Albino Catfish 4-6"
Channel catfish possess very keen senses of smell and taste. The olfactory pits of their nostrils (nares) are very sensitive odor sensing organs with a very high concentration of olfactory receptors. In channel catfish, these organs are sensitive enough to detect several amino acids at about one part per 100 million in water. In addition, the channel catfish has taste buds distributed over the surface of its entire body. These buds are especially concentrated on the fish's four pair of barbels (whiskers) surrounding the mouth — about 25 buds per square millimeter. This combination of exceptional senses of taste and smell allows the channel catfish to find food in dark, stained, or muddy water with relative ease. Channel catfish also possess a Weberian apparatus, which amplifies sound waves that would otherwise not be perceivable.
