Minor changes to four chum salmon data sets:
-
Kotzebue chum salmon ages were corrected to be ages 3-7, not ages 2-6. This
change does not impact the total recruitment values. -
For Fraser River chum salmon, the 1966 brood year was flagged as don't use
because of a suspect spawner value. -
Age structure for Prince Williamson Sound chum salmon was changed from a mix
of data and average age proportions to assuming all returns were age-4. The
age-proportions previously used are suspect and alternative values were not
available. -
Age structure for Upper Cook Inlet chum salmon was changed from a mix of data
and average age proportions to assuming all returns were age-4. The
age-proportions previously used are suspect and alternative values were not
available.
