Modifications to the MSC certification requirements for enhanced bivalve fisheries


In July 2011 a workshop was held at the MSC offices in London to discuss improving the current MSC scoring methodology to better accommodate the unique attributes of enhanced bivalve fisheries. Lead auditors and assessment team members participated in the workshop and shared their experiences in assessing enhanced bivalve fisheries against the MSC standard.

A draft set of modifications to the certification requirements along with a decision tree for assessing enhanced Catch and Grow (CAG) type bivalve fisheries were created as a result of the workshop. These were further developed by the MSC and its Technical Advisory Board to the form presented in this consultation.


The objective of this consultation was to receive stakeholder views on modifications to the MSC certification requirements to:

  1. standardise the way enhanced bivalve fisheries are evaluated and,
  2. clarify the outstanding issues with regard to translocations, genetic impacts and habitat/ecosystem interactions.  

Results of the consultation

Comments were received by a range of stakeholders, who were generally supportive of the need to provide specific guidance and PISGs for enhanced bivalve fisheries.  Stakeholders were also supportive of the effort to make the MSC assessment process simpler and more accessible for these types of fisheries. Concerns about the elimination of certain PIs within the default tree were expressed by some stakeholders. MSC provides specific rationales for the changes made and responded via email to consultees on comments received.

The proposed changes were reviewed after the consultation and approved by the MSC's Technical Advisory Board (TAB).   A new  version of the MSC Certification Requirements is available for download here. For more information in this policy issue please see Recent Policy Changes

The new Requirements and Guidance were issued to certifiers 10 January 2012 and will become effective on 10 March 2012.

Next steps

Certifiers can begin using new requirements as of January 10th.
