Abstract

An artificial breeding method of coreius guichenoti comprises establishment of key ecological factors of an ecological pond, wherein the key ecological factors of the ecological pond include cultivated phytoplankton control range of 10-100 mg / L, bred zooplankton control range of 3-10 mg / L, water temperature control range smaller than or equal to 32 DEG C, dissolved oxygen control range of 3-20 mg / L, ammonia nitrogen control range smaller than or equal to 0.6 mg / L, transparence control range of 50-100 cm, and released density control range of 50-300 kg / mu. The artificial breeding method has theadvantages that by regulating and controlling the key ecological factors of the ecological pond, the occurrence probability of fatal infectious diseases in the artificial coreius guichenoti breedingprocess is reduced, artificial coreius guichenoti breeding is achieved, the survival rate of breeding reaches 80% or above, accordingly an existing method for treating fatal infectious diseases mainlyby relying on drugs in the coreius guichenoti breeding process is changed, and the existing method oriented to treatment is changed into the method oriented to prevention.

Description

technical field [0001] The patent of the present invention belongs to artificial breeding technology, specifically a new artificial breeding method of round mouth copper fish. technical background [0002] The round mouth copper fish (Coreius guichenoti), belonging to the class Osteichthyes, Cypriniformes, Cyprinidae, Gobioninae, Coreius, also known as water secret, square Tou, Feituo and Twisted Fish are mainly distributed in the main tributaries of the upper and middle reaches of the Yangtze River, the lower reaches of the Jinsha River and the tributaries of the Minjiang, Jialing and Wujiang. The round mouth copper fish is a lower-level fish, omnivorous, and feeds on aquatic insects, mollusks, plant fragments, fish eggs, and fry. The largest individual can reach 4 kg. It is a rare and unique fish in the Yangtze River with high nutritional value, and it is also the main economic fish in the upper and middle reaches of the Yangtze River. [0003] In recent years, due to va...
