[35] In the United States, catfish is the largest aquaculture industry, and channel catfish make up 90% of farm-raised catfish.

The common name, hardhead catfish, is derived from the presence of a hard, bony plate extending rearward toward the dorsal fin from a line between the catfish's eyes. [4] It is an elongated marine catfish that reaches up to 28 in (70 cm) in length and 12 lb (5.5 kg) in weight. [ 5 ]
The largest recorded weight for a gafftopsail catfish is 4.54 kg (10.0 lb) [4] and 69 cm (27 in) in length. [5] A more common weight and length of gafftopsails caught is 1–2 lb (450–910 g) and 12–16 in (30–41 cm). As gafftopsail catfish grow longer, they increase in weight, but the relationship is not linear.

The wels catfish has also been observed taking advantage of large die-offs of Asian clams to feed on the dead clams at the surface of the water during the daytime. This opportunistic feeding highlights the adaptability of the wels catfish to new food sources, since the species is mainly a nocturnal bottom-feeder. [22]
In Africa, this catfish has been reported as being second in size only to the vundu of the Zambesian waters, [4] although FishBase suggests the African sharptooth catfish surpasses that species in both maximum length and weight. [5] [6] C. gariepinus has an average adult length of 1–1.5 m (3 ft 3 in – 4 ft 11 in).
