Measures for dissolved oxygen (DO) in silver salmon farming! Stable production with oxygen fighters.
High Concentration Gas Dissolution Device - Oxygen Fighter
During the freshwater rearing period of silver salmon. Increase dissolved oxygen (DO) with oxygen fighters to stabilize production!
During the freshwater rearing period of silver salmon, it is essential to manage water temperature, adjust feeding amounts, and maintain dissolved oxygen (DO) levels and water quality. Among these, ensuring sufficient dissolved oxygen is a crucial point for stabilizing rearing. **Four Benefits of Maintaining High Dissolved Oxygen:** 1. Prevention of Growth Decline: Stops growth halts caused by decreased appetite. 2. Prevention of Water Quality Deterioration: Suppresses the accumulation of ammonia nitrogen from waste and residues. 3. Stabilization of Water Quality: Activates aerobic microbial populations in the water. 4. Reduction of Individual Load: Corresponds to the oxygen consumption requirements of silver salmon. The high-concentration gas dissolution device "Oxygen Fighter" differs from traditional aeration by dissolving oxygen into water with minimal bubble production. Therefore, it can reliably secure high DO levels even in shallow aquaculture ponds. It can be retrofitted to existing equipment, and there are a total of nine freshwater models available (with maximum flow rates ranging from 60L/min to 5000L/min). While there are running costs for pump power (0.4kW to 15kW) and oxygen, it maximizes profits through the prevention of fish mortality, size increase, and reduction of rearing periods.

Company information
At Daiei Manufacturing Co., Ltd., Environmental Division, we propose a high-concentration oxygen dissolution device as an alternative to conventional aeration methods. We aim to contribute to the establishment of a healthy social environment by utilizing this oxygen dissolution technology. In rivers and lakes, we create a saturated dissolved oxygen state near the bottom, promoting the activation of aerobic microbial communities. In industrial wastewater, high concentrations of dissolved oxygen have also made it possible to address high-load, high-density activated sludge (microorganisms). It is also used for the dissolution of gases other than oxygen.
