My go too spot for early Perch is Hacketts. I use depth finder to search around but 9 times out of 10 - find a few due west of can about 50 feet. Should be 22-24 feet of water.
Fresh bloodworms without a doubt is best bait until waters warm up.
Most years I try there when Blue Angels fly and get a few. The air show is next Weds (20th ) - I'll guess a few Perch will be there.
# 4 spinner hooks help attrach them.
