Around 18,000 oysters were introduced more than two centuries after they were wiped out. By feeding on nitrates and plankton, they are helping to clear algae to improve coastal biodiversity and marine habitat.It was an honour to welcome Fiona back onto the podcast, especially hearing her inspiration for the institute, including a passage from James Joyce’s Ulysses on water – we’re going to share this on our socials so make sure to check it out!🔔 We hope you enjoy the episode and make sure to follow and subscribe to our channels to get alerts on the episodes.
