other species?
what about? flathead,bream,whiting,snapper? these fish are found in Australian waters and are common to catch and are favourites to eat.I am curious to know the levels of mercury contained in these fish as I often eat these varieties.I can then compare them to salmon,flounder,shellfish.Also what about prawn's?
Katherine Hobson: Check the links in the story for the EDF and Monterey Bay Aquarium guides, though they may not be locally appropriate if you're in Australia. Here's an Australian-centered guide:

I don't think that has mercury info, but check the EDF guide and see if that helps.
Concern over mercury in marine fish is overblown
It seems these days that one can't read about the benefits of omega-3s from marine fish without coming across warnings about mercury. Mercury is toxic. The fact is well established. What is curious though, is the lack of reference to selenium in these very same fish.
The fish group that elicits most health warnings over mercury content, the tunas, have greater concentrations of selenium than mercury. Selenium is used to treat cases of mercury intoxication. The tuna with the highest ratio of Se/Hg is...Yellowfin tuna. So, if consumers are concerned about expisre to mercury, they should eat more tuna not less.
The research on this subject is abundant and well established. It seems most reporting is based on older information gear more towards sensationalism than informing the public.
