The invention discloses a full-artificial breeding method for megalonibea fusca. The method comprises the following steps of: getting parent fish seeds from natural sea areas; carrying out reinforced breeding on parent fish; carrying out artificial spawning on the parent fish; carrying out hatching on fertile eggs; carrying out indoor artificial cultivation on juvenile fish; carrying out indoor nutrition strengthening cultivation on the juvenile fish in an alevin stage; carrying out ecological breeding on the alevin which are moved into an earthen pond after the alevin stage; and breeding thealevin into large-size seedlings, and the like. The full-artificial breeding method provided by the invention is a mode applicable to the large-scale production of megalonibea fusca fries. After carrying out three-year cultivation on first-generation juvenile fish which is successfully artificially bred, sexually-matured first-filial-generation parent fish is cultivated, and then second-generation juvenile fish is bred from the first-filial-generation parent fish, thereby achieving the full-artificial breeding. The full-artificial breeding method breaks through the bottleneck that because themegalonibea fusca belongs to endangered fish species, parent fish sources are extremely difficult, and realizes the large-scale artificial breeding and culturing industrialization of the megalonibea fusca.
