Method of freshwater aquaculture of Litopenaeus vannamei in net cage

A method of freshwater aquaculture of Litopenaeus vannamei in a net cage includes an early-stage preparation step of net-cage aquaculture, a water quality and salinity detection and preparation step before shrimp seeds are placed into the net cage, a shrimp seed feeding step for the net cage, a separative aquaculture step, a culture period management step and a harvesting step. The early-stage preparation step includes A, selecting a proper aquaculture water area; B, setting the net cage; C, placing the net cage into the water one month before the shrimp seeds are fed. The separative aquaculture step includes separating and transferring the shrimp seeds three times in the 20th day, the 40th day and the 60th day, reducing the density and prompting growth of the shrimp seeds. The culture period management step includes daily management and prevention and control of shrimp diseases. The method of freshwater aquaculture of the Litopenaeus vannamei has the advantages that a good well-off way is provided for efficient special aquaculture of various inland lakes and reservoir areas; temporary-rearing desalination formula of ultralow salinity smaller than or equal to 0.5%o; the net cage applicable to freshwater aquaculture of the Litopenaeus vannamei is modified; aquaculture quality of the Litopenaeus vannamei by the net cage is better; benefits of the Litopenaeus vannamei cultured in the net cage are considerable.
