The dissolved oxygen content in water has a crucial impact on the survival and growth of organisms. When the water contains sufficient dissolved oxygen, the water quality will become pure and conducive to biological growth. Conversely, anaerobic bacteria in the water will accelerate their reproduction and cause water quality deterioration. If the dissolved oxygen is below 4mg/L, it may even lead to suffocation and death of fish. Therefore, monitoring dissolved oxygen in water quality is of great significance for ensuring aquaculture.
In daily aquaculture, factors such as temperature, air pressure, light, and water quality can all affect the dissolved oxygen in water. As the temperature of water increases, the activity of bacteria, algae, fish, and other aquatic animals in the water increases, and the dissolved oxygen content in the water decreases accordingly. Similarly, if the air pressure in the water is lower, oxygen is more likely to overflow from the water, leading to oxygen deficiency in the water. In addition, the content of ammonia nitrogen, nitrite, nutrients, and pH value in water will cause aerobic activity of microorganisms in the water, leading to a decrease in dissolved oxygen in the water. In summary, using an instrument with dissolved oxygen and pH measurement functions is very helpful for reasonable oxygenation, optimizing feed feeding amount and feeding time, and regulating the aquaculture water environment.
