What would cause a raw fish fillet to turn yellow around the edges?

Rating: 77

When a raw fish fillet turns yellow around the edges, it is probably an indication that the fish is getting old. As a fish is stored, it loses acidity and the normally white flavone pigment turns yellow in the process. Oxidation also causes pigments to change color.
