1, daily management. Observe the fish's activities and eating every day, and check whether the water in and out is abnormal. During indoor domestication, siphon the impurities in the domestication pool in time, keep the pool water clean and the environment quiet, and spray 3 ~ 5ml/m 3 iodine preparation solution once a week. Fresh water is often added and disinfected regularly in outdoor large ponds. We should master the feeding principle of 7 ~ 80% full, and stop feeding every half month 1 day. Record the changes of water temperature, dead fish and bait weight in the domestication pool every day.

2. Prevention and treatment of fish diseases. Spring fish is different from the natural environment in the process of domestication, which is easily affected by many factors and will cause fish diseases. Therefore, the pond should be disinfected before stocking; And observe the activities and food intake of spring fish during domestication; When fish diseases are found, targeted measures should be taken in time to restore spring fish to life. Insects should be killed every 20 days in the month when the water temperature is relatively low. Pesticides (generally trichlorfon, mirex, abamectin, etc.). ) should be used alternately to prevent parasites from developing drug resistance.
