Past Results

Between 2004 and 2007 citizens assisted with collection of crayfish for a research study about the effects of the invasive rusty crayfish on native crayfish in water bodies across Wisconsin. Citizens collected crayfish, then preserved them and delivered them to a local drop off site.  At their chosen field locations, citizens also collected a variety of water quality parameters (such as dissolved oxygen, pH, and conductivity). 

Researchers at the University of Wisconsin-Madison collected the crayfish from the drop off locations and identified them. Citizens were provided results of the type of crayfish found at their monitoring sites and the data were compiled in maps and scientific papers as part of a project about Aquatic Invasive Species by Dr. Jake VanderZanden and researcher Jeff Maxted.

Results of crayfish collections are available for 2004, 2005, and 2006. A report showing types of crayfish present in various waterbodies of the state up to prior to the start of the project and up until 2004 is also available.

Researcher Jeff Maxted developed a presentation: RustyCrayfishWIInvader (5.91 MB pdf) about the research being conducted on crayfish and implications of the invasive rusty crayfish.  This presentation is posted in pdf format for your information.

2005 Results

The following is a list of crayfish found during 2005. These are preliminary results, so they are coded by Site ID, which is a number that represents a stream, river or lake. A more user friendly report will come out later on, but in order to share findings with you now, this is what was available. WAV volunteers contributed a quarter of the crayfish collected during the sampling season in 2005. That's excellent! Thanks so much for your time everyone!

For information about the type of crayfish found at a site, visit the Milwaukee Public Museum's Crayfish information website at: www.mpm.edu/collections/research/invertebrates/wicrayfish/

O. rusticus is the invasive rusty crayfish.
