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 ...

Saltwater aquaponics (also known as marine aquaponics) is a combination of plant cultivation and fish rearing (also called aquaculture), systems with similarities to standard aquaponics, except that it uses saltwater instead of the more commonly used freshwater. In some instances, this may be diluted saltwater.
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.
Currently, cobia are cultured in nurseries and grow-out offshore cages in many parts of Asia and off the coast of the United States, Mexico and Panama. In Taiwan cobia weighing 100–600 grams are cultured for 1–1.5 years to reach the 6–8 kilograms (13–18 lb) needed for export to Japan.
Extensive aquaculture has been practiced in Korea for several hundred years, with seaweed farming beginning in the 1600s, but modern intensive aquaculture (mainly for seaweed and shellfish) did not emerge until the 1960s. [5] [6] However, total annual aquaculture production was less than 100,000 tonnes in this period. Aquaculture production ...
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.
