I don't know how I ended up on this post from 2000 miles away, but we have gone over this same hook issue many times in our area. The way it has been broken down is that any device intended to catch one fish is one hook, so a jigging rap with a nose hook a tail hook and a treble hanging off the belly is considered one hook, while something like a Sabiki rig, although all on one line, is intended to catch multiple fish so is considered multiple hooks. And I'm not really into perch, or jigging for that matter, but when I get the urge I toss a Sweedish pimple down the hole and it's pretty much foolproof.
