Last August I caught and ate a red spring from the ocean (up near Port Hardy) that was a female. It was obviously chrome, and the eggs were not fully mature. The flesh was bright orange in color, but the taste was bland - it just wasn't a very fatty fish. Then in September I caught and kept a male white spring from the Vedder (Chilliwack actually) near the upper boundary. It was a very early fish (mid-September) but it was gold tinged on the outside and had lost many scales. My wife and I (and our friend who was also there for the red spring) all agreed that it was one of the best tasting chinook we have ever had. I kept two more gold colored males in September and they both had marble flesh and were delicious - I used most of them for sashimi because it was that good. I kept a white female spring in early October and it was so-so quality, even though she wasn't more colored than the males I had kept.
Of coho last year, although I generally agree that more scales is better quality, I found the divide between the sexes to be just as stark. Males, even when slightly pink on the outside, were better than the chrome female coho. Of course, as it is my wife and I fight over the eggs (her for caviar, me for bait) so if I didn't keep any females neither one of us would be happy!
The chrome pinks I have seen kept on the Vedder generally have faded flesh even if they have sea lice, so I haven't even bothered to keep one for the smoker.
