For developing a site-specific predator control within the HMP, the UoC should consider:

The site-specific characteristics required to be assessed by Indicator 4.2.1.8.e) predator control measures specific to the type of handling, e.g.:

Predator control measures specific to the type of handling operations.

Verification of mortalities associated with predators during handling operations.

The HMP includes the required considerations above.

Employees are:

Trained on predator control verifications, e.g.:

For developing a site-specific biosecurity mechanism within the HMP, the UoC should consider:

Biosecurity measures related to the type of handling, e.g.:

For developing a site-specific biosecurity during handling the HMP includes the considerations for:

The HMP includes the required minimum considerations above.

Employees are:

Visual inspection after handling should be included in the HMP.

The monitoring process, that incorporates the corrective actions required, included in the HMP.

Records that confirm the monitoring of the morphology and behaviour at the feeding trays. A checked box on the monitoring records indicating whether monitoring morphology and behaviour took place or not is accepted.

Employees should demonstrate awareness of the established behavioural monitoring process.

The monitoring process included in the HMP that incorporates corrective actions and is implemented.

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

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

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.

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.

Draining the pond completely helps in eliminating unwanted organisms and disease.

Areas that cannot be completely drained should be treated with disinfectants to kill any pathogens, e.g.:

Removing any dead or living animals helps in preventing disease spread and decay, which can affect the water quality and the health of future pond crops, e.g.:

Remove any organic debris such as leaves, branches and sludge. If the pond water is too acidic, agricultural lime (calcium carbonate) may be added to neutralise the pH, making the environment more suitable for crustacean e.g.:

Records confirming the monitoring of the required parameters for pond preparation and their conformance with acceptable quality levels included in the HMP prior to stocking.

Record of drying period.

Record of addition of lime if applied.

The water quality monitoring process, that incorporates the minimum elements required for pond preparation.

Employees should demonstrate awareness of the established water quality monitoring process during handling.

Pond preparation process, that incorporates the minimum elements required, included in the indicator and cross-checking with the handling operations present in the HMP.

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

Examples of considerations of external conditions:

Avoid transferring post-larvae during periods where there are less than favourable conditions:

HMP includes consideration for external conditions necessary to perform handling.

Records:

HMP includes considerations for external conditions for handling and are implemented.

Implementation can be confirmed by cross-checking the HMP with records, information from employee interviews and observations.

The contingency plans should consider:

Effective corrective measures, e.g.:

HMP includes processes’ contingency plans.

Records:

The HMP includes considerations on crustacean health and welfare before handling events, including considerations for the existence of a backup system.

Presence of a backup system.

Records:

Scope applicable to Penaeus vannamei and Penaeus monodon species.

Transition periods span from May 2025 to May 2031, with staged percentages for AF broodstock compliance (see Appendix 12 table 4).

The objective is to ensure a gradual shift toward using only ablation-free female broodstock, aligning with improved welfare practices.

The monitoring process involves developing and implementing a tracking system to monitor the origin of stock (nauplii, larvae or PL).

Where feasible, conduct physical audits or site visits of hatcheries to verify by visual inspection compliance with AF broodstock sourcing.

Hatcheries supplying the stock should provide clear documentation of the broodstock’s status (AF or non-AF).

Maintain records of sourcing, including certificates or declarations from hatcheries confirming broodstock compliance with AF requirements.

Maintain detailed production logs showing the percentage of stock derived from AF broodstock at each transition phase.

Employees involved in sourcing should demonstrate understanding to comply with the requirement to ensure they can explain the sourcing process to verify compliance during audits.

The monitoring process to confirm that the UoC has a documented system to track and verify the origin of nauplii, larvae, or PL.

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