The invention relates to an artificial propagation method for F1 generation of snow arowana. The artificial propagation method comprises selection of parent fishes, cultivation of the parent fishes, preparation of artificial insemination, artificial spawning induction and artificial insemination. The method comprises uniformly dispersing and adhering oosperms on a net without knots, standing for 10 to 15 min to make the oosperms adhere to the net, setting out the net with adhered oosperms in a hatching pond for 30 to 48 hours, wherein the temperature and dissolved oxygen of water for hatching in the pond are respectively 28 DEG C to 30 DEG C, and 5 mg/L to 12.5 mg/L. The artificial propagation method can artificially hatch the F1 generation of snow arowana, the problem that parent fishes may eat fries can be completely eradicated, the family of the F1 generation of snow arowana can be established by using the method, seed selection of families can be convenient, the ties of consanguinity between later generations and the parents can be clear, inbreeding can be prevented, degeneration of germplasm of the later generations caused by inbreeding can be avoided.
