Pictures of Flathead Catfish Drawing -

The flathead catfish grows to a length of 155 cm (61 in) and may weigh up to 56 kg (123 lb), making it the second-largest North American catfish (after the blue catfish, Ictalurus furcatus). The average length is about 25-46 in (64-117 cm). Its maximum recorded lifespan is 24 years. Males are mature from 16 cm (6. 3 in) and 4 years of age, while females mature from 18 cm (7. 1 in) and 5 years of age, but may mature as late as 10 years. [citation needed] The world angling record flathead catfish was caught May 14, 1998, from Elk City Reservoir, Kansas, and weighed 123 lb 9 oz (56. 0 kg). However, a record from 1982, caught by "other methods", shows that the flathead catfish would be North Americas longest species of catfish, after a specimen pulled from the Arkansas river measured 175 cm (69 in. ) and weighed 63. 45 kg (139 lbs and 14oz. ).
