Embodiment Construction
[0014] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0015] The structure of the sturgeon fertilized egg hatching device of the present invention, as figure 1 As shown, it includes a water storage tank 6, the water storage tank 6 is connected to the water pump 7, and the water water pump 7 transports the water in the water storage tank 6 to the hatching tank 2 through the water inlet pipe 1, and the hatching tank 2 is connected to the water outlet pipe 5, and the water outlet pipe 5. Lead the water flow into the reservoir 6. In the specific implementation process, combined with the attached figure 1 It can be seen that choosing a structure in which multiple hatching tanks 2 are connected in parallel is an optimized structure for industrialization, so that the resources of the sturgeon fertilized egg hatching device can be fully utilized.
[0016] Such as figure 2 As shown, the water inlet of...

The invention discloses a sturgeon fertilized egg hatching device. The sturgeon fertilized egg hatching device comprises a hatching tank, wherein the top of the hatching tank is connected with a waterinlet pipe; a water outlet pipe is arranged on the bottom of the hatching tank; a movable supporting frame is arranged in the hatching tank; a hatching frame is arranged on the movable supporting frame in a matched manner; the water inlet pipe is connected with a water suction pump; the water suction pump is connected with a water storage tank; and the water outlet pipe is connected with the water storage tank. By the sturgeon fertilized egg hatching device, the problem that the hatching rate of an existing sturgeon fertilized egg hatching device is low is solved. The sturgeon fertilized egghatching device can be applied to industrial sturgeon breeding, breeding water is saved, sturgeon fertilized eggs are suspended by water flow, sufficient dissolved oxygen is provided for a fertilizedegg hatching process, embryonic development is promoted, waste generated by metabolism of embryos is taken away in time, the waste is conveyed back to the water storage tank through the water outlet pipe, water treatment is carried out, water cleanness is maintained, effective hatching of the sturgeon fertilized eggs is met, and the hatching rate is high.
Description
technical field [0001] The invention belongs to the technical field of fish farming, and in particular relates to a hatching device for fertilized eggs of sturgeon. Background technique [0002] Sturgeon is a large migratory fish of the order Asteroides. my country is one of the countries with the most species of sturgeon, the widest distribution and the richest resources in the world. Due to the relatively large size of the fertilized eggs of the sturgeon, the conditions for the hatching of the fertilized eggs are relatively harsh, and there must be sufficient oxygen and flowing water at a certain flow rate. few. At present, most of the sturgeon hatching devices used by the majority of fish farmers are old-fashioned incubators designed by the former Soviet Union. The invention discloses an effective hatching device for fertilized eggs of sturgeon that can meet the demands of numerous fish farmers. Contents of the invention [0003] The object of the invention is to pro...
