We work to see that marine ingredients are recognised as the best and most important source of animal and human nutrition. 

We want to improve responsible fishery sourcing and production of marine ingredients globally and aim to keep improving the responsible sourcing and production of global marine ingredients through an accessible programme of certification. For MarinTrust, “responsible” describes the practices and behaviours that are expected of MarinTrust-certified sites, while “sustainable” is the goal to be achieved collectively by the marine ingredient sector as a result of these responsible practices and behaviours. 

Our ambition is for 75% of all marine ingredients to be MarinTrust certified, in application, in assessment or in the MarinTrust Improver Programme by 2025.

Our work

Marine ingredients play a pivotal role in aquatic and land animal feed as well as in the health supplement industry. We work to demonstrate that marine ingredients are responsibly sourced and produced through two international third-party certification standards:

Factory standard block


The Factory Standard (MarinTrust Standard) covers the sourcing and production of marine ingredients at the factory. The unit of certification is the factory, but the Standard ensures that the ingredients come from non-IUU fisheries that are well managed in accordance with the FAO Code of Conduct for Responsible Fisheries. It guarantees that production is carried out to high standards of safety and quality, with sufficient care given to the environment, workforce and local community. Learn more...
CoC Block


The MarinTrust Chain of Custody (CoC) Standard allows businesses in the supply chain to be recognised for their use of MarinTrust certified ingredients. These can include processors, packers, storage providers, oil refiners and traders, who can demonstrate that the marine ingredients come from a MarinTrust certified factory, maintaining full traceability throughout the value chain. Learn more...
IP Block


The Improver Programme (IP): The MarinTrust Improver Programme is dedicated to marine ingredient production factories involved in a Fishery Improvement Project (FIP). Through a structured, timebound process, they can develop and gain recognition for their sourcing of marine ingredients, while working towards certification. Learn more...

Value Chain

Half of the world's marine ingredients production is now certified against the MarinTrust standard. MarinTrust engages a diversity of stakeholders, from local regulators, international organisations, and other standards, to fishermen, marine ingredients producers, traders, feed producers, farmers, health supplements and pet food manufacturers and retailers. As a business-to-business organisation, MarinTrust doesn't engage consumers directly.

Who recognises MarinTrust

Working with other standard holders that share the same objectives for responsibility in the seafood industry is key for the success of the assurance of the industry.

  • The Best Aquaculture Practices (BAP) standard requires that 75% of marine ingredients shall be from certified sources (MSC or MarinTrust), or FIPs, from 2025, thus raising its previous 50 % bar.
  • The Sustainable Fisheries Partnership recognise MarinTrust.
  • Global GAP requires that 60% of marine ingredients shall come from certified sources (MSC or MarinTrust), or FIPs. The requirement will reach 75% as of 1 January 2025. 
  • The Aquaculture Stewardship Council (ASC)’s new Feed Standard announced in June 2021 uses an improvement model for marine ingredients which requires feed mills to source from more sustainable fisheries overtime. “MSC and MarinTrust, both ISEAL Code Compliant members, play a crucial role in this mechanism and form the keystepping stones for improvement” the ASC says. Intermediate steps are recognized FIP programmes

MarinTrust recognises:

MarinTrust formally recognises the following organizations:

MarinTrust is supported by international NGOs such as WWF, Sustainable Fisheries Partnership and CeDePesca, as well as by global initiatives such as The Global Food Safety Initiative. Credibility is further enhanced through MarinTrust’s ISEAL Code Compliant membership.
