Walleye

About the walleye

Typical adult length: 12–25 in (about 0.6–5.8 lb)

Lifespan
Typically lives 10 to 15 years.
Habitat
Found in lakes and rivers, often over deeper structure, points, or drop-offs.
Diet
Feeds primarily on smaller fish, especially at night.
Baits & techniques
Jigs tipped with live bait, crankbaits, and live-bait rigs worked slowly near structure are effective.
Best season
Spring and fall generally produce the most consistent walleye fishing.
Best time of day
Low light, dawn, dusk, and overnight, is typically prime walleye time.

Estimating weight without a scale

Length-to-weight formulas like the one above assume a typical walleye shape for a given length - fisheries biologists call this the cube law. Real fish vary: a well-fed fish ahead of spawning season can weigh noticeably more than a lean fish of the same length, and body shape varies fish to fish.

Adding girth (the distance around the fish at its widest point) meaningfully improves the estimate, because it captures how deep-bodied this particular fish actually is instead of assuming average proportions for the species - use the calculator above and fill in girth if you can measure it.

Either way, treat the result as a solid estimate, not a certified weight - see our terms for why these numbers shouldn't be used for tournaments, regulations, or sales.
