Jeez Jeff...... Where the heck have you been catching your Steelhead?
As far as I know, their flesh is maybe orange at best, but white? Do you eat dead floaters?? LMAO.... sorry, couldn't resist..

My best GUESS would be that possibly there is a net-pen operation somewhere raising coho's and one got out. Flesh color is 90% what the fish has eaten through it's life, and Purina fish chow is not conducive to healthy, rich-meated fish.....
