This is extremely beneficial to the marine ecosystem because the oysters feed on particulate matter and nitrogen, often from anthropogenic sources. This, in turn, reduces the algae growth and leads to an overall cleaner marine environment. [26] [27] Other sources state that a single oyster can filter 24–96 liters a day (1–4 liters per hour ...
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).
Aquaculture (less commonly spelled aquiculture [1]), also known as aquafarming, is the controlled cultivation ("farming") of aquatic organisms such as fish, crustaceans, mollusks, algae and other organisms of value such as aquatic plants (e.g. lotus).

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]
On July 13, 1995, Chicago’s high temperature for the day reached 104 degrees during a notorious heat wave that killed more than 700 area residents.
Oyster reef restoration projects often place the sanitized shells of dead oysters, concrete, or limestone pieces on a soft bottom to encourage oyster spat settlement. [10] Restoration of intertidal eastern oyster reefs can match natural densities of oysters and mud crabs , and recover oyster stability in about 6 years. [ 18 ]
