Hey guys/gals. Got a question about fish ranging from trout, bass, crappie, catfish and such in northern utah (happy valley).
How much mercury is in them? I tried to google but mostly came up with warnings from UL.

Thanks for the links.
I thought there would be a list of how much mercury is at each body of water.

The closest you will find to that is the data sheet--last link above. You can get an idea by looking at the Hg levels in the different samples. Some lakes the fish maybe boarderline and in others they might be well over the Hg limit.
Just limit your intake of large browns and bass on those lakes. Usually it is the more piscavorious fish that accumulate the most mercury. Smaller fish along with ones that are more tuned to being insect eaters like rainbows and kokanee don't pick up as much.
Use moderation and you will be okay..

I would bet there's studies and publications, though I don't have references. I know Idaho publishes some public pamphlets on such info.
In a general sense - you can follow the foodchain, being the panfish, smaller varieties, young fish - will have less. As you move up the predator path - the larger fish that eat more other fish will build up more mercury, and other toxins. So big old cats, age old carp, large walleye, fat ass bass - probably have more than say our frisky friendly crappie, gills and perch.
Would also depend on the waters, for sure.
but honestly, I'd still take fresh-caught fish from our agricultural runoff, over farm raised, Chinese import Walmart fishes. For the most part.
Though I'll admit - I do worry about the bundle of Gills I collected at Mantua today. Seems there's been some serious die-off down there. Lots of floating Gills, and seem a number sporting some funky fungus or something - nice big gills half dead, or MORE.
Wonder if someone dropped some Nucular waiste in there!
