It varies between fish whether or not you want to keep the skin on while cooking. Some just turn to rubber if you try to sear them. Salmon skin comes out a bit like crispy chicken skin. It adds some nice texture and meaty flavor. But everyone’s got their own preferences.

Here in Korea (and I think China too) you can buy seasoned deep fried fish skin in big bags which people use as a snack similar to how people eat potato chips in the west. Sometimes it's also used in cooking to get in some texture and umami.

I die inside when I see people peel off perfectly good fish skin lol. Like dude don’t waste, give that deliciousness to me

As long as it's crispy, it's good!

I was wondering the same... Like why is the skin on top. Then I re-read the title...
