BLUE CATFISH ((Ictalurus furcatus) forked-tailed cat, humpback blue, chucklehead)
◎Heavy-bodied with a wide head and high spot forward of center near the head called the dorsal hump. Upper jaw projects well beyond the lower. Bluish-gray body above, fading to white on sides and belly. No spots and a deeply forked tail. Smaller blue cats are often confused with channel catfish. Blue cats are often confused with channel catfish. Small channel cats typically will have spots lacking in small blue cats. However, large channel cats and medium-sized blue cats can be more difficult to tell apart, often having similar coloration and general body shape. The margin, or edge, of the anal fin can be used to identify these fish; blue cats have an anal fin with a very straight margin, in channel cats the anal fin has a rounded margin. Biologists and anglers can definitively distinguish between the two species by counting anal fin rays;30-35 rays on the blue catıs anal fin verses the channel catıs 25 to 29 rays.
CHANNEL CATFISH ((Ictalurus punctatus) spotted catfish, speckled catfish, silver catfish, fork-tailed catfish)
◎Deeply forked tail. Upper jaw is longer than, and overlaps the lower. When small, its smooth-skinned body is usually spotted; however, these spots disappear in older fish (can be confused with blues catfish, see identification of blue catfish). Has a small dorsal fin with stiff spine standing high on its back. It has eight barbels, or feelers, four located under the lower jaw, two on top and one at each end of the upper jaw. Barbels contain taste buds, which help it find food. Varies in color, although generally dark brownish to slate-gray on top, fading to light brownish-gray on the sides. Has 25 to 29 rays on its anal fin.
FLATHEAD CATFISH ((Pylodictis olivaris) mud cat, shovelhead cat, yellow cat)
