Effects of episodic exposure to high-pH water on survival of Atlantic salmon eggs and juveniles: Results from laboratory and field Studies
Although effects of acidification on salmonidfish are well studied and documented, effects of episodic high pHhave rarely received attention. In the present study, we investigated effects of high‐pH events on Atlantic salmon (Salmosalar) using bothfield and laboratory data. Effects of an episodic hi...
