What is the primary food source that feed the Lake Winnebago perch?

The Winnebago system right now has a very good forage base with big populations of "grounders" (trout perch is another name I believe) and also emerald shiners, plus young of the year of white bass, drum etc. Not sure what the perch's primary diet consists of.
