Marbled crayfish
The marbled crayfish (Procambarus virginalis), also known as the marmorkrebs, is an invasive freshwater crayfish species with a unique ability to reproduce via parthenogenesis, meaning all individuals are genetically identical femals capable of rapid population expansion. Although not yet widespread in the UK, it poses a significant ecological threat due to its potential to outcompete native spceies, disrupt ecosystems, and spread diseases such as crayfish plague (Aphanomyces astaci). Its presence in European water systems highlights the need for vigilant monitoring in the UK.
eDNA testing (environmental DNA testing) offers a non-invasive method to detect crayfish populations. By analyzing water samples for genetic traces shed by the species, eDNA testing provides a highly sensitive and specific tool to confirm its presence without the need for traditional visual surveys.

How does it work?
Step 1: Buy your sampling kits in the Shop
Our sample collection kits ensure the DNA in your samples is preserved and protected during transit to our laboratory. We have kits for water, soil, scat and more.
Step 2: Collect your samples
Our molecular ecologists can advise you on sampling strategies and how to make the most of your budget
Step 3: Order your testing in the Portal
Register your samples online. Tell us which tests you want to order for each sample. Return the samples to us. We invoice you for the testing upon completion (we do reserve the right to charge for testing upfront if it is your first order). Alternatively, you can email your testing order to our team using the email in your kit.
Step 4: Receive your results
Your results will be sent to our secure online portal. If you need it, we can offer a free consultation to help you interpret your results.
