Elements and Performance Criteria

1. Breed and raise progeny
   • Monitor signs of imminent spawning and control environment to ensure successful spawning
   • Collect spawn according to workplace procedures
   • Assess the quality of eggs and sperm and undertake fertilisation of the eggs, if appropriate
   • Apply post-spawning broodstock husbandry techniques as required
   • Hatch fertilised eggs and care for progeny according to workplace procedures
   • Monitor and document water quality, stock behaviour and environmental parameters
2. Prepare for hatchery production
   • Interpret and confirm hatchery requirements with supervisor
   • Confirm labour and equipment requirements with supervisor
   • Identify risk factors that could affect the quality of the end cultured or held stock progeny, and plan to minimise risk
   • Communicate with team members on hatchery production operations
3. Collect and care for broodstock
   • Provide clean, functional conditions for all stock according to workplace procedures and hygiene requirements
   • Ensure selected broodstock are maintained in their selected structure or system with minimal stress
   • Condition broodstock to induce maturation or breeding and spawning behaviour
   • Ensure identified broodstock to be spawned are maintained in an optimal condition prior to spawning
   • Monitor and maintain water quality requirements of broodstock according to workplace procedures
4. Breed and raiseprogenyprogeny
   • Monitor signs of imminent spawning and control environment to ensure successful spawning
   • Collect spawn according to workplace procedures
   • Assess the quality of eggs and sperm and undertake fertilisation of the eggs, if appropriate
   • Apply post-spawning broodstock husbandry techniques as required
   • Hatch fertilised eggs and care for progeny according to workplace procedures
   • Monitor water quality, stock behaviour and environmental parameters and identify and document changing conditions
5. Harvest and distribute progeny
   • Select progeny through quality assessment with supervisor, and harvest progeny
   • Grade, sort and transport progeny to new on-farm culture or holding structures
   • Note, harvest and pack order requirements for external transport
6. Complete breeding activities
   • Check cleaning of work area and disposal of waste materials are completed according to workplace procedures and environmental requirements
   • Check condition and storage of tools and equipment, and forward repair requirements to supervisor
   • Record relevant data and observations and report any abnormal records to supervisor

Performance Evidence

An individual demonstrating competency must satisfy all of the elements and performance criteria in this unit.

There must be evidence that the individual has, on at least one occasion, monitored hatchery operations in the collection and care of broodstock, breeding and raising of progeny and preparation of stock for distribution, including:

confirming hatchery requirements with supervisor and team members

applying risk assessment processes and putting controls in place to mitigate risk and minimise impact

applying safe and efficient handling of animals throughout their lifecycle

monitoring and recording water quality and environmental parameters during all growing cycles

applying workplace quality standards when harvesting progeny for distribution

maintaining a hygienic and functional work area during and after hatchery operations

maintaining accurate records on hatchery operations

identifying changing environmental conditions.
