BISC Postdoctoral Fellow Kieran Cox featured on CBC Radio's North by Northwest

March 16, 2022

CBC Radio's Sheryl Mackay, host of North by Northwest, interviewed Liber Ero and NSERC Postdoctoral Fellow Kieran Cox (Côté lab) last Saturday March 12, about his fish sounds research.

Dr. Cox is a part of an international collaboration applying a cross-disciplinary approach to consolidating acoustic recordings and published information on sound production across all extant fish species globally. Combining expertise in fish ecology, bioacoustics, and data management, the team recently released, a comprehensive global inventory of fish sound production that allows users to search based on fish taxa, by sound characteristics, or by reference.

To create, the team extracted data from more than 800 different studies to determine that 989 fish species have been shown to produce active sounds globally. In addition to forming the foundation of the FishSounds database, this survey was recently published in Reviews in Fish Biology and Fisheries. See 'A quantitative inventory of global soniferous fish diversity' for more information on the taxonomic and geographic distribution of soniferous fishes.

The FishSounds Team, which includes the University of Florida PhD Candidate Audrey Looby, MERIDIAN members Sarah Vela and Amalis Riera, and Dr. Francis Juanes, are now developing a data upload system for the website, an interactive taxonomic tree, and user profiles.
