Elements and Performance Criteria

1. Plan operation and maintenance of a recirculating aquaculture system
   • Confirm operations, maintenance or design or upgrade specifications in the culture or holding system or facility with senior personnel
   • Draw up work plans or schedules, order materials and arrange labour and appropriate equipment according to specifications and in consultation with senior personnel
   • Check raw and prefabricated materials against delivery manifest or specifications
   • Prepare worksite according to specifications, and secure for safety or loss prevention
   • Assess potential risks, including environmental and water quality parameters for the cultured or held stock, and prepare contingency plans
   • Brief staff members on work objectives relevant to the site, equipment being used and type of maintenance or upgrade activities
   • Quantify costs and confirm budget with senior personnel
2. Implement operations, maintenance or upgrade program
   • Implement work plan to minimise disruption to workplace operations and stress to cultured or held stock
   • Monitor progress of maintenance or upgrade program against the work plan, and adjust for unforeseen circumstances
   • Confirm availability of required materials, resource and supply provisions, and labour
   • Anticipate, avoid or minimise hazards and environmental implications and other potential problems through contingency planning
3. Monitor operations, maintenance or upgrade activities
   • Monitor operations, maintenance or upgrade activities and component or system performances against maintenance or upgrade plan
   • Monitor costs within workplace budget requirements
   • Give feedback to staff members on work progress and performance
   • Prepare records or reports to management on project progress
   • Check and ensure that the maintained or upgraded system or facility fits maintenance or design specifications, is operable and complies with biosecurity regulatory requirements
   • Check budget for operations, maintenance or upgrade, and report major discrepancies to senior personnel
4. Finalise and review operations, maintenance and upgrade activities
   • Supervise clean-up of work area, including repairs and storage of equipment
   • Record relevant operations, maintenance and upgrade data, observations or information, and check any abnormal records
   • Prepare required reports for senior personnel
