Fish farmers are the general workers in the production of all types of fish and shellfish. Fish farms produce and rear fish mainly for sale to the food market, but some may be produced for angling or ornamental purposes. Fish farmers are responsible for rearing fish to a good size and health, increasing levels of production, whilst also retaining high ethical, sustainable and environmentally friendly standards.

There are many types of fish and shellfish that can be farmed for food, and each is farmed in a different habitat using a different method.

  • Freshwater fish like carp are farmed in freshwater tanks, ponds or enclosures
  • Seawater fish such as salmon, cod and haddock are farmed in large sea cages or pens, in farming units usually offshore
  • Shellfish are typically farmed in a natural marine habitat, such as on ropes or nets in the sea

Fish farmers will rear the fish after they are hatched, or will introduce young fish to the farm. They are responsible for feeding the fish, checking their health and preventing disease. Fish farmers require technical skills to maintain the habitat of the fish, keeping water at the correct temperature and pH balance and adding chemicals to keep the fish strong and healthy.

Fish farmers will grade the fish according to size and type, moving them into different enclosures where necessary and harvesting them when ready. Harvesting involves selecting the fish, killing them and preparing them for sale to fish mongers.

Other duties include maintaining the premises, containers and equipment to ensure that health and safety measures are met, and that fish are farmed ecologically. Sustainable fishing has a growing importance in consumer society, so fish farmers must take care to meet regulations.
