Craywatch

Invasive self-cloning crayfish are on their way to a stream or lake near you!

We need your help to monitor our waterways for the invasion of new species of crayfish. High on our priority list is Marmokrebs, a species that reproduces asexually – making it an extremely successful intruder in pristine ecosystems. Let’s make sure we know exactly where this and many other potentially invasive species are headed!

Take pictures of crayfish and tell us where and when you found it. The goal of this project is to help monitor waters for introduction of new and potentially invasive species of crayfish.

Invasive crayfish have had devastating effects in many freshwater ecosystems across the world, often driving local fish and invertebrate species to extinction. With your help, we can make sure to prevent this from happening here! Thanks in advance for helping us in this important project!
