GREEN BAY, Wis. (WFRV) – It’s an annual tradition in Wisconsin for fishers to hit the ice and spear their sturgeon.
Sustainably Speaking: The potential harms of microplastics to people & the environment
Behind those dark shanties dotting the ice and the cheers at registration stations is a carefully managed process and conservation effort led by the Wisconsin Department of Natural Resources (DNR).
Sturgeon spearing season typically runs for up to 16 days, but it often wraps up sooner because the DNR sets strict harvest caps before the season begins. The DNR’s quotas are based on extensive biological data that often changes by year.
If the harvest cap is approaching the pre-set cap for any of their categories, the DNR can close that portion of the season early to protect the breeding population.
Lake sturgeon are long-lived and slow-maturing fish. Females may not spawn until they are 20-25 years old and they do not reproduce every year, making careful management an essential process.
Biologists use population assessments, age and growth studies, spawning surveys, and many other factors to determine what percentage of the population can be harvested without creating long term effects.
Every surgeon harvested must be registered at an official DNR station. During the spearing weekend, officials measure, weigh and tag each fish.
The DNR updates harvest totals daily, allowing managers to track progress toward quotas in real time. This transparency ensures anglers and conservationists can see how the season is unfolding.
The DNR takes special care to protect the spawning stock, or large egg-bearing females a critical step to produce future generations. Quotas may slightly increase in years where the population is especially healthy.
In less healthy years, quotas may decrease. This type of adaptive management will allow the spearing weekend to remain culturally significant and biologically sustainable.

Lake sturgeon were once very overharvested in the late 1800s and early 1900s. With the process of strict regulations, habitat protection and decades of scientific management, the Lake Winnebago population is now considered stable and self-sustaining.
The spearing season is not just a tradition – it is a model of how regulated harvest can coexist with conservation science.
