Problems solved by technology

In addition, due to Tibet's special geographical environment, fragile ecological environment, simple ecosystem structure, and the characteristics of plateau fish with slow growth, late sexual maturity, low fecundity, long resource replenishment cycle, and high adaptability and dependence on habitats, plateau fish Humans are extremely sensitive to changes in the ecological environment, and once their resources are damaged, it will be extremely difficult to recover

Embodiment 1

[0031] like figure 1 , figure 2 , Figure 5Shown, a kind of Tibet Plateau Schizothorax seed breeding system comprises fishpond 11, and the water outlet of described fishpond 11 connects water treatment system 9 and dissolved oxygen device 10 successively through pipeline, and dissolved oxygen device 10 is connected with described fishpond 11 through pipeline. The water inlet is connected, the water outlet is set opposite to the water inlet, and the bottom surface of the fish pond 11 is a slope where one end of the water inlet is higher than the one end of the water outlet; the dissolved oxygen device 10 includes a housing 1 and a liquid inlet arranged in the housing Chamber, air inlet chamber, diffusion chamber 7 and mixing chamber 8, the liquid inlet chamber is composed of the liquid inlet channel 2 and the first injection chamber 3 connected to the liquid inlet channel; the first injection chamber 3 is trumpet-shaped, with an opening The small one end is the first liquid ...

Embodiment 2

[0036] This embodiment is on the basis of embodiment 1:

[0037] Such as image 3 As shown, the inner wall of the mixing chamber 8 is provided with a deflector 81 from the liquid inlet to the liquid outlet. The deflector 81 is helical and the helix angle is consistent with the inclination angle of the liquid outlet.

[0038] After the flowing water flows out of the liquid outlet hole 712 and is accelerated, a swirling flow is generated in the mixing chamber 8, and a spiral deflector 81 consistent with the inclination angle of the liquid outlet hole is added in the mixing chamber 8 to make the water body more stable in the mixing chamber The ground swirling flow ensures that the air bubbles are more fully mixed in the water body.

Embodiment 3

[0040] This embodiment is on the basis of embodiment 1:

[0041] Such as image 3 As shown, the inner wall of the mixing chamber 8 is provided with a deflector 81 from the liquid inlet to the liquid outlet. The deflector 81 is helical and the helix angle is consistent with the inclination angle of the liquid outlet.

[0042] Such as Figure 4 As shown, two steam holes 42 penetrating through the casing are oppositely arranged on the side wall of the air intake channel 4 , and the steam holes 42 communicate with external solar steam equipment.

[0043] When the water temperature in the fish pond is lower than the required value, low-temperature water vapor enters the water body, and the heat released by liquefaction can achieve the effect of warming; steam and oxygen can also be introduced at the same time, and the bubbles integrated into the steam continue to liquefy and release heat during the floating process , and the bubbles can stir the water body to achieve the effect o...

Abstract

The invention provides a breeding system of schizothorax seedlings in the Tibet plateau. The system includes a fish pond, wherein a water outlet of the fish pond is sequentially connected with a watertreatment system and a dissolved oxygen device through pipelines, the dissolved oxygen device is connected with a water inlet of the fish pond through a pipeline, the water outlet is opposite to thewater inlet, a bottom surface of the fish pond is a slope of which one end of a water inlet is higher than one end of a water outlet, the dissolved oxygen device includes a casing and a liquid inlet chamber, an air inlet chamber, a diffusion chamber and a mixing chamber disposed in the casing, and the liquid inlet chamber is composed of a liquid inlet channel and a first injection chamber communicated with the liquid inlet channel. The system is advantaged in that the system is especially suitable for the high altitude environment in Tibet with high altitude, low dissolved oxygen and large temperature difference between day and night.

Description

technical field [0001] The invention belongs to the technical field of fish breeding, and in particular relates to a breeding system for Schizothorax fry on the Tibetan plateau. Background technique [0002] Lhasa Schizothorax is a unique fish of Cyprinidae Schizothorax distributed in the Qinghai-Tibet Plateau region. It is mainly distributed in the middle reaches of the Yarlung Zangbo River System and its tributaries. It is one of the important indigenous economic fish in Tibet. In recent years, with the rapid development of Tibet's economy and society, human beings have been increasingly exploiting and utilizing Tibet's fishery resources. The Yarlung Zangbo River Basin, where the population is concentrated, is undoubtedly also subject to increasingly intense human activities, such as the invasion of exotic fish, the construction of hydropower and water conservancy facilities, overfishing, and water pollution. The impact of these disturbance factors on the ecology of the Y...
