Lake Texoma Fish Species: Blue Catfish The blue catfish is the largest freshwater sportfish in Texas. Where mature populations exist, 50-pounders are not unusual. Typically, the largest fish are caught by trotliners, some of whom have landed specimens in excess of 115 pounds. Rod-and-reel anglers have anded specimens in excess of 80 pounds. Catfish is the second most preferred group of fish among licensed Texas anglers, and blues rank third behind channel and flathead catfish. Like the channel cat, the blue catfish is considered an excellent food fish. Other Names: Channel Cat, Hump-Back Blue; Ictalurus is Greek meaning “fish cat,” and furcatus.
