When you live most of your life in icewater, and have the same body temperature as the water and it is also very little food around you, how do you cope...? Learn about the remarkable life of the Arctic charr!
The Arctic Charr lives most of its life in freshwater, but migrate once a year to the sea to get fat. The journey to the sea has to be precisely timed for it to survive. Also, it has to adapt to a very different environment (the sea is approximately 20 times more salty than freshwater). The transition from a freshwater to a saltwater fish, and vice versa, is called anadromy. In this webinar I will tell you about how anadromous fish cope, with focus on the northernmost living freshwater fish, the Arctic charr.
