kd -- strictly diet. Or drugs (hatchery's).
the pink flesh is a result of what the fish is eating crustaceans high in carotene. Fresh water shrimp (scuds), and crawfish are are good sources, as is Mysis Shrimp (Fish Lake). Brook Trout on the Boulder Mountain gorge on a diet of freshwater shrimp - which results in some of the most brilliantly colored flesh you can find.
Farm raised fish that are sent to grocery stores are typically given chemicals that change the color of a fishes flesh -- it is compeltely aesthetic. Pink flesh is much more appealing than white.
The color of a fishes flesh can change very quickly. In only a matter of days, the color can change from white to pink / orange -- all depending on diet.
Hope this helps.
