Blue / Forktail Catfish
name: Blue / Forktail Catfish
other names: Channel Cat, Hump-Back Blue, Fork Tail Cat, Great Blue Cat, Silver Cat, Chucklehead Cat, Blue Fulton
They resemble channel catfish by having deeply forked tails, but are dissimilar because they are unspotted and have a long, straight-edged anal fin with 30 to 35 rays. Adult fish have stout bodies with prominently humped backs in front of the dorsal fin. The back and upper sides are blue to slate gray, and the lower sides and belly are white. The internal air bladder has a constriction in the middle, giving it a two-chambered appearance, hence while these fish grunt when out of water.
Blues occur in big rivers and in the lower reaches of major tributaries. They prefer clearer, swifter water than other catfish, and are usually found over sand, gravel or rock bottoms. They can also be found in billabongs left over each year from the wet season.
Young blues eat aquatic insects and small fish while larger blues prefer crayfish, mussels and other fish. They feed primarily at night.
Blue catfish grow faster and live longer than channel catfish. They are the largest member of the catfish family. Blues may grow to lengths of over 55 inches and may weigh more than 100 pounds. Maximum life span for blues is unknown but is probably 20-25 years.
One of the strongest freshwater fish, blues are caught on bush hooks or trot lines as well as rod and reel. The most effective baits are cut fish, live fish and night crawlers. They also will take prepared and rotting baits. Most are caught while bottom fishing with cut fish, rigged on large hooks weighted down by heavy leads.
