Elements and Performance Criteria

1. Plan for the operation of a recirculating aquaculture system
   • Interpret and confirm operations and routine maintenance work plan or schedule with supervisor
   • Confirm labour and equipment or technology requirements with supervisor
   • Identify workplace requirements for optimal ranges for basic environmental parameters, advanced environmental parameters and water quality parameters affecting cultured or held stock
   • Confer with team members on basic operations and routine maintenance according to work plan or schedule
   • Confirm contingency plans and relay to team members
2. Optimise system operations
   • Identify appropriate components for operations, including personal protective equipment
   • Perform pre-operational checks and calibrations
   • Monitor culture conditions and operation of components, and adjust to optimise conditions
   • Alter operation or production schedule as required to compensate for factors affecting cultured or held stock during operations
3. Monitor maintenance schedule
   • Confirm maintenance schedule with team members
   • Monitor repairs and maintenance for pre-operation, standard operation and post-operation according to maintenance schedule
   • Arrange repair or replacement of worn or damaged components
   • Check and confirm optimal operation of components following maintenance
4. Finalise operation, monitoring and maintenance activities
   • Check cleaning of work area and disposal of waste materials are completed according to workplace procedures and environmental requirements
   • Check condition, maintenance requirements and storage of tools and equipment
   • Record relevant data and observations, and report any abnormal records to supervisor

Performance Evidence
