As the temperature continues to rise, the temperature is obviously higher than some time ago, the hot weather will be more and more, therefore, the occurrence of aquaculture diseases will also increase, are the points to note, aquaculture farmers reference. Increase dissolved oxygen in water. Aerobic equipment can be maintained in the sunny noon to open the aerator more than 2 hours, encountered rainy days or sudden weather changes to promptly open the aerator. If there is no aerator can be submersible pump playing in the pool circulating water (time before 3 o’clock in the afternoon, should not be carried out in the evening), enhance the convection and exchange of water, or prepare aerosols, depending on weather conditions in advance to Anti-hypoxia caused by water quality mutations and pan-pool.
