What kind of fish is Qingjiang fish? Origin and characteristics explained in one go

Qingjiang fish refers to fish produced in the Qingjiang reservoir area of Hubei, praised as a top aquatic product of Hubei, the "province of a thousand lakes." Its "Qingjiang fish" trademark has been submitted to the State Administration for Industry and Commerce for registration. For a long time, Qingjiang fish series products have not only sold well in the mid-to-high-end aquatic product markets of major and medium-sized cities in China, but have also been exported to more than ten countries and regions including Europe, the United States, Japan and South Korea.
The Qingjiang is a first-level tributary of the Yangtze River, called Yishui in ancient times. Because "the water is clear for ten zhang, and people see its clarity," it was named Qingjiang. The Qingjiang originates from Qiyue Mountain in Lichuan City, Enshi Prefecture, Hubei Province, flows through seven counties and cities including Lichuan, Enshi, Xuan'en, Jianshi, Badong, Changyang and Yidu, and joins the Yangtze River at Lucheng in Yidu, with a total length of 423 km. The basin has clear mountains and beautiful waters, known as the 800-li Qingjiang Gallery.
Experts have determined that the water of the Qingjiang is natural mineral water, rich in various minerals and trace elements essential to the human body. The specific environment, excellent water quality and suitable climate produce the widely renowned Qingjiang fish. After the Geheyan reservoir area was formed, the quiet and elegant Qingjiang water provided especially favorable growing conditions for Qingjiang fish. Good mountains produce good water, good water raises good fish, and good fish taste wonderfully delicious. Being pollution-free, contaminant-free and hormone-free is the greatest feature of Qingjiang fish.
The annual fish output of the Qingjiang reservoir area reaches 5,000 tons. The main varieties include Qingjiang black catfish, red catfish, paddlefish (duck-bill sturgeon), dinggui, yellow catfish (yellow bone fish), jiangtuan (fat tuo), spinibarbus denticulatus, hybrid sturgeon, black carp, red carp, mandarin fish, white carp, silver fish, large-mouth catfish, crucian carp, bighead carp and silver carp, and freshwater shrimp.
