According to feeding and habitat ecology the technical process of Macrobrachium nipponense culture was designed. By the cultivating practice the following resultswere recorded: (1) The production of M. nipponense was 90 - 105kg/1000m2, the prawns(2.0- 2. 5g/ind) had 60-70%, when one time breeding prawn fry, much times catchingprawns per year. (2) The yield of M. nipponense was 204kg/1000m2, when two tirnes breeding fry, two times catching prawns, but it was too miscellaneous. (3) It is nice that the fishpond was rectangle, 667- 2000m2 culture area, 1.0m depth of water per pond. (4) It is goodthat the protein in diets of M. nipponense was 35-40%, two times exchange water per day,the ratio of feeding was 2. 8-8.0%.
