The rearing method of Macrobrachium krylovii in lotus root field is similar to that in rice field, but the stocking amount is larger than that in rice field because there is water all the year round.

The parent of the original Macrobrachium krylovii is directly stocked in the lotus root field for self-reproduction, and the stocking specification is 30-75 kg for every kg2030 Macrobrachium krylovii per mu; The stocking specification is 250-600 young Macrobrachium krimsonii per kg, and 25-45,000 young Macrobrachium krimsonii per mu.

Before stocking, the shrimps should be disinfected. The shrimps can be soaked and disinfected for 3~5 minutes with salt solution with a concentration of about 3%. The soaking time should be flexibly determined according to the weather, temperature and the tolerance of the shrimps themselves. Shrimp species purchased from other places should be soaked in field water for 1 min, lifted and put on hold for 2~3 minutes, then soaked for 1 min, and repeated several times, so that the surface and gill cavity of shrimp species can absorb enough water before stocking, so as to improve the survival rate. After being disinfected and treated by the above method, the original crayfish recovered quickly and the survival rate was high after being put into the lotus root field.
