When I first started eating RAF, I ate (raw) salmon skin. I did not want to not eat any part of the animal that I could manage to eat. It wasn't only the nutrition, but coming from vegan for decades, I did not want any part of an animal to possibly be wasted if I could control it. Even though AV (whose diet I basically followed) did not say to eat skin, I ate every drop.
White meat supposedly can be marinated with lemon without harm to digestion. It messes with mine though. Salmon can be considered white meat, as it is not beef, deer, elk, buffalo or bison, but I think it looks reddish colored. Many people marinate fish with lemon. Should be ok. I like oysters, urchin and fish eggs with lemon. I don't let it soak but half a minute though.
