Integrated Monitoring System for Shrimp Farming: Combining Acoustic and Water Quality Analysis

The aquaculture industry is a cornerstone of Vietnam’s economy, with the cultivation of white-leg shrimp (Penaeus vannamei) as a significant contributor to its growth. Efficient feeding practices are paramount in optimizing shrimp growth and reducing waste, which accounts for a substantial portion of the production cost. The paper presents an integrated monitoring system that collects acoustic sound of shrimp feeding behavior and water quality characteristics. Acoustic data, recorded manually and streamed to the cloud, provides insights into shrimp feeding patterns, while continuous monitoring of parameters like pH, dissolved oxygen (DO), temperature, and oxidation-reduction potential (ORP) offers a comprehensive view of water conditions. The system was deployed at a commercial shrimp pond at Cam Ranh, Nha Trang to collect data over a shrimp crop cycle. The results reveal that acoustic analysis can accurately detect distinct feeding behaviors, suggesting opportunities for precision feeding strategies. Additionally, water quality parameters, especially DO and temperature, follow consistent daily patterns that correspond to solar activity that can be used to optimally control oxygen aerator. It paves the way for further research into precision feeding using acoustics and understanding the intricate relationship between water quality and shrimp feeding behavior.
