1 Duck ponds can increase oxygen for fish. The ducks are active, floating on the water, washing and playing. On the one hand, the air can be directly pressed into the water, and on the other hand, the upper saturated oxygen dissolved water can be stirred into the middle and lower layers, which will help to improve the dissolved oxygen in the middle and lower layers of fish ponds. situation. 2 It is beneficial to improve the nutritional environment of the ecosystem in fish ponds. Due to the long-term fertilization, feeding, and pool fish's constant excretion, fish ponds tend to form bottom sediments. Most of these sediments are organic matter. Ducks constantly stir the pond water, which can promote the decomposition of these organic materials. 3 Ducks provide superior bait for fish. Duck dung not only contains a large amount of unabsorbed organic matter, but also contains more than 30% of crude protein, which is the top bait of fish.
