A purposeful mission to produce the most sustainably sourced, low-carbon, canned tuna...
for those who want to make responsible seafood purchasing choices.

Anchored in tradition and crafted from pole & line caught, yellowfin tuna... our premium-cut, protein, omega-3 and selenium-rich canned seafood is caringly hand-cut, hand-packed and once-cooked, and our end-to-end ownership from boat-to-can gives immutable traceability to the very fisherman who caught your tuna.

About Us

THE WHY: Destructive overfishing is emptying our oceans. As a global community, we need to find new ways to manage this vital resource. We are challenged by a growing population and a food value chain that accounts for 25-30% of total greenhouse gas emissions. So, do we give up on our efforts to become more sustainable and responsible… or, can we choose to get better at it?


THE WHAT: PUREST CATCH is our brand and people, product, passion and purpose underpin our mission. We truly believe our canned tuna 'ticks more boxes' than those products available in the canned yellowfin tuna space today. 

THE HOW: Enabled by sustainably minded investors and retailers, and the artisanal fishermen on the British, South Atlantic territory of St. Helena Island, we are delivering a responsible and socially acceptable product produced only from tuna caught using mandatory pole & line, rod & reel or handline methods [One hook, One line, One fish at a time].

THE WHERE: The British territory of St. Helena Island lies within the tropical South Atlantic Ocean and our cannery is located here. The island sits within UN FAO-47, is surrounded by a 200 nautical mile radius (172,000 square mile), Category VI, Marine Protected Area (MPA) and Mission Blue Hope Spot, and is managed by the UK's Marine Management Organisation (MMO). The MPA also receives support from the Blue Marine Foundation. Importantly, for our company, the island's fishery has exclusive rights to fish.

THE GOOD NEWS: The wider global tuna fishing industry is challenged to find ways to undo decades of marine ecosystem destruction due to constant overfishing, the unregulated use of drifting FAD's, and the lack of investment into sustainable sourcing methods and technologies. The traditional, mandatory One-by-One methods adopted by both the St. Helena Government and its fishery, plus the science-led quota management and responsible harvesting strategy, with a minimum catch size regulation, is paying dividends. With the island's tuna fishery healthy and thriving, our consumers are assured that they will enjoy sustainably and responsibly sourced, premium quality, canned yellowfin tuna from our special artisanal fishery for generations to come.

Our Philosophy

We are preserving the right to work fairly and honourably, and will build on the spirit of respecting our purpose, our people, our company and our partners.

A product reflects the heart of its maker, so we will never attempt to please our consumers by cutting corners through mass production with/of uncertain quality.

We will always apply all efforts to develop our company into one that assures us of our consumers' trust.

Our product is a true reflection of our interpretation of consumer centricity, and we will always maintain a mindset that seeks ways to simplify consumer complexities and confusion.

We must always remain united to make our company one that we are proud to work for, and our business decisions will not be made on merely following the practices of "most other companies".

Our mindset will always be "when we think we're doing enough, the real work begins".


To achieve our goals, our targets must be clearly known and understood, so we will be resolute in our determination to uphold and exceed our values and ambitions, because if we compromise, we won’t make a difference. 

To succeed, we will tenaciously persevere in our efforts to uphold our principles and our promises, and we will always wrestle in the 'centre of the ring' to deliver on these, but with communication and a warm-hearted virtue that brings an understanding of our actions and our reasons.   

“For too long, we have been far too aggressive about extracting ocean wildlife and not appreciating that there are limits and even points of no return.”


Our Cannery

NO MIDDLE MEN: We will have direct ownership (from vessel to can) of every fish processed, assuring the consumer has immutable product TRACEABILITY.  

QUALITY: IKEJIME and SHINKEI-JIME practices with strict measures for maintaining a continuous COLD-CHAIN from the moment of catch through to processing, is mandatory. This locks-in freshness and quality thus assuring our consumers that their tuna retains the highest possible content of the all-important, health benefiting, nutritional attributes.   

GREEN CANNERY: Tropical locations lend themselves to being ideal for harvesting 'green' energy. With the ambitions to be powered as far as possible by Mother Nature, we are committed to investing in the technologies and innovations to achieve carbon neutrality.

GREENER FISHERY: Already a low-carbon fishery, we are committed to further reducing the carbon footprint of our vessels and ultimately your tuna, and we will work with industry experts and partners to promote and trial all available, affordable solutions.

PLASTIC:  Our entire shelf-ready packaging from cover-to-can is plastic-free, paraben-free, FSC accredited and 100% recyclable, and our fishermen are incentivised to remove marine debris and plastics from our ocean. Our ultimate goal is to become an end-to-end, carbon- and plastic-neutral operation.

THE GREEN FISH FAMILY: As the heartbeat and backbone of our operation, our people will have permanent, non-seasonal employment and will all receive fair pay and conditions, be treated fairly and respectfully, and most of all, valued. 


We are 100% committed to the UN SDG charter, and from the very outset we are adopting goal nos. 5, 8, 10, 12, 14 and 17.

Our Fishery - St. Helena Island

PUREST CATCH: For more than 400 years, fishing has been a way of life for the people of St. Helena. The artisanal fishermen operate from 20 traditional inshore boats under the umbrella of the St. Helena Commercial Fishermen's Association (SHCFA), and today they fish the same tuna grounds, using the same methods their fathers, grandfathers and great grandfathers fished for centuries before them.


A SUSTAINABLE FOOD FUTURE: As a member of the International Pole & Line Foundation (IPNLF), we guarantee that our tuna will only be harvested using the One hook, One line, One fish at a time (one-by-one) method, because protecting our ocean's biodiversity and the long-term success of our business and our fishery is paramount.


INTERNATIONAL COMPLIANCE: St. Helena Island is also an active member of the International Commission for the Conservation of Atlantic Tunas (ICCAT).


OUR FISHERMEN: Many of today's captains are third- or fourth-generation fishermen. As with most small island communities, fishing is a key industry and touches every member of the wider local community. Our fishermen are resolute in their determination to continue to fish using traditional pole & line methods, showcasing their fishery as being the most sustainable.

QUOTA MANAGEMENT: Data and science determines the annual quota allocations, always ensuring the fishery remains a responsibly managed one. Healthy stocks are maintained by prohibiting the landing of juvenile fish and a minimum catch size regulation is in place. As an active member of ICCAT, the St. Helena authorities are committed to effective and long-term quota management and mindful allocation. 


TRANSPARENCY and TRACEABILITY: Catch data is recorded against each boat upon daily landings, giving the consumer complete assurance that their tuna has been harvested responsibly, and guarantees 100% traceability from catch-to-can-to-table.
