Artificial breeding method of unio douglasiae

The invention relates to an artificial breeding method of unio douglasiae. The method specifically comprises six steps of parent mussel breeding, host fish breeding, glochidium collection, parasitic infection, host fish breeding after infection and infant mussel breeding after fry falling off. Host fish is infected with glochidium according to the proportion of 1000 to 1500 per fish; the infected host fish is put into a running water nursery pond to be fed; feed is throw for breeding until glochidium completely falls off to obtain infant mussels; and the infant mussels are further placed in an environment with sufficient dissolved oxygen, and running water cultivation is carried out to obtain young mussels. The method provided by the invention is helpful to solve the problems of short supply of the unio douglasiae in the market and low reproductive rate of the unio douglasiae in the nature, and meanwhile fills the blank of research on an artificial breeding method of the unio douglasiae. The artificial breedi
