Aquaculture, or fish farming, has gained momentum as a viable method to produce seafood as demand for fresh fish has put a strain on natural populations.
It involves the breeding and harvesting of plants and animals in the water.
You'll need at least a bachelor's degree in biology or a related area for this type of job, and for high-level positions, an advanced degree may be required.
It was used by indigenous people of Australia and within the Roman Empire.
Aquaculture can take place in natural bodies of water such as ponds, lakes, marshland (which would be freshwater aquaculture) and the ocean (which is marine aquaculture).
It can also be conducted in man-made tanks, commonly found in fish hatcheries.
The addition of aquacultural stocks such as salmon and oysters into the marketplace has helped meet current seafood demands.
Aquaculture plays an important role in the economy, providing thousands of jobs in operations and ancillary services.
