The results of these experiments
confirmed that some of the commercially
available cures caused mortality in both
steelhead and chinook juveniles (Figs. 1
and 2). In any given tank mortality
ranged from 0-30% during the 23 day
period. However, researchers also found
that there was considerable variability in
the individual sensitivity of the juvenile
Injection of eggs cured
with sodium sulfite caused 30-35% mortality within a 10 day period. Removal of sodium
sulfite eliminated the mortality (0%).
I know that there are all types of reasons why a laboratory study cannot be directly applied to the river and streams of Alaska. However, the fact a single cured egg with sodium sulfite can kill some juvenile chinook salmon should result in people thinking about using a cure that does not contain sodium sulfite.
