And if you can't eat the fish, I'd recommend not drinking the water, either:
The state's annual warnings against eating some fish caught in Indiana's waterways aren't reaching enough Hoosiers, leading some people to unknowingly eat catches tainted with industrial contaminants, public health advocates said Thursday.
One of the first things the neighborhood kids told me when our family moved to Fort Wayne was how much fun it was to go the river and fish for carp. One of the other ones was, "But don't eat them!" (It was during one of those fishing outings that a friend introduced me to the forbidden pleasure of smoking, but that's another story. I should hunt him down and sue him; it can't possibly be my fault.)
