Fish hatcheries are industrial farm units where the eggs of fish are incubated, stored and hatched, before the grown fish are released into the wild or sold to fisheries. Hatcheries can be a department of large fish farms, or can be run independently, supplying newly hatched fish to fisheries. Fisheries technicians are needed to check the conditions of the un-hatched eggs, the water and the state of the equipment, increasing the levels of productivity in the fishery.

Fisheries technicians can either be involved in freshwater or marine farming and hatchery management and research. They have a variety of tasks in the workplace, depending on the size and type of the farming unit, and their level of experience.

Typical tasks could include:

  • Breeding and raising stock from fertilised fish eggs
  • Keeping records of data
  • Monitoring water conditions and temperature
  • Identifying and treating disease or infection
  • Monitoring the condition of eggs
  • Using oxygen meters, salinity meters, pH (acidity) meters
  • Feeding fish
  • Caring for juvenile fish once hatched
  • Preparing stock for transport

Fisheries technicians need to enjoy working around water. They need to demonstrate interest in aquaculture and fishing and will ideally have fishing experience. Technicians need to have good communication skills for working as a team and the ability to follow instructions methodically.

Fish hatcheries are highly technical workplaces with a lot of equipment and machinery. As well as being able to correctly operate the equipment, technicians will be needed to follow health and safety guidelines in the workplace and may need to maintain security on the premises. Technicians should work to ensure healthy, sustainable and profitable fish farms.
