Offshore Shellfish

Growing the UK’s first large scale rope cultured mussel farm

Welcome to Offshore Shellfish Ltd Proud to be Organic and BAP Certified

Offshore Shellfish Ltd is building the UK’s largest offshore, rope cultured mussel farm, in Lyme Bay, Devon, using specially designed technology to grow the blue mussel Mytilus edulis. Once completed, the development will also be the largest of its type in European waters.

 Our aim is to produce a sustainable source of high quality seafood in the open sea, as evidenced by our Best Aquaculture Practice (BAP) certification and Soil Association Organic certification.

We are a family run business with over 30 years’ experience in mussel farming. We work in harmony with the natural environment, and regularly monitor the impact of our activities, to ensure we maintain high standards.

Our mussels are appreciated by customers in the UK and Europe. 

Best Aquaculture Company 

Offshore Shellfish has been awarded the prestigious award of Best Aquaculture Company at the Aquaculture UK Awards and recognised for taking a new direction in marine aquaculture. 

Our Head of Operations, George Holmyard, also received the Best Shellfish Farmer award.

We are very proud of these accolades, we couldn’t have done it without our team of employees and our suppliers, who have all gone the extra mile for us. Thank you to everyone who has helped us on our way.
