The layout of fish pond aerators mainly depends on factors such as water source conditions, breeding species, breeding density, total inflow and drainage energy consumption and other factors.
1. Water source status: Whether the water source is abundant and whether the water quality is consistently good. If the water quality is good, you can consider less allocation. On the contrary, use more allocation and change the water more when the water quality is good.
2. Breeding species: Vannamei shrimp is an oxygen-consuming species and requires less oxygen at the bottom of the fish.
3. Breeding density (yield per mu): high proportions are more, low proportions are less.
4. Total inflow and drainage energy consumption: If the inflow and drainage energy consumption is low, the aerator can be considered less equipped. The energy consumption is large, and the composition has to be large.
5. Economic analysis: Consider the electricity bill and the price ratio of fish, meat and shrimp. If the local electricity bill is relatively high and the price of fish, meat and shrimp is relatively low, consider less matching. Instead, match up more. In waters with sufficient dissolved oxygen, the oxidation of organic matter is relatively complete, and the products are non-toxic and low-toxic substances such as CO2 and H2O. However, if the water lacks dissolved oxygen and the oxidation of organic matter is not complete, organic acids and amine harmful substances, nitrites, and hydrogen sulfide will occur in a state of insufficient dissolved oxygen. Therefore, when the nitrous acid and hydrogen sulfide are high in the aquaculture water environment, the only thing to do is to increase the oxygen.
