Problems solved by technology

Although its artificial reproduction and nursery have achieved initial success, it is not yet possible to supply fry on a large scale. Farmers mostly rely on natural seedlings. The annual output of this fish is low, and the supply in the market has been in short supply.
At present, the artificial cultured carp has weak constitution and low survival rate in the juvenile stage, and it is easy to die on a large scale. At the juvenile stage, the carp has higher requirements on water quality and other environmental conditions. If the water quality and other environmental conditions are not suitable, it will die. Affect the survival rate of juveniles

Abstract

The invention relates to a technical field of aquaculture, and especially relates to a mystus guttatus young fish breeding method. According to the method, disinfected water is used to culture mystusguttatus young fishes; during the breeding process, parameters of water are strictly controlled; a traditional Chinese medicine composition, which is prepared from honeysuckle flower, fructus forsythiae, thyme, tea, Chinese prickly ash leaf, parsley, and lithospermum, is used to prevent diseases; the survival rate is increased, and the incidence rate is reduced. Compared with the prior art, the incidence rate of young fishes raised by the provided method is lower, moreover, the survival rate is high, and young fishes can safely grow up.

Description

technical field [0001] The invention relates to the technical field of aquatic product cultivation, in particular to a method for cultivating juvenile spotted carp. Background technique [0002] Spotted fish (Mystus guttatus), belonging to the order Siluriformes, the family Scorpionidae, and the genus Mystus guttatus, is commonly known as Mystus guttatus, Sesame fish, White-bearded fish, Xijiang fish, and flower fish. It has a yellowish-brown body with a few thorns. There are black spots the size of sesame seeds, hence the name; this fish is distributed in the Pearl River, Yuanjiang, Jiulongjiang, Hanjiang, Qiantangjiang and other water systems. It has high nutritional value and is known as the crown of the four famous fishes in the Pearl River (spotted perch, perch, rollmouth and mandarin fish), and enjoys the reputation of "king of freshwater fish". The market price is more than 80 yuan / catties. In the south, the rivers in Luodian County, Yunnan, the Leye in the Pearl River...
