There've been a number of scientific studies done on the issue of mercury in
fish. The most reliable, and longest-running one, the Seychelles study,
confirmed that there are no effects whatsoever, no matter how small, for
people who ate 10 times as much fish/shellfish per week as the average
American. Here's a website re this study, along with another website which
points out quite a few of the inconsistencies behind the mercury claims:-

Whatever the case, even those behind the mercury-claims usually state that
it's OK to eat the smaller fish at the bottom of the food-chain, as they are
claimed to have lower mercury-levels.
In the case of farmed fish, I've found out that the US has fewer rules and
restrictions than European countries . For example, the chemical
canthaxanthin is regularly used in the US to give farmed salmon the same
colour as wild-caught salmon - this is because wild-caught salmon eat
shrimp etc, to get their natural pink-red colour, whereas farmed salmon are
fed all sorts of muck so that their flesh has a sickly grey colour, without
that extra chemical-dye. The UK has banned canthaxanthin, in the case of
organic-farmed fish, because of its suspected cancer-causing properties
etc., but nonorganic farmed salmon can still have the chemical added to it.
I gather that the US doesn't have an official organic category for farmed
fish, as yet, so best to just buy wild-caught fish. Farmed shellfish is
another matter- from what I understand, it's mostly a lot healthier than the
equiavlent farmed fish - there have been some serious health concerns re the
shrimp/prawn-farming industry, but that's all I've heard.
