Description

Technical Field

[0001] This application relates to the field of aquaculture technology, and in particular to an oxygenation device for crab ponds. Background Technology

[0002] In the crab farming industry, aeration devices are crucial for ensuring the crabs' living environment and maximizing farming efficiency. However, most traditional aeration devices have a fixed structure, making it difficult to flexibly adjust them according to the size of the crab pond and actual oxygenation needs. Crab ponds vary significantly in size from small backyard ponds to large commercial aquaculture ponds. Fixed-structure aeration devices cannot effectively cover the appropriate area. In smaller ponds, this can lead to energy waste and over-oxygenation, while in larger ponds, it fails to meet overall oxygenation requirements, resulting in insufficient oxygen levels in some areas. This negatively impacts the crabs' growth, development, and health, ultimately reducing the economic benefits and yield stability of the farming industry.
