Thanks, but my first question is what government organization made this chart? I’d like to see a clearer picture of it.
Are you talking about the mercury chart? It’s from some state DNR - not sure which. Each state is going to be different, and even each lake in a particular state will be different from others. It will give you some idea though of the seriousness, and how different types of fish have different levels of contamination - primarily based on how long they live and what they eat.
