A conversation with John Holmyard, founder and managing director of Offshore Shellfish, 21st century mussel farming: guilt-free food that helps regenerate marine biodiversity and captures carbon. We talk about protein. With a growing population, we need more and more of it. So, what is the lowest impact and positive impact protein source we can grow? A deep dive into the largest offshore mussel farm in Europe, where they grow large amounts of mussels by grazing large number of plankton that naturally flows by. And, in case you are wondering, there is so much plankton around because we depleted most of the fish stocks that used to eat a lot of it.

We learn all about how to build the largest mussel farm in the UK and how to deal with regulators who have no idea what shellfish farming even means (they think you hunt mussels in the wild). We explore why mussels are such a potential crop to grow, and they can even restore natural mussel reefs, which used to be present all around the North Sea until we started bottom-trawling. And why are politics fundamental to the business when all of your crop goes fresh to mainland Europe?
