Fish finders are wildly used in fishery, fish stock assessment, and fish behavior research. Satellite fishfinding buoy can be used to assess fishery resource in a particular area with a long-term unattended work. We designed a drifting buoy for krill swarm detection, and released at west of South Orkney Islands, Subarea 48.2. The buoy worked normally for 7 days 2 hours and sent back 157 sets of valid data before offline. It was the first fish-finding drifting buoy for Antarctic Krill, and the data it sent back is valuable for us to improve our further design.
