Make sure that the feed is fresh and not stale when feeding. Feed must be cut into small pieces. If it is frozen, it needs to be thawed first and then fed when the temperature is similar to that of the pool water.
Feed 3%-10% of the total fish stocks every day. In case of insufficient natural bait, artificial bait can be added appropriately. Usually, the food intake of 15-day-old fry will be doubled. At this time, some large crustaceans and chopped earthworms should be fed, and chopped mixed fish can be fed after 20 days, and adjustments can be made according to the specific situation.
In the case of insufficient bait, snakehead often catches the big fish eat small fish. In order to prevent this from happening, it is necessary to separate the young fish with a body length of 3-4cm and a daily age of about 20 days and raise them in groups at the latest of 5-6cm.
