Recirculating Aquaculture Systems (RAS)

Certification of aquatic products from open and semi-closed systems such as sea-cages, ponds or flow-through systems was the initial focus of the ASC standards. In recent years, however, the number of recirculating aquaculture systems (RAS) has significantly increased. This is why ASC is now developing a RAS module to adapt the ASC standards to ensure that the main impacts from RAS are assessed.

RAS Module – Public Consultation

Following a 30-day public consultation (August 3 – September 4, 2020), the intent is that this RAS Module – considered an interim solution – becomes operational as soon as possible (January 2021) and until the aligned ASC Farm Standard, which will include RAS specific indicators, becomes effective.

The RAS module summarises the key environmental and social impacts associated with RAS and addresses these impacts using existing indicators from the ASC’s species-specific standards. This ensures auditability. To become certified, RAS farms will need to comply to the relevant species-specific standards and the additional list of indicators covered in the RAS module. These indicators cover:

  • Water resource use,
  • Water discharge,
  • Waste disposal,
  • Energy use.

The collection of this data will also be used in the Alignment Project and to help better inform decisions.

The ASC sought feedback on the proposed RAS Module, and notably aspect regarding auditability and applicability. Suggestions for any additional considerations which should be included in RAS assessments were also welcome.
