# Analysis and Prospects of an Antarctic Krill Detection Experiment Using Drifting Sonar [PERSON]
## 5 Conclusions  
This study explored the feasibility and effectiveness of drifting sonar buoys for assessing and monitoring Antarctic krill resources through preliminary experiments by deploying a buoy in the Antarctic waters to test their operational functionality at sea. The study indicates that our drifting sonar buoy successfully completed initial tasks, demonstrating unique advantages such as low-cost deployment, conservation of human resources, extensive monitoring coverage, and the capability for continuous and real-time data monitoring. However, the sonar buoy system also presents certain limitations and challenges, such as lower data collection precision compared to large survey vessels and high data transmission costs [38]. Facing these challenges, future research needs to further optimize buoy design to enhance its stability and data collection capabilities in extreme marine environments [48, 49].  
The limitations of the study include a small amount of preliminary experimental data, a single data source, and a lack of more in-depth data analysis. Our team will improve the buoys according to the measures proposed in this paper and use the improved buoys to expand the scale and duration of experiments, further advancing the application of sonar buoys in the assessment of Antarctic krill species.  
In summary, the sonar buoy has the aforementioned series of advantages in detecting krill. Despite some technical and operational challenges, with technological advancements and accumulating experience, sonar buoys are expected to become a vital tool in the assessment and management of Antarctic krill resources, significantly supporting global marine ecological research and resource management.
