Did Ja Know?

Burbot "Sing!"

Graphic: Burbot

Peter Cott, biologist with the Northwest Territories Department of Environment and Natural Resources, and his colleagues published an intriguing note in the June 2014 issue of the Journal of Great Lakes Research called the "Song of the Burbot." The team found that burbot make noise beneath the ice during their spawning season. The noise isnít so much a "song" as it is "drumming," akin to that of a distant ruffed grouse or revving motorcycle. Burbot are a type of cod, and like Atlantic cod and haddock, they produce sound via quickly contracting muscles attached to their swim bladder as part of their spawning ritual. To hear the sound and learn more about burbot, listen to the 8-minute audio show "Burbot and the Lota lota Love Song," available online at: www.seagrant.umn.edu/radio/sgf
