Perch, like other panfish can be a real blast to ice fish for - and is some of the mildest flavored fish that nature has to offer when from ice cold water. The flesh is white and flaky, and perch taken from ice cold water doesn't have the muddy flavor it often does in the summer months- what a bonus!  Perch are a cousin of the much larger walleye, and are similarly a schooling fish - and if you get into an active school of feeding perch - can be explosive and frantic action!

As you can see in this pic - a mighty nice 'jumbo' perch!

WHERE'S THE PERCH?
As with any fish - in any frozen water - a trip to the local bait/tackle shop is a great source of info before hitting the ice. Ice fishers share their catch info much of the time and the info you can find out at the bait/tackle shop will be in-valuable and save you much time and effort!
Generally though, perch will be in water anywhere from fifty feet deep to three feet deep, with my favored depth being  twenty five feet. Perch do, but rarely suspend as do walleye and crappie, and most often the old 'go to the bottom, and up a foot' rule of thumb of ice fishing applies here, for sure! Perch, like most fish like to be around structure, but in larger lakes the structure may well be the water column itself. In smaller water perch are more solitary and may not school appreciably, as they do in mid sized and large water bodies. In water that host beaver houses - fish out off the beaver house ( being very careful of thin ice) in water deeper than ten feet deep and you should locate actively feeding perch.
This article is a great overview and with info here you should be able to catch perch - but if you enjoy this - you will need more info to be able to be consistent at catching perch - the info you need is in myICE FISHING BASICS book, and I urge you to take a look and purchase it - it'll save you time and money and will easily pay for itself on the first couple of ice fishing trips you make!

ICE JIGS & BAIT!
There are thousands of ice jigs suitable for perch, and most will catch fish. My own personal preference are several that I've taken years to develop using my experience and knowledge and education - the science is behind me - not just 'a few more' ice jigs! These are 'glow black' Ice Tick Jigs, Sunfish Jigs and Teeter Totter Jigs. But make no mistake, the standard Tear Drop ice jigs, Genz Worms, Russian Hooks ...just to name a few - all work well too! After my 'glow black' coloration I prefer chartreuse, hot pink, florescent red and orange, florescent yellow for perch, and if the water is stained or stained badly, I use the chartreuse most of the time after my glow black concept. Contact the web master looking after this page forinformation on ordering Ice Tick Jigs, Teeter Totters and Sunfish Jigs!

Whatever jig ( info on using jigs) you use it should be sufficient heavy to quickly get you back down to the depth you are catching fish - you must keep the fish's interest up or they'll leave. Having said that, I like jigs of about a size eight to ten ( hook size) for perch, using the smaller jigs if they are neutral or negative. I will use add-on weight if the jig isn't dropping back into the 'kill zone' quickly enough, and like my weight beads for this, but round removable split shot is fine - just be sure not to pinch the line when applying it. If you are into a lot of big perch - don't be afraid to go to a size six hook - for ease of removing the hook with cold fingers!
For bait - a live minnow is hard to beat - but wax worms, maggots and mousy are also excellent - without all the mess of the water and big bucket associated with minnows! You'll have to check with your DNR to see if live bait can be used in your area. If using small maggots I'll use several of them bunched up on the hook, and only use a perch eye which is also a good and tough bait - when the bite is on. Perch eyes as an attractor are only mediocre - and I'll most often use one of these other baits and switch to a perch eye when the fish move in and the bite is on!

IMPORTANT THINGS - just do it!
Finding perch can be grueling work - I'll often drill up to fifty or more holes to find 'em as perch move around a lot in search of food - you will have to as well. Of course the smaller the water you're fishing - the easier they are to find, but most often the best quality and size perch seem to consistently come from mid sized and large water bodies. Smaller water bodies will see perch more territorial than schooling.
Keep that bait in the water - a foot above the bottom - and jig very lightly - perch don't want too much jigging action most of the time. I like to gently jig, then allow my bait to sit motionless for  while before starting to jig again. Again - KEEP THAT BAIT in the water - once a school of perch is working your bait/area YOU MUST hold their interest or they'll move on - and fishing'll go dead!
The basic info here will enable you to catch perch - if you are really 'into' ice fishing and need more information to be the best you can be at it - I'd urge you to consider buying my book Ice Fishing Basics where you'll find much more information and explanations of why we do what we do.
For a LOT more info on Ice Fishing technique, see blue side bar for ice fishing JIGs - much "How To" info is found there! For not available anywhere else perch jigs - see product section - these are what I use as a 'pro' 
For now though, BEST OF LUCK!
