I think the North Atlantic Salmon and people who like sport fishing can be thankful to Orri Vigfusson who founded The North Atlantic Salmon fund. A quote from their website: "The North Atlantic Salmon Fund, NASF, is a coalition of voluntary conservation groups who have come together to restore stocks of wild Atlantic salmon to their historic abundance."

Before NASF some rivers in Iceland, Ireland and Scotland were virtually fenced be fishing nets so that only a small fraction of the salmon stock managed to spawn in the rivers. NASF has managed to help turn things around and the salmon rivers are recovering nicely.

Imagine how it was before, you got your fishing license in a good river but almost all the fish was caucht in nets before reaching the river! I am thankful that this belongs to the past and catching salmon in the sea is banned around Iceland. Maybe it is banned also in the whole of the North Atlantic Ocean?
