When considering location, the yellow perch is a fish of the flats. In river oxbows and backwaters, extensive 5- to 7-foot flats extending offshore hold legions of fish. Here, perch swim along weedlines, poking into pockets for prey. A similar pattern develops at vast Leech Lake in Minnesota, where major portions of the lake are less than 12 feet deep. Fish wander among old clumps of weeds, feeding on bottom-dwelling invertebrates and schools of small minnows.

In other lakes, however, shallow flats hold mini-perch, young bait stealers that feed walleyes, eelpout, and anything else interested in a tasty if spiny meal. Larger perch and legendary “jumbos” hold deeper, perhaps in the 20- to 40-foot range. But areas with large flat zones are productive. In Lake Michigan, anglers often locate perch in water 50 feet deep, on bottoms of mixed sand, gravel, rock, and mud. Here perch feed on invertebrates.

But where to fish on such vast, relatively featureless areas? Humps or ridges that rise from a deep flat provide edges that may hold roving bands of perch. Predators like walleyes certainly use these areas as feeding zones to ravage perch as night falls. The bases of islands, reefs and mud flats offer edges that provide logical starting points.

Finding perch requires lots of legwork unless some adventurous buddies have already determined the location of a school. But beware. A report of a hot bite last week may or may not pinpoint action now. For large groups of perch roam, presumably to feed. Once they crop an area, it’s on to greener flats. Plotting their direction can be frustrating without a little teamwork.

Using The Data

The particulars regarding perch vision provide some unique insights into strategies for catching these robust and tasty gamefish. Their vision characteristic—great peripheral and long-range vision—means you can quickly ascertain the potential of a spot where you’ve drilled a hole. Aggressive lures like spoons make great search lures for perch. Knowing perch can see a spoon at a distance in clear water, you can quickly assess first their location; then their mood; and finally what bait might trigger them to bite. If nearby perch are at all aggressive, the bright flash should draw them to your hole. They may not bite, but at least we have location solved.

Jigging a spoon tipped with a minnow head or small minnow should soon attract any nearby perch. Understanding their vision, there’s no need to linger on an unproductive spot. Give them two or three minutes, then move on. That’s the first step. Converting hesitant fish to biters may require fine-tuning factors like lure color and size, jigging motion, and size of livebait.

Always have at least two rods for perching through the ice. Spool one with 4- to 6-pound line and add an active attractor, like a a 1/8- to 1/4-ounce spoon tipped with a minnow head or a perch eye. This calls ‘em in.

The second rod should be equipped with a more subtle presentation, like a simple split shot-hook combo for whole minnows, or a tiny 1/80- to 1/32-ounce jig tipped with a couple maggots and presented on 2-pound line. Or combine the two—attraction and subtlety—by removing the hook from the spoon and tying on a short 2- to 3-inch leader holding a tiny 1/80- to 1/64-ounce jig baited with a maggot or a perch eye.

Jump the spoon two feet or so, pause, jiggle, and jump it again to draw fish in. When marks appear on sonar, slow down and let the small jig and bait do the rest. We particularly like the 1/6- to 1/4-ounce Acme Kastmaster spoon for this technique because it falls fast and has a flat side that projects lots of flash, perfect for those far-seeing perch.
