Unlike tilapia, ocean perch is classified by the US Food and Drug Administration (FDA) as the fish most susceptible to mercury contamination because it lives on the seabed (80% of mercury in the upper water layer has been destroyed by sunlight).

Additionally, they are omnivorous, so they are susceptible to toxins and microorganisms living in the water environment. When eating fish with high mercury content such as ocean perch, the toxins will gradually accumulate in the human body. Long-term consumption can lead to mercury poisoning, damage to the oral mucosa, teeth and seriously have effects on the digestive tract and kidneys.
