It is a pretty sight, these little silvery Herrings playing in the shallow water. Millions of them dart about and flash in the sunshine, during the summer months, round our coasts. Sea-birds and other enemies hover round, to feast on the tiny fish. Great numbers of these baby Herrings are caught and sold as "Whitebait." The older Herrings, having laid their eggs, leave the shallows, and make their way into deep water. They are no longer nice to eat, and the Herring harvest is over until the following season. In our talk on flat-fish we shall notice how they are caught, near the bed of the sea, in the _trawl-net_. Now this net is of no use for the capture of Herrings. They swim in the open water, near the surface, and so another kind of trap, the _drift-net_, is used. Hundreds of vessels sail from our fishing ports when King Herring is about. Each vessel carries a number of drift-nets. These nets are to be let down like a hanging wall, in the path of the shoal, at night. Corks or bladders are fastened to the upper edge of the nets. Of course they are all mended and made ready before the vessels reach the fishing grounds. It is not easy to know where to shoot the nets; all the skill and knowledge of the fisherman are needed to locate the shoals, and, without this knowledge, he would come home with an empty vessel. Even as it is, he sometimes catches no more fish than would fill his hat. A sharp look-out is kept. An oily gleam in the sea tells the knowing fisherman that the shoal is there; or he may see a Gull swoop down and carry off a Herring. Then the nets are put out in the path of the shoal. A big fleet of fishing vessels may let down a thousand miles of nets! The Herrings, not seeing the fine wall of net, swim into it. Now the openings in the net--the meshes--are one inch across, just wide enough for the Herring to poke his head through. Once through, he is caught. His gill-covers prevent him from drawing back again. Thousands of other Herrings are held tight, all around him, and the rest of the shoal scatters for the time being. When the nets are hauled in, the fisherman beholds a mighty catch, a sight to repay him for all his trouble. On being taken from its watery home each Herring is dead almost at once--"as dead as a Herring." Then comes the race to the market. Once in port, the vessels are rapidly emptied. Hundreds of thousands of shining, silvery bodies are piled on the quays--a sight worth seeing! An army of packers gets to work; and the fresh fish are soon on the rail, speeding to the great fish markets, on the way to your breakfast table. The story of the Herring fishery is one of deep interest, and of great importance. Millions of Herrings are caught every year, forming a cheap and good food. Yet there are uncountable numbers left; and there is not the least danger that our nets can ever empty the sea of this wonderful little fish.
