Catfish
Did you know that large catfish are raised and fed with hormones to increase their weight for the purpose of high profits. These fish are considered unclean and at risk of containing toxic mercury, so readers should consider choosing them carefully.
Ocean perch
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).
In addition, 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 cause mercury poisoning, damage to the oral mucosa, teeth and seriously affect the digestive tract and kidneys.
