Why do seafood fish ponds dig?

The reason for digging in seafood fish ponds is to create a suitable water environment, improve the natural filtering ability of fish ponds, keep warm and freeze-proof, and be beautiful.

1. Create a suitable water environment: Digging can integrate the fish pond with the natural terrain, form a suitable water flow environment, and ensure a more stable growth environment for fish.

2. Improve the natural filtering capacity of fish ponds: digging the ground can connect fish ponds with groundwater resources, and use the natural filtering capacity of groundwater to improve the water quality of fish ponds.

3. Thermal insulation and anti-freezing: Digging can make the fish pond contact with the underground soil, maintain a stable water temperature, avoid the influence of excessive water temperature change on the fish, and also prevent the fish pond from freezing in winter.

4. Beauty: Fish ponds built by digging can be better integrated into the natural environment, with higher aesthetics and easier to attract tourists.
