Like beagle dog said "Tule the other white meat" they do enter the river ready to spawn, but they are a geneticaly different sub-species of chinook salmon native to the lower columbia river tribs. When they are out in the ocean they lack an enzyme required to digest the exoskeleton of shirmp which is responisible for the pink coloring we like to see in our anadromous fish. I have caught them at illwaco and they are chrome outside, white inside.
They do stink, but get a big hen and you are just about set for springers. I like how everybody gives them to there neighbor. Me and beagledog are going to start calling them neighbor fish instead of tule.
