I was with ya until you mentioned the eating habbits of the chum salmon. My understanding is that they are mainly plankton eaters, with a few crustaceans and squid thrown in. I think their diet is very similar to pink salmon and sockeye. Kings and cohos feed mostly on bait fish.

Most of the small wild trout I've caught and ate from small streams have had white meat. Same with those fish in the alpine lakes.

When I lived on a small sw washinton river, I used to catch and eat lots of trout that had only white meat. Then when the bigger sea run cutts came in, they would tend to have pink meat.

Jim - here is some info I found about white chinook: "White chinook essentially the same as the more common red chinook. The primary difference being that the whites have a genetic code that does not produce the red pigment found in most salmon". I've also heard the meat is more oily, deteriorates fast, and not as good eating.
