No licensing, legislative, regulatory or certification requirements apply to this unit at the time of publication.

Application of the Unit

Application of the unit 

The unit has application to cultured or held stock  in holding, display, hatchery, nursery or grow out facilities.

The unit applies to personnel who have technical responsibilities for stock production and for improving production outcomes.

Feeding, health management, handling, harvesting and post-harvest activities are covered by other aquaculture specialist units.

Skills in supervising staff are covered by AHCWRK403A Supervise work routines and staff performance.

All enterprise or workplace procedures and activities are carried out according to relevant government regulations , licensing and other compliance requirements , including occupational health and safety  (OHS ) guidelines , food safety and hygiene regulations and procedures , and ecologically sustainable development  (ESD ) principles .

Elements and Performance Criteria Pre-Content

Elements describe the essential outcomes of a unit of competency.

Performance criteria describe the performance needed to demonstrate achievement of the element. Where bold italicised text is used, further information is detailed in the required skills and knowledge section and the range statement. Assessment of performance is to be consistent with the evidence guide.

Elements and Performance Criteria



1. Implement and monitor stock production plan

1.1. Production plan , policies and procedures are conveyed to staff for implementation.

1.2. Feed supplies are assessed against production plan and feeding schedule.

1.3. Distribution schedules are monitored and stocking rates varied, as required.

1.4. Stock growth or production is monitored using an appropriate performance recording system and harvesting is undertaken to meet marketing goals.

1.5. Stock health is monitored and any pest, parasite or disease outbreaks quickly controlled with samples being sent to relevant authorities, where required.

1.6. Effects of feeds and health treatments on stock are monitored and actions taken to avoid or minimise stock health problems and negative effects on product quality.

1.7. Options for mechanisation or automation of process or activity are assessed, including the use of specialised contract services.

1.8. Progress of production plan is reviewed regularly with staff.

2. Continually review and improve production performance

2.1. Physical and operations records  are maintained for analysis and evaluation of production performance and for management of the business.

2.2. Evaluation of production performance at each stage or component of enterprise is undertaken to determine sustainability and profitability and for use in reviewing and revising production plans.

2.3. Information  on innovations related to existing or potential enterprises and facility activities are obtained and assessed to determine their relevance and possible application.

2.4. Relevant innovations are tested to determine their suitability and adaptability to individual circumstances, their benefit/cost assessed, and outcomes reported to the management teams.

2.5. Management team is kept informed of production schedule and performance.
