Blue Catfish

(Ictalurus furcatus)





The blue catfish is one of the largest species of freshwater fish in North America. Only the alligator gar and a few species of sturgeon get larger.



Description

Blue catfish have a deeply forked tail and light gray or silver colored body. They get their name from the blue overcast to their body most obvious on the top of their head and down their back. Blue catfish differ from the very similar Channel Catfish by having a longer anal fin (30-36 rays compared to 24-30 on a channel catfish) with a straight bottom edge, as opposed to a rounded bottom edge. Also, blue catfish never have black spots on their body like those on young channel catfish.

Habitat and Habits

Blue catfish are found in very large rivers and typically feed in areas with relatively swift currents. In Ohio they are found in the Ohio River and the lower portion of its larger tributaries. They are most common in the Ohio River from Portsmouth down stream to Cincinnati.

Reproduction and Care of the Young

Blue catfish spawn in late spring or early summer. Males choose a nest site in or under hollow logs or large holes under the bank. The nest is then guarded by the male until the eggs hatch.
