In winter, the water temperature is low, the fish stocking density is high, and the oxygen consumption is increased, which can easily lead to hypoxia in overwintering fish pond waters and affect the survival rate of overwintering fish. The fish farmers can take the following measures to supplement oxygen to the fish pond.

Mechanical Oxygen 1. Recirculating water injection: Two adjacent fish ponds are connected at one corner with a concrete pipe, and the other corner pump is used to pump water from one pool to another pool, so that the water in the two fish ponds can be circulated to increase the water-soluble oxygen in the pool. . 2. Inflation oxygen: air pump is used to press air into the inflatable tube laid under water, so that the air can diffuse into the water and increase the dissolved oxygen in the water. 3. Agitate the bottom of the pond regularly: It is favorable for the upper layer of dissolved oxygen to be transported to the lower layer to increase the dissolved oxygen in the lower layer of water. 4. Change water regularly: Changing the water can restore the balance of dissolved oxygen and nutrients in the water body. Choose no wind and sunny weather, change the water in the fish pond, change the water volume from one third to one half of the pool water each time, and the temperature difference between the pool water before and after changing the water can't exceed 3°C.

Biological oxygen supplement 1. Fertilizer water: Infuse water from other fish ponds with more fat water into overwintering fish ponds. There are more phytoplankton in the fertilizer water. Through photosynthesis, the amount of dissolved oxygen in the pool can be increased. 2. Application of organic fertilizer: over 2,000 square meters per 667 square meters of fermented organic fertilizer applied 100 kg to 150 kg, can promote growth and reproduction of plankton, increase water photosynthesis capacity, increase the pool of dissolved oxygen. 3. Sprinkle with quicklime: Sprinkle lime liquor every 20 days or so to clarify the water quality and improve the transparency of the water body, which will help improve the water photosynthesis capacity.

Chemical oxygen supplements regularly splash hydrogen peroxide, calcium peroxide, etc. in small overwintering fish ponds with large stocking densities and small areas, and can rapidly increase the amount of dissolved oxygen in the pool in a short period of time to reduce the occurrence of winter bored pond accidents.

Dehydrated Spinach Powder

Clear bowel and laxative: Spinach powder is rich in oil, which can lubricate the intestines, clean up the garbage in the intestines, and promote intestinal peristalsis.
Relieving phlegm and relieving cough: There are some natural medicinal ingredients in spinach powder, which can eliminate inflammation in the human body, and can dilate the trachea, dilute phlegm, and relieve the symptoms of coughing and phlegm as soon as possible. In addition, spinach seed powder is also a natural Chinese medicinal material. It can enter the lung meridian, relieve lung heat or lung dryness, and also has a certain therapeutic effect on human pneumonia and tuberculosis.
Nourishes qi and blood: Spinach powder is a food with a very high iron content. People can absorb and utilize the trace element iron as soon as possible after eating it, which can meet the needs of the human hematopoietic system for this substance. In this case, human qi and blood The symptoms of loss and anemia can be significantly reduced.

Calcium and bone strengthening: Spinach powder not only contains trace elements iron, but also rich in trace elements calcium and phosphorus, which can meet the needs of calcium and phosphorus in the normal development of human bones. People can directly use spinach seed powder when needed. Consume with boiling water.
