Research by Australian medical experts shows that parents should be wary of giving their children seven kinds of fish: shark, swordfish, swordfish, marlin, tilapia, square head fish and catfish. Because these fish are relatively large, they are carnivorous fish with a long life cycle, and their mercury content is higher than other fish. If children eat this fish for a long time, the mercury content in their bodies is likely to exceed the standard, and even a relatively low mercury content will affect the normal development of children.
