Requirement

The UoC shall ensure that the HMP includes acclimatisation measures to prevent sudden changes in water conditions affecting the health and welfare status of the crustaceans.

How Do I Interpret This Requirement?

  • Acclimatisation measures should be designed and maintained, e.g.:

    • Water temperature during transportation must be as close as possible to that which the crustaceans came from.

    • Crustaceans shall be released into a small area of the pond ‘hapa’ or net enclosures in the grow-out pond itself for a risk-assessed period to evaluate the capacity of the PL to adjust to the pond conditions.

Evidence of Implementation

  • acclimatisation measures and monitoring of the water quality according to HMP.

  • Records that confirm the monitoring of acclimatisation parameters before stocking.

  • Employees should demonstrate awareness of the acclimatisation measures and monitoring process above.

Auditors Should Confirm

  • The acclimatisation measures included in the HMP incorporate the minimum required elements and are implemented.

  • Implementation can be verified by cross-checking the process with relevant records, information from employee interviews and observations.
