Summer is the golden season for fish growth. Summer is also the season when water quality is easy to change and diseases are high and prevalent. Therefore, the scientific management of ponds is also particularly important. What should I pay attention to when raising fish in ponds in summer? What is the best time to feed the fish in the fish pond in summer?

What should I pay attention to when raising fish  in ponds in summer?

What is the best time to feed the fish in the fish pond in summer

1. Fertilization

Summer is the period of feeding amount, and it is also the period of vigorous growth of fish and high oxygen consumption. The application of organic fertilizer is not recommended, but inorganic fertilizer should be used to reduce the pollution of pool water. The specific amount of fertilization is determined according to the pond water fertility, water quality and weather conditions. Generally, the transparency of the pool water should be kept at about 25 cm, and the color of the water should be tea-brown, green-brown, yellow-green or oil-blue. The fertilization time is generally chosen to sprinkle the whole pool in the morning on a sunny day. Due to the increase of nitrogen content in the water in summer, water-soluble phosphate fertilizer should be selected when fertilizing. Generally,superphosphate  is applied 2 to 3 times a month, and the dosage is 5 to 6 kg per mu each time. Usually 3 to 5 days after the application of phosphate fertilizer , the phytoplankton in the pool will peak and the ammonia nitrogen content will drop. At this time, according to the requirements of water quality management, new water should be added appropriately to prevent the water color from being too thick.

2. Adjust the water quality

Regularly adding new water can bring in oxygen and nutrients such as iron, manganese, and silicon that are lacking in the water, and can also dilute the organic matter in the pool water and the toxic substances metabolized by animals, thereby restoring the balance of the ingredients in the pool water. Generally, the fish pond should be filled with new water 3-4 times a month, about 30 cm each time.

3. Baiting

It is better to feed 80% full in summer. If you feed too much, due to the high water temperature, the residual bait will rapidly deteriorate the water quality, and the pathogenic bacteria will multiply and cause various fish diseases. If the fish eat too much, they are also prone to enteritis. The specific feeding amount should be flexibly controlled according to the weather, water temperature, water quality and fish feeding situation.

4. Anti-floating head

To prevent floating heads, it is necessary to patrol the pond frequently, check whether there are floating heads before and after dawn, check the feeding situation of fish in the afternoon, and check the eating conditions of the whole day and whether there are signs of floating heads at sunset. Anti-floating head to maintain good water quality. Reduce the storage of fish in the pond. For fish ponds with frequent serious floating heads, part of the fish should be caught and marketed in time. If the water quality of the pond is thick and the plankton reproduces excessively, some medicines should be used to kill some of them to reduce the consumption of dissolved oxygen in the water. The method of fish floating head rescue:

1. Immediately inject new water to increase the oxygen content in the water.

2. Start the aerator to increase oxygen and stop feeding and fertilizing.

3. Use 10kg of yellow mud and 20kg of salt per mu , add water, mix well and sprinkle over the whole pool, or 2.5kg of quicklime powder , add water to make a slurry, and sprinkle the whole pool for first aid.

5. Prevention and control of fish diseases

Summer is the season when fish diseases are prone to occur, so it is necessary to do a good job in the prevention and control of fish diseases.

1. Disinfection: including pre-disinfection of fish ponds, disinfection of fingerlings before stocking, and disinfection of water bodies.

2. Careful operation in fishing, transportation, stocking and other activities to prevent fish injury.

3. Take effective measures in time for symptomatic treatment when fish diseases are found. The order of medication should be correct. Generally speaking, insecticides should be killed first and then sterilized.

What is the best time to feed the fish in the fish pond in summer?

1. Fish ponds generally need to be fed two to four times a day, the earliest one should not be earlier than 9:00 in the morning , and the latest one should not be later than 5:00 pm .

2. The amount of food fed should also be controlled. After each feeding, it should be eaten within 30 minutes. If there is any residual bait, it should be removed as soon as possible.

3. If you encounter continuous rainy weather, you need to wait until the weather is clear before feeding.

4. In addition, according to the different feeding habits of fish, the choice of feed is also different.
