Low-salt pond engineering culture method for mandarin shrimps

The invention relates to a low-salt pond engineering culture method for mandarin shrimps. According to the method, high-density intensive culture is conducted in the hard-bottom soil pond in the early stage, the disease stage of early growth of the mandarin shrimps is avoided, and the growth stress resistance of the mandarin shrimps is improved. Along with the growth of the mandarin shrimps, the living space of the mandarin shrimps is gradually compressed, and the mandarin shrimps kill each other seriously. Therefore, in the middle and later periods of cultivation, the fish is transferred into a net-laying soft-bottom soil pond which is larger in space, rich in biological bait and high in water quality self-adjusting capacity for cultivation. According to the method, through engineering transformation of the low-salt shrimp pond, the advantages of the hard-bottom soil pond and the laid soft-bottom soil pond are fully utilized, the morbidity rate of the mandarin shrimps is reduced, it is ensured that the manda
