Do you believe local fisheries can be successfully maintained through natural reproduction alone in your area?

Wisconsin DNR survey crews captured a record-setting 75.1 young-of-the-year walleyes per hour in southern Green Bay during fall 2026. This data surpasses the previous record of 64.7 fish per hour established in 2018.

Why it matters

The flourishing walleye population in Green Bay is fueled entirely by natural reproduction, reflecting significant water quality improvements since the 1970s. A 2026 tagging study suggests the fishery remains robust with an angler exploitation rate between 7.5% and 8%.

DNR crews identified 96.5 young-of-the-year walleyes per hour near Brown County Bay Shore Park during 2026 surveys. The fishery has been sustained by natural reproduction since the state stopped stocking in most areas in 1984.

The players

Wisconsin Department of Natural Resources

This state agency manages, protects, and restores Wisconsin's natural resources and public lands.

The details

Crews utilized boats equipped with electrical probes to temporarily stun and sample fish populations across southern Green Bay. These efforts confirmed that the top three walleye year classes on record have all occurred within the last eight years.

1984: DNR discontinued walleye stocking in the Fox River and Green Bay.
2012: DNR ended walleye stocking in the Sturgeon Bay area.
2021: Total walleye catch in Green Bay reached 318,101 fish.
2024: A new walleye tagging study was initiated by the DNR.
Fall 2026: DNR crews conducted the record-setting survey in Green Bay.

Culture Shift

The resurgence of natural walleye reproduction in Green Bay follows a pattern set by the 1970s Green Bay water quality improvement initiatives. This recovery demonstrates how long-term ecological stewardship can reshape local recreational landscapes.

Anglers can expect a highly productive environment as the strong 2026 year class matures into the fishery. The low 7.5% to 8% exploitation rate suggests that the current population remains sustainable for local recreational fishing.

The takeaway

The record-setting walleye survey results confirm the success of decades-long habitat restoration efforts in the region. Maintaining this trajectory will require continued monitoring of annual exploitation rates by state environmental agencies.
