 The present invention will be described in detail below in conjunction with specific embodiments.
 A method for breeding Macrobrachium rosenbergii shrimp larvae adopts the following steps:
 Broodstock selection: In October of each year, when the water temperature drops to about 20°C, select qualified species of shrimp from the breeding farm for pond breeding of broodstock. Quality requirements: The broodstock must be clean, sturdy, complete appendages, and free of lesions on the whole body. The specifications of the broodstock are: 40-60 tails / kg for females; 30-50 tails / kg for males; the second step is orange; the ratio of female to male for the broodstock is 3-4:1.
 Broodstock overwintering cultivation: before broodstock enters the pond, first disinfect the winter pond, and then stock broodstock, the broodstock stocking density is controlled at 30-50 per meter 2 . Manage water quality and feed during the cultivation process.
