chinook is native to the Pacific Coast from California
to Alaska and British Columbia, Canada. It is
also found in the Great Lakes and their tributaries.
Chinook generally live a four-year life cycle,
though salmon up to seven years have been recorded.
Longevity helps them attain such big sizes, but
chinook also get an earlier start than other salmon.
While coho seldom hit the big water until they're
almost 18 months, chinook head for the ocean or
lakes within days of hatching. Chinook wander
about the big water in loose packs. They're more
light sensitive than many other salmon and often
hold in deeper water.
