The blue catfish (Ictalurus furcatus) is 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). The fish can live to 20 years. The native distribution of blue catfish was primarily in the Mississippi River drainage, including the Missouri, Ohio, Tennessee, and Arkansas Rivers, and the Rio Grande, and south along the Gulf Coast to Belize and Guatemala. .[2] These large catfish have also been introduced in a number of reservoirs and rivers, notably the Santee Cooper lakes of Lake Marion and Lake Moultrie in South Carolina, the James River in Virginia, Powerton Lake in Pekin, Illinois, and Springfield Lake in Springfield, Illinois. This fish is also found in some lakes in Florida.[3] The fish is considered an invasive pest in some areas, particularly the Chesapeake Bay. Blue catfish can tolerate brackish water, thus can colonize along inland waterways of coastal regions.[4]
Record-setting fish
On June 18, 2011, Nick Anderson of Greenville, NC reeled in a 143-pound blue catfish. The fish was caught in John Kerr Reservoir, more commonly known as Buggs Island Lake, on the Virginia-North Carolina border. On June 22, 2011, the Virginia Dept of Game and Inland Fisheries certified the blue catfish as the state's largest, setting a new state record.[5] The fish had a length of 57 inches (145 cm) and a massive girth of 47 inches (120 cm).
On February 7, 2012, a 136-lb blue catfish was caught on a commercial fishing trot line in Lake Moultrie, one of the two Santee Cooper lakes, near Cross, South Carolina. It was 56 inches long. The fish is the largest blue catfish ever weighed on a certified scale in South Carolina, but it is not eligible for state record certification because it was not caught on a rod and reel.
On July 20, 2010, a yet to be certified new world record blue catfish was caught by Greg Bernal of Florissant, Missouri, on the Missouri River. Greg's girlfriend, Janet Momphard, a nurse from St. Charles, helped land the world-record fish. The record catfish weighed in at 130 lbs. It was 57 inches long and 45 inches in girth. The previous angling world record, 124 lb, was caught by Tim Pruitt on May 22, 2005, in the Mississippi River.[6][7] This record broke the previous blue catfish record of 121.5 Lbs caught from Lake Texoma, Texas.
The Indiana record for a blue catfish was set in 1999 by Bruce Midkiff. The fish was caught in the Ohio River and weighed in at 104 pounds.[8]
Diet
Blue catfish are opportunistic predators and will eat any species of fish they can catch, along with crawfish, freshwater mussels, frogs, and other readily available aquatic food sources; some blue catfish have reportedly attacked scuba divers in the Mississippi River. Catching their prey becomes all the more easy if it is already wounded or dead, and blue cats are noted for feeding beneath marauding schools of striped bass in open water in reservoirs or feeding on wounded baitfish that have been washed through dam spillways or power generation turbines.
Invasive
The ability of the blue catfish to tolerate of a wide range of climates and brackish water has allowed it to thrive in Virginia's rivers, lakes, tributaries, and the Chesapeake Bay. Unfortunately, the relatively low mortality rate, large body size, wide range of species preyed upon, and success as a predator has resulted in the blue catfish being considered a problematic invasive species in Virginia. Since their introduction in Virginia waters in the 1970s,[9] blue catfish populations have exploded. Recent electrofishing studies have presented data suggesting blue catfish make up around 75% of the total fish biomass in the James River.[10] The introduction of blue catfish in the James River has begun to have an impact on several species native to the James, such as the smallmouth bass, which is a native predator in the James River that is greatly outcompeted by the blue catfish for the same food sources. In addition to outcompeting the smallmouth bass for food, the blue catfish also heavily preys on the smallmouth bass.
