In 2018, 1.5 million salmon are in the middle of a year-long trial at Ocean Farm 1 off the coast of Norway. The semi-submersible US$300 million project is the world's first deep-sea aquaculture project, and includes 61-meter (200 ft)-high by 91-meter (300 ft)-diameter pen made from a series of mesh-wire frames and nets.

A series of treatment processes is utilized to maintain water quality in intensive fish farming operations. These steps are often done in order or sometimes in tandem.
The southern bluefin tuna (Thunnus maccoyii) is a tuna of the family Scombridae found in open southern Hemisphere waters of all the world's oceans mainly between 30°S and 50°S, to nearly 60°S.

Marine shrimp farming is an aquaculture business for the cultivation of marine shrimp or prawns [Note 1] for human consumption. Although traditional shrimp farming has been carried out in Asia for centuries, large-scale commercial shrimp farming began in the 1970s, and production grew steeply, particularly to match the market demands of the United States, Japan and Western Europe.
The 2 tonnes (2.2 short tons; 2.0 long tons) so produced in 1975 was consumed entirely domestically, often sold directly to homemakers who prepared them for their families. [38] Swiss pisciculture production was then growing at an annual rate of 10 percent.
