degrees. They also will spawn in larger lakes where suitable habitat is available. Eggs are deposited in nests secluded under banks or logs or over open bottom. The male selects the site, often a natural cavern or hole, clears the nest and guards the eggs and young. A female may lay 2,000 to 21,000 eggs that hatch in six to 10 days depending on water temperature.
Males protect the fry until they leave the nest in about a week.
Feeding Habits - Feeds primarily at night using taste buds in the sensitive barbels and throughout the skin to locate prey. Although they normally feed on the bottom, channels also will feed at the surface and at mid-depth. Major foods are aquatic insects, crayfish, mollusks, crustaceans and fishes. Small channels consume invertebrates, but larger ones may eat fish. Contrary to popular belief, carrion is not their normal food.
