A lifelong love of seafood

Mitch grew up in Weston-super-Mare and it was in his grandmothers kitchen that his earliest food memories would form. He opened his first fishmongers in 1996 with the aim was to help people buy and eat the freshest and most sustainable seafood in the world. 26 years of experience later he still has the same aim. Through the Rockfish restaurants, and online seafood market, Mitch has introduced thousands of people to the incredible fish available in Southwest waters. With his range of tinned British seafood, available online and wholesale, he has reached even more people, and been able to preserve the precious catch to enjoy year round.
