State wildlife regulators in South Dakota have abandoned a plan that would have permitted anglers to harvest large muskellunge, deciding instead to preserve strict catch-and-release safeguards after sport fishers mobilized in force against the measure.
The decision was finalized during a two-day meeting of the South Dakota Game, Fish and Parks Commission held in Winner. Commissioners were considering a broader regulatory package that featured a controversial provision easing protections on the prized freshwater predator, commonly known as the muskie.
Under the agency's proposed rule change, licensed anglers would have been granted permission to keep a single muskie per day, provided the fish measured at least 45 inches in length. Agency officials had hoped the revision would generate fresh enthusiasm for the state's specialized muskie fishery.
However, the prospect of legalizing the harvest of trophy-class fish drew sharp resistance from dedicated anglers who insisted the change would jeopardize years of conservation progress. The existing mandatory catch-and-release framework was originally established in 2018, enacted after muskie enthusiasts lobbied state officials to protect the species so individual fish could attain greater size and longevity.
Public opposition to the rollback was underscored during the commission's public input session, where Sioux Falls resident Scott Vander Meulen presented a petition bearing more than 650 signatures from individuals opposed to the harvest rule. Additionally, more than 50 formal written comments submitted to the department voiced overwhelming dissent against allowing harvest.
Vander Meulen emphasized to commissioners that current regulations already provide the public with the opportunity to pursue trophy-sized muskies while ensuring the resource remains intact. He argued that releasing a landed trophy allows the exact same specimen to be caught by other anglers in the future, whereas harvesting the animal permanently eliminates that opportunity from the fishery.
Organized sportsmen's associations also stepped forward to contest the proposal. Dana Rogers, executive director of the South Dakota Wildlife Federation, testified before the commission that the federation’s muskie-angling membership stood firmly and adamantly against any relaxation of harvest limits.
Further criticism arrived from regional angling groups, including the Fargo-Moorhead chapter of Muskies Inc. In a letter submitted to the commission, chapter president Josh Karch pointed out that neighboring jurisdictions with harvest allowances generally maintain higher minimum thresholds, often establishing 50 inches as the baseline standard for keeping a fish.
Karch also noted that modern angling practices no longer require harvesting a fish to preserve the memory of a catch. He highlighted that high-quality synthetic replica mounts serve as an ideal alternative, giving anglers a tangible commemoration without removing vital mature breeding stock from the water.
Muskellunge occupy a distinct ecological niche as formidable apex ambush predators in South Dakota waters. Characterized by long, torpedo-shaped bodies, duckbill snouts, and rows of razor-sharp teeth, muskies conceal themselves in dense aquatic vegetation or among submerged timber to ambush prey, consuming a varied diet that spans other fish, insects, crustaceans, waterfowl, and small mammals.
Providing context on the state's fishery, Department of Game, Fish and Parks fisheries biologist Brian Blackwell presented an overview of the program's history and biological data. The state's dedicated muskie management initiative traces back to 1975 and currently oversees stocked populations in five key lakes, targeted at a low-density management goal of approximately one fish per five acres, while wild populations also exist in several other lakes and sections of the lower Missouri River.
Blackwell explained that wildlife officials had initially introduced the 45-inch harvest option to counter historically low levels of angler engagement with the program. Regulators had theorized that offering sport fishers the possibility of retaining a career-best trophy might stimulate broader participation in muskie fishing across the state.
Addressing population dynamics, Blackwell acknowledged that department biological sampling operations rarely encounter muskies exceeding the 45-inch threshold. He observed that active muskie anglers likely encounter larger specimens more frequently than state survey crews do, suggesting that future collaborative data-gathering partnerships between the department and the angling community could help bridge information gaps.
Confronted with unified opposition from sport fishers and conservation advocates, the Game, Fish and Parks Commission voted to remove the harvest provision entirely from the regulatory package. The outcome leaves South Dakota’s mandatory catch-and-release policy intact, ensuring all hooked muskies must continue to be returned to the water immediately.
