Description

Technical Field

[0001] The utility model relates to the technical field of temporary breeding cages for butter crabs in ponds, in particular to a multifunctional breeding cage for temporarily breeding butter crabs in ponds. Background Art

[0002] The butter crab, a key aquaculture species in my country's coastal regions, exhibits a unique growth state. Its body is rich in golden fat, which permeates its muscles. Its hemolymph is yellow (compared to the blue hemolymph of the standard mud crab), and the joints of its legs are transparent and yellow. It is commonly found in the waters of Lau Fau Shan in Hong Kong and the Pearl River Basin. Its unique taste and flavor, as well as its excellent nutritional value, have earned it a widespread consumer appeal. A premium food sourced in the Guangdong-Hong Kong-Macao Greater Bay Area, it is known as the "King of Crabs," fetching prices exceeding thousands of yuan per 500 grams, demonstrating a promising market.

[0003] The valuable butter crab species boasts enormous economic benefits, with an estimated annual output value of 1 billion yuan, attracting the attention of farmers and aquaculture companies. However, the occurrence of butter crabs in natural populations is extremely rare, with only one butter crab produced among thousands of farmed blue crabs. After catching butter crabs, butter crab farmers typically place them in land-based cement ponds and crab apartments for temporary rearing before selling them. However, due to changes in the aquaculture environment, butter crabs survive shorter periods in these ponds and crab apartments and are prone to "oil loss." Consequently, cages for crab farming have become popular with butter crab farmers and companies.

[0004] In the existing technology, the cages used for crab farming do not have underwater feeding and monitoring functions. Feeding bait requires lifting the crab cage suspended in the water before feeding. This process can easily cause stress to the butter crabs and lead to "oil loss", which greatly reduces the quality and price of the butter crabs. Utility Model Content

[0005] The utility model aims to provide a multifunctional breeding cage for temporarily breeding butter crabs in ponds, which can solve the problem that butter crabs are easily stressed when temporarily bred after being caught.

[0006] The purpose of this utility model is achieved through the following technical solutions:

[0007] A multifunctional breeding cage for temporarily rearing butter crabs in ponds comprises a cage, a feeding pipe mounted on the cage, and a monitoring device. The lower ends of the feeding pipe and the monitoring device both extend into the cage. Bait is manually fed into the cage through the feeding pipe, and the crabs' feeding status is monitored using the monitoring device.
