Description

Technical Field

[0001] The utility model relates to the technical field of breeding devices, in particular to a Chinese mitten crab breeding device for a laboratory. Background Art

[0002] The Chinese mitten crab (Eriocheir sinensis) is an important freshwater economic aquaculture species widely distributed in China and surrounding waters. Its delicious meat and high nutritional value make it a popular aquaculture target. Laboratory aquaculture devices can provide an ideal platform for research in fields such as biology, ecology, and aquaculture. Researchers can observe and record the growth, reproduction, behavior, and response of Chinese mitten crabs to different environmental conditions in a controlled environment. However, existing devices cannot control the amount of bait released. Too little bait leads to insufficient nutrition, while too much bait will cause the crabs to rot, affecting the growth environment. For example, China has disclosed a "crab aquaculture device" with the application number "CN201720600143.5". This device uses multiple feeding discs to release bait along the slope of a simulated embankment, adapting to the crab's living habits. The device also automatically feeds the crabs, evenly, and efficiently. However, the device cannot adjust the amount of bait released, thus failing to prevent slow growth or stunted development caused by insufficient bait. Excessive bait will cause rot within the aquaculture box. It cannot prevent the Chinese mitten crabs from escaping the aquaculture box, and is difficult to remove and inspect. Utility Model Content
