(1) The shape and depth of shrimp ponds are basically similar to those of freshwater fish ponds. Generally speaking, rectangular shrimp ponds are more common. Rectangular shrimp ponds should be long from east to west and wide from north to south. This shrimp pond has a long light time, which is beneficial to feeding management and netting operation. Shrimp ponds should not be too wide, the width is generally 40 ~ 60 meters, and the length of shrimp ponds generally depends on the local topography, specifications and the overall layout of shrimp ponds. Generally, 4 ~ 6:1is appropriate. Generally, the shrimp pond should be 5 ~ 15 mu. The entrance and exit channels, roads and electricity of the shrimp pond should be oriented, the shrimp pond should be sliced neatly, the pond culture and ridge planting should be combined with each other, the fishery machinery should be integrated into a system, and the cultivation and processing should be integrated. Generally, the average water depth of shrimp ponds is 1.2 ~ 1.5 m, and the ditch depth is more than 2 m, so as to drain water first when harvesting, and draw nets in the deep ditch occupying 1/3 of the pond to improve the fishing rate. The bottom of the pond should be flat, with a slight slope, and gradually inclined from the water inlet to the water outlet of the pond, with an inclination of 1: 200 ~ 500, so that shrimp and water can be concentrated in a small area when fishing or draining the pond for drying, which is convenient for fishing or drying the pond.

(2) Feeding platform in shrimp ponds Intensive culture in shrimp ponds mainly relies on artificial feeding. Generally speaking, the feed should be placed in a shallow place around the shrimp pond, and sometimes it should be placed a few meters away from the edge of the pond, which can also be regarded as a "feed table". The feed platform requires the pond to have a hard beach foot with a width of not less than 2 meters, which surrounds the pond and is built 40 ~ 80 cm below the water surface.

(3) Water inlet and drainage of shrimp ponds Each shrimp pond must have a water inlet and a water outlet. Water inlet and outlet systems should not be shared, but should be strictly separated. The water inlet of each shrimp pond is directly connected with the water inlet channel, and the wastewater discharged from other shrimp ponds shall not be mixed. The water in each shrimp pond should not be used with each other, otherwise it will easily cause water pollution and spread germs.
