Barkoh. 0000009693 00000 n 0000005185 00000 n Range. A substance that provides both nutrients and energy to a living thing. Blue catfish are highly productive and create high numbers of offspring each reproductive cycle. They use a vigorous sweeping motion with their tails to clear debris and use their jaws to remove larger objects; their nests can range from 6 to 14 inches in diameter. Blue catfish have the ability to taste their surroundings with sensory tissues on their barbels and certain areas on their skin; they utilize these sensory devices to search for food. Although blue catfish prefer freshwater, in rare situations they can occur in brackish estuaries with salinities below 12%, and can tolerate salinities up to 22 ppt (parts per thousand). Recognized for their large bodies that can weigh up to 100 pounds (45kg), blue catfish can reach two to five feet in length (600 to 1500mm).
