Description

Technical Field

[0001] The utility model relates to the technical field of agricultural breeding, in particular to an umbrella net device used for breeding Chinese soft-shelled turtle. Background Art

[0002] Chinese soft-shelled turtle, commonly known as soft-shelled turtle, has a delicious taste, is rich in protein, vitamins and trace elements, has high nutritional value and medicinal value, and is quite popular among Chinese consumers. Therefore, the Chinese soft-shelled turtle breeding industry has developed rapidly and has a broad market prospect.

[0003] Greenhouse breeding of Chinese soft-shelled turtles provides a suitable and stable growth environment for them, allowing them to eat normally, and improving their survival rate compared to natural overwintering. At the same time, greenhouse overwintering can make full use of the low temperature period in winter to cultivate large-sized young turtles, shorten the breeding cycle, stagger the peak period for the listing of commercial soft-shelled turtles, meet different market demands, and create conditions for breeding companies to obtain greater economic value. However, greenhouse breeding ponds are smaller in area than traditional earthen ponds, and the breeding density is usually higher. Competition is prone to occur between Chinese soft-shelled turtles, resulting in bites and injuries or deaths. In addition, because young Chinese soft-shelled turtles have poor swimming ability and cannot maintain a swimming posture for a long time, they often shrink to the bottom of the pool or in the corner. Moreover, they are timid by nature and sensitive to external stimuli, which further increases the difficulty of catching Chinese soft-shelled turtles in greenhouse breeding ponds. Utility Model Content

[0004] The utility model aims to provide an umbrella net device for greenhouse culture of Chinese soft-shelled turtles, which can increase the culture space and is easy to catch.

[0005] The utility model is realized through the following technical scheme: an umbrella net device for Chinese soft-shelled turtle greenhouse culture, the umbrella net device is hung upside down above the water surface of the culture pond, the umbrella net device can be opened and closed like a normal umbrella, the edge of the opened umbrella net device is located below the water surface in the culture pond, the edge of the closed umbrella net device is higher than the water surface of the culture pond, and the umbrella surface of the umbrella net device is composed of mesh sheets.

[0006] The working principle of this technical solution is to hang the umbrella net device upside down above the breeding pond, and the umbrella surface of the umbrella net device is a mesh with holes. When the umbrella net device is closed, the Chinese soft-shelled turtle can cling to the umbrella surface of the vertical mesh to hide and rest. This can provide a habitat for the Chinese soft-shelled turtle and also allow the Chinese soft-shelled turtle to hide and prevent individuals from biting each other. At the same time, the three-dimensional breeding space of the Chinese soft-shelled turtle is increased, and the breeding output is improved. When it is necessary to catch the Chinese soft-shelled turtle, the umbrella net device is opened, and feed is fed into the umbrella net device.

Adjacent umbrella net devices will not interfere with each other when they are opened, and the bottom of the umbrella net device is 50cm~60cm away from the bottom of the breeding pond.

[0011] In order to better realize the utility model, further, the umbrella net device is fixed by welding the top of the umbrella handle and the lower part of the cross bar.

[0012] In order to better realize the utility model, further, the distance between adjacent umbrella net devices fixed on the same cross bar is 90nm~110nm.

[0013] In order to better realize the utility model, further, the length of the cross bar along its axial direction is adjustable.

[0014] Compared with the prior art, the utility model has the following advantages and beneficial effects:

[0015] (1) The umbrella net device of the utility model disposed on the water surface can increase the resting space of the Chinese soft-shelled turtle when closed, thereby increasing the unit stocking density of the breeding pond, concentrating the energy supply and avoiding waste; the Chinese soft-shelled turtle can climb onto the umbrella net device to rest, thus avoiding the problem of biting;
