Dace pond overwintering method

Abstract

The invention discloses a dace pond overwintering method which comprises the following steps: S1, pond constant temperature; S2, food feeding; S3, internal oxygen supply; and S4, internal heat dissipation. A pond is sealed in winter, water is circularly heated, the situation that dace has stress reaction due to uneven water temperature caused by a single heating position is avoided, oxygen is increased through an oxygen pump, the situation that the dace dies due to insufficient dissolved oxygen during sealing is avoided, in a sealed feeding mode, opening of the pond during feeding is avoided, meanwhile, the feeding speed and time can be stably controlled, the optimal feeding effect is guaranteed, meanwhile, heat dissipation is reduced to the minimum, and the internal constant temperature is guaranteed; and meanwhile, in summer, a protective ventilation plate and a transparent heat preservation plate can be opened, internal heat dissipation is guaranteed, and therefore the situation that the growth of the dace is affected by too high temperature is avoided.

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
