Sardine

Sardine is a member of the herring family and an important food fish. The word «sardine» refers to several groups of fishes. But it is used mainly for such species as the Pacific sardine, the South African sardine, and the European sardine, or pilchard. Other members of the herring family, including sprats and young Atlantic herring, are also sold as sardines.

The name «sardine» was given to the fish because they were first caught near Sardinia, an Italian island in the Mediterranean Sea.

Sardines live in warm ocean waters near the shores of almost all the continents. They are especially plentiful on the coasts of Japan, north-western Africa, and western South America. Sardines average 23 to 30 centimeters in length and about 115 grams in weight. The upper part of their body is blush-grey, and the lower part is silvery. Adult sardines usually swim in large shoals. They feed on small animal and life called plankton.

Most sardine fishing takes place on moonless nights. The movement of sardines disturbs tiny organisms that live near the surface of the sea.

It causes these organisms to produce light by means of a chemical reaction. This light called bioluminescence reveals the presence of sardine schools. Most sardines are caught with a special type of net called a purse seine.

The annual sardine catch worldwide totals about II million tons. Peru is the world's leading sardine-fishing nation, followed by Chile and Japan,

Cans of sardines are a familiar sight on supermarket shelves. Canneries precook sardines and remove part of their natural oil and moisture. Industry uses sardine oil in such products as linoleum, paint and varnish. Some sardines are made into fish meal, which is used in animal feed and fertilizer. Small sardines are used as bait in commercial tuna fishing.
