Re: Eat your catch or release?
Here's what WI says:
Health Advisory for Eating Fish
Although fish are delicious and nutritious, some fish contain contaminants at levels
that can pose health risks to people who eat fish frequently. To reduce your exposure
to these contaminants, the state issues advice to help you plan what fish to keep as well
as how often and how much fish to eat. Please read the information below and consult
the complete fish consumption advisory as a guide to eating fish low in contaminants.
Fish consumption advice is provided for fish that may contain mercury, polychlorinated
biphenyls (PCBs), and other compounds.
Statewide mercury advisory: Mercury is found in almost all waters throughout the state.
Wisconsin?s statewide advice for most of Wisconsin?s inland (non-Great Lakes) waters
recommends that:
Women of childbearing years, nursing mothers and all children under 15 may eat:
? One meal per week of bluegill, sunfish, crappies, yellow perch, bullheads, inland
trout; and
? One meal per month of walleye, northern pike, bass, catfish, and all other species
(The exception is muskies, which should not be eaten by this group of people
because of the high mercury content in muskies).
Men, and women beyond their childbearing years may eat:
? Unrestricted amounts of bluegill, sunfish, crappies, yellow perch, bullheads, inland
trout; and
? One meal per week of walleye, northern pike, bass, catfish, and all other species.
?
One meal per month of musky. 
Release! Unless it's a wallhanger...

Studies suggest that regularly including modest amounts of fish and shellfish (1 or 2 servings
per week) in you diet can benefit your health. Little additional benefit is obtained
from consuming more than that amount. And, for some waters, fewer meals should be
eaten. On certain waters, where data indicates higher mercury levels, more restrictive
advice is needed. In addition, fish purchased from stores or restaurants may contain
mercury. Consult the fish consumption advisory booklet for more specific advice.
