The rise in temperature during the summer season is a period when the food intake of fish is very strong and growing. It is also a period when the fish is prone to hypoxia and floating hair disease. The following four aspects should be noted in the management of this period: 1, Qintang Tang inspection, anti-floating head. Check the pond 2-3 times a day, look for floating heads before and after the dawn, check the fish's feeding situation in the afternoon, check the day's food and the signs of floating heads at sunset. Prevention of fish floating head method: (1) When there is a fish floating head phenomenon, stop feeding and fertilizing, and start the aerator to increase oxygen. (2) Immediately add water, increase oxygen content in water, and adjust water quality. (3) If the water source is difficult, use 100 kg of yellow mud per acre and 5 kg of salt per acre, or add 2.5 kg of quicklime powder and add water to slurry. 2, diligent decontamination, disease prevention. Frequently remove the residue and remove stem roots. Frequently move the grass rack, clean the food table, sprinkle lime on the table and grass rack, and regularly use drugs to prevent disease. At the same time, pay attention to repel predators such as birds and beasts. 3. Add fresh water and promote growth. As the saying goes: "Deepwater raise fish." The water level of fish ponds is constantly adjusted as the size of the fish body and the season change. Water is often added during the high temperatures and during the summer season when the fish are feeding heavily. Conditional water can be added 4-5 times a month to increase the living space of fish, improve water quality, and promote the growth of fish. 4, summary records. The fish farmers need to make an account for each fish pond, that is, each fish pond has a diary of fish culture. The date, number of tails, specifications, and weight of each species of fish, the date of harvest, the number of tails of each fish, Specifications, weight, daily feeding amount, fertilization type and quantity, and water quality management and fish disease prevention and control should be recorded in order to summarize and accumulate experience, and serve as a reference for future plans and improvement of fish culture techniques. . In addition, during the main growth season of fish, it should be checked frequently. Once abnormal conditions are found, appropriate measures must be taken in time to ensure the healthy and rapid growth of fish.
