Problems solved by technology

Due to factors such as long-term overfishing, environmental pollution, and environmental conditions suitable for spawning and reproduction, the natural population resources of scorpionfish have declined sharply and cannot meet the market demand.
There have been no reports on the artificial reproduction technology of scorpion, mainly because scorpion has specific living habits and reproductive biology characteristics, and there are broodstock in the artificial breeding of seedlings (broodstock refers to males that have developed to sexual maturity and have reproductive ability. fish or female fish, also called breeding fish) the problem of extremely low rate of artificial induction

Embodiment 1

[0044] Please refer to figure 1 , a device for improving the rate of spawning of broodstock similar to scorpion, comprising an inlet and outlet water circulation pipeline, a container 1 for storing broodstock of scorpion and an oxygenation device 2 for increasing dissolved oxygen in water, and the oxygenation device 2 is connected to the container 1; The cross section of the container 1 is circular;

[0045] The water inlet and outlet circulation pipes include a first water pipe 3, a second water pipe 4, a third water pipe 5 and a fourth water pipe 6, and the first water pipe 3, the second water pipe 4 and the third water pipe 5 are connected to the fourth water pipe 6 respectively. connection; the side wall of the container 1 is provided with a first opening, and the first water pipe 3 communicates with the container 1 through the first opening; the bottom surface of the container 1 is provided with a second opening, and the third The water pipe 5 communicates with the conta...

Embodiment 2

[0052] Please refer to figure 1 In this embodiment, on the basis of Example 1, in order to further better simulate the water flow velocity required to induce labor in the natural environment, so that the oxytocin drugs can play a normal physiological role, further in the second Both the water pipe 4 and the third water pipe 5 are provided with a flow control valve 8 , the third water pipe 5 is connected with a drain pipe, and the drain pipe is provided with a drain valve 9 .

[0053] Certainly, in order to prevent broodstock from entering the circulation pipeline and causing blockage, the water inlet end of the first water pipe 3, the water outlet end of the second water pipe 4 and the water outlet end of the third water pipe 5 are all provided with a fish fence 10; Dead angle, so that the broodstock in the container can be fully stimulated by the water flow, and then ripen. The bottom surface of the container 1 is hemispherical from the center of the container 1, and the seco...

Abstract

The invention relates to the field of fish cultivation, and provides a device and method for increasing the pseudogobio vaillanti parent fish induced spawning rate. The device comprises a water inlet and outlet circulation pipeline, a container for storing pseudogobio vaillanti parent fish and an oxygenation device for increasing the content of dissolved oxygen in water. The oxygenation device is connected with the container. The water inlet and outlet circulation pipeline is connected with the container. A pipeline booster pump is arranged on the water inlet and outlet circulation pipeline. The cross section of the container is in a circular shape. The device has the advantages that by simulating the water flow state of the natural environment needed by pseudogobio vaillanti egg laying, water flow stimulation and ripening acceleration are performed before prenatal diagnosis, drugs for hastening parturition can achieve the normal physiological effect, and the mature rate and the induced spawning rate of the pseudogobio vaillanti parent fish are remarkably increased.

Description

technical field [0001] The invention relates to the field of fish farming, in particular to a device and a method for increasing the rate of spawning of broodstock similar to scorpionfish. Background technique [0002] Pseugobio vaillanti belongs to Cyprinidae, Cyprinidae, Pseudosubfamily, and Pseudogobio genus. It is commonly known as "Magu", "Rougong", "Stick Fish", and "Horsehead Fish". It is widely distributed in my country In the waters of the south, it is a small-scale bottom-dwelling economic fish with flowing water. Although it is small in size, it has a high meat production rate, small intermuscular spines, tender meat, and delicious taste. The market price is high and the demand is large. High fishery value. Due to factors such as long-term overfishing, environmental pollution, and decreasing environmental conditions suitable for spawning and reproduction, the natural population resources of scorpionfish have declined sharply and cannot meet market demand. There ha...
