Scientists agree that next to habitat loss, aquatic invasive species pose the greatest threat to the decline of native aquatic species in North America.
Take our survey to help us identify priorities for our AIS work.
Aquatic invasive species threaten trout populations
The spreading of existing AIS, along with new AIS invasions and climate change is expected to have significant negative impact on TU’s efforts to conserve and protect native species across the country.
AIS impacts can be devastating — invasive lake trout and whirling disease have combined to cause a 90 percent decline in Yellowstone Lake’s Yellowstone cutthroat trout population — the world’s largest refuge of native Yellowstone cutts.
Gathering AIS information
TU’s AIS Program Director Dave Kumlien and researchers from Illinois State University have developed an aquatic invasive species survey. The survey will help TU identify priorities and develop AIS policy.
We need your help — give us about 5 minutes of your time to take the survey. We’ll ask a few questions about how AIS have affected your favorite places to fish, and some questions about your fishing habits.
No personal information is collected, and your participation is very important.
Tell your friends
Know of a fellow TU member or trout angler who would be interested? Be sure to tell them about the survey.
The survey will be active through the end of February 2012. Please take the survey only once. Thank you!
