Oyster farming is an aquaculture (or mariculture) practice in which oysters are bred and raised mainly for their pearls, shells and inner organ tissue, which is eaten. Oyster farming was practiced by the ancient Romans as early as the 1st century BC on the Italian peninsula [1] [2] and later in Britain for export to Rome. The French oyster ...
Oysters feed most actively at temperatures ranging from the high 60s to the high 70s (20–26 °C). [8] Under ideal laboratory conditions, an oyster can filter up to 190 L (50 US gal) of water per day. Under average conditions, mature oysters filter 11–45 L (3–12 U.S. gal).
Mariculture may consist of raising the organisms on or in artificial enclosures such as in floating netted enclosures for salmon, and on racks or in floating cages for oysters. In the case of enclosed salmon, they are fed by the operators; oysters on racks filter feed on naturally available food.

While Kumamoto oysters are native to Japan, Korea, Taiwan, and southern China, it was introduced to the West Coast of North America for commercial use in 1947. [5] It has not been established outside of its native range, and natural reproduction has not occurred due to its water temperature requirements, which are from 24–28 °C (75–82 °F).
The term oyster reef refers to dense aggregations of oysters that form large colonial communities. Because oyster larvae need to settle on hard substrates, new oyster reefs may form on stone or other hard marine debris. Eventually the oyster reef will propagate by spat settling on the shells of older or nonliving oysters. The dense aggregations ...

The optimum salinity for Pacific oysters is between 20 and 35 parts per thousand (ppt), and they can tolerate salinities as high as 38 ppt; at this level, however, reproduction is unlikely to occur. [10] The Pacific oyster is also a very temperature tolerant species, as it can withstand a range from −1.8 to 35 °C. [10]
