Can a of lack of oxygen in one night? A fish will die of lack of oxygen in one night. Although fish live in water, they still need to breathe, but instead of taking oxygen from the air, they take it from the water. If the oxygen content in the water body is relatively low, the fish will continue to be in a state of hypoxia, there will be floating head, turning over and other phenomena, and finally the fish will die. Therefore, attention must be paid to oxygenation to ensure that dissolved oxygen is sufficient.
1. Daily oxygenation: Fish farming must be oxygenated every day, because once the phenomenon of hypoxia occurs, it is difficult to judge when the subsequent hypoxia will occur again, because it can not be prevented, so it is necessary to keep the dissolved oxygen in the water body adequate at all times. Of course, if the breeding density is not large, and they are all small fish, they can do without oxygen pumps.
2. Open the tank for oxygenation: It is necessary to open the tank for fish farming for the first time. When opening the tank, it is necessary to culture nitrifying bacteria, so it must be properly oxygenated. Nitrifying bacteria belong to aerobic bacteria, and it is easier for them to grow and reproduce in an environment with sufficient oxygen. When they reach a certain scale, the nitrification system of the water body is established, so as to better complete the ecological cycle.
3. Sick oxygenation: If the fish is sick, it also needs oxygenation, which can promote metabolism, help its disease recovery, and supplement the oxygen consumed by drugs.
