Look at the length of time you eat. Feeding is normal within 3 hours after feeding, 2 hours or so after eating indicates that the amount of feed is insufficient, and some of the fish are not full, should increase the amount of feeding; if extended to 4 hours has not finished, and fish The group had left the food court and showed that it was more than enough to eat. The next feeding could be reduced in moderation. Second, look at the size of fish growth. After the fish eats, the food intake gradually increases. In the feeding plan for the week or the ten-day period, the changes at the beginning of the week and the weekend or the beginning and end of the ten days should be observed. If the amount of feed is not changed, and it is finished at the end of the weekend or the end of the second day, it means that the weight of the fish has increased, the amount of food is large, and there is no enough food. Three to watch the water movement. After eating, the fish generally sink to the bottom. After feeding, if the fish is not sick and frequently moves on the water surface, it is a manifestation of hunger; in particular, fry or fingerlings swim in groups on the water. This is a manifestation of severe hunger, commonly known as “race horse disease,†and should be eaten immediately. Block mad tours, otherwise it will kill in large numbers. Four to see the water quality. For mandarin fish and clams, which use plankton-based fish, the water quality can be observed to determine whether they meet their growth requirements. When the water quality is thin, use fertilization methods to cultivate plankton. If the water quality is too fat and the signs of deterioration appear, the water should be turned on immediately to increase oxygen. If necessary, trichlorfon drugs can be used to kill zooplankton and promote the growth of fish. Winter
