Wisconsin DNR Launches Study on Panfish Populations
MADISON, Wis. — Contrary to their name, panfish thrive not in butter but in Wisconsin’s abundant freshwater ecosystems. The Wisconsin Department of Natural Resources (DNR) is kicking off an in-depth study of these popular sporting fish, including bluegill, black crappie, and yellow perch, which accounted for 75% of fish harvested in state lakes over the past decade.
Launched in July 2019, the study aims to understand factors affecting panfish populations, such as angling practices, predators, and environmental changes, with results expected by June 2026. Researchers will survey angler experiences and conduct field experiments, examining how water temperature, size, and clarity impact fish maturation.
The DNR is also investigating long-term conservation strategies, utilizing experimental regulations like the 15/5 rule to bolster specific panfish populations. Notably, declining species like walleye have prompted concern over ecosystem health, and understanding panfish dynamics could help maintain ecological balance.
As part of a broader research effort, this study seeks to inform future policies and ensure sustainable fish populations in Wisconsin’s waterways, ultimately preserving both recreational fishing and the state’s natural habitats.
