Fish farming is the principal form of aquaculture, while other methods may fall under mariculture.
It involves raising fish commercially in tanks or enclosures, usually for food.
A facility that releases juvenile fish into the wild for recreational fishing or to supplement a species' natural numbers is generally referred to as a fish hatchery.
Fish species raised by fish farms include salmon, catfish, tilapia, cod and others.
Basically, there are two kinds of aquaculture: extensive aquaculture based on local photosynthetical production and intensive aquaculture, in which the fishes are fed with external food supply.
