Understanding whether fish communicate using sound is of growing interest and importance. Although many fish species are soniferous⎯they naturally produce sounds⎯we know very little about how and why this happens. Among the approximately 400 known marine fish species swimming in British Columbia waters, only 22 have been reported to be soniferous, although many more species are suspected to produce sound.

Ocean Networks Canada (ONC) is partnering with University of Victoria and the Institute of Marine Sciences in Barcelona, Spain, to deploy an innovative experiment to study fish behaviour through sound and imaging. Combining video and passive acoustics (i.e., hydrophones) with acoustic imaging, the experiment aims to better understand fish behaviours through fish-emitting...
