The blue catfish, Ictalurus furcatus, is one of the largest species of North American catfish, reaching a length of 165 cm (65 in) and a weight of 68 kg (150 lb). The average length is about 25-46 inches (64-117 cm). Blue catfish are distributed primarily in the Mississippi River drainage, including the Missouri, Ohio, Tennessee, and Arkansas Rivers. Blue catfish tend to favor deeper water in larger rivers and reservoirs, but will make feeding and spawning forays into relatively shallow water. Blue catfish can be frequently caught in warmer climates in water as shallow as 12 in. Blue catfish are incredible fighters, and are often considered game fish due to their reputation for attacking anything.
