Walleye Fishing: Light, Depth and a Slow Retrieve

Start with the eye

The walleye’s name is also its instruction manual. Wisconsin’s Department of Natural Resources describes the species’ distinctive eyes — silvery opaque marbles that glow in the dark — and explains the reflection as the work of the tapetum lucidum, a light-sensitive membrane inside the eye.

That membrane sets everything else. Because their eyes are highly sensitive to light, the agency writes, walleye linger in deeper, darker water during the day and move to shallower water near bars, shoals and weed beds to feed as the sun sets.

So the question “where are the walleye?” is really the question “where is the light?” — and the answer changes twice a day.

Fish slowly, and near the bottom

Wisconsin’s DNR gives the retrieve in one line: keep the lure or bait near the bottom and reel it in slowly, because walleye are slow, deliberate biters and it is best to give them a chance to swallow the bait.

That is the single most common adjustment for anglers arriving from bass or pike fishing. A walleye does not usually announce itself. The agency also notes they are not spectacular fighters but put up a steady battle, always pulling for the bottom.

The species is a bottom-oriented open-water traveller: it lives near or on the lake bottom and moves through open water in loosely formed schools. There is a caution attached — walleye seldom congregate in any particular spot for long, a fact the agency says confounds even the most astute walleye anglers. Yesterday’s spot is a starting point, not a plan.

What they are hunting

Walleye are described as nocturnal predators that feed on unwary, often resting fish. Bullheads, freshwater drum, yellow perch, darters and minnows are named as favourite prey, with crayfish, insects and worms rounding out the diet.

The relationship with yellow perch is worth understanding because it runs both directions. Each species preys on the other at different points in the life cycle: large walleye eat yellow perch, while yellow perch eat walleye fry. Where too many adult walleye are removed from a water, the perch population increases from lack of predation, the perch become stunted as they compete for limited food, and few young walleye survive the extra predation pressure to reach adulthood.

Methods, and the honest hit rate

The agency’s own list is deliberately broad — still fishing from an anchored boat with live bait, trolling with spinners, drifting with the wind or current, fly casting with streamer flies or poppers on quiet calm nights near the edges of rocky bars or weed beds, bait casting with minnows, worms, night crawlers, spoons and plugs, and ice fishing with tip-ups or jigs.

Its summary of that list is refreshingly plain: there are a lot of different ways to catch walleye, and you may have to try them all.

It is equally plain about effort. Although fishing surveys show walleye is Wisconsin’s most popular sport fish, the agency warns not to assume it is an easy one to catch, and puts the expectation at at least eight hours on the water for every walleye in the pan.

That figure is a useful antidote to forecast optimism. The Escanaba Lake creel study found the same thing from the data side: for walleye, angler-related variables such as guide status and bait type outweighed every environmental factor measured, though low-light conditions did register a real positive effect.

Spring: the one predictable window

Between mid-April and early May, walleye migrate to wind-swept rocky shorelines, flooded wetlands or inlet streams with gravel bottoms to spawn. The distances can be long — Lake Winnebago walleye may swim 100 miles up the Wolf River to reach suitable spawning habitat.

Males arrive first and outnumber females seven to one. Females move into shallow water, typically four feet deep or less, and an average female lays about 50,000 eggs, usually spawning out completely in one night. Eggs hatch in 26 days at 40°F, 21 days at 50 to 55°F, and 7 days at 57°F.

Wisconsin’s DNR notes the fish bite readily during the famous Winnebago system runs, and are likely to reward even the unluckiest of anglers. It also notes that walleye fishing quality varies year to year, because successful year classes depend on spring flooding of spawning grounds — a dry spring hurts that year’s hatch.

Handling, and one health note

Catch and release is common practice, and the agency’s guidance for it is specific: do not land the fish. Reel it alongside the boat and gently remove the hook, or cut the hook off with a wire cutter. If the hook has been swallowed, cut the line and let the fish go — the hook will gradually disintegrate. Our catch and release guide covers the wider handling picture.

Large older walleye destined for the table should be eaten with more care. They can accumulate PCBs, pesticides or mercury as they feed on smaller fish containing trace amounts, and state agencies publish fish consumption advisories listing affected waters.

Walleye pressure is not trivial either: Wisconsin’s DNR estimates anglers hook 25 to 35 percent of the entire adult walleye population every year, which is why the state stocks 50 to 80 million fry and about 3 million fingerlings annually.
