It is the principal form of aquaculture, while other methods may fall under mariculture. A facility that releases juvenile fishinto the wild for recreational fishing or to supplement a species' natural numbers is generally referred to as a fish hatchery. Worldwide, the most important fish species produced in fish farming are carp, tilapia, salmon, and catfish.
