Artificial breeding method of eleutheronema tetradactylum

The invention belongs to the field of fish breeding, and discloses an artificial breeding method of eleutheronema tetradactylum. The method comprises the following steps: (1) feeding eleutheronema tetradactylum mackerel fries in seawater to obtain juvenile fish; (2) feeding the juvenile fish obtained in the step (1) with a first-stage feed, performing seawater desalination for the first time, thenfeeding the juvenile fish with a second-stage feed, performing seawater desalination for the second time, and feeding the juvenile fish with a third-stage feed, and performing seawater desalination for the third time until the salinity is 1-0.5%, so as to obtain domesticated fish; and (3) feeding the domesticated fish obtained in the step (2) in different ponds until the fish is caught, wherein the first-stage feed, the second-stage feed and the third-stage feed all comprise kombucha, chitosan oligosaccharide and sodium chloride. According to the method, the immunity of the juvenile fish of the eleutheronema tetradac
