OYSTERS IN GENERAL

OYSTERS HAVE EXISTED SINCE PRE-HISTORIC TIMES.

The saxons enjoyed them before the Romans invaded Britain and there are those that would say it was for their excellent oysters that they invaded at all! Throughout their history, oysters have been regarded as a luxury but due to over-fishing the price dropped so low that at the beginning of the 19th Century they became the food of the poor. During the famine years people who lived near the sea survived on them. In about 1850, oyster culture started to become an industry and legislation in France and Britain protected the stocks.

OYSTERS FARMING

OYSTER FARMING IS A SKILLED BUSINESS INVOLVING FOUR SEPARATE STAGES:

  • Collecting larvae (captage du naissain)
  • Raising (l’elevage)
  • Fattening (l’affinage)
  • Preparation for market (l’expedition)

Like other forms of farming oysters are affected by the weather, pollution and disease but unlike farming on land you cannot treat your livestock against sickness nor can you put it into a warm barn if the winter gets too cold! It takes 3-5 years for oysters to grow to a diameter of 3″ – a marketable oyster during which time the producers risk is very high. This is one of the reasons why the cost to the consumer has risen so much over the past few years. For the technically minded, their nutritional value is: Water – 79.5%, Fat – 1.8%, Protein – 10.5%, Carbohydrate – 5.6%, Ash, sand salt – 2.47%. Vitamins – A, B1, B2, C, D, PP. Each oyster contains about 7 calories which should allow the most weight conscious among us to enjoy half a dozen or so. Oysters are considered to be an aphrodisiac. Casanova is said to have eaten them every day! While there is no evidence to uphold this theory, they certainly are a healthy food.
