Eric,
Try it. I have eaten skin-on canned fish for many years. No brillo pad, just soft, good eats.

St Jeans cannery in Nanimo makes, IMHO the very best smoked canned slamon around and yes it does have the skin on. Many friends have tried it, as it's my go to fishing day lunch. All have agreed its great.

As the saying goes, don't knock it if ya havn't tried it.
