Fish farms

Fish farming is the principal form of aquaculture, while other methods may fall under mariculture. Fish farming 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.

There is an increasing demand for fish and fish protein in the Union, which has resulted in widespread overfishing in wild fisheries. Fish farming offers fish marketers another source.

Originally, farming carnivorous fish, such as salmon, did not always reduce pressure on wild fisheries, since carnivorous farmed fish were usually fed fishmeal and fish oil extracted from wild forage fish. As the use of fish farms increased, commercial fish farms started raising forage fish to feed those raised for sale.

Not counting corporate owned waterworlds, the fish farms on New Sweden are among the most extensive ones within Union space.
