It's possible you will see a white fillet if you order any Wild King Salmon.
White King Salmon looks like regular King Salmon when you catch it. It isn't until you cut it open that you see that the flesh isn't red or pink, but white. White Kings are certainly uncommon and they're highly sought after. They have a slightly softer texture and a bit more of a buttery flavor that's almost sweet.
The "common knowledge" is that the flesh turns white from their diet, however, this seems to have been disproven. Ruth Withler, a researcher at the Canadian Department of Fisheries and Oceans in Nanaimo, British Columbia studies them and says it's actually most likely inherited, even though two red-fleshed Kings can produce a White King. She believes the fish may be missing an enzyme that prevents them from absorbing the carotenoid in their food. Carotenoids are a group of fat-soluble pigments that give plants and animals an orange, pink, or red color, such as tomatoes.
