Project Results
This project has been ongoing since 2004. Results of crayfish collections by volunteers and sometimes by others, such as WDNR biologists, 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.
For more information about the project and related research visit Dr. Jake VanderZanden’s website.

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.
