When monster blue cats are landed, there is no mistaking which species they are but when smaller individuals are caught, identification is not as obvious.
Blue catfish are similar in appearance to channel catfish, however young blue catfish do not exhibit the “freckled” coloration that is characteristic of young channel catfish.
Another identifying feature is the anal fin. The edge of the anal fin of the blue catfish forms a straight line and is longer than that of channel catfish, which is curved.
Both species are caught in rivers and lakes throughout much of North America.
