The number of aerators (bursting discs) placed in aquaculture depends on various factors, including breeding density, breeding species, water quality conditions, and the type of aerator equipment used. Here are some common guiding principles:
1、 Determine based on breeding density and variety
1. High density aquaculture: For high-density species such as shrimp, 5-8 aerators may need to be installed per acre to ensure sufficient oxygen supply.
2. Ordinary farming: If ordinary varieties such as the four famous domestic fishes are farmed, 3-5 oxygen increasing plates may be installed per mu.
2、 Determine based on the type of oxygenation equipment
1. Disc installation method: In this method, steel bars with a diameter of 4-6 millimeters are bent into a disc frame, and the aeration tube is fixed on the disc frame. For a one acre fish pond, usually 3-4 aeration plates need to be installed according to the shape and size of the pond. These aeration plates are fixed at the bottom of the tank by a plate frame, with a height of 10-15 centimeters from the bottom to ensure uniform release of oxygen.
2. Nano oxygen discs: The number of nano oxygen discs required per acre of land also depends on the breeding density and variety. Under high-density farming, it may be necessary to install 58 nano oxygen discs per acre; Under regular farming, it may be necessary to install 35 nano oxygen discs per acre.
3、 Precautions
1. When determining the number of aerators, factors such as the fish pond, water quality conditions, and the power and efficiency of the aerator equipment also need to be considered.
2. The oxygenation tray should be evenly distributed in the fish pond to ensure that oxygen can be evenly distributed throughout the entire aquaculture area.
3. Regularly inspect and maintain oxygenation equipment to ensure its normal operation and functioning.
In summary, the number of aerators placed in aquaculture is not fixed, but needs to be flexibly adjusted according to the actual situation. It is recommended to consult with professionals or determine based on farming experience in actual operation.
