Fishing is a popular outdoor recreational activity in the Northwoods region, and it has played a significant role in driving the local economy. The lakes and rivers in the area are home to a diverse range of fish species, but as temperatures have increased over the years, there have been concerns about how this change may impact fisheries.
Since 1950, Wisconsin temperatures have risen by about 2 to 3 degrees. Projections indicate that this trend will continue, with further increases of up to 8 degrees possible in the next 25 years. As the climate changes, it is anticipated that there will be impacts on the fisheries in the area.
Research fish biologist Holly Embke with the USGS Midwest Climate Adaptation Science Center has been studying these changes and their effects on fish populations. She notes that there are already observable shifts in fish populations due to warming temperatures. Warm-water fishes like bluegill and bass are increasing, while cold-water species like walleye are facing challenges. Shifts in ice-off dates could potentially threaten walleye spawning, as indicated by a recent study. Despite these challenges, Embke emphasizes that there is still hope for the future of fisheries.
To address these challenges, Embke focuses on identifying struggling fish populations and determining ways to help them adapt to changing conditions. This may involve habitat restoration efforts or supporting other fish species that are more likely to thrive in new conditions. The goal is to ensure that fisheries remain healthy and productive despite climate change.
Embke will be discussing these challenges and sharing her insights at an upcoming Science on Tap Minocqua event on Thursday, April 4 at Rocky Reef Brewing Company in Woodruff starting at 6:30 p.m. The event will also be available for streaming online for those unable to attend in person.
Her presentation aims to provide attendees with a better understanding of potential changes in fish communities due to climate change while also highlighting opportunities for supporting and protecting aquatic ecosystems.
In conclusion, fishing remains an important outdoor recreational activity in Northwoods region; however, changes in temperature have already started affecting fish populations and projections indicate further impacts ahead due to climate change. It’s important for us all to understand these changes so we can work together towards ensuring healthy and productive fisheries for generations
