The amount of foodstuffs fed for the duration of feeding is normal within 3 hours. After 2 hours, it indicates that the amount of feed is insufficient. There is still a portion of the fish that are not fed. The amount of feed should be increased when feeding the next time. No fish was eaten in 4 hours, but the fish school had left the food court, indicating that the amount of feed was large, and the amount of feed was appropriately reduced for the next feeding.
Look at the growth of fish. The food intake is gradually increased after the start of eating. During the feeding plan for the week or the tenth, the changes at the beginning of the week and the weekend or the beginning and end of the ten days are to be observed. If the number of shots is the same every day, it will be eaten within 2 hours at the end of the weekend or at the end of the ten days, indicating that the weight of the fish has increased. It is necessary to increase the amount of feed, and by the beginning of fishing in December, this method can be used to identify and control.
After watching the water surface, the fish will drill to the bottom. In particular, fry or species of fish swimming in groups on the water, this is a manifestation of severe hunger, commonly known as "race horse disease", to immediately feed, blocking mad tour, otherwise they will die in large numbers.
As for fish and fish that are mainly eaten by plankton, they can observe the thinness of water quality. When the water quality is thin, they should be used to cultivate plankton. If the water quality is too fat, when the water quality is deteriorated, it is necessary to change the water immediately. Increase oxygen.
