Consumption
Astacus astacus was once abundant in Europe, although it was expensive to buy, and is considered to be the finest edible crayfish. It is, however, susceptible to the crayfish plague carried by the invasive American species signal crayfish (Pacifastacus leniusculus), and is therefore listed as a vulnerable species on the IUCN Red List.
Documentation of the consumption of A. astacus dates back to the Middle Ages, when it was popular among the Swedish nobility, spreading to all social classes by the 17th and 18th centuries due to its ready availability. The crayfish are collected from the wild in traps, a practice which is being replaced by more intensive aquaculture of the signal crayfish in man-made ponds. The consumption of crayfish is an important part of traditional Scandinavian culture, including the crayfish party or kräftskiva, a feast to mark the end of summer.

Famous quotes containing the word consumption:
“There is held to be no surer test of civilisation than the increase per head of the consumption of alcohol and tobacco. Yet alcohol and tobacco are recognisable poisons, so that their consumption has only to be carried far enough to destroy civilisation altogether.”
—Havelock Ellis (1859–1939)
“Books constitute capital. A library book lasts as long as a house, for hundreds of years. It is not, then, an article of mere consumption but fairly of capital, and often in the case of professional men, setting out in life, it is their only capital.”
—Thomas Jefferson (1743–1826)
“What happens is that, as with drugs, he needs a stronger shot each time, and women are just women. The consumption of one woman is the consumption of all. You can’t double the dose.”
—Ian Fleming (1908–1964)
