Coherent high-speed acoustic communication inside a commercial atlantic salmon pen
Fish telemetry is a potential method to monitor the well-being of farmed fish, where a reference group of fish are equipped with sensors tags that oversee their health and wirelessly transmit the data. Many fish must be tagged to get statistically reliable information. In this paper, very-high-frequ...
