Many small fish in our fish pond die every morning, and the weather these days. One day the sun. Rainy day? Why did so many people die? What should I do? every day

Stress can be reduced by the following measures:

1. Start the aerator more: start the aerator to stir and aerate, increase the dissolved oxygen in the pool water, and relieve the stress reaction of fish.

2. Oral vitamin C: dissolve vitamin C in water first, then spray it evenly on the artificial compound feed, and dry it in the shade for about 30 minutes before feeding.

3. Adding zeolite powder: the dosage is per cubic meter of water 10-20g.

4. Spraying glucose and vitamin C: Sprinkle 2 kg of glucose and 200 g of vitamin C at the depth of water per mu 1 m for 2-3 days.

5, using microbial agents; The whole pond is sprayed with biological agents such as photosynthetic bacteria (5-8kg/mu) or EM compound bacteria to eliminate harmful gases such as ammonia nitrogen, nitrite and hydrogen sulfide in water and improve water quality and sediment.

6. Sprinkle quicklime all over the pool: After the rainstorm, the PH value of the pool water will be greatly reduced. Spraying quicklime (5- 10kg/ mu) everywhere in the pool water can make the PH value of the pool water relatively stable.
