Description

Technical Field

[0001] The utility model belongs to the technical field of fish artificial propagation, and more specifically relates to a sturgeon fertilized egg hatching device. Background Art

[0002] Sturgeons are hard-scaled fish and one of the oldest fish species in the world. Known as "living fossils," they possess significant economic and scientific research value. Sturgeons are large, take a long time to mature, and are difficult to artificially propagate. Their fertilized eggs are large (2-4 mm), sink, and are sticky. They require suitable water temperatures, sufficient dissolved oxygen, and a constant flow for normal development. During incubation, untimely stirring or improper handling often leads to accumulation of fertilized eggs, resulting in localized hypoxia and the growth of water mold, which affects hatchability.

[0003] Currently, sturgeon eggs are often hatched using specialized incubators, such as the Yushchenko and McIntyre incubators. These incubators are complex to manufacture, install, and operate, requiring significant labor and time. These devices are expensive and unsuitable for large-scale deployment. Therefore, a low-cost, easy-to-operate device suitable for sturgeon hatching is highly desirable. Utility Model Content

DETAILED DESCRIPTION

[0022] The technical solution of the present invention will be further described below with reference to the accompanying drawings and through specific implementation methods.

[0023] Example 1

[0024] See also Figure 1 The utility model provides a sturgeon fertilized egg hatching device, comprising a breeding barrel 1 and a hatching frame 5, wherein the hatching frame 5 is placed inside the breeding barrel 1, a top water supply pipe 6 is provided directly above the breeding barrel 1, and a first water spray hole 8 is provided on the top water supply pipe 6; a bottom water supply pipe 7 is provided inside the breeding barrel 1, and the bottom water supply pipe 7 includes a suspended water inlet section, a vertical water inlet section and a parallel water inlet section attached to the bottom of the breeding barrel 1, which are connected in sequence; a second water spray hole 10 is provided on the parallel water inlet section;

[0025] The incubation frame 5 is made of wood.

[0026] In the above technical solution, after water is put into the breeding barrel 1, the wooden hatching frame 5 floats on the water surface. Half of the hatching frame 5 floats on the water surface and half is underwater. It can rotate around the breeding barrel 1 under the action of water flow; the top water supply pipe 6 supplies water from the top of the breeding barrel 5. A row of first water spray holes 8 are provided on the pipe, and the water spray direction is downward to the left and forms a certain angle with the water surface (such as Figure 1 As shown); after the bottom water supply pipe 7 is connected to the external water source, a section of water pipe is first suspended on the breeding barrel 1, and then a section of water pipe is set vertically downward from the breeding barrel 1. Finally, a section of water pipe is set through an elbow and parallel to the bottom of the breeding barrel 1, that is, it is composed of a suspended water inlet section, a vertical water inlet section and a parallel water inlet section; similarly, the parallel water inlet section on the bottom water supply pipe 7 is provided with a row of second water spray holes 10, which spray water vertically upward at the bottom of the breeding barrel 1, forming an overall disturbance with the water flow stirred up by the first water spray holes 8.

[0027] In some embodiments, a water level control structure is further provided in the middle of the aquaculture barrel 1. The water level control structure can be composed of a water level control station pipe 2 and a drainage sleeve 3 coaxially arranged on the periphery of the water level control station pipe 2. The water level control station pipe 2 is connected to a small hole opened in the bottom of the aquaculture barrel 1; the drainage sleeve 3 is provided with a drainage hole 4. That is, the water level control station pipe 2, the drainage sleeve 3, and the liquid level of the aquaculture barrel 1 are maintained in communication through the drainage hole 4. When the liquid level exceeds the top of the drainage sleeve 3, water will flow out of the drainage sleeve 3 through the small hole opened in the bottom of the aquaculture barrel 1, thereby regulating the liquid level and preventing it from rising too high. The opening and sealing of the small hole in the bottom of the aquaculture barrel 1 are general skills mastered by those skilled in the art.

[0028] As the preferred technical solution of this embodiment, the breeding barrel 1 is made of fiberglass, with a diameter of 200 cm and a depth of 50 cm.

[0029] As a preferred technical solution of this embodiment, the diameter of the water level control station pipe 2 is 7.5 cm.

[0030] As the preferred technical solution of the present embodiment, the hatching frame 5 is 50 cm long, 50 cm wide, and 15 cm high, and is provided with an 80-mesh screen at the bottom. This arrangement facilitates the penetration of water flow, stirs the fertilized eggs, and avoids hypoxia.

[0031] As a preferred technical solution of this embodiment, the diameter of the top water supply pipe 6 is 3.2 cm.

[0032] As a preferred technical solution of this embodiment, the diameter of the bottom water supply pipe 7 is 3.2 cm.

[0033] As a preferred technical solution of this embodiment, a first valve 9 is further provided on the top water supply pipe 6 to adjust the water flow.

[0034] As a preferred technical solution of this embodiment, a second valve 11 is further provided on the suspended water inlet section to adjust the water flow.

[0035] The working principle of this utility model:

[0036] A hatching frame 5 is placed in a culture barrel 1, and fertilized sturgeon eggs are placed in the hatching frame 5. Water is turned on, and a top water inlet pipe 6 sprays water toward the lower left through a first water spray hole 8, forming a counterclockwise water flow in the culture barrel 1. Under the action of the water flow, the hatching frame 5 rotates around a centrally arranged drainage sleeve 3. The bottom water inlet pipe 7 sprays water upward through a second water spray hole 10, forming an upward water flow. When the hatching frame 5 rotates above the second water spray hole 10 with the water flow, the fertilized sturgeon eggs placed in the hatching frame 5 are flipped by the upward water flow. The fertilized sturgeon eggs are flipped once each time the hatching frame 5 rotates around the barrel. The water spray volume of the first water spray hole 8 is adjusted by a first valve 9, thereby adjusting the counterclockwise water flow speed, and then adjusting the rotation speed of the hatching frame 5 around the barrel. The water spray volume of the second water spray hole 10 is adjusted by a second valve 11, thereby adjusting the flipping amplitude of the fertilized sturgeon eggs placed in the hatching frame 5. This can effectively prevent local hypoxia caused by accumulation of fertilized eggs and damage to the fertilized eggs caused by continuous flipping.

[0037] At the same time, through the structural design of the water level control station pipe 2 and the drainage sleeve 3, the water level height can be effectively adjusted to avoid overflow due to excessive water level.

[0038] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any modifications or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
