Some Facts About Walleyes

My dad taught us kids how to fish when we were old enough to hold a pole. He used to laugh about having six kids so he has a bigger limit to take.

He'd say, "In order to catch a walleye, you need to think like a walleye." In order to do that, you need to know what's going on in that pea-sized brain of theirs

Walleye are closely related to saugers and belong to the perch family. They are not related to pike.

Walleye are often unpredictable, are constantly on the move and will bite like mad one day then disappear for a week for no apparent reason. And, when they decide to quit biting, almost nothing will change their minds.

Walleye have big marble-like eyes which have a layer of reflective pigment in the retina. This gives walleye a built in advantage – they can see well in dim light – but their most common prey, yellow perch, cannot. This highly developed night vision allows walleye to do most of their feeding at night.

Because walleye eyes are so sensitive to light, they don't like bright sunlight. If the water is clear and there is no shade in the shallows, walleye will go as deep as 40 feet to escape the penetrating rays of the sun.

Walleye can see color but lack the blue-yellow cells; it is though that they see everything as some shade of red or green. This means walleye can generally see red, orange and green lures better than other colors. However, the angler must remember that water color and depth change the way a lure appears to the fish. So, the best colors may change from one body of water to another or from one depth to another within the same body of water.

Walleye have an extremely sensitive lateral line system that allows them to detect minute vibrations in the water. This allows them to single out an erratically swimming bait fish or wobbling lure even in deep or murky water. This, in conjunction with their excellent eye site gives walleye a tremendous competitive advantage.

Walleye, when young, live almost exclusively on insects, and some scientists believe that there are some walleye (local to certain areas) that will live almost exclusively on insects throughout their whole life. Most walleye do switch to an almost exclusive minnow diet by the time they are in their second summer.

Walleye can, and do travel extensively within their waterbody. On large lakes, such as Lake Erie, walleye will travel up to fifty miles in a single night. Normally though, they won't travel more than several miles, unless in search of their favoured water temperature or food.

It is believed that walleye can ‘hear' a school of baitfish from quite a distance away, using the hearing sense of the lateral line. Most often the lateral line is uses for relatively ‘close range' hearing work.

Walleye have their ‘taste buds' in their lips - thousands of them!

Walleye are ‘long distance' swimmers, and few ‘prey' species can outdistance them. It is believed that walleye can ‘smell' their prey, quite a distance away, using their keen sense of smell. Too, they use their lateral line to find such schools of minnows.

Walleye have canine teeth, which are slanted back. They use these wickedly sharp teeth to catch/hold and tear their quarry.

Walleye are not especially cannibalistic, but will eat their ‘own kind' only if there is a low/limited food supply of other minnows/food.

Walleye, it's said, have a ‘soft mouth'. This is false, in fact the membrane around a walleye's mouth is hard and brittle. Because it is so hard and brittle, fish hooks/lures will easily tear and break out of a walleye's mouth, giving one the impression that the mouth is ‘soft'.

Walleye often ‘suspend' in water, especially over deep water. They do ‘lay' on the bottom, but not very often, and usually only for a short period in the early summer or mid-autumn season. Oxygen content on the bottom is not usually sufficient for them to stay on the bottom, unless it is a relatively shallow lake.

Walleye don't very often go deeper than 60 feet. Most often they are found in water between 20 feet deep and 60 feet deep, depending on the water temperature, bait, oxygen content, and time of day/night/year.

The dorsal fin spines and teeth of the walleye are treacherously sharp. They don't have any venom in them, but they often do have bacteria in the slime covering these needle sharp ‘jabbers'. It is not uncommon for an angler to ‘take a poke' from one of these wickedly sharp spines or teeth - and catch what is slangily called ‘fish poisoning'. This fish poisoning is a very painful infection from the aforementioned bacteria entering the fisherperson's wound. If this happens, you'll likely have to go to the doctor for a shot of antibiotics. This condition is easily treated by antibiotics, but is incredibly painful, and can take months to heal - if you don't seek medical help. USE LONG NOSE PLIERS OR HEMOSTAT WHEN HANDLING WALLEYE!

Walleye are a relatively clean fish, and have few diseases that people can catch. The one most susceptible to people is the tapeworm. - always thoroughly cook your walleye before eating it. There are some ‘people's' that have a custom of eating raw fish - I don't recommend this for any freshwater fish!

Walleye will sometimes have some very sad looking tumours on their sides, most often, early in the summer season. These look terrible, and many fisherfolk think they are cancerous - most aren't. These are a likely virus growth, and are only on the outside of the fish's skin. They can be ‘cut off', and the fish eaten. The only way that they can be proven as cancerous is by lab. testing. This growth doesn't affect the walleye's flesh. Even if they were cancerous - simply cut these grotesque and unsightly growths off, and the flesh under the skin will/should be OK to eat with no chance of the person eating the fish also catching the cancer - take no chances though - cook those fish - always!

Walleye have excellent hearing and when in shallow water a noisy boat will put them down. Avoid trolling over them, especially with a gas motor, and don’t drop anything that will cause noise as it bounces off the bottom of the boat.

If the water is clear and walleye are in the shallows(10 feet or less) it is generally better to drift or anchor and to cast into the shallows.

While walleye do have a good sense of smell, it doesn't seem to be an important factor in feeding behavior. In murky water a vibrating bait is much more effective than a bait that emits odors.

Walleye are opportunistic feeders and will eat just about any fish they can catch. Throughout much of the U.S. perch is their main food but they will also eat shad, trout, crappie, bluegill and other fish. They also readily eat crayfish, frogs, leeches, snails, mice and even small ducks.

Fishing success for walleye is highly influenced by the baitfish spawn. In the spring when few baitfish are present fishing is generally good (except during the spawn, when walleye don’t feed much). If the baitfish have a good spawn then by early summer there will be an abundance of small fish for the walleye to eat.

When baitfish are plentiful fishing success for walleye slows and will remain slow until the baitfish numbers are reduced, generally by late summer or early fall. If the baitfish spawn is poor, walleye success will remain good throughout the summer and will be excellent by fall.

The old wives tale that walleye don’t feed during the summer is false. Walleye are most active during the summer and feed heavily. There is generally such an abundance of food that the chance a walleye will hit your bait or lure is reduced. Still, the knowledgeable angler will catch some nice fish.

Walleye have been known to live as long as 26 years in cold northern waters, although a walleye over 15 years old is rare. How fast a walleye grows and how big it becomes is largely dependent upon the availability of food and the length of the growing season. In Canadian waters where there is a very short growing season and not much food a seven-year-old walleye may only weigh about two pounds. The same fish in a southern lake, with an eight or nine month growing season and abundant food, may grow to 15 pounds during that same seven year period.

Walleye in Minnesota grow well, especially when their food supply is abundant, and fish over 12 pounds are caught occasionally.

Female walleye grow faster, live longer and become much larger than males. In most waters males exceeding four pounds are rare.

Walleye are a cool water fish that prefer intermediate temperatures from 65 to 75 degrees; they don’t like water above 80 degrees. They will remain active when water temperatures drop into the high 30s; in Minnesota they remain active through the winter and can be caught through the ice.

Walleye prefer water that isn’t too clear. They seek out mudlines and water with suspended silt or algae. In clear lakes walleye seek out turbid zones near river mouths and areas where the wind keeps the water stirred up.

Walleye seek out rocky, shallow shorelines and reefs to spawn. The eggs are broadcast and fall between crevices in the rocks where they are protected. Some wave action is necessary to prevent the eggs from being covered with silt and to keep them aerated.

In Minnesota, walleye spawn in the early spring when water temperatures approaches 40 degrees. They seek out gravel areas in as little as two feet of water. The males move into the spawning areas first but they are not territorial and they do not build nests. A big female can produce almost 400,000 eggs but average production is about 50,000 eggs.

Walleyes remain in deeper water until spawning time approaches. A week or two before the spawn starts they begin to move into shallow water; they are still feeding at this time. They will move into the spawning areas after dark and then drop back into deeper water just before sunrise.

The spawning period generally lasts from one to two weeks but if the water warms rapidly, spawning can be completed in just a few days. A severe cold snap my interrupt spawning activity for several days. If there are repeated cold periods during the spawn, the females may reabsorb their eggs and not spawn at all.

An individual female usually drops all of her eggs on the same night but all walleye do not ripen at the same time and it is common for some walleye to just begin to spawn while others have been finished for a week or more.

After spawning the males stay near the spawning area for up to a month and begin to feed heavily. Female generally move out of the spawning area and do not feed for up to two weeks.

After a couple of weeks the big females begin to feed heavily and anglers who understand this cycle can get into some of the best fishing of the year.

Walleye are oxygen sensitive and avoid water with dissolved oxygen content below 4 ppm. They don’t seek out areas with higher oxygen levels. While it is true that windswept portions of lakes attract more walleye, they are there because of the abundance of food, not because the oxygen level is higher.

Given a choice, walleye seek out areas with slight to moderate currents rather than stay in slack water. Walleye seek out currents from inlet streams, narrows separating two basins or areas with wind-induced currents.

There are several things to look for when trying to figure out where walleye are in any body of water. Walleye look for anything different from their normal surroundings. If the bottom of a reservoir is mostly mud, walleye will look for sandy areas. If most of the lake is rocks, walleye will look for sandy areas. The transition zones between mud and sand or mud and rocks, etc. will hold the most fish.

Walleye will pick a particular depth and then follow it around the reservoir. They almost never cross wide expanses of deep water to reach a new area. More likely, they will follow a contour (particular depth) around the reservoir and over time will develop preferred migration routes.

Early in the year walleye prefer gradually sloping areas near or in shallow bays where the water is warmest. However by summer, when temperatures in the bays become too hot, the walleye will move into areas with steeper slopes and sharp breaks into deep water.

In shallow reservoirs walleye relate to subtle depth changes. A sunken island that rises only two feet above the bottom will attract fish. Old road beds, gravel pits, ditches, changes in the size of gravel or rocks, slope breaks, etc. will become focal points for walleye in the reservoir.

Live bait is a favorite choice when fishing for walleye. Several surveys show that live bait accounts of at least two thirds of all walleye caught in a given year.

The best live baits for walleye include minnows, nightcrawlers and leeches. Night-crawlers and leeches are the most common walleye bait on Mille Lacs and are fished a variety of ways; however the most popular way is attached to a spinner rig (worm harness).

Minnow imitating lures are also a good choice but it is often important to match the color and size to the natural baitfish in the water. Minnow imitating plugs with long, slender bodies and paint to resemble shad, perch or bluegill are very effective. Neutrally buoyant models are popular because they can be retrieved very slowly without floating to the surface of sinking deeper than you want them to go.
