Britain's freshest online seafood retailer

Seafood delivery service for the UK.

When I opened my first fishmongers in 1996, my aim was to help people buy and eat the freshest, most sustainable seafood in the world and I still have the same aim. Our unique position on the Brixham quay, combined with our zero-waste supply chain means we can enjoy fresh fish today while being part of the solution to help protect fish stocks for the future.

Welcome to the Rockfish online seafood market, the Uk's best online fishmonger.
