Some people claim that salmon has a taste that is very similar to that of tuna when it is cooked while others think it tastes less fishy. The fact of the matter is that salmon has a fairly unique taste of its own. Salmon tends to melt like butter when cooked and goes great in a variety of dishes, making it very versatile in the culinary world.
Those who find that their salmon has a strong fishy smell or taste will want to make sure that it has not gone bad, simply because it could be a sign of a bacterial infection which could potentially lead to food poisoning. There are also certain parasites which can live in the blood of salmon and it is important to cook it all the way through in order to avoid exposure to them.
