Introduction

Studies have shown that carnivorous fish such as swordfish are prone to concentrate a pollutant called methylmercury because they are at the end of the food chain. The substance occurs naturally or episodically in the environment. Although methylmercury varies with the environment, it is found in relatively high levels in predatory fish. The central nervous system of young infants and children can show specific toxic responses to this derivative of mercury.

The catfish is commonly known as the pond louse, also known as the wyvern. In addition to its relatively large size, it is also a predator fish with a longer life cycle, and its mercury levels are higher than other fish, making it inadvisable for children.
