A kind of dace pond overwintering method

Abstract

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.

Description

technical field [0001] The invention relates to the technical field of fish farming, in particular to a method for overwintering dace ponds. Background technique [0002] Mud carp, commonly known as mud carp and dace male, belongs to Cyprinidae, Cyprinidae, Dace subfamily, and genus Dace. Dace is an omnivorous fish that feeds on pond zooplankton, organic debris, and feces. It plays the role of "scavenger" and increasing production and efficiency in breeding. The main production area of ​​dace is in China. It is more common in areas with high water temperature such as the Pearl River Delta and Hainan. The cost of breeding is low and the output is large. Dace is an important economic fish and pond in the south. One of the breeding objects, artificial breeding is generally carried out intensively through artificial ponds. [0003] However, at present, when the dace are intensively cultured, the heating rods are generally used to directly heat the heat preservation in winter, b...

AI Technical Summary

Problems solved by technology

[0004] The present invention provides a method for surviving the winter in ponds of dace, which can effectively solve the above-mentioned problems in the background technology. At present, when the mud carp is intensively cultured, heating rods are generally used to directly heat the heat preservation in winter, but the single heating method leads to insufficient heating. Even and not sealed, resulting in faster water heat dissipation, unable to maintain a constant temperature environment
