Sustain Sustainable Fish Advice

What can manufacturers and suppliers do?

As a food manufacturer or fish supplier, we realise that many companies may already have the capacity to supply sustainable fish, but may not be communicating this to their customers, or receiving requests for sustainable fish. As long as your supplies are demonstrably sustainable (and we will need to check), we hope to be able to publicise your work and help get you more trade.

How can larger manufacturers and suppliers help?

If you run or work for a larger supplier of fish and seafood, you could make a significant difference in helping London become a Sustainable Fish City. Download the Sustainable Fish City pledge and discuss it with your colleagues. By signing the pledge, and returning it to Sustainable Fish City, you will be committing your organisation to take the appropriate steps to buy sustainable seafood, to protect precious marine environments and fish stocks, and good fishing livelihoods.

Please get in touch to discuss your needs and concerns. Call Sustainable Fish City on 020 3559 6777 or email:

If you've already taken action, then get in touch and we'll feature your story on this website, as an inspiration to others to join in.

How can smaller manufacturers and suppliers help?

We recognise that it is harder for smaller and independent suppliers to find sustainable fish supplies, particularly if this is only one of several lines that you supply, and to find the time to undertake the necessary research and product development. You can tell the fishermen and other suppliers you work with not to supply endangered species, and to help you buy demonstrably sustainable fish, but even then, they may not be able to help you.

 To support Sustainable Fish City, we therefore ask you to:

  • Sign the Sustainable Fish City pledge.
  • Tell us (privately) who supplies your fish. We are keen to map the fish supplies for London, and then to work out the best ways to help them improve the sustainability of their fish, for the benefit of everyone.

Keen to join in? Get in touch, and we'll tell you what we can do to help.

Mike Berthet, M&J Seafood“Most leaders in the foodservice industry, whether individuals or corporate companies, have already started down the path of sustainable sourcing of fish and seafood. So if you are not on board then you will get left behind.”
Mike Berthet, M&J Seafood

Charles Redfern, Fish4Ever“We all need to start acting and thinking sustainably. We think that as a company or a brand we need to represent the best choice for a consumer."
Charles Redfern, Fish4Ever

David Attwood, Loch Fyne Oysters“We encourage other businesses to get involved, otherwise what type of legacy will we leave to our grandchildren regarding the fish that will be swimming in the oceans in 2050?"
David Attwood, Loch Fyne Oysters

Sustainable Fish: A campaign to protect precious marine environments and fishing livelihoods, and call for fish to be bought from sustainable sources. We want to show what can be done if people and organisations make a concerted effort to change their buying habits.
