The invention discloses a complete artificial propagation method for aspiorhynchus laticeps. The method is operated according to the following steps that reserve parent fishes are selected and cultivated from the first filial generation, obtained through artificial breeding, of the aspiorhynchus laticeps cultivated in an indoor intensive cultivation workshop; the first filial generation parent fishes of the aspiorhynchus laticeps are spawned artificially; second filial generation roe is hatched artificially; second filial generation newly-hatched fish fries are cultivated artificially. The complete artificial propagation method for the aspiorhynchus laticeps has the advantages that the fertilization rate, the hatchability and the survival rate are high, the fertilization rate canvbe more than 76 percent, the hatchability and the survival rate can be more than 81 percent, aspiorhynchus laticeps resources can be gradually recovered, and the method is an effective and feasible endangered aquatic animal conservation method.
