The placement distance of microporous aerators in fish and shrimp ponds mainly depends on the aquaculture area, aquaculture density, water depth, and the required oxygenation effect. Here are some specific suggestions:
1、 Disc installation method
1. Oxygenation disk configuration: Use 46mm diameter steel bars bent into a disk frame, and fix the aeration tube on the disk frame. The recommended total length of the tray frame is 1520 meters.
2. Placement distance and quantity: 34 aeration plates per acre. This means that if the pond area is 1 acre (approximately 667 square meters), approximately 34 aerators are needed, evenly distributed throughout the pond.
3. Fixed position: The tray frame should be fixed at the bottom of the pool, 10-15 centimeters away from the bottom, to avoid stirring the sediment at the bottom of the pool during oxygenation.
2、 Strip installation method
1. Aeration tube configuration: The total length of the aeration tube is about 60 meters, with a tube spacing of about 10 meters.
2. Placement distance and quantity: The height difference should not exceed 10 centimeters, and it should be fixed at the bottom of the pool, 10-15 centimeters away from the bottom. The number of aeration tubes per acre depends on the specific layout and aquaculture density of the pond, but sufficient aeration area and effectiveness should be ensured.
3、 Other precautions
1. Power of aerator: The power of the blower equipped per acre is usually between 0.1 and 0.15 kilowatts, depending on the breeding density and oxygen demand.
2. Usage time: Determine the time and period for starting up and increasing oxygen based on the pattern of dissolved oxygen changes in the water body. For example, during peak farming periods or weather changes, it may be necessary to increase the start-up time and frequency.
3. Maintenance: Regularly clean the oxygenation disc and aeration tube to prevent micropore blockage. At the same time, check if the fixing device is secure to ensure that the oxygenation disc will not shift or fall off.
4. Monitoring and Control: It is recommended to equip dissolved oxygen monitoring equipment to monitor the dissolved oxygen content in the water in real time and make adjustments as needed.
In summary, the placement distance of microporous aerators in fish and shrimp ponds is not fixed, but needs to be flexibly adjusted according to the actual situation. By reasonable configuration and use, the dissolved oxygen content of water can be increased, promoting the growth and health of fish and shrimp.
