![]() ![]() “We realized we had to go deeper to know which fish is present, and potentially in the future, how many.” ![]() “If you tell people that you use acoustics as a new way to detect fish in the ocean, that's not exactly groundbreaking,” Mouy told Canada's National Observer. ![]() But there are huge gaps in scientific understanding around the vocal repertoire of individual fish, he said. It's no secret that fish as a whole make a bunch of different noises, like hums, clicks, grunts and even farts for breeding, feeding and protecting territory. 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.īeing able to do so is akin to identifying who is attending a noisy party in a dark room, said Mouy, with important outcomes for scientific monitoring, fisheries and conservation in marine environments. New technology is allowing researchers to covertly monitor, record and identify the sounds fish make underwater to try to unravel their deepest secrets. ![]()
