British Columbia Researchers Identify Fish Species Sounds

University of Victoria researchers reported Jan. 9, 2025 that they used underwater microphones near Bamfield in Barkley Sound to record and classify unique sounds from eight fish species. They trained a machine-learning model to distinguish species-specific knocks, grunts and croaks—including five rockfish species, lingcod, kelp greenling and pile perch—enabling potential non-invasive monitoring for conservation and fisheries management.
Key Points
- 1Identified sounds: Detected and classified unique acoustic signatures from eight coastal B.C. fish species
- 2Demonstrated ML accuracy: Machine-learning model differentiated closely related species using length and frequency features
- 3Enable monitoring: Acoustic detection offers non-invasive species presence monitoring for conservation and fisheries management
Scoring Rationale
Solid peer-reviewed ML application with practical conservation utility, but limited geographic scope and incremental novelty.
