Abstract:Proposed development of a mine within Alaska's Bristol Bay watershed has raised concerns about the potential impact of copper (Cu) on Pacific salmon (Oncorhynchus spp.). We conducted 96‐hour flow‐through bioassays using low‐hardness and low‐dissolved organic carbon water to determine the acute lethal toxicity of Cu to sockeye (O. nerka), Chinook (O. tshawytscha), and coho salmon (O. kisutch) fry. We aimed to determine Cu toxicity under field‐relevant water quality conditions and to assess three methods of calc… Show more
