Real-time acoustic fish telemetry

Real-time acoustic telemetry for fish behaviour monitoring in aquaculture.
I have been working with two major projects in my PhD.
- Fish speed measurement based on Doppler shift in acoustic signal. Verification of the proposed method for 1D and 2D speeds have been successfully carried out in lab, fjord (open-sea) and also inside a fully-stocked fish cage. As a final step, further experiments with tagged fish inside a fish cage are also planned.
- Internet of Fish (IoF), a concept based on the Internet of Things (IoT). IoF uses LoRa LPWAN and provides real-time support to fish telemetry data. The IoF system has successfully tested for real-time telemetry data collection and fish positioning at various aquaculture farms.

Status and further work:
- Validation of the Doppler shift based speed measurement principle with tagged fish inside a fish cage.
- A manuscript presenting the proposed Doppler based swimming speed measurement technique is under review.
