Water quality limits for Atlantic salmon ( Salmo salar L.) exposed to short term reductions in pH and increased aluminum simulating episodes
International audience Acidification has caused the loss or reduction of numerous Atlantic salmon ( Salmo salar L.) populations on both sides of the North Atlantic. Acid deposition peaked in the 1980's and resulted in both chronically and episodically acidified rivers. At present, water quality...

International audience Acidification has caused the loss or reduction of numerous Atlantic salmon ( Salmo salar L.) populations on both sides of the North Atlantic.
