Sharing Daily Management Experience in Freshwater Pompano Farming
1. Bait varieties One type is directly fed with Northeast soybeans. The other type is fed with pellet feed, with a protein content of more than 32%; the later-stage feed should increase the fat content. 2. Feeding method The feeding method for soybeans is to inspect the pond more than three times a day and add more as soon as they are eaten, with the daily feeding amount based on the principle that it is eaten within 24 hours. Pellet feed is fed with a feeder. After the fingerlings are stocked, sufficient bait should be fed according to conditions such as weather and water temperature. Especially in June, when the water temperature rises and the fish gain weight, the feeding amount should be increased at the right time. The feeding amount should be controlled on the principle that the fish are full and no fish are competing for feed in front of the feeder. 3. Daily management After the fingerlings are stocked, pay attention to changes in water quality. In the early stage, add water once every half month. In June, the fish eat more and excrete more, and water quality is prone to deterioration, so add water once a week, 20 cm each time, and keep the pond water color "fertile, lively, tender, and refreshing." Start the aerator at the right time. In the later stage, the fish load in the pond increases. When the weather changes, start the aerator early to prevent fish from gulping air at the surface. Patrol the pond frequently and inspect frequently so as to discover problems in time and understand the fish's feeding situation. 4. Fish disease prevention and control In the mixed-culture pond, on April 25, before stocking freshwater pompano, kill parasites and disinfect. The main disease during the farming process is enteritis. Soaking soybeans in florfenicol or mixing it into pellet feed and feeding for three days can take effect. 5. Harvest Freshwater pompano is easy to catch. With the first seine haul, 90% of the pond can be caught, and after two more seine hauls, the pond can basically be caught clean.
