LINCOLN, Neb. – Many things can cue spawning in freshwater fish: weather, water temperature, moon phase, etc. One of the most important cues is the amount of daylight. For that reason, spawning tends to occur about the same time every year. So, the walleyes will be spawning April 1.

Not all fish in a population spawn at the same time. Some spawn early and some late. The result is the spawn period will last a period of weeks. Typically, males are the first to anticipate spawning; they “come early and stay late.” Male walleyes will be present on spawning habitats for days, even weeks, before and after peak spawning activity. Females stage near the spawning habitat, then move up when they are ripe and ready to spawn. Normally, females will deposit all of their eggs in one night of spawning activity.

Walleyes are broadcast spawners. Eggs and milt are scattered over spawning habitat. Neither parent provides any care or protection for the eggs or young.

Ideal spawning habitat for walleyes is rock a little big larger than gravel. That rocky substrate needs to be well-aerated by water flow, current or wind and wave action.

Nebraska waters have little rock in them, so walleyes use the next best thing – rock rip-rap or soil cement on the dam faces of reservoirs. During the spawn period, most adult walleyes will congregate on or near those dam faces, although a few fish will use other rocky habitats or even migrate up feeder streams or rivers.

Many Nebraska anglers consider the walleye spawn to be an opportune time to catch walleyes. That may be especially true for shore anglers as the walleyes congregate on the shoreline while spawning. Certainly, the spawn period is a time when the walleyes are concentrated in areas easily accessible
