According to the National Oceanic and
Atmospheric Administration, “Aquaculture -- also known as fish or shellfish
farming -- refers to the breeding, rearing, and harvesting of plants and
animals in all types of water environments.”
Aquaculture takes place under
controlled conditions and in a controlled environment therefore ensuring that
there are no pollutants in the water and also regulates the nutrients which
the organisms receive. These conditions allow harvesting of fish in moderation
in order to maintain a supply that can continue to reproduce.

Aquaculture practices can either be:
- Intensive- the cultivation of large amounts of fish which requires high quality feed and continuous maintenance.
- Extensive- this involves less maintenance as food is sometimes obtained naturally and the organisms reared are usually in smaller amounts.
