Fish identification and classification is an essential knowledge of the following occupations:

Aquaculture hatchery manager: Aquaculture hatchery managers plan, direct, and coordinate the production in large-scale aquaculture operations to breed fish and shellfish, developing aquaculture breeding strategies using various types of spawning techniques. They control the reproduction and the early life cycle stages of cultured species. They supervise incubation, early feeding and rearing techniques of the cultured species.
Fish and seafood specialised seller: Fish and seafood specialised sellers sell fish, crustaceans and molluscs in specialised shops.
 
Fisheries adviser: Fisheries advisers provide consultancy on fish stocks and their habitats. They manage the costal fishing business modernisation and provide improvement solutions. Fisheries advisers develop plans and policies for fisheries management. They may provide advice on protected farms and wild fish stock.
Fish and seafood shop manager: Fish and seafood shop managers assume responsibility for activities and staff in specialised shops.
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 rearing technician: Aquaculture rearing technicians operate in aquatic organisms’ production. They are specialists in the rearing, weaning and production of juveniles.
Aquatic animal health professional: Aquatic animal health professionals diagnose, prevent and treat diseases, injuries and dysfunctions of aquatic animals by implementing appropriate sampling protocols. They supervise the use of medicines, including vaccines, and collect data on fish health, making regular reports to the appropriate personnel. They may provide care to a wide range of aquatic animals or specialise  in the treatment of a particular group or in a particular speciality area. They may provide advice, support and training to farm staff on best practice with regard to the health and welfare of the cultured organisms.
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 site supervisor: Aquaculture site supervisors supervise production processes in large-scale aquaculture operations and inspect aquaculture sites to maintain and improve performance. They maintain the health, safety and security of the workplace, develop management plans to reduce the risks from pests, predators and diseases and supervise both the disposal of bio and chemical waste and the maintenance of equipment and machinery.
Aquaculture harvesting technician: Aquaculture harvesting technicians operate the harvesting process of aquatic organisms’ production, managing the complex equipment and machinery used in the harvesting of specific cultured species.

Fish identification and classification 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.

Water quality analyst: Water quality analysts safeguard the quality of water through scientific analysis, ensuring quality and safety standards are met. They take samples of the water and perform laboratory tests, and develop purification procedures so it can serve as drinking water, for irrigation purposes, and other water supply purposes.
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. 
Specialised seller: Specialised sellers sell goods in specialised shops.
Hydrologist: Hydrologists research and study the quality, current challenges, and distribution of water in the Earth. They study water supply from rivers, streams, and springs to determine their adequate and sustainable use. Together with a cross functional team of professionals, they plan and develop how water can be supplied to cities and urban areas while ensuring efficiency and resource conservation.
Aquaculture biologist: Aquaculture biologists apply knowledge gained from research about aquatic animals and plant life and their interactions with each other and the environment, in order to improve aquaculture production, prevent animal health and environmental problems and to provide solutions if necessary.

Water-based aquaculture worker: Water-based aquaculture workers carry out manual activities in the ongrowing processes of cultured aquatic organisms in water-based suspended systems (floating or submerged structures). They participate in extraction operations and the handling of organisms for commercialisation. Water-based aquaculture workers maintain and clean facilities (nets, mooring ropes, cages)..
Aquaculture mooring manager: Aquaculture mooring managers carry out and supervise the mooring of cages in stable stations, drifting cages or even self-propelled and semi-submerged cages. They safely operate and moor a variety of different types of large-scale cages, manage conditions such as currents, wave climate and seabed profile, in open or semi-open water areas.
Biologist: Biologists study living organisms and life in its broader extent in combination with its environment. Through research, they strive to explain the functional mechanisms, interactions, and evolution of organisms.
Aquaculture harvesting worker: Aquaculture harvesting workers work in the harvesting of those aquatic organisms cultured in land-based on-growing processes.
