All you need to know about Oysters

Oysters are bivalve molluscs that are eaten in various cultures around the globe. There are some oysters that create pearls but they are not edible. They are furry from the outside and belong to a different family of oysters called ‘Ostreidae’. The other family of oysters is ‘Pteriidae’, they are edible and are considered as a delicacy. This family of Oysters is also known as “true oysters”.

The edible component is the meat inside the oyster; you just have to crack the outer shell and cook the meat in any way you desire. This article is going to give you a detailed description of what oysters are, their habitat, shells, behavior, and survival.


Although it may be possible that some eatable oysters produce pearls sometimes but this happens very rarely. This aspect should not be confused with the actual pearl oysters. True oysters are found throughout the world’s ocean. However, you can mostly find them in shallow sea waters and colonies, often referred to as beds or reefs. The Atlantic waters from Canada to Argentina are the most heavily harvested and popular areas to find oysters. Another type is also found in the Pacific sea from Japan to Washington State till the borders of Australia.


The shape of the oyster shells mostly depends on where they are attached to. They are mostly found in oval or pear-shaped. Oyster shells are whitish grey in color from the outside but from the inside, they are porcelain white in color.


Oysters mostly consume algae and other food particles from water that is constantly drawing over their gills. They change gender more than once in their life and often reproduce when the water warms up by hatching.

Threats to Survival

Over the years, the number of oysters being caught has greatly decreased. Due to this reason, it has become a luxury treat. Although some commercial harvesting is also done; however, oysters are extremely sensitive to water quality and coastal pollution. They also have the ability to retain toxins in the meat inside them which makes it unsafe for human consumption.

How do oysters survive?

Oysters live and grow in water but the surprising fact is that it can live up to two weeks without water. When they are moved outside water, their metabolism slows down. Those oysters that are not very strong need to be consumed within a day or two. Oyster shells are very good at protecting themselves. They have strong muscles that close their shells whenever they feel threatened.

Oysters come in all forms, some can be eaten and some cannot. From over the years, oyster production has greatly declined due to water pollution and oil spills in the sea. It is our responsibility to take care of this unique species and make our sea waters clean enough for them to survive.

The History of Oysters

Oysters are saltwater bivalve molluscs that live in blackish habitats in the sea waters. They have an average lifespan of up to 20 years; however, outside water, they can live up to 2 days only. The average size of an oyster is 3 to 14 inches.

There are some species of oysters that are very hard while some are very irregular in shape. There are some oysters that produce special kind of pearls. These kinds of oysters are harvested in a special kind of environment in the seabeds to harvest the pearls. There are also other types of oysters which are edible oysters. They are different in specie from the ones that produce pearls.

History of Oysters

The history of oysters dates back to the time of Aristotle. They were first discovered by Aristotle from river banks near an Island called Lesbos. These oysters were then transplanted in another less populated area called Chios.

Oysters are cultured for more than a century now. They are set to mature themselves naturally or they are spread out on previously made oyster grounds on seabeds.

Today, many people use the same technique for gardening oysters as did their forefather in China, Japan, Greece, and Rome. The following is an account of major areas in the world where oysters were discovered and used.


One roman entrepreneurial devised a method by setting a net of twings around adult oysters to catch the small oysters whenever they were reproduced. He then moved the twings to another area for growing the oysters in spa locations in Rome.


In Japan, people used bamboos with leaves still attached. They also invented lantern nets that helped them to easily separate the oysters by size.


The Chinese however invented the most interesting thing. They developed an ear hanging for oysters and scallops which worked by punching a small hole in live oyster shell and then stringing them in a chain.


The French used a cement to attach baby oysters to wooden racks.

These were some of the methods used by the ancient people that are now gradually refined and expanded with time.

Oyster Harvesting Today

These days, commercial growers of oysters produce baby oysters in indoor hatcheries, which contain the right kind of conditions for adult oysters to produce the eggs. China is the greatest contributor in farmed sea food. It owns about 70% of the world’s global fish farming, including majority of oyster production.

The most sophisticated processes are raising their oysters in large metal racks that have a mechanical action to create the environment and stimulation of rough sea. Other methods include introducing a warmer temperature so that the hatching process can be accelerated.

Some other factors such as climate change and pollutants in the sea can greatly affect the breeding process. Due to these factors, the oyster shells are not fully formed, which make it harder for baby oysters to build their calcium carbonate rich shells.
