knowledge

sector-specific

Fish grading is an essential knowledge of the following occupations:

Water-based aquaculture technician: Water-based aquaculture technicians coordinate and supervise activities on fattening aquaculture organisms in suspended systems (floating or submerged structures). They participate in extraction operations and handling organisms for commercialisation. Water-based aquaculture technicians supervise maintenance of equipment and facilities (cages, rafts, longlines, bouchot).
Aquaculture cage technician: Aquaculture cage technicians operate in the production of aquatic organisms in water-based (freshwater, brackish water, salt water) on-growing processes in cages.
Aquaculture harvesting manager: Aquaculture harvesting managers control harvesting operations of aquatic organisms which entails understanding and knowledge of techniques and equipment used in harvesting processes.
Aquaculture production manager: Aquaculture production managers plan, direct and coordinate the production of fish, shellfish or other forms of aquatic life such as cash crops, in large-scale aquaculture operations to culture and harvest or for release into fresh, brackish or salt water. 

Aquaculture recirculation manager: Aquaculture recirculation managers control the production of aquatic organisms in land-based recirculation systems, manage water re-use processes and supervise complex circulation, aeration and biofilter systems.
Aquaculture husbandry manager: Aquaculture husbandry managers specialise in the husbandry of ongrowing aquatic species, especially in the feeding, growth, and stock management processes.
Aquaculture husbandry technician: Aquaculture husbandry technicians operate in aquatic organisms’ production, specialising in the husbandry of ongrowing culture processes, especially in feeding and stock management.

Fish grading is optional for these occupations. This means knowing this knowledge may be an asset for career advancement if you are in one of these occupations.

Aquaculture cage mooring worker: Aquaculture cage mooring workers operate highly-specialised equipment in order to moor cages in stable stations, drifting cages or even self-propelled and semi-submerged cages.
