I didn't look at Andy's links but feed trained perch are definitely available in Wisconsin. Most likely they were first feed trained in Wisconsin! The yellow perch I feed trained myself are voracious feeders at feeding time.
As far as eating fish i didn't like eating them much as a kid growing up but I sure liked catching them. In retrospect my mother really didn't now how to cook them although she is an excellent cook otherwise. Once I took it upon myself to learn different ways to prepare them and now I absolutely love eating fish!
