The Minnesota Governor’s Fishing Opener is next Saturday and anglers are eagerly waiting to drop a line, hoping to reel in trout, bass, walleye and muskie. But the state’s unseasonably warm winter may have had an effect on fish hatch for some species.

 in the Fisheries, Wildlife, and Conservation Biology Department at the University of Minnesota, told MPR News the lack of snow and premature ice melt could affect the reproduction and survival of young fish — like walleye and yellow perch — in the springtime. 

“A really short winter and early ice off can mean that when those young fish hatch out, they’re not matched with their food source. And that can lead to just low survival and abundance in future years, but might not be as visible, you know, right now at the fishing opener,” Hansen said.

“We here in Minnesota rely on our cold winters to kind of prevent certain pathogens or invasive species from being able to establish, and in years when we don't have that long, cold winter, we have a lot of concern about what might happen,” Hansen added. 

Anglers have a lot to look forward to, said Brad Parsons, fisheries section manager with the Minnesota Department of Natural Resources.

“Walleye fishing will be really good and we really hope people can get out and enjoy it early in the season,” Parsons said in a statement. “But we have all kinds of other fish out there too and, particularly if the walleye aren’t cooperating, we encourage anglers try catching something else.”

Weather variability, such as harsh winters in some years followed by warmer ones, concerns Hansen in the longer term. Reproduction and survival will be key indicators in the future. 

In terms of interventions, Hansen said there’s an abundance of interest and active research into fish stocking — particularly, which species may be more resilient to new and changing climate conditions.

Before anglers head out, the DNR recommends checking out 

“Back bays of lakes are great for finding abundant bluegill and crappie. Northern pike are almost always willing to bite, and there are all kinds of other native species out there like sucker species, freshwater drum and others that can really provide a lot of action and good food fare.”

 is May 11, aligning with Mother’s Day weekend. Minnesota moms can take part in a free, virtual
