I think stripers will eat anything they can get in their mouth. I've had catfish guys tell me they catch them on cut bait and find them full of small catfish. I've watched guys fish at the PK dam catch them on cut perch. I've caught them on live perch as well.
The main reason you find those stripers near the bottom is water temp. They want 55 deg water. Unlike trout, they don't die in warmer water but don't like it one bit.
John 21:3 Simon Peter saith unto them, I go a fishing. They say unto him, We also go with thee.
