Despite the names white catfish and blue catfish, any of the species with a forked tail maybe light silvery blue with a white belly, though in the white catfish there is sometimes a sharper contrast between the bluish back and the white of the body. It usually has numerous dark spots on the body, except in older individuals and spawning males.The surest way to identify the white catfish is to count the rays in the anal fin. The white catfish has 19-23 rays and the fin is rounded along the bottom edge. The channel catfish has 24-30 rays and also has a rounded anal fin. The blue catfish has a longer and much straighter edged anal fin with 30-36 rays.
