Pilchard.
Although the common herring of our northern seas is beyond all doubt the most important of the tribe, yet there is no sea, no coast, where other species of the same family are not a source of abundance to man, and of astonishment by their vast numbers. Thus the enormous shoals of Pilchards appearing along our south-western coasts are not less valuable to the fishermen of Devon and Cornwall than the common herring to those of the North Sea. The older naturalists considered the pilchard, like the herring, as a visitor from a distant region, and they assigned to it also the same place of resort as that fish, with which indeed the pilchard has been sometimes confounded. To this it will be a sufficient reply, that the pilchard is never seen in the Northern Ocean. They frequent the French coasts, and are seen on those of Spain, but on neither in considerable numbers or with much regularity; so that few fishes confine themselves within such narrow bounds. On the coast of Cornwall they are found throughout all the seasons of the year, and even there their habits vary in the different months. In January they keep near the bottom, and are chiefly hauled up in the stomachs of ravenous fishes; in March they sometimes assemble in schulls, but this union is only partial and not permanent and only becomes so in July; when they regularly and permanently congregate so as to invite the fisherman's pursuit. The season and situation for spawning, and the choice of food, are the chief reasons which influence the motions of the great bodies of these fish; and it is probable that a thorough knowledge of these particulars would explain all the variations which have been noticed in the doings of the pilchard, in the numerous unsuccessful seasons of the fishery.
They feed with voracity on small crustaceous animals, and Mr. Yarrell frequently found their stomachs crammed with thousands of a minute species of shrimp, not larger than a flea. It is probably when they are in search of something like this, that fishermen report they have seen them lying in myriads quietly at the bottom, examining with their mouths the sand and small stones in shallow water. The abundance of this food must be enormous, to satisfy such a host.
"When near the coast," says the author of the "History of British Fishes," "the assemblage of pilchards assumes the arrangement of a mighty army, with its wings stretching parallel to the land, and the whole is composed of numberless smaller bodies, which are perpetually joining together, shifting their position, and separating again. There are three stations occupied by this great body, that have their separate influence on the success of the fishery. One is to the eastward of the Lizard, the most eastern extremity, reaching to the Bay of Bigbury in Devonshire, beyond which no fishing is carried on, except that it occasionally extends to Dartmouth; a second station is included between the Lizard and Land's End; and the third is on the north coast of the county, the chief station being about St. Ives. The subordinate motions of the shoals are much regulated by the tide, against the current of which they are rarely known to go, and the whole will sometimes remain parallel to the coast for several weeks, at the distance of a few leagues; and then, as if by general consent, they will advance close to the shore, sometimes without being discovered till they have reached it. This usually happens when the tides are strongest, and is the period when the principal opportunity is afforded for the prosecution of the sean-fishery." The quantity of pilchards taken is sometimes incredibly large. In 1847, a very productive year, 40,000 hogsheads were cured in Cornwall alone, representing probably, after all deductions, a net value to the takers of £80,000. The Sardine (Clupea sardina), a fish closely allied to the Pilchard though smaller, is considered as the most savoury of all the herring tribe. It is chiefly found in the Mediterranean, on the coasts of South France and Africa, and about the islands of Corsica and Sardinia, where it plays a no less important part than the Pilchard on the coasts of Cornwall and Devonshire.
Though a much less valuable fish than its larger-sized relatives, the diminutive Sprat is not to be despised. Coming into the market in immense quantities, and at a very moderate price, immediately after the herring season is over, it affords during all the winter months a cheap and agreeable food. Like all other species of the herring tribe, the sprats are capricious wanderers, and make their appearance in exceedingly variable numbers. The coasts of Kent, Essex, and Suffolk, are the most productive. So great is the supply thence obtained, that notwithstanding the immense quantity consumed by the vast population of London and its neighbourhood, there is yet occasionally a surplus to be disposed of at so low a price, as to induce the farmers, even so near the metropolis as Dartford, to use them for manure.
Anchovy.
The Mediterranean seems to be the peculiar birthplace of the Anchovy (Engraulis encrasicholus), where it appears in the spawning season in countless multitudes along the shallow coasts. It is about four inches long, of a bluish-brown colour on the back, and silvery-white on the belly. It is covered with large thin and easily deciduous scales, and may be readily distinguished from the Sprat and other kindred species by the anal fins being remarkably short. It is mostly caught in the neighbourhood of Antibes, Frejus, and St. Tropez, and sent pickled in enormous quantities to the fair of Beaucaire, from whence it is transported in small tin boxes to all parts of the world.
