Yellow Perch is a freshwater fish about the size of a trout, though a little heavier bodied. Take your trout rod. I don't think their would any need to exceed say a 4-10 lb line rating on your rod and it may be beneficial if you are bank fishing to use the longest you have.

Do you mean sea perch? jetty or surf fishing?

I think he does? If so the rod of choice has been the X106mhc for a bait caster or a X10mts for spinning.
