"Fish farming is a form of aquaculture in which

fish are raised in enclosures to be sold as food.

It is the fastest-growing area of animal food production.

Today, about half the fish consumed globally are raised

in these artificial environments. Commonly farmed species

include salmon, tuna, cod, trout, and halibut.

These “aquafarms” can take the form of mesh cages

submerged in natural bodies of water or concrete enclosures on land.
