Feeding characteristics of fish ponds in September-November
First, feeding characteristics
The feeding plan was mentioned in order to make the farmers have a clear picture. The feeding amount of pond feed from March to August is a gradual process. It reached the highest point in early September, and then it was a declining process. It ended in November. Late. The climate in September is suitable for the growth of fish, which is also the peak season for feeding. Feed intake accounted for 22% of the annual total, and the share was the highest in a year. October feed intake accounted for 18% of the annual total, slightly lower than August (19%). In November, feed intake accounted for 5% of the annual total, and feeding ended in late November. According to the growth characteristics of fish, the monthly amount of feed is usually divided into three periods: above, middle, and late. One-third of the total plan for the month is the amount in mid-range, and the ten-day amount is evenly distributed to each day. At present, due to the cooling of the weather, the amount of feeds in the upper, middle, and late tenths changed to 120%, 100%, and 80% of the mid-term plan of the current month after September, showing a declining trend. (From March to August, it is 80%, 100%, and 120% of the mid-term plan, showing an increasing trend).
Second, pay attention to
(1) Even feeding. On-demand production can ensure the continuity of production, but also can solve the problem of uniform feeding, but also reduce costs and improve efficiency, in one fell swoop. Although the amount of daily feed in the first ten days is certain, the actual implementation of the daily feed must be combined with the weather changes on the day. Because the weather changes affect the dissolved oxygen in the water, the dissolved oxygen in the water affects the food intake of aquatic animals. When the aquatic animal is under a certain dissolved oxygen, it is best to eat 7-80% of it every day. Popular speaking: Under certain climatic conditions, eat 7 to 80% full every day, not hunger meal, full meal. It is even feeding.
(2) The combination of compound feed and natural bait. In the feeding process, if the natural food habits of aquatic animals are neglected, they are prone to nutritional deficiency and have a strong stress response. When the weather is mutated, Tongkou, which is fed with artificial compound feed, is susceptible to disease. Although the compound feed is fresh, palatable and nutritious, there are also deficiencies. If the combination of the two can be used to make up for short, it will help fish growth and improve immunity. Therefore, when feeding, it is most suitable to meet the needs of nutrition. Feeding is fast and grows fast. Feeding in this way generally does not produce nutritional deficiencies.
(3) Reasonable. According to the changes in the weather, timely adjustments were made to the amount of feed, and there was a phenomenon of “satisfaction with food†in the production. The reason was that the consumption of oxygen was increased after the aquatic animals had ingested food. The feed in the abdomen was more difficult and lower than the oxygen content in the aquatic animals without feed. The difficulties. Under specific dissolved oxygen, fish eat 7-80% daily is best. Feeding: In order to make sure that the weather is normal and on time, it is less likely to rain in rainy weather, such as sudden thunderstorms in the afternoon or unusually sweltering weather. The last meal can be less or not. The fall in water temperature in the fall requires guarding against overfeeding. If the fish do not emerge on the surface of the cluster, they would rather be temporarily starved and not fed. In addition to reasonable understanding of the amount of feed, we must also pay attention to whether the feed is put in place. For the safe wintering of fish, in the late feeding period (which is near the end of the feeding period), some feeds with higher fat content will be added to increase the accumulation of fat in the body, which will help protect the environment.
