The invention relates to the technical field of lobster breeding, and discloses a lobster breeding based on a rice field. The lobster breeding based on the rice field comprises the following steps: selecting and transforming of a rice field, namely selecting a rice field which has sufficient water sources, has no
water pollution, is not easy to dry during a
dry season and to drown in winter, and has fertile soils; and after rice is harvested, digging the rice field into a concentric-square-shaped
pool with a width of 100-120 cm and a depth of 50-70 cm, and digging a cross-shaped
ditch with a width of 150-180 cm in the middle of the
pool, wherein the four ends of the cross-shaped
ditch respectively communicate with the
pool. According to the lobster breeding method based on the rice field,through the transformation of the rice field, and the using of the concentric-square-shaped pool and the cross-shaped
ditch, activity area of lobster seedlings is increased, thereby increasing the activity amount of the lobster seedlings, and improving the meat quality of the lobster seedlings; at the same time, blocking on the lobster seedlings can be performed, and crashing between the lobster seedlings and rice seedlings is reduced, thereby increasing the yield of the rice field; and
oxygen-increasing equipment is used to improve an
oxygen content in water, and improve the
survival rate ofthe lobster seedlings, thereby improving yields and improving incomes.
