Bioaerobic phytoplankton releases oxygen from photosynthetic organisms and is the major source of nutrients in water bodies in overwintering fish ponds. Therefore, the fish pond water with more water quality is injected into overwintering fish ponds, and there are more fertilizer and water phytoplankton. Through photosynthesis, the amount of dissolved oxygen in the pool water can be significantly increased. However, the amount of water injected should not exceed 1/5 of the pool water. If the pool is thin, apply 0.5 to 1 kg of urea and superphosphate per acre of water. However, care should be taken not to use organic fertilizers to prevent pollution of water quality. Splash lime every 20 days or so to clarify the water quality and increase the transparency of the water body, thereby increasing the amount of sunlight injected into the water body and enhancing photosynthesis.
Chemical Oxygenation For small reservoirs such as wintering in greenhouses and wintering in water tanks, oxygen deficiency emergency aids such as calcium peroxide or hydrogen peroxide may be added. Calcium peroxide and hydrogen peroxide add 10 to 20 milligrams per cubic meter of water, which can act as oxygenation 1 to 2 ml/liter. However, attention must be paid to the appropriate amount, not too much, to prevent damage to the fish.
Mechanical aeration is the use of power to drive the air pump and press the air into the inflatable tube laid under water. There are many dense holes on the inflatable tube, so that the air can diffuse into the water and increase the dissolved oxygen in the water. The second is the circular injection of water. In other words, the two nearby fish ponds are connected by a concrete pipe at the corner of the pool, and a pool of water is pumped to another pool of water at another corner. The water in the two fish ponds is circulated to increase the contact surface between the water and the air and to increase the dissolved oxygen in the water. . The third is to stir the pond water. In the severe winter season, the ice on the surface of fish ponds is broken, and the bottom water of fish ponds is stirred. After the lower layer of water is mixed with the upper layer of water, the upper layer of dissolved oxygen is transported to the lower layer to supplement the deficiency of dissolved oxygen in the lower layer of water. Conditional available air compressors are artificially used. Air is fed into the body of water, or high-oxygen water is fed into the body of water using an ejector.
