Study: Salmon farms have fewer essential nutrients needed by humans than other fish species. Oily fish such as mackerel and anchovies contain essential nutrients including calcium, vitamin B12 and omega-3, but some are lost from our diet when we eat salmon fillets.

Eating more wild fish species such as Mackerel, anchovies, and herring directly could benefit our health, while reducing the demand for farming fish species (such as salmon) that feed ON MARINE SPECIES.
