Indicator 4.1.3.15

Requirement

The UoC shall re-use cleaner fish where possible and under the following conditions: a) re-use shall only occur once; and b) re-use shall only occur within the site or the ABM (see Indicator 4.5.1); and c) re-use shall only occur if the outcome of a health assessment indicates low risk of disease transfer. The health assessment shall: – consider the health status of the salmon and the cleaner fish at the origin and destination sites; and – be conducted no longer than two weeks before re-use; and d) be approved by a registered veterinarian or an aquatic animal health professional; and cleaner fish are segregated from the salmon before transfer to the destination site.

How Do I Interpret This Requirement?

  • Prior to the end of the salmon production cycle, discuss with the veterinarian or animal health professional to decide if the cleaner fish are to be re-used or killed.

    • This will depend on:

      • If there are suitable sites for re-use within the same site or ABM (see Indicator 4.5.1).

      • The disease history of the cleaner fish.

      • The disease history of the salmon.

  • Whether the cleaner fish can be re-used within two weeks from being separated from the original salmon companions.

    • The approval by the registered veterinarian or animal health professional.

Evidence of Implementation

  • Records:

    • The original source of cleaner fish.

    • The date of the addition of the cleaner fish.

    • The date of the end of the salmon production cycle.

    • The approval by the registered veterinarian or animal health professional.

Auditors Should Confirm

  • The approval process by reviewing records and cross-checking dates or stocking, disease history, end of salmon production as well as approval records for re-use.

Indicator 4.1.2.32

Requirement

The UoC shall segregate cleaner fish in advance of any salmonid-specific treatments and ensure they are retained under appropriate conditions.
