Yes years ago my dad showed me perch eyes worked.Its kind of messy if you dont remove eyes correctly and it stays on the hook for a long time caught lots of perch that way.Also used cut bait bellys from fish cut about 2 inches long by half inch wide.It stays on hook long time doesn't get mushy.Also try dropping a can of cat food down on a small rope or string use can opener and put some holes in can drop to bottom of lake and some food comes out and attracts fish.Yep now that I am a old time may as well pass it down.Good luck.
