In spite of below freezing temperatures, Canada’s Arctic waters provide breeding grounds for 119 different species of fish from Greenland sharks to Arctic char. Fish have adapted to the frigid waters in a few different ways - some change their body chemistry, while others generate their own “antifreeze” or live deep in the ocean. Fish are an important part of the Arctic food web providing food for sharks, seabirds and marine mammals like seals and walruses.
Overfishing is a problem in most of the world’s oceans. Until recently Arctic waters were difficult to access, but with melting sea ice industrial fishing in the Arctic is becoming more accessible. And fish aren’t the only species affected by overfishing. The many species that depend on fish for food also suffer if fish stocks decline.
