At present, it is particularly important for high-temperature and rainy weather to feed feed properly. Experts from Jiangsu Province's Lushui Fisheries Technology Promotion Station reminded the majority of aquaculture demonstration households and radiating households that feed feeding should comply with “reasonable, appropriate, timely, and appropriateâ€. To prevent the dehydration of water bodies caused by overfeeding of feeds or deterioration of feeds, fish floating phenomenon occurs.
One is to master feeding standards. Feeding during the high temperature period accounts for 3% to 4% of the total fish weight, but leftovers should be prevented.
The second is to distinguish breeds. Different kinds of fish have different potential growth and nutrient requirements for growth during the high temperature period, so their feeding amount should be different from the feed variety.
The third is to grasp the feeding period. The high temperature period is generally better than feeding 70%. Select fixed-point feeding observations, generally depending on the feeding situation 1 to 2 hours after feeding. After 1 hour of eating, it indicates that the food is to be fed, and 2 hours have not been eaten yet. It should be appropriately reduced. If the fish is fed regularly for a longer period of time, the time for eating the fish suddenly decreases to 2 hours, indicating that the fish has gained weight and the feeding standard should be adjusted.
The fourth is to watch the pond water color. The general fertilizer is oily green or yellow-brown, with lighter water in the morning and thicker in the afternoon. The transparency of the water is about 30 cm, indicating that the fat is moderate and can be fed normally; when the transparency is more than 40 cm, the water quality is too thin and the feeding amount should be increased; when the transparency is less than 20 cm, the water quality is too fat, the feeding should be stopped or reduced. .
Fifth, pay attention to reasonable operation. Feeding attention Do not pour the feed into the pool at one time, so as to avoid dissolving nutrients and causing waste or water quality. Feeding the feed and domesticating should grasp the rhythm of “slow and fast one slow†and “less one more and one less†feeding quantity, a few times in order to improve the feeding effect. In low-oxygen periods such as cloudy days and rainy seasons, feed as little or as little as possible to prevent flooding or wasting feed. Nongbo.com
