The overarching goal of this experiment is to determine the carbon dioxide (CO2) concentration needed to cause movement of Faxonius rusticus and Procambarus clarkii away from the source. Time of exposure will also be evaluated, and depending on their size, some crayfish may need to be exposed to the CO2 longer than others in order to see an affect. This method may be further tested as a way to remove invasive species from small bodies of water without harming the crayfish.
