When hypoxia is not serious, shrimp can recover slowly by supplementing oxygen in time. If it has been hypoxic for a long time, the shrimp itself is dying, and the oxygenation can hardly be saved. To judge whether hypoxia is serious, mainly depends on the performance of shrimp, if only not very active, that there is still a rescue, if there is the performance of lying on the side, it can give up.
1, timely oxygenation: shrimp in hypoxia, the first thing to do is to give it oxygen in time. There are many ways of oxygenation, the most commonly used is the oxygen pump, which can be opened regularly for a period of time, so that oxygenation every day can eliminate the occurrence of hypoxia, which is of great help to the health of prawns.
2. Pay attention to temperature control: The reason why shrimp lack oxygen is not only due to the lack of oxygen in the water body itself, but also due to the temperature. Because the dissolved oxygen in the water will decrease when the temperature rises, it is easy to lack oxygen in summer. At ordinary times, we must pay attention to temperature control, keep the water temperature below 24 C, but not too low, low temperature shrimp also has certain harm.
3. Reduce the density: The reason for the lack of oxygen is that the oxygen consumption is too large. If there are too many shrimps in the culture, the culture density is too large, and the lack of oxygen is unavoidable. In view of this situation, if you do not want to oxygenate in time, the best way is to reduce the density of feeding and reduce the number of feeding.
