Coldwater Fish in Wisconsin Carly Krueger BIO 171: Animal Biology Lab 2 December 4, 2014
Wisconsin’s Water Mostly Cold Water Streams and Lakes Some Warm Water Streams and Lakes “In addition to over 10,000 miles of managed trout streams, another 22,000 of Wisconsin’s 54,000 stream miles may be suitable for cold water species…” (Mitro, 2010, p. 6) Coldwater Fish Need Water Temperature to Be 22°C
How Climate Change Affects Water Temp Sun Heats Water Top is Naturally Warm, But Bottom is Naturally Cold Bottom is Getting Warmer Coldwater Fish Will Decrease
Warm Water Fish Will Warm Water Fish Replace Coldwater Fish? Coldwater Fish Decrease Substantially Warm Water Fish Increase
Economy Culture Money Warm Water Fish Not the Same
What Can We Do? Groundwater Help Streams and Lakes With Highest Potential Don’t Help Streams and Lakes That Won’t Benefit From Management
