Methyl mercury concentrations in walleye (𝑛=221,960) from lakes for which GLIFWC issues consumption advice (see DeWeese et al. 2009 [9] for a description of lake codes and advice categories).

All: walleye harvested from all lakes for which GLIFWC issues consumption advice.
Red: walleye harvested from lakes color-coded red (those for which GLIFWC issues do-not-eat advice)
OR: walleye harvested from lakes color-coded other than red (lakes with consumption advice less restrictive than do-not-eat).
