Fisheries Biologist Laska presents findings from 10 year Wisconsin panfish study

The Wisconsin Department of Natural Resources (DNR) has reported promising results from its ongoing 10-year panfish study, which aims to enhance the size and quality of panfish populations across the state. During the Natural Resources Board meeting on December 11, 2024, Fisheries Biologist Alex Latska presented findings from the study, which began in 2016 and is set to conclude in 2026.

The study was initiated in response to concerns about declining panfish sizes, particularly bluegill and crappie, due to high harvest rates. Historically, Wisconsin's lakes allowed a bag limit of 25 panfish, which many anglers felt contributed to smaller fish populations. To address this, the DNR implemented three experimental regulations across 94 lakes, aiming to determine if reducing bag limits could improve fish sizes.

The results have been encouraging. The most effective regulation, known as the "15-5" rule, limits anglers to a total of 15 panfish, with no more than five of any one species. This regulation has shown significant improvements, with some bluegill populations increasing in size by over an inch and crappie by up to three inches. Notably, the study also led to the capture of a state record pumpkin seed, highlighting the potential benefits of these new regulations.

Public feedback on the regulations has been largely positive, with many anglers expressing support for more restrictive measures to ensure larger fish populations. However, some opposition was noted, particularly regarding the 15-5 rule, as it limits the number of fish that can be harvested, which may not align with the preferences of all anglers.

As the study approaches its conclusion, the DNR plans to propose new regulations based on the findings, targeting specific lakes that would benefit from continued restrictions. These proposals will be presented during the 2025 spring hearings, with the aim of balancing conservation efforts with the recreational needs of anglers.

The DNR is committed to ongoing communication with the public about these changes, ensuring that anglers are informed about regulations at boat landings and through various outreach efforts. The department aims to maintain a diversity of fishing experiences while promoting sustainable panfish populations across Wisconsin's lakes.
