Simulation study reveals adaptive harvest regulations outperform rigid policies in freshwater recreational fisheries, indicating tailored management balances conservation and angler welfare.

Key Points

To determine whether adaptive harvest regulations tailored to local stock status outperform rigid one-size-fits-all regulations across conservation, social, and economic goals in open-access recreational fisheries.
Coupled social-ecological simulation model developed for an open-access freshwater fishery featuring mobile, heterogeneous anglers targeting northern pike (Esox lucius).
Evaluated combinations of minimum-length limits, daily bag limits, and lake closures across scenarios varying in angler effort density, post-release mortality, and biological monitoring frequency.
Adaptive harvest planning combining flexible minimum-length and daily bag limits consistently outperformed rigid one-size-fits-all regulations across conservation, social, and economic criteria.
Closing collapsed lakes provided minimal extra protection under low post-release mortality, but substantially mitigated regional overfishing and preserved biomass yield when post-release mortality and angler densities were high.
Conservative fixed regulations with high minimum-length limits and low bag limits served as a viable secondary alternative when stock monitoring was restricted, though at the expense of regional biomass yield.
