Canned salmon is already cooked - just drain the liquid and it's ready to eat or add to your favourite dish. You can remove the skin if you like. Don't throw out the soft, calcium-rich bones!

The USDA cautions: “do not rinse raw fish, seafood, meat, and poultry. Bacteria in these raw juices can splash and spread to other foods and surfaces. Cooking foods thoroughly will kill harmful bacteria.”
Is canned fish ready to eat?
Most canned fish is cooked before being preserved in metal, so they're safe to eat straight out of the can. However, make sure that you haven't accidentally purchased a fish that requires cooking beforehand.
