Index of cumulative mortality in juvenile Chinook and steelhead parr and smolts.

<p>Juvenile Chinook and steelhead parr and smolts were fed cured eggs for a period of 23 d. We calculated cumulative mortality by summing the number of fish that died each day for all treatment groups (calculated separately for each lifestage and species) fed cured eggs and dividing this by the total number of fish that died during the 23 d period.
