[0053] detailed description: Figure 1-Figure 5 A kind of fish egg hatching system based on the live simulation of the river channel shown, comprises a hatching tank 1 that is overall horizontal ring, hatching tank 1 comprises two relative semi-circular segments and two connecting between the two semi-circular segments. The straight section also includes a control and adjustment system, the control and adjustment system includes a temperature control device 14 and an aeration device 15 installed on the hatch tank 1; it also includes a flow rate adjustment device, and the flow rate adjustment device includes a set in the hatch tank along the cross-sectional direction The push plate 2 is connected to the circular motion control mechanism and can be driven to perform circular motion along the circular motion of the hatching tank.

[0054] In this way, the present invention can not only control the temperature and oxygen content of the water body to make it converge with the actua...

Abstract

The invention discloses a roe hatching system based on river live simulation. The roe hatching system is characterized by comprising a hatching tank integrally in a horizontal annular shape, the hatching tank comprises two opposite semi-annular sections, two linear sections connected between the two semi-annular sections and a control adjusting system, and the control adjusting system comprises a temperature control device and an aeration device which are mounted on the hatching tank; and the roe hatching system further comprises a flow rate adjusting device, the flow rate adjusting device comprises a push plate located in the hatching tank and arranged in the cross section direction, and the push plate is connected with a circulating motion control mechanism and can be driven to perform circulating motion in the annular shape of the hatching tank. The roe hatching system based on river live simulation has the advantages that the water environment can be better adjusted, and the fish roe hatching effect is improved.

Description

technical field [0001] The invention relates to the technical field of hatching and cultivating fish eggs, in particular to a fish egg hatching system based on live river simulation. Background technique [0002] Floating fish eggs refer to fish eggs that have a density similar to that of water, are non-viscosity, are separated from each other, and are fertilized and then float with the water to complete hatching, such as eggs produced by herring, grass carp, silver carp, and bighead carp. The hatching process of fish eggs is of great significance to fish reproduction. It not only directly affects the number and health of larvae, but also affects the amount of fish resources and the survival of species. It takes dozens or even hundreds of hours for floating fish eggs to develop from fertilized eggs to young fish capable of swimming. This distance can reach hundreds of kilometers in natural water bodies such as the upper reaches of the Yangtze River. Therefore, the research ...
