Salmon is an easy-to-fix source of protein that's extremely good for you. One of the many health benefits of salmon is the ample supply of omega-3 fatty acids.

How Long Does Fresh Salmon Last?
If you're lucky enough to have access to whole, fresh salmon, consider purchasing it dressed right off the boat.
Buy your salmon the day before or the same day that you plan to cook it.
You don't want to freeze your salmon prior to cleaning.
While you will want to leave the skin on, the blood and organs should be removed from the inside of the fish. Some find seeing the eyes off-putting; if so, buy steaks, King salmon portions or wild coho salmon fillets.
Wild caught salmon has a strong flavor and odor and over time this can become overpowering, so much so that it can be hard to tell if your salmon has turned rancid. Fresh is best.
