Description

Technical Field

[0001] The utility model relates to the field of graded culture ponds, in particular to a graded culture pond for rare and endangered fish species. Background Art

[0002] Sturgeons are one of the earliest vertebrates in existence and one of the most primitive groups of fish. Take the Chinese sturgeon as an example. It was once an important fish resource in the Yangtze River, but due to habitat destruction and overfishing, the wild population is on the verge of extinction. In order to protect the Chinese sturgeon, China has launched an artificial breeding and farming program, which helps the Chinese sturgeon reproduce through artificially controlled breeding environments and technical means, and has increased its population to a certain extent.

[0003] There are various artificial breeding modes for Chinese sturgeon. During the breeding process, the sturgeons are usually graded regularly according to their growth conditions, and the faster-growing sturgeons are transferred to larger breeding ponds to provide them with more sufficient growth space and feed resources. This can effectively avoid poor growth and quality decline caused by excessive competition.

[0004] In general, the graded breeding management of Chinese sturgeon can help optimize breeding density, control feed intake, prevent disease transmission, etc., which can improve breeding efficiency and promote the healthy growth and output quality of sturgeon.

[0005] The existing technology has the following shortcomings: the traditional Chinese sturgeon grading breeding pond includes multiple non-interconnected grading fish ponds. Professional staff will grade the Chinese sturgeons according to their growth conditions every once in a while, and classify the Chinese sturgeons of different sizes into different grading fish ponds. However, the traditional grading mostly relies on manual grading, which is time-consuming, labor-intensive and inefficient. Some grading breeding ponds also have a grading method using grading screens with different gaps, but the Chinese sturgeons will always touch or be squeezed by the screens during the grading screens, resulting in the Chinese sturgeons not actively passing through the screens, resulting in the grading method relying on the grading screens being too slow and inefficient.

[0006] Therefore, it is necessary to invent a rare and endangered fish species graded breeding pond. Utility Model Content
