Water chemistry linked to failure of sockeye hatchery in Idaho


Interesting article about high mortality in a hatchery built to preserve the endangered run of Snake River sockeye.  It sounds like a mismatch in water chemistry was the main cause of the high mortality.  I’m somewhat surprised that juvenile salmon would be that sensitive to what seems like small variations in water chemistry.  Likely another example of local adaptation to a variable that we don’t often consider.
