Unlike other Chinook,
which spend weeks or months in fresh water before spawning, tule fall Chinook
spawn quickly after reaching their home rivers.
Their strategy is to
convert as much of their fat and muscle as possible into eggs or milt. Thus,
they typically appear darker and in worse condition when they arrive at the
spawning ground than other types of Chinook.
Because of the migration
pattern of the adult fish, this stock is a major contributor to the commercial,
tribal, and recreational harvest along the Washington coast and in the Columbia
River.
