Chum (dog) are the fourth of five salmon species to migrate from the open ocean up coastal rivers to spawn. Native to the northern Pacific, chum spawn from Oregon up through Alaska and along the northeast coast of Russia. They run with the higher profile coho salmon, but are larger and fight very well. Fresh from the sea fish are preferred because chum deteriorate rapidly once they enter freshwater. They can be provoked into taking dry flies. Most of the time, they hold in the deepest holes of the river. Chum average 10-15 lbs. and you might hook a 30 pounder.
