Shad
Shad, including the twaite shad (Alosa fallax) and allis shad (Alosa alosa), are migratory fish species found in the UK. These members of the herring family migrate from the sea into freshwater rivers to spawn, typically preferring large, clean rivers with gravelly beds. Shad populations in the UK are of conservation concern due to habitat loss, pollution, and barriers to migration such as dams and weirs. These fish are ecologically significant and are protected under European and UK legislation.
eDNA testing (environmental DNA testing) offers a non-invasive method to detect shad 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.
