About John Williamson Fishmonger

A Proud Family Tradition

For over a century, John Williamson Fishmonger has been a staple in the heart of Portobello, bringing the freshest fish and shellfish to our community. We are a fourth-generation, family-owned business with a passion for seafood that has been passed down through the generations. Since our founding, our mission has remained simple: to provide the finest selection of seafood, sourced locally from fishermen we know and trust, ensuring that every product meets the highest standards of quality and sustainability.

Our Story

Through hard work, dedication, and a deep love for the sea, our family built a reputation for supplying only the freshest seafood, with a focus on personal service and strong ties to local fishermen. Each generation of the Williamson family has brought new energy and ideas to the business, while always staying true to our roots. Today, we proudly continue to serve the people of Portobello, offering a wide range of fresh fish and shellfish with the same care and expertise that has defined us for decades.

A Commitment to Freshness and Quality

At John Williamson Fishmonger, we believe that the best seafood starts with freshness. That's why we source our fish and shellfish daily, ensuring that only the finest and freshest catches make it to our display. From the North Sea to your plate, we offer an unparalleled selection of locally sourced fish, including cod, haddock, mackerel, and more, alongside premium shellfish like lobster, crab, prawns, and mussels.

Our expert fishmongers are on hand to carefully prepare your seafood just the way you like it, whether it’s filleting, skinning, or even offering advice on how to cook the perfect dish at home.

Sustainability and Local Sourcing

We are proud to support sustainable fishing practices that help protect the future of our oceans. We work directly with local fishermen who share our commitment to responsible fishing, ensuring that our seafood is ethically sourced and as fresh as possible. By prioritising sustainability, we not only provide the highest quality seafood but also play a part in preserving marine ecosystems for future generations.

Our longstanding relationships with these local fishermen allow us to bring you the freshest catch while ensuring the sustainability of our coastal community. This dedication to ethical sourcing has been at the heart of our business for generations, and it’s something we’ll continue to uphold.
