Wiki - Did you know?
The channel catfish (Ictalurus punctatus), known informally as the "channel cat", is a species of catfish native to North America. They are North America's most abundant catfish species. The channel catfish appears to be a rather old species that has persisted for nearly 20 million years, as fossil remains assigned to it are abundant in numerous geological formations of central North America from the Miocene onwards.
An average adult channel catfish measures at least 12 inches (30 centimeters) long, and weighs between 2 and 4 pounds. The largest specimen on record weighed 58 pounds (26.3 Kg) and was caught in 1964 by an angler in South Carolina.
Adult channel catfish, over 45 centimetres (18 in), prey on fishes such as yellow perch and sunfish. The diet of adults consists of snails, clams, crustaceans (such as crayfish), snakes, frogs, small fish, insects, aquatic plants, algae, seeds, grains, nuts, and occasionally even small birds and small mammals. Younger channel catfish are more consistently omnivorous, eating a large variety of plants and animals
All species of catfishes can generate sound through stridulation, and many can produce sounds through drumming.[28] Stridulation consists of the clicking or grinding of bony parts on the fish's pectoral fins and pectoral girdle, and drumming consists of the contraction of specialized sonic muscles with subsequent reverberation through the swim bladder.
Channel catfish have a well developed sense of smell and taste. Their nostril pits (nares) contain sense organs with high concentrations of olfactory receptors.[15] In channel catfish, these organs are sensitive enough to detect several amino acids at about one part per 100 million in water. Also, the channel catfish has taste buds distributed over the surface of its entire body. These buds are especially concentrated on the four pairs of barbels (whiskers) surrounding the mouth, which have about 25 buds per square millimeter. This combination of strong senses of taste and smell allows the channel catfish to find food in dark, stained, or muddy water with relative ease.
