Here at the University of Caen-Normandy, the treatment of histological samples (oysters’ tissues) continues. We have just observed the first slides. As a preview, this photo of a section of Ostrea edulis sampled in June at Langstone Harbour (Ortac condition). A beautiful hermaphroditism!

Using modern microscope to look at oysters’ tissues is a great way to understand the impacts of nutrient pollution and poor water quality on our oysters. This investigating might even help to understand the impacts on wider shellfish species that provide benefits such as food for other animals and humans, homes for smaller sea creatures, protection from coastal flooding, filtering, and cleaning coastal water, and mitigating climate change by carbon capture and storage.

And there is more. Being able to see this species under the microscope might also help us to identify any impact from other foreign items such as microplastics contaminations and diseases. Stay tune for more updates!

Thank you
