British Expats - Haha - the Australian response to the shark 'problem' ...

Quote:

Didn't know about the mercury levels in shark, had heard about this in salmon and assumed (probably wrongly) that this was due to the salmon being farmed and so were swimming in more polluted water.

As we are always told to eat more fish, what fish is good to eat which doesn't have high mercury levels? Surely if the mercury levels in the sea/ocean were increased as a whole then all fish/sharks would be affected?

The higher up the food chain that a fish is the more mercury it will contain, fish like tuna and shark are up there at the top end of the food chain.
