How to prevent this from happening.
First, the pond should be desilted and disinfected immediately during the winter rest period to remove toxic and harmful substances such as ammonia nitrogen and salt;
The second is to change the water frequently during the high temperature and high feeding period to eliminate the old water immediately;
