The practice of raising fish or water plants for food is known as aquaculture. A shrimp farmer works in the aquaculture industry.
The word aquaculture combines the Latin aqua-, "water," with culture, also from a Latin root, meaning "agriculture" or "a cultivating." Originally, this term referred only to fish farming. Today, you can also practice aquaculture by growing seaweed and algae, or raising shellfish like oysters and scallops. Today, aquaculture provides about half of all the fish and shellfish eaten by humans.
