Offshore aquaculture, also known as open water aquaculture or open ocean aquaculture, is an emerging approach to mariculture (seawater aquafarming) where fish farms are positioned in deeper and less sheltered waters some distance away from the coast, where the cultivated fish stocks are exposed to more naturalistic living conditions with ...
Mariculture, sometimes called marine farming or marine aquaculture, [1] is a branch of aquaculture involving the cultivation of marine organisms for food and other animal products, in seawater. Subsets of it include ( offshore mariculture ), fish farms built on littoral waters ( inshore mariculture ), or in artificial tanks , ponds or raceways ...
The aquaculture sector involves the collection of broodstock and production of fingerlings for grow out in sea cages, which are located in offshore and inshore waters. A specialist fleet of vessels performs feeding and harvesting operations at sea, with the most common working hours occurring between 4:00 am and 7:59 – 8:00 pm.
Activities directly conducted offshore, or whose products offshore, represented 2.67% of the GDP and 2,084,160 jobs.

Starting in the 1960s, the offshore waters, outside the then 12 nautical mile territorial sea, were exploited by Japanese, Taiwanese, South Korean, and Soviet trawlers. [8] In 1977 the 200 nautical mile exclusive economic zone was established. These zones were established because countries wanted protection from foreign fishing vessels.
Offshore cage systems could become a more environmentally sustainable method for commercial marine fish aquaculture. [15] However, some problems still exist in cobia culture, including high mortality due to stress during transfer from nursery tanks or inshore cages to the offshore grow-out cages, as well as disease.
Offshore construction – Installation of structures and facilities in a marine environment Mariculture – Cultivation of marine organisms in saltwater environments (specific Aquaculture – Farming of aquatic organisms) Offshore aquaculture – Fish farms in waters some distance away from the coast
Of that area, 7,713 ha is in established growing areas and is owned by the aquaculture industry, 4,010 ha is used to enhance the wild scallop fishery and belongs to the Challenger Scallop Enhancement Company, [6] and 2,465 ha is an exposed site six kilometres offshore from Napier where trials are being undertaken by a private company to test ...
