The invention discloses an intensified artificial breeding method for Australian crayfishes. The method comprises the following steps of: putting pubescent parent crayfishes which pull through a wintering period into a spawning pond according to a proportion of 1-3: 1 of female and male, wherein circulating water is adopted in the spawning pond to automatically control and increase oxygen; sterilizing fertilized ovigerous female crayfishes, putting into small hatching lattices in a hatching pond, wherein one crayfish is hatched in each small hatching lattice, and carrying out water-flow hatching; and enabling hatched young crayfish seeds to leave away from mother bodies after 30-50 days of incubation period, enabling the young crayfish seeds to escape into water through a filter screen of the hatching pond, after all the crayfish seeds at the abdomen of the ovigerous female crayfishes leave away from the mother bodies, immediately separating the parent crayfishes, and remaining the young crayfish seeds to be continuously cultivated for 5-10 days, so that the cultivation can be carried out. According to the method, the artificial intensified breeding incubation can be carried out according to the required offspring seed quantity and the required offspring seed time at any time, the water temperature, the dissolved oxygen, the water quality and the like can be controlled, the method can not be influenced by environment, and the method is high in fertilizing rate, spawning rate and hatching rate.
