That is an interesting take on the "mercury problem". They probably don't show "fresh water" fish, because they aren't so much a "commercial" product, as they are a local/regional product. Most fish consumed, by the majority of the worlds population, are probably "cold water" fish or "saltwater" fish.Originally Posted by skiptomylu
The EPA says fish that contain less than 0.3ppm of methylmercury are "probably" safe for most people. Here's a PDF listing the ppm sampling of some of the freshwater fish consumed by the public.

It shows Crappie as being well within the statistically "safe" limits.
HOWEVER ....... not all advisories, on fish consumption, are related to mercury alone. PCB's & Chlordane are the culprits, in most cases, in the states of KY & TN. They may also be the determining factor in other states. I just happen to have a "Fishing Regs" pamphlet from these two states, since they are the two states I most often fish in. And there are also certain bodies of water, or portions of those waters, that have higher levels of contamination than others, or the remaining portion of those same waters ... usually due to spills, runoffs, or close proximity to a pollution source.
Fish Consumption Advisories are voluntary warnings ... and are probably set to reflect the "worst case scenario". They are set to err on the side of caution. .............. cp
