The invention discloses a method for overwintering dace ponds, S1: pond constant temperature, S2: food feeding, S3: internal oxygen supply, S4: internal heat dissipation, by sealing the pond in winter and heating the water in a circular manner , to avoid the stress response of the mud carp due to uneven water temperature caused by a single heating position, increase oxygen through the oxygen pump, and avoid the death of the dace due to insufficient dissolved oxygen during sealing, and through the sealed feeding method, It avoids the need to open the pond when feeding. At the same time, it can stably control the speed and time of feeding, ensuring the best feeding effect, and at the same time reducing heat dissipation to a minimum, ensuring a constant internal temperature. At the same time, it can be opened in summer. The protective ventilation panel and transparent insulation panel ensure the internal heat dissipation, so as to avoid the situation that the growth of dace is affected by excessive temperature.
