In order to make full use of resources, excavate the potential of water production and raise the breeding efficiency, we did a good experiment on aquaculture using special aquatic products such as freshwater shrimp and bighead carp, without affecting the production of crabs and achieved good results. Water can increase the effectiveness of 200 to 500 yuan, has now formed a more mature nesting mode.
