Ecological breeding method for intercropping of macrobrachium rosenbergii and parents of scatophagus argus linnaeus

The invention discloses an ecological breeding method for intercropping of macrobrachium rosenbergii and parents of scatophagus argus linnaeus. The method is characterized by comprising the steps of cleaning and sterilizing a pond before stocking when the water temperature of the outer pond is above 20-22 DEG C; feeding water after a week, feeding 70-80cm of water for the first time and putting desalinated fishes of macrobrachium rosenbergii after 7-10d, wherein the stocking density is 30,000-40,000 per mu; feeding prawn slices and an open shrimp feed in the initial period of stocking, and then feeding a No.0 material, a No.1 material or a No.2 material; feeding 10-20cm of water every two weeks after first feeding until the pond is full, changing the water once every two weeks, changing the water once every week during cultivation and in the later period and keeping the transparency of the water in the pond at 30-40cm; putting backup parents of desalinated scatophagus argus linnaeus after stocking the macrobr
