CATDOLL : CATDOLL: How to breed yellow bone fish during winter

Method of breeding yellow bone fish during winter

1. Increase the water level of the pond

During the winter, the water temperature continues to drop. At this time, it is necessary to choose sunny weather to increase the water level in the pond in time to help maintain the water temperature of the pond. The lower the water temperature, the stronger the clustering of yellow catfish. Too shallow water level and too low water temperature will make yellow catfish gather more compactly in small pits during the winter. Yellow catfish is a scaleless fish with three hard spines on its body. When they gather together compactly, they are easy to pierce each other's skin, form wounds, and be infected with water mold. In winter, the water level of the pond is generally kept at about 2m. If the water level is too shallow, it is not easy to maintain a stable water temperature. If the water level is too deep, it is easy to cause hypoxia in the water at the bottom of the pond.

2. Fertilizer and water for wintering

Farming experience shows that the fertility of the water directly affects the health of catfish during the winter. In ponds where the water is kept at a good fertility during the winter, catfish are not prone to diseases. In ponds where the water is clear and moss grows during the winter, catfish are prone to serious diseases such as water mold and rot, and may even be wiped out. During the winter, catfish should maintain a good fertility, good algae color, and a transparency of 25 to 30 cm. According to the fertility of the water, choose sunny weather to spray biological fertilizers, organic fertilizers and other water fertilizer products from time to time.

3. Regular disinfection and bottom modification

During the winter, catfish rarely feeds, rarely turns on aerators, and never changes water, which can easily cause water aging, breed harmful bacteria at the bottom of the pond, deteriorate the habitat of catfish at the bottom of the pond, and easily cause catfish to suffer from skin rot and other diseases. It is required to disinfect or change the bottom once every month or so during the winter of catfish, and disinfection and bottom change should be carried out alternately.

4. Turn on the oxygenator at the right time

During the winter, the water temperature is very low, the upper and lower water bodies are stratified, and the toxic and harmful substances such as ammonia nitrogen, nitrite, and hydrogen sulfide in the bottom water body are not easy to spread, and the water quality environment at the bottom of the pond deteriorates. In traditional aquaculture wintering management, aerators are rarely turned on, which is one of the misunderstandings of wintering management. It is necessary to turn on the aerator in a timely manner when the weather is fine to increase the exchange of upper and lower water layers. Through the aeration effect of the aerator, some toxic and harmful substances are volatilized into the air, activating the pond water quality and creating a better pond bottom water quality environment.

5. Keep patrolling the pond

In winter, the water temperature is low at the top and high at the bottom, and reverse stratification occurs. Yellow catfish cluster and stay at the bottom. Under normal circumstances, no fish activity can be observed, which can easily make people numb. In fact, the rate of dissolved oxygen decline in winter is relatively slow, unlike the sudden change in summer, but gradually. Therefore, insist on patrolling the pond at noon every day, carefully observe the activities of fish under the water layer, and take timely measures when problems are found. Pay special attention to observation when patrolling the pond, and measure the dissolved oxygen content of the pond water regularly. Solve problems in time when they are found. General remedial measures include installing a submersible pump to circulate the pool water and starting an aerator.

6. Feed as early as possible

When breeding yellow catfish, farmers often start feeding in late March or even mid-to-late April due to lack of experience. In the actual breeding production process, it is found that yellow catfish can still eat a small amount of food when the water temperature is 5-8℃. Therefore, from late February to early March every year, it is necessary to start feeding in small amounts and gradually lure the yellow catfish to the feeding table for centralized feeding. Starting feeding early and minimizing the time of stopping feeding will help the yellow catfish recover as soon as possible and reduce the possibility of death after the beginning of spring.
