Real-time acoustic telemetry for fish behaviour monitoring in aquaculture.

I have been working with two major projects in my PhD.

  1. 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.
  2. 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.
