It doesn't end up on dinner plates and it lacks the popular appeal of whales and dolphins, but scientists warn that a small fish that is critical to Arctic marine life could be in trouble from climate change and human activity.
Maxime Geoffroy, a researcher at the Fisheries and Marine Institute of Memorial University of Newfoundland, said the fate of the Arctic cod — also known as the polar cod — has a ripple effect on animals such as beluga and bowhead whales and ringed seals.
Geoffroy and a consortium of dozens of international scientists sounded the alarm on the fate of the fish in a scientific review published this month in the journal Elementa. There are a few other larger species of fish found close to the Arctic floor, but they are not as plentiful, and most of them also feed on the Arctic cod, Geoffroy added.
Most of the planet is covered by oceans, which have absorbed 90 per cent of the recent warming caused by planet-warming gases such as carbon dioxide and methane. Global sea surface temperatures have been at record highs since April, meteorologists report as climate change is linked to more extreme and deadly events.
