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.
