Blue Catfish

---

The blue catfish (Ictalurus furcatus) is a large freshwater fish native to the Mississippi, Missouri, and Ohio River basins in North America. This species has a bluish-gray body, a deeply forked tail, and smooth, scaleless skin. Like other catfish, it has long barbels around its mouth that help detect food in murky waters. It is the largest species of North American catfish, capable of growing over 5 feet long and weighing more than 100 pounds. Blue catfish are opportunistic feeders, consuming fish, crustaceans, mollusks, and even plant material. Larger individuals are known to be apex predators in their ecosystems. They prefer deep, slow-moving waters with sandy or muddy bottoms, thriving in large rivers, reservoirs, and lakes. Blue catfish reproduce in late spring to early summer, with males creating nests in secluded areas and guarding the eggs until they hatch. These fish have been introduced to regions outside of their native range, including the Chesapeake Bay where they have become invasive, outcompeting native species. Due to their size and strength, they are highly prized in recreational fishing and are also harvested for commercial consumption.

Fun fact: The oldest blue catfish was recorded to be 25 years old!
