Fish can be an excellent source of protein and omega-3 fatty acids. Unfortunately some fish can contain high levels of mercury. This occurs through bioaccumulation. The Monterey Aquarium has developed a series of resources to help consumers learn about which fish are safe to eat as well as which to avoid.
