In the winter, the temperature is low, the activity of fish, feeding will be relatively small, some farmers will neglect the management of winter fish farming, resulting in an increase in the mortality of overwintering fish. In fact, this can be avoided, and the survival rate of fish can be improved by monitoring the water quality. This chapter water quality online monitoring instrument manufacturers to understand aquaculture water quality testing precautions together!
Whether the fish can safely overwinter has a great relationship with the pond conditions, the health of the fish themselves and the pond management in winter. The water quality online monitoring instrument is used to detect the water quality of the pond, and corresponding measures are made through the relevant data to improve the survival rate of fish. The problems to pay attention to are: 1. Pay attention to adding water. 2. Strengthen management.
1.The winter rainfall is reduced, the water level is relatively low, the pond water depth should be maintained at a minimum of more than 1.5m, and the water should be added when the water level is too low. When adding water, water should be injected early and frequently, and the amount of water injected at one time should not be too much to avoid excessive changes in the water temperature of the pond, and the activity of the fish is not conducive to overwintering.
2.Can not ignore the management work, the use of water quality online monitoring instrument for real-time monitoring of water quality, timely check the status of fish activities. In winter, the solar light is less, the photosynthesis of phytoplankton is weakened, often resulting in insufficient dissolved oxygen in the culture environment. At the same time, it is necessary to pay attention not to apply organic fertilizer, reduce the consumption of dissolved oxygen, and prevent the oxygen deficiency of fish in winter. The fish did not stop feeding completely during the overwintering period. When the temperature was high and the weather was warm and windless, they fed a small amount of bait according to the actual situation. Regularly patrol the pond, find problems in time to solve.
