MSC is progressing a draft MSC Mass Balance CoC Standard which will provide chain of custody requirements for marine ingredients handled by feed mills certified against the Aquaculture Stewardship Council’s (ASC) Feed Standard (ASC-FS).

Eventually all ASC certified aquaculture farms must use ASC compliant feed. The ASC-FS aims to incentivise feed mills to source more responsible raw materials over time, partly by requiring incremental increased volumes of marine ingredients sourced from MSC (or equivalent) certified fisheries. The ASC-FS will require certified feed mills to meet the MSC Mass Balance CoC Standard for physical mixing of certified and non-certified marine ingredients.

Mass Balance for ASC Responsible Feed

ASC is developing an ASC Responsible Feed Standard to reduce the environmental and social impacts created by the production of ingredients used for aquaculture feed. Feed for aquaculture often contains significant percentages of fishmeal and fish oil, in addition to other land-based ingredients such as grains. ASC and MSC are encouraging the wild fishmeal and fish oil content of feed for ASC certified farms to be sourced sustainably

Feed mills (the unit of certification in the ASC Feed Standard) are not yet able to segregate aquaculture feed ingredients following the current MSC CoC Standard based on segregation.

The development of the MSC Mass Balance CoC Standard aims to support the following objectives:

  • To provide the basis for business-to-business claims for feed mills meeting the requirements for traceability of marine ingredients;
  • To broaden the MSC CoC offering to increase accessibility of the program for use in different sectors.
  • To support the engagement of global reduction fisheries in the MSC program by providing incentive to become certified or improve towards future certification.
