Chase fertilizer material. Fertilization is the need to fertilize water quality, cultivate natural foods, and ensure the feeding of pond fish. All types of fish ponds, especially fish ponds based on flowering whitefish, should be properly chased. Due to the hot summer weather, high water temperature, rapid decomposition of organic matter, reproduction of plankton, fish consumption of oxygen, and water quality deterioration, so the amount of fertilizer should not be too much, adhere to the principle of a small amount of ground, and according to the weather, color and cultured fish The variety to determine the amount of fertilizer. If the weather is fine, it can be applied in an appropriate manner. Apply little or no fertilizer on rainy or sweltering days. The water is light, light yellow or light green, and the transparency is high. To use it more, the water is brown-green, oil-green or red-brown, and the transparency is 30 cm. Around, you can use less or no fertilization; fish ponds that use oysters, clams, and squid should be used in multiple applications, and fish ponds that use mainly cyanotic fish or grass carp should be used sparingly. Fertilizer to avoid the food market.

Feed feed. Feed intake from July to September should account for 60% of the total annual feeding amount, and it should be fed 3 times a day in the early, middle and late nights. The amount of morning and evening is bigger and the amount is smaller at noon. The combination of early green material, medium fine material, and late green material is required, and the amount of feed to be fed should be fresh and appropriate. Feeding on a fixed food field, and encountering hot days, rainy days or fish floating heads, should be fed little or no.

Strengthen management. Check the pond daily morning and evening to observe the dynamics of the color and fish and master the specific changes in the pond. If abnormal, take appropriate measures in time to prevent fish disease. Frequently remove leftovers and dirt, remove pool side weeds, so as not to pollute water quality, affect the amount of dissolved oxygen in water.

Improve water quality. To regularly add new water, increase dissolved oxygen in water, generally add water every 2 to 3 days, each time adding 5 to 10 cm of water to prevent fish from floating. Water injection time: In normal weather conditions, water injection into the fish pond at night can increase the amount of dissolved oxygen in the pool water, improve water quality, and avoid fish's hypoxia floating head. Water flow plate: New water is added to the fish pond. If the water stream falls directly from a height and rushes into the bottom of the pool, the feed residue, excrement, sludge, etc. deposited on the bottom of the pond will be deposited due to the large amount of water flow and water. Overturned. In order to prevent this from happening, a fixed wooden board can be placed under the water in the tribe to make the injected new water fall on the board and splashes of water to increase the amount of dissolved oxygen injected into the new water.

Increase dissolved oxygen. When it is predicted that a fish floating head may occur, the water pump is used to add water or the aerator is used to increase oxygen, and at the same time, the fertilization is stopped and the feeding amount is controlled, thereby shortening the eating time. When fish floating head occurs, if there is no oxygenating device or there is no time to increase oxygen, yellow muddy water can be added to the pool to add salt water, that is, 10 kg of yellow mud per acre of water surface, add water to make a paste, and add 10 kg of salt solution in water Sprinkle the entire pool after mixing. The start time of the aerator: Sunny at noon boot, cloudy early morning boot, rainy night boot, do not boot in the evening.

Prevent fish diseases. Every 15 days or so, 250-300 g of bleaching powder and 125 g of ferrous sulfate are sprayed on the side of the fish pond and on the food table to sprinkle the water once to prevent bacterial skin disease and gill disease; , press 10 kilograms of fish with 500 grams of garlic, chopped and chopped feed, each feeding for 3-5 days, can prevent diseases such as enteritis; every 20-30 days, with 15-20 kilograms of lime per acre surface, soluble Spilled water can improve water quality.
