Good fish smells clean and fresh, perhaps a little briny, like the ocean. Fishy odor is the first sign the fish isn’t fresh. The eyes should be bright, shiny and full; cloudy (or milky) sunken eyes are dead giveaways the fish has been sitting around too long, Reuters reported. The fresher the fish, the brighter and more metallic the skin; the skin should not be dull, even in patches. The fish should be nice and firm, springing back from any touch (it should not be soft or squishy). Also the gills should be clean and a bright red. As a fish ages, its gills dull and start to turn brown.
