The green channel catfish is a type of channel catfish that is greenish in color and has a yellow tail, a yellow-tailed channel catfish.

The channel catfish is a collective name for four species of channel catfish, including the fine-scaled channel catfish, yellow-tailed channel catfish, round-nosed channel catfish, and silver channel catfish, which belongs to the order Cypriniformes, family Cyprinidae, subfamily Channel Catfish, and genus Channel Catfish. The yellowtail channel catfish is a specialty of the Dongting Lake system in Hunan Province. Because the fins and tail of this fish are greenish-yellow and orange, and the specification is usually around 500 grams, the local name in Hunan is yellow board diao.

The channel catfish prefers to live in the middle and lower levels of wider waters such as rivers, streams and lakes. Silver catfish and fine-scaled channel catfish live in the middle and lower reaches of rivers, while round-nosed catfish live in the middle and upper reaches of rivers.

The channel catfish is adapted to living in running water. It often scrapes its food, mainly diatoms, followed by filamentous green algae, cyanobacteria, bacteria and plant debris, with the more developed horny edges of its jaws on the surface of rocks or mud, and feeds with high intensity and frequency throughout the year. They are found in all major river basins in China, and the common ones are silver catfish, fine-scaled channel catfish, round-nosed catfish and yellowtail catfish, all of which are large.

The subfamily of channel catfish is largely identical in appearance, with a laterally compressed body, a rounded abdomen, some with a ventral rib between the ventral fin and the anus, a small head, and an obtuse muzzle. The mouth is inferior or nearly anterior, with a flat transverse fissure. Mandibles with sharp angular margins, no mouth whiskers. Body rounded scales. Dorsal fin with smooth hard spines, branched fins 7 to 9 branches, mostly 7. Dorsum gray-black, abdomen silvery-white.

Expanded Information

The channel catfish is extremely fast-growing, spawns in clusters, and naturally proliferates quickly. The channel catfish is a wild fish in its own right, and because of the abundant bait, the fish grows quickly, reaching 100-150 grams by the end of the year for hatchery fry, and typically reaching about 500 grams the following year.

This fish is sexually mature in the second winter year, and generally carries 200,000 eggs/kg. In May-June each year, when the water temperature rises to 20-26C, under the impact of the current, the gonadal mature male and female channel catfish can naturally spawn in clusters in the area of running water, which is an extremely spectacular scene.
