Species Profile

Blue Whiting

Also known as Poutassou, Couch's Whiting

Blue whiting form massive, dense schools in the mesopelagic zone, migrating vertically each day to feed on zooplankton under the cover of darkness. Their slender, streamlined bodies feature a distinct bluish-grey back that fades into a brilliant silvery belly, helping them blend into the open ocean depths. As a vital link in the marine food web, they support vast populations of larger predatory fish, marine mammals, and seabirds.
