Indicator 2.12.3

by Contact on 8 October 2026

Requirement

The UoC shall not use feed containing protein derived from the same genus as the species being farmed. An exception applies where it can be demonstrated that same-species protein hydrolysates are verified to be <10,000 daltons, in which case use is allowed.

Evidence of Implementation

  • Records:

    • Feed purchased (including information on species/genus used as marine ingredients for fishmeal).

    • Feed fed.

Auditors Should Confirm

  • Records:

    • Feed purchased (including information on species/genus used as marine ingredients for fishmeal).

    • Feed fed.

Useful Resources

  • Although the science behind prion diseases, infectivity and pathogenicity in fish in association with Transmissible Spongiform Encephalopathies (TSEs) is not very well developed, ASC has taken a precautionary approach and followed the guidelines of FAO (2011) Aquaculture Development. 5. Use of Wild Fish as Feed in Aquaculture Principle 9.1 “For biosecurity reasons, intraspecies recycling is an unacceptable practice that should be prohibited”.

  • Protein hydrolysates verified to <10,000 daltons are allowed as controlling the molecular weight provides a good verification of the appropriateness of an applied transformation process. This is in line with Regulation (EU) 142/2011 regarding the use of animal by-products.
