Crayfish Movement Ecology

August 2022 - December 2024


Personnel

Participating Agencies

Invasive crayfish are increasingly common around the world, including in Missouri where there are over 30 documented invasions. These invasions disrupt the functioning of native ecosystems, threaten native species, and have economic consequences. Despite their importance, we know little about how fast the invasions occur or about the movement ecology of crayfish. This project will use expertise from the Missouri Department of Conservation and the USGS Missouri Coop Unit to investigate movement capacity for multiple invasive crayfishes. Results from the the study will inform managers of how long they have to enact conservation measures before invasive species spread to new areas.
