Dissolved oxygen in fish ponds is maintained at a normal level in order to keep fish activities normal. Fish need oxygen to survive, and they obtain it from the water through their gills. The amount of dissolved oxygen in the water can vary depending on factors such as temperature, water movement, and the presence of aquatic plants and algae. If the dissolved oxygen level in a fish pond drops too low, the fish may become stressed and their growth and health may be affected. In extreme cases, low dissolved oxygen levels can lead to fish kills. Therefore, it is important to maintain a normal level of dissolved oxygen in the fish pond to keep the fish healthy and active. There are several ways to maintain dissolved oxygen levels in a fish pond, such as aerating the water with a pump or fountain, adding oxygen-producing plants, or reducing the amount of organic matter in the water. By maintaining the proper level of dissolved oxygen, fish farmers can improve the quality of their fish and ensure a healthy and productive fish farming operation.
