AI Technical Summary
After the eggs are hatched, it is difficult for the fry to be quickly transferred to the seedling cultivation pond, resulting in an increase in the workload of staff. The fry produces a stress response during the transfer process, a high mortality rate, and uneven dissolved oxygen in the water affects the hatching effect.
A Qinling fine scale salmon fertilized egg hatching and seed cultivation device was designed, including circulation components, hatching components and regulatory components. The incubation components are distributed in an annular shape, providing buoyancy through floating blocks, making the opening of the incubation frame float on the water surface, and connecting cables to each incubation frame to prevent collision. The device allows the fish eggs to be incubated in the hatching frame and can be directly removed to allow the fry to continue to be cultivated on the original site to avoid re-transfer.
The concentrated hatching of fish eggs and pressure-free transfer of fry are achieved, which reduces the stress response and mortality of fry, maintains the uniform distribution of dissolved oxygen in the water, and improves the hatching effect.

It is a landlocked cold-water fish that is unique to my country and has a local distribution. Since the 1980s, due to the influence of factors such as the natural environment and human activities, its germplasm resources have declined sharply and are on the verge of extinction. In 1988, it was listed as an endangered species. In recent years, a number of national and provincial nature reserves have been established in the Qinling area, and artificial breeding and seed cultivation of Qinling Slimy Salmon have been actively carried out.
[0003] However, after the fish eggs are hatched into fry, it is difficult to quickly transfer the hatched fry to the fry breeding pond. The staff are required to pick out the fry one by one, which increases the workload of the staff. In addition, different degrees of stress reactions will occur during the transportation process, leading to the death of the fry. In addition, the dissolved oxygen at the water outlet is lower than that at the water inlet, resulting in a lower fry emergence rate in the rear row of hatching frames than in the front row of hatching frames. The oxygen content in different areas of the water is uneven, affecting the hatching of fish eggs. Utility Model Content
[0004] The purpose of the utility model is to provide a device for hatching fertilized eggs of Qinling salmon and cultivating fry, which can be used for centralized hatching and the hatching frame can be directly removed so that the fry can continue to be cultivated in the original site, avoiding the need to transfer the fry to the fry cultivation pond again, causing the fry to have a stress response and lead to the death of the fry, so as to solve the problems raised in the above-mentioned background technology.

[0026] Working principle:
[0027] Step 1: water filling and placement. Water is injected into the water filling pipe 102 through an external water pump. The water filling pipe 102 discharges water into the hatching pool 101 from the right side. Because the inner wall of the hatching pool 101 is arc-shaped, the water is guided to flow in an arc, and a clockwise rotating water flow is generated in the hatching pool 101. When the water level is higher than the drain pipe 103, the excess water will flow to the drain pipe 103 and be discharged from the hatching pool 101. The water level in the hatching pool 101 is maintained, and the hatching frame 201 is placed in the hatching pool 101. The hatching frame 201 is immersed in water. The buoyancy provided by the floating block 203 lifts the mounting plate 202 and the hatching frame 201, so that the opening of the hatching frame 201 floats on the water surface, and the connecting rope 205 is tied to the connecting ring 204. The connecting rope 205 connects each hatching frame 201 and surrounds the drain pipe 103 to prevent collision caused by the scouring of the water flow, and the fish eggs are placed in the hatching frame 201 for hatching.
[0028] Step 2: Observation and control. Connect the power supply to start the oxygen pump 301. The oxygen pump 301 pumps oxygen into the water and generates bubbles. The bubbles rotate and burst in the incubation pool 101 along with the water flow, and the oxygen is evenly diffused into the incubation pool 101. The staff observes the water temperature in the incubation pool 101 through the thermometer 302.
