MarinTrust is an international third-party certification programme for marine ingredients and is owned and managed by Marine Ingredients Certification Limited.

Note: Shall be written all as one word, with a capital M and capital T. 

MarinTrust Programme

MarinTrust Programme  is an international third-party certification programme which consist of:

  • The MarinTrust Standard
  • The MarinTrust Chain of Custody (CoC) Standard
  • The MarinTrust Improver Programme
MarinTrust Standard

The MarinTrust Standard is a third-party certification for marine ingredient producing sites that helps them demonstrate the responsible sourcing and production of their products such as fishmeal and fish oil.  

MarinTrust Chain of Custody Standard

A set of measures which are designed to guarantee that the fishmeal and fish oil products put on the market and bearing the MarinTrust logo are really products of designated origin that come from a MarinTrust certified factory.

These measures cover the tracking and traceability of processes, documentation and the product to maintain its integrity along the entire supply chain. 

MarinTrust Improver Programme

The MarinTrust Improver Programme is a structured, timebound process, through which marine ingredient production factories sourcing from improving fisheries (i.e. Fishery Improvement Projects) can gain recognition of their production. 

Marine Ingredients

Marine ingredients are nutritious natural products derived from marine organisms such as fish, krill, shellfish and algae. They are used mainly for aquafeed (75%), land animal feed, pet food as well as for human consumption in the form of health supplements.

The majority of marine ingredients are fishmeal and fish oil, derived from small pelagics (such as anchovy, sardine, menhaden and herring), and a growing volume comes from by-products (offcuts or trimmings). Fishmeal and fish oil provide essential nutrients for human health, indirectly through the farmed animals that we eat and directly through the consumption of fish oil capsules. Just as fishmeal and fish oil play a vital role in the growth and health of farmed animals, these essential proteins, fats, minerals and vitamins are then passed onto humans.

In short :

  • High productivity: For the last 25 years, the production of fishmeal and fish oil has been relatively stable at approximately 5 million tonnes of fishmeal, and 1 million tonnes of fish oil.  Supply has not increased alongside the increased need for aquafeed volume.
  • Multiplier effect: 1kg marine raw material gives 5kg farmed fish across global production systems. Thus, fish which do not have a food market are converted into 5 times the volume of fish that people do want to eat.
  • Decreasing impact on ecosystems: 1/3 of fishmeal is now produced from by-products, using what was previous waste and develop it instead as another valuable raw material from which fishmeal and fish oil may be produced.


Oversight system

The oversight system refers to the measure put in place to safeguard the impartiality and independence of the certification process. MarinTrust's oversight system is comprised of MarinTrust as the certification scheme and appoints independent, accredited Certification Bodies (CBs) to carry out all fishery Assessments, facility audits, and certification activities who have the sole authority for certification decisions. CB accreditation is granted by independent Accreditation Bodies (AB) who ensure CB adherence to ISO/IEC 17065 and MarinTrust requirements.


Quality Management System

The Quality Management System (QMS) is a set of documents which provide details of activities, procedures and responsibilities of the certification process to ensure the consistent and robust implementation of the Programme.

These documents include: structures,  programmes, practices, procedures, plans, rules, roles, responsibilities, relationships, contracts, agreements,  documents, records, methods, tools, techniques, technologies and resources.


Shadow Audit

Is the process in which a candidate auditor, who is in the process of becoming an approved auditor (either MarinTrust Standard or Chain of Custody Standard), observes an approved MarinTrust auditor conducting an audit against the relevant standard following successful completion of applicable MarinTrust training and passing of the exam(s).


Standard refers to the independently developed document which outlines the set of rules or requirements that participants must demonstrate they are able to meet in full for a particular service to achieve certification.

The MarinTrust Programme is comprised of the following standards:

  • MarinTrust Standard
  • MarinTrust Chain of Custody Standard
Standard requirements

Standard requirements refers to the specific set of criteria, also known as 'clauses', that are included within a standard that participants must demonstrate they are able to meet in full for a particular service to achieve certification.


When referring to a subcontractor for the purposes of the production of MarinTrust marine ingredients (such as fishmeal and fish oil) this relates to a third party or affiliate that is appointed under a contract or an agreement to carry out activities, services, or handle MarinTrust approved raw material and/or MarinTrust certified marine ingredients on behalf of the applicant or certified facility. This includes:

  • processors
  • packers 
  • encapsulators
  • transportation companies 
  • distribution companies 
  • storage facilities 

used to undertake part of the production or handling of marine ingredients including storage, transport, labelling, mixing, packaging.


Suspended is when a registered Certificate Body temporally make a certificate holder's certification invalid due to evidence that a certified location has failed to conform with any of the requirements as detailed in MarinTrust Certification Programme and the CB’s own “Rules Governing Certification”.

Suspended certificate holders are noted as 'suspended pending further investigation'.

Suspended certificates can be reinstated by the CB or fully withdrawn following the results of the investigation. 


Unit of Certification

The Unit of Certification (UoC) describes the particular product, service, location to which the certificate is applicable.

The UoC of MarinTrust Standard is the marine ingredient (such as fishmeal or fish oil) production facility. Production facilities must use raw materials (i.e. fish or by-products) sourced from approved MarinTrust fishery or by-products.

The UoC of the MarinTrust Chain of Custody Standard is facility involved in the processing/packaging, refining/storage/trading/blending activities of certified MarinTrust marine ingredients (such as fishmeal or fish oil). Facilities must use marine ingredients sourced from MarinTrust certified production facilities. 



Withdrawal refers to the process of a registered Certification Body fully revoking the validity of a certificate holder's certificate due to evidence that a certified location has failed to confirm with any requirements as detailed in the MarinTrust Certification Programme and or the CB’s own “Rules Governing Certification”. The withdrawal of certificate holder's certificate may take following the an investigation conducted as part of a suspension period or with immediate effect.

Witness Audit

Is the process in which a candidate auditor, who is in the process of becoming an approved auditor (either MarinTrust Standard or Chain of Custody Standard), is witnessed conducting an audit against the relevant standard by an approved MarinTrust auditor following a successful shadow audit.
