VIZ . 20 ft. As the See also:season advances, the See also:schools penetrate farther northwards into St See also:George's Channel or eastwards into the See also:English Channel. The See also:fishery then assumes proportions which render it next in importance to the See also:herring and See also:cod See also:fisheries. In See also:Plymouth alone a See also:fleet of some two See also:hundred boats assembles ; and on the See also:French See also:side of the Channel no less See also:capital and labour are invested in it, the vessels employed being, though less in number, larger in See also:size than on the English side. The See also:chief centre, however, of the fishery in the See also:west of See also:England is at See also:Newlyn, near See also:Penzance, where the small See also:local sailing boats are outnumbered by hundreds of large boats, both See also:sail and See also:steam, which come chiefly from See also:Lowestoft for the season. Simultaneously with the See also:drift-See also:net the deep-See also:sea-See also:seine and See also:shore-seine are used, which towards See also:June almost entirely supersede the drift-net. Towards the end of May the old See also:fish become heavy with spawn and are in the highest See also:condition for the table; and the latter See also:half of June or beginning of See also:July may be regarded as the See also:time at which the greater See also:part of See also:mackerel spawn. Considerable See also:numbers of mackerel are taken off See also:Norfolk and See also:Suffolk in May and June, and also in See also:September and See also:October. There can be no doubt that they enter the See also:North Sea from the English Channel, and return by the same route, but others travel See also:round the north of See also:Scotland and appear in rather small numbers off the See also:east See also:coast of that See also:country. On the See also:Norwegian coast mackerel fishing does not begin before May, whilst on the English coasts large catches are frequently made in See also: After the spawning the schools break up into smaller companies which are much scattered, and offer for two or three months employment to the See also:hand-See also:line fishermen. They now begin to disappear from the coasts and return to the open sea. Single individuals or small companies are found, however, on the coast all the See also:year round; they may have become detached from the See also:main bodies, and be seeking for the larger schools which have See also:long See also:left on their return See also:migration. Although, on the whole, the course and time of the See also:annual migration of mackerel are marked with See also:great regularity, their See also:appearance and abundance at certain localities are subject to great See also:variations. They may pass a spot at such a See also:depth as to evade the nets, and reappear at the See also:surface some days after farther eastwards; they may deviate from their See also:direct line of migration, and even temporarily return westwards. In some years between 1852 and 1867 the old mackerel disappeared off See also:Guernsey from the surface, and were accidentally discovered feeding at the bottom. Many were taken at to fathoms and deeper with the line, and all were of exceptionally large size, several measuring 18 in. and weighing nearly 3 lb; these are the largest mackerel on See also:record. The mackerel most esteemed as See also:food is the See also:common See also:species, and individuals from to to 12 in. in length are considered the best flavoured. In more See also:southern latitudes, however, this species seems to deteriorate, specimens from the coast of See also:Portugal, and from the Mediterranean and See also:Black Sea, being stated to be dry and resembling in flavour the See also:Spanish mackerel (S. colias), which is not esteemed for the table.
