Abstract

The invention discloses an artificial cultivation and domestication method of salvelinus leucomaenis fries, belonging to a cultivation method of fish fries, in particular to a cultivation method of salvelinus leucomaenis fries, and solving the problems of death, difficult domestication, low domestication rate and difficult artificial feed intake of the salvelinus leucomaenis fries because the salvelinus leucomaenis fries are only fed by the tubificidaes and can not take comprehensive nutrients in the cultivation and domestication process by adopting the traditional fry cultivation method. The artificial cultivation and domestication method of the salvelinus leucomaenis fries is sequentially divided into an incubation management stage, a zooplankton feeding stage, a zooplankton and tubificidae mixed feeding stage, a tubificidae feeding stage, a tubificidae and artificial feed mixed feeding stage and an artificial feed feeding stage. The method has the advantages of simple and convenient operation and low cost and ensures that the quality of the domesticated fries is good and the survival rate of artificially domesticated fries is improved to 79 percent from initial 20 percent, thus the method can be used for cultivating the salvelinus leucomaenis fries.
