An average adult channel catfish measures at least 12 inches (30 centimeters) long, and weighs between 2 and 4 pounds. The largest specimen on record weighed 58 pounds and was caught in 1964 by an angler in South Carolina. [16] As channel catfish grow longer, their weight increases. The relationship between length and weight is not linear.

The maximum length is 160 cm (5.2 ft) in the blue catfish and the flathead catfish. [5] The bullheads, though, are small catfish which at maturity often weigh less than 0.5 kg (1 lb), while the madtoms (genus Noturus ) are in general much smaller.
The ratio of ovary weight to adjusted body weight (GSI) increased in females in fall and spring, with greater rates of growth in mature adults. [7] Slender madtom are usually 3 inches (7.6 cm) or less in size with a maximum of about 4 inches (10 cm). [ 10 ]
The blue catfish (Ictalurus furcatus) is a large species of North American catfish, reaching a length of 65 in (170 cm) and a weight of 143 lb (65 kg). [4] The continent 's largest catfish, it can live to 20 years, with a typical fish being between 25–46 in (64–117 cm) and 30–70 lb (14–32 kg).

Standard weight equation for largemouth bass [1] and burbot [2] (fish). Standard weight in fish is the typical or expected weight at a given total length for a specific species of fish. Most standard weight equations are for freshwater fish species. Weight-length curves are developed by weighing and measuring samples of fish from the population.
Saugers feed on a variety of invertebrates and small fishes depending on the time of year and size of the sauger. Channel catfish Ictalurus punctatus and freshwater drum Aplodinotus grunniens are midsize (300–379 mm) and large (>379 mm) saugers' main food source during spring. The diet of a small sauger (200–299 mm) is slightly different ...
