Problems solved by technology

In addition, when the loach hatches, ventilation is usually required for oxygen supply, but the loach eggs cannot settle during the hatching process. If the sediment accumulates at the bottom, it is easy to cause the loach eggs to stick to each other and cause hatching failure. Therefore, the existing loach hatching devices usually set Conical container 1, aeration tube 2 is set at the bottom of the cone to aerate, so that when the loach eggs sink, they will sink along the inner wall of the conical container, and when they reach the bottom, they will be resuspended by the airflow generated by aeration tube 2
But the problem that it exists is: 1. because the container is conical, so its overall volume is less (conical volume is 1/3rd of cylind

Embodiment 1

[0024] like Figure 1-4 A kind of loach hatching device of the present invention comprises a barrel-shaped hatching container 3, and a circular aeration device is installed in the barrel-shaped hatching container 3; 1 / 3-3 / 5 of the diameter of the incubator container 3; the aeration device is connected with an air intake pipe 5, and the air intake pipe 5 is connected with an air intake pump 6 and a heater 7; a tap water pipe 8 is installed above the barrel-shaped incubator container 3; The hatch container 3 top is equipped with changing water outlet pipe 9, and the bottom is equipped with cleaning outlet pipe 10, and cleaning outlet pipe 10 is equipped with valve 4; Running water pipe 8 is relatively installed with changing water outlet pipe 9.

[0025] Filter cover 22 is used to prevent loach ovum or loach seedling from being changed when changing water, and it has increased the base area with water, and suction is excessive when preventing from changing water.

Embodiment 2

[0036] The aeration device is an aeration pan 19, and a number of aeration holes 20 are formed on the top of the aeration pan 19; the aeration holes 20 are arranged obliquely from the middle to the outside, and the inclination angle of the aeration holes 20 is 3-15°. Preferably it is 5°. like figure 2 As shown, the oblique setting of the aeration holes 20 makes it easier to form a circulation, so that the loach eggs flow with the circulation to prevent their sedimentation and accumulation, and the volume of the barrel-shaped hatching container can be enlarged, so that it is not easily affected by the external temperature, and it is easy to keep the inside of the barrel-shaped hatching container. Keep the temperature of the water in the hatchery stable.

[0037] A first arc-shaped block 11 is formed on the inner side of the bottom of the barrel-shaped hatching container 3, and a second arc-shaped block 12 is fixed on the outside of the aeration device. It is more conducive t...

Abstract

The invention discloses a loach hatching device and method. The device comprises a barrel-shaped hatching container, and a circular aeration device is installed in the barrel-shaped hatching container; the aeration device and the barrel-shaped hatching container are coaxially arranged, and the diameter of the aeration device is 1/3 to 3/5 of the diameter of the barrel-shaped hatching container; the aeration device is communicated with an air inlet pipe, and the air inlet pipe is communicated with an air inlet pump and a heater; a tap water pipe is arranged above the barrel-shaped hatching container; a water changing outlet pipe is mounted at the upper part of the barrel-shaped hatching container, and a cleaning outlet pipe is mounted at the bottom of the barrel-shaped hatching container, and a vale is mounted on the cleaning outlet pipe; and a filter cover covers the water changing outlet pipe. According to the invention, the barrel-shaped hatching container is adopted, the coaxial aeration device with a small diameter is arranged, so that the aeration device can push water in the barrel-shaped hatching container to form circulation, the water amount in the container is increased,more loach eggs can be hatched, the temperature of the internal water is easier to maintain, the suspension state of the loach eggs is maintained, and the probability of friction between the eggs andthe container wall is reduced.

Description

technical field [0001] The invention belongs to the field of breeding, and in particular relates to a loach hatching device and method. Background technique [0002] When the loach hatches, the temperature requirement is very high. It needs to be hatched within 25-30 hours at a temperature of 18-25°C. Too early or too late will cause the loach to be deformed. In addition, when the loach hatches, ventilation is usually required for oxygen supply, but the loach eggs cannot settle during the hatching process. If the sediment accumulates at the bottom, it is easy to cause the loach eggs to stick to each other and cause hatching failure. Therefore, the existing loach hatching devices usually set Conical container 1, aeration tube 2 is set at the bottom of the cone to aerate, so that when the loach eggs sink, they will sink along the inner wall of the conical container, and when they reach the bottom, they will be resuspended by the airflow generated by aeration tube 2 . But the...
