The invention belongs to the technical field of aquaculture, and discloses a cherax quadricarinatus rice self-breeding method. The method comprises the steps of selecting a rice field suitable for rice and shrimp comprehensive breeding, wherein the rice field is provided with a 2-4 m wide and 0.8-1.2 m deep shrimp ditch; arranging an enclosure culture ditch, adopting an anti-escape net at the periphery, building an anti-escape facility, and isolating the enclosure culture ditch by means of the anti-escape net on the basis that the area ratio is 2:1-3:1; performing parent shrimp stocking, wherein female shrimp and male shrimp are stocked at the isolation region; performing offspring seed self-breeding, removing a sandbag and isolating the anti-escape net during the parent fish self-breedingperiod, and performing mating self-breeding on parent fish, wherein produced shrimp seeds penetrate through the anti-escape net and enter the rice field for natural growth. The culture parent shrimpis used for performing self-breeding, no shrimp seed needs to be purchased, the production cost is effectively lowered, and the rice field comprehensive breeding benefits are improved; the shrimp seedobtained after self-breeding penetrates through the anti-escape net for natural growth, damage to the shrimp seed during transportation and moving is avoided, and the shrimp seed survival rate is effectively increased.
