New technology is allowing researchers to covertly monitor, record and identify the sounds fish make underwater to try to unravel their deepest secrets. 

Researcher Xavier Mouy, a recent PhD graduate at the University of Victoria, and his colleagues have devised a relatively low-cost portable audio-visual system that surreptitiously records the surprising range of acoustics fish produce, but more importantly, pinpoints what creature makes which sound.

Thriving in cool water temperatures, kelp forests cover over a quarter of the world’s coastlines, with Canada having the longest, says Marissa Ng, Seaforestation Project Coordinator for Ocean Wise.

“In the Pacific Northwest, kelp forests are a foundation species. Similar to salmon, they’re important for the health of the coastal ecosystem,” said Ng. “They’re also foundation species because they’re so abundant up and down the coast and much like forests on land, marine forests – kelp forest – they provide food and shelter for thousands of marine species.”
