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).
Ostrea edulis, commonly known as the European flat oyster, is a species of oyster native to Europe. In Great Britain and Ireland, localized names include Colchester native oyster , mud oyster , or edible oyster .
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 ...

The oysters attach to the underside of rocks or onto the shells of old oyster beds. Their habitats must have water depths of 0–71 meters, ranging in temperatures of 6-20 degrees Celsius, with a salinity above 25 ppt. However, the oysters can survive in areas with streams that cause a flux in the salinity.
The eastern oyster (Crassostrea virginica)—also called the Atlantic oyster, American oyster, or East Coast oyster—is a species of true oyster native to eastern North and South America. Other names in local or culinary use include the Wellfleet oyster , [ 3 ] Virginia oyster , Malpeque oyster , Blue Point oyster , Chesapeake Bay oyster , and ...
Drain the oysters, and if desired, strain and save the liquor for another use. (Transfer it to an airtight container and refrigerate for up to 3 days or freeze for up to 3 months.)
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]
