About our fish

We guarantee that all our fish are responsibly sourced. Like
our fresh handline-caught tuna

All the fish that is included in Waitrose own-label products has been responsibly caught or farmed. This means our suppliers must only source fish from fisheries or farmed aquaculture operations that are responsibly managed. We have been working to this strategy for over 15 years. 


Fish specialists

Waitrose & Partners has fish specialists in most of its branches who can advise on what fish to buy.

Our fish specialists are trained at London's Billingsgate Seafood Training School. Not only can they gut, clean and fillet fish, they also know how to cook every species we sell.


Waitrose & Partners supports the Greenpeace campaign to end the sale of tuna caught with the use of fish aggregation devices used in conjunction with purse seining. We will not introduce any own label or branded tuna products produced from tuna caught in such a way.

All our own label skipjack tuna is pole and line caught in the Maldives. Since April 2013 all the skipjack tuna used in our business, both canned and in salads and sandwiches, has been certified as sustainable by the Marine Stewardship Council (MSC).

Scottish salmon

Waitrose & Partners farmed salmon comes from a small group of carefully selected farms based in the Shetland Islands, Orkney Islands and the Western Isles of Scotland. Each site is carefully located in high energy sites with strong tidal flows to ensure the highest welfare and minimise the impact on the environment. Strong tidal sites keep the seabed clean and also help encourage lean and fit fish, resulting in firmer flesh.

We have long-term working partnerships with our farmers. This allows for long-term planning and early adoption of practices that lead to improved quality and sustainability of the farming operation. To ensure the farm is having limited impact on the environment, submerged cameras are used to watch the fish feeding. This allows the farmer to ensure minimal, if any, feed is falling on to the seabed as this can cause pollution. The farmer can stop feeding the fish when he can see that feeding is slowing up. The latest feeder designs include features that prevent any food from falling on the seabed. On a six monthly basis the farmer will arrange for a survey to be carried out on the seabed around the site to assess the richness of the environment.


Site location is very important to reduce the interaction between wild and farmed salmon. Our farms are carefully located to minimise interaction with wild fish and every effort is made to improve ways of working between farmers and anglers, through improved communication, transparency and collaboration projects.

Measures to prevent seal deaths on salmon farms 

Waitrose & Partners requires all its farmed salmon suppliers to take rigorous non-lethal measures to deter predators, including seals. These measures focus on physical exclusion, including the proper use of acoustic devices, tensioned and weighted nets and the efficient removal of dead fish, which can attract seals. 

Having said that, seals sometimes get through all the non-lethal barriers our suppliers can put in place. This has resulted in attacks on the fish, causing serious welfare problems. This issue affects all major food retailers, however we are working with our suppliers to minimise the threat of predators.

Waitrose & Partners English rainbow and organic brown trout are supplied by Trafalgar Fisheries perfectly situated in meadows adjoining the River Avon, just south of Salisbury.

The fish are reared at low stocking densities in gravel and earth ponds fed by the clear waters of the Hampshire Avon. The relationship with Trafalgar Fisheries and Waitrose & Partners has evolved over many years and is based on openness and trust. We share the common aim of ensuring that all our fish are reared to the highest welfare standards with respect on the environment to produce great tasting food.
