Requirement

Indicator applicability: species with an EICAT Category MR/MV The UoC shall calculate the number of known escapes per production cycle or year, whichever is stricter, following the method outlined in Appendix 6 (6.1). The UoC shall not exceed a maximum number of known escapes per production cycle or year, whichever is stricter, of the following: a. marine salmonids: 300 individuals b. other fish species: 6% If the maximum number of known escapes is exceeded, the UoC shall, by the next working day: c. submit a formal notification to the CAB for cancellation of certification; and d. notify ASC of the exceedance of known escapes, according to ASC data submission procedures.

How Do I Interpret This Requirement?

  • [Note]: Indicator 2.4.11 only applies for species/regions that are classified as ‘Category Major/Massive (MR/MV)’ in the EICAT Species Factsheet.

  • This Indicator requires a strict limit on the number of known escapes allowed per production cycle or per year, whichever threshold is stricter. ‘Known escapes’ refers to escape incidents that are either observed directly or detected through monitoring. It does not include unverified or speculative losses.

  • Escape limits:

    • Marine salmonids (e.g., Atlantic salmon, trout): A hard limit of 300 individuals per production cycle. The formula for calculation can be found in Appendix 6 (6.1).

    • Other fish species: A percentage-based limit of 6% of the total stocked population per production cycle or year (whichever is stricter). The formula for calculation can be found in Appendix 6 (6.1).

    • If the UoC exceeds the set limit, a formal notification to the CAB shall be submitted by the next working day.

Evidence of Implementation

  • The UoC has a register of known escapes in which exceedance of the set limit is monitored.

Auditors Should Confirm

  • Records of known escapes are maintained.

  • Escape limits are to remain below the set threshold and that calculations are made correctly.
