Channel Catfish (ictalurus punctatus) are a fast growing game fish that will do well in most ponds and lakes. Body color varies from silvery-gray on the top to light on the underside, depending mostly on the clarity of the water. They put up a good fight, make a great meal, and are the most popular fish in the world for stocking. Our recommendation for stocking rate is 100 per acre and restock every 2 years due to low reproduction. Catfish are omnivores so their diet ranges from tiny algae and insects to smaller fish in a pond.
