Oysters are a very popular dish in the world as well as in Vietnam. They are nutritious, healthy seafood and are loved by many people. But few people know that this dish was very cheap before, it can be said that no one took it. But now, oysters are a dish showing luxury and class, only for the rich.
Oysters are molluscs belonging to the group of bivalve molluscs in the family of clams and small shellfish that live on the coast, coastal cliffs or estuaries. They often live on other substrates such as rock reefs or bridge foundations. Oysters eat plankton and organisms in the mud, sand, and seawater. Oysters play an important role in the ecosystem because they filter impurities from the water and are a source of food for coastal communities.
Most of the world's wild oysters are found in five locations in North America. Oysters have been on the earth for a long time. This shellfish is estimated to have been around for about 300 million years, and humans have used them as food for centuries. About 200 years ago, this shellfish was extremely cheap and could be used as free food for everyone.
However, oyster farming began to be developed by Sergius Orata, a Roman engineer famous for his invention of underfloor heating, and since its inception and spread, oyster farming has become a thriving business. Although you may have seen oysters on the menu more often in recent times, their popularity now is nothing compared to just 200 years ago.
The oyster trade boomed in the early 19th century, and the animals are sold as street food throughout London, Paris and New York as they remain a super cheap and easy snack. reach out to a wide range of people. In 1860, a small English seaside town of Winstead shipped 50 million tons of oysters to London each year, and by 1900, New York was consuming 1 million oysters a day.
But as popularity grew, so did the problems associated with this dish. Industrialization and dredging in the UK has led to overfishing, and as more people move to the coast, more and more wastewater is dumped into oyster waters. Soon, epidemics of typhoid and other diseases appeared, and many oyster businesses had to close. Severe winters and new diseases killed off many of the surviving native oysters, giving the species a bad reputation that would last for years to come. Another reason for the drop in oyster prices in the early 20th century: child labor.
In the early 20th century, American photographer Lewis Hine captured images of many children working in the oyster industry, even photographing a 4-year-old baby named Mary who had to shave two pots of oysters every day. . Everything had to change. Everyone in the world soon realized the importance of clean water in oyster farming and did not allow the use of child labor.
Of course, making oysters environmentally safe and legal and ethical also comes at a cost, as shellfish take a lot of work to produce. Therefore, the price of oysters has increased rapidly, ranging from 36 - 54 USD/12 children (from about 850,000 VND to 1.25 million VND). Some oyster species are more expensive, for example Sydney oysters cost up to 198 USD / 6 (more than 4.5 million VND).
Oysters may only have a nine-day shelf life, but that doesn't stop them from being shipped globally. And with its popularity and image as a luxury food, the demand for this animal will never stop growing. This means that the oyster species is declining rapidly. Oysters become expensive not only because of their declining numbers, the health benefits also make the value of oysters increase.
