The MSC is revising the Fisheries Certification Process to ensure the process for carrying out fishery assessments can be applied consistently and more efficiently.
These revisions are being carried out as part of the MSC’s Fisheries Program Revisions, to address issues arising from Version 3.1 of the Standard and the Fisheries Certification Process. This intends to ensure the MSC program continues to drive real and lasting progress towards ending overfishing.

Why are revisions needed?
The Fisheries Certification Process (FCP) defines the protocol that must be followed by Conformity Assessment Bodies and assessors during a fishery assessment and was last updated alongside the MSC Fisheries Standard Version 3.1. However, feedback identified aspects of the FCP that were unclear, and it was reported that fewer stakeholders were participating in assessments due to the complexity of the requirements and the additional time and resources needed.What revisions have been proposed?
Revisions have been proposed to improve the efficiency of assessments and ensure a clearer assessment process. These changes also aim to improve the cost-effectiveness of assessments and audits and improve the experience for all stakeholders engaging in the process.
Processes for scope extensions, splitting certificates and adding other eligible fishers to a certificate have been clarified, alongside clarifications to the definitions for Unit of Assessment and Unit of Certification.
Reporting templates for the fishery assessment and reassessment process have been streamlined. This intends to improve clarity, ensure consistency across, and improve the usability of reports and worksheets for assessors, fisheries, stakeholders, Peer Reviewers, and other users. A new Certification Statement template has also been developed, which will provide a consolidated source of key information on a certified fishery, such as units of certification, vessels, and the point at which the chain of custody starts. The template used by stakeholders to provide input into a fishery assessment has also been significantly improved to facilitate easier engagement.
Revisions have also been made to align the FCP and relevant reporting templates with relevant accreditation standards and related aspects of the MSC program, including the Chain of Custody Standard Review, Objections Process, and Labour eligibility requirements.
Key revisions and the rationale for change are described in each section below.

The harmonisation process is used by assessors to ensure overlapping fisheries (those targeting the same stocks, impacting the same species under Principle 2, or under the same management jurisdiction) receive consistent scores and conditions of certification. This requires the different assessors who carried out each assessment to work together and agree to harmonised scores for each overlapping fishery.
Proposed changes
Revisions have been developed to clarify how assessors should apply the harmonisation process, reduce complexity, and develop a more robust method for resolving disagreements on scoring.
The process has been clarified to explicitly define which aspects of the standard require harmonisation:
- Principle 1: harmonisation must be applied to most scoring issues, with defined exceptions.
- Principle 2: harmonisation must be used to ensure species and habitats are categorised consistently. It must also be used to ensure consistency when assessing impacts on non-target fish and invertebrate stocks, and whether the fishery is hindering recovery of endangered species. The revisions also clarify when scores produced using the Risk-Based Framework must be harmonised.
- Principle 3: it is now explicit which aspects must be harmonised. This includes
the requirement for determining whether the legal or customary framework in which the fishery operates is compatible with effective fisheries management. It also includes the requirement for determining whether mechanisms for monitoring, control and surveillance are in place and ensure compliance with management measures.
A new approach to resolving harmonisation disagreements has also been proposed. If assessors cannot agree on harmonised scores, three independent reviewers will be appointed by the MSC’s Peer Review College to adjudicate the disagreement and make a final decision.
This would replace the current approach, where the lowest score is used if assessors can’t reach agreement.
Improvements have also been made to the process to ensure clearer communication of timing and outcomes, while aiming to avoid additional burden and stakeholder fatigue.
Rationale
The proposals simplify the harmonisation process and make it easier and clearer to apply. This will ensure overlapping fisheries are assessed with greater consistency.
The new mechanism for reaching agreements on scores will also support a more efficient process, with an additional level of oversight provided by independent reviewers from the MSC Peer Review College.
The proposals aim to improve transparency by making the identification of overlapping Units of Assessment, the timing of harmonisation and the resulting decisions clearer to stakeholders, while avoiding unnecessary additional assessment work.
Overall, the revised approach is intended to achieve meaningful consistency between overlapping fisheries without requiring harmonisation where differences between fisheries can be demonstrated.
The revisions intend to make the harmonisation process easier to apply and to ensure more
consistent outcomes.
Proposed change
Revisions have been made to streamline the reassessment process. An Announcement Comment Draft Report (ACDR) will no longer be required at reassessment. Instead, assessors will be required to carry out a reassessment plan/change analysis detailing what has changed since the previous assessment.
Revisions have also been made to provide more structure to the reassessment timeline. This includes the addition of a fifth surveillance audit for fisheries that have open conditions after the fourth surveillance audit (which is currently the last opportunity for fisheries to demonstrate progress against conditions). This audit would be separate from the reassessment process and would not need to be completed within the reassessment deadline.
Rationale
The proposal to replace the ACDR with a reassessment plan intends to make the process more efficient by not duplicating information that already exists in other assessment reports, with a focus on what has changed and key areas for consideration during the reassessment.
The addition of the fifth surveillance audit aims to provide a clear process to ensure the ongoing surveillance of conditions with five-year deadlines, longer deadlines or conditions raised mid-certificate. This intends to better support fisheries in developing their plans to resolve conditions and provides additional opportunities for this progress to be verified.
Proposed change
Revisions have been made to how assessment teams set conditions of certification, establish deadlines for those conditions, and monitor progress.
This includes defining the circumstances in which assessors can set extended deadlines for resolving conditions. It has also been made explicit that an extension can only be given when the condition is first set. If an extended deadline is set, the decision and justification must be subject to review by independent experts who are part of the MSC’s Peer Review College.
Revisions have also been proposed that give fisheries more ownership over the actions and outputs needed to resolve their conditions. CABs will still be responsible for setting the verification deadlines and measuring progress annually.
Rationale
The changes proposed aim to improve transparency in the condition setting process and improve fisheries’ accountability for closing their conditions.
Defining the circumstances in which extended deadlines can be set will make assessments more consistent and provide greater transparency. The requirement for an extension to be subject to peer review also adds an additional level of oversight, ensuring the process remains credible.
Proposed change
The process for scoring fisheries against the requirements of the Fisheries Standard has been reorganised and simplified. This will make the scoring process easier to understand and to apply consistently.
Scores will continue to be determined in five-point increments, but assessors must now use a new scoring table to calculate the overall score for each performance indicator. Explicit definitions for scoring elements and where they apply have also been added to the Standard.
The new process replaces the more complex two-step approach to scoring that was previously used. This process will also apply when the Risk-Based Framework is used.
Rationale
The previous scoring process was considered unclear, and concerns were raised that it was being applied inconsistently. There was also a separate process for scoring data-limited fisheries using the Risk-based Framework. The new, simplified process provides
a clearer set of instructions which apply across all scheme documents. This intends to provide a more consistent and transparent approach across all fishery assessments.
Proposed change
Revisions have been made to further strengthen the integrity of MSC certified supply chains. This includes clarifying where responsibility transfers from fishery certification to Chain of Custody certification. The start of the chain of custody is now defined as the point at which catch is landed. However, assessors can still require the chain of custody to begin earlier if necessary.
A new template will also be introduced (the Fishery Certificate Template) to provide a consistent way for assessors to record traceability data.
Rationale
Clarifying the point of handover between the certified fishery and first stage in the chain of custody provides supply chain auditors with complete visibility over which products are eligible to enter the supply chain. This clarification, alongside the addition of the Fishery Certificate Template, will also ensure a standardised, transparent approach, and lead to more consistent outcomes.
Proposed change
Revisions will be made to clarify how assessors should consider inseparable catch (previously referred to as inseparable or practicably inseparable catch) and its entry into certified supply chains. Inseparable catch occurs when closely related species that look the same and are impossible to separate are caught.
The revisions include providing explicit eligibility criteria for those species which can enter a certified supply chain.
Inseparable catch that has been determined eligible must now be considered in the traceability section of the assessment report and the new Fishery Certificate Statement. New requirements also stipulate that assessors must continue to check eligibility at reassessment.
Rationale
The revisions intend to clarify that assessing inseparable species under Principle 1 is the default route for ensuring their eligibility to enter the supply chain as certified product.
Clarifying the circumstances in which species that have not been assessed under Principle 1 can be defined as inseparable and setting explicit eligibility criteria will provide greater transparency and control over which species enter certified supply chains.
The declaration of inseparable catch in the Fisheries Certificate Statement will also provide greater transparency, ensuring certified supply chain businesses have access to clear and consistent information.
Take part in our consultation
A 60-day public consultation on the proposed revisions is open until 8 December 2026.
All stakeholders and partners with an interest in the Fisheries Standard and assessment process can view the proposals and provide feedback through an online survey.
Attend our webinars
We will hold a series of webinars between 2 and 6 November 2026 to support participation in the consultation.
Each webinar will focus on a different set of revisions, providing a detailed explanation of the key revisions proposed and rationale for change. Attendees will also have an opportunity to ask questions during a live Q&A session.
There will be two webinars on the same topics held each day (07:00 – 08:00 UTC and 16:00 – 17:00 UTC).
Next steps
All feedback from the consultation will be analysed and used to refine the proposed revisions alongside findings from mock assessments, pilot tests and impact assessments.
A further 30-day consultation is expected to be held in April 2027.
The updated version of the Standard is expected be issued in September 2027 and come into effect six months after publication (early 2028).
