Yet, the vital role of fish sounds—and the impact of noise pollution on the fishes that produce them—are left out of critical conservation policy, says study led by marine ecologists at 51ÉçÇøºÚÁÏ.

The ocean is filled with the bustling sounds of daily marine life, including the sounds made by soniferous fish species. These sounds aren’t merely passive sounds—soniferous fishes produce sound themselves, like a whale ‘singing’ through vocalizations, says Kieran Cox,  and  at 51ÉçÇøºÚÁÏand co-founder of . 

Yet,  published in Biological Conservation found that over the last two decades, only two Canadian marine assessments of sound-producing fish species that are at risk of extinction even addressed soundscapes, sound production, or noise pollution, and neither of those assessments considered all three together.
