Or you could do some light research to find out which kinds of fish have highest and lowest mercury levels?

My understanding is that the more you go in the apex predator direction, the more you'll find mercury and other undesirable shizzle.

Generally, the bigger the fish, the more fish it has had to eat, and the higher murcury concentration.

That's what I'm saying, yes.

Similar reason why orcas are functionally toxic to eat. IIRC their livers and fatty tissue are dangerous because of pollution traveling up the chain.
