1. Gradually increase the height and stabilize the water at a high level, maintaining a transparency of 25 cm or more. At the same time, maintain a good pool, clean up the channels around the pool. Reduce the weather, external water sources, rainwater, change the range of water quality and water temperature in the pool, and reduce the emergency response of aquaculture products. At the same time, the amount of fish per unit of water is reduced, and the space for aquaculture products is increased. When adding water before and after adding water, pay close attention to changes in the water quality of the water source and the pond, and the activities of the aquaculture product.
2, to ensure feed quality. Nutrition is comprehensive, fresh and mildew-free. The amount of bait should be increased or decreased according to the weather and the fish in the pool, and can maintain 8-90% of the fullness of the aquatic product when it is eaten. Adhere to regular positioning and feeding. The feed protein content may be slightly lower, and for omnivorous aquaculture products, the plant feed may account for 60%. However, it is advisable to purchase it in small quantities to prevent mildew.
3, timely removal of floating plants in the pool, residual food and other debris, remove the poolside weeds. If you are close to farmland, you should clear the packaging containers containing pesticides to prevent contamination of the aquaculture waters.
