>>18801Do some testing, shrimp may work ok. At least here in southern finland many perch tend to have different species of shrimp in their stomach.
Corn is another you may take look at, it's good for cyprinids (roach, bream ect.). And if you don't feel bad for killing the fish for bait you can use bits of roach to fish perch.
