Next the pike must be ousted from trout-streams. Special nets have been invented by which pike can be routed from their strongholds. Much hunting about quickens the intelligence of the pike to such a degree that he cannot be secured in the ordinary manner; he baffles the net by keeping close to the bank, behind stones, or by retiring to holes under roots. Perch have to go as well as pike; and then comes the turn of birds.

Herons, kingfishers, moorhens, coots, grebes, ducks, teal, various divers, are all proscribed on behalf o£ trout. Herons are regarded as most injurious to a fishery. As was observed a century ago, a single heron will soon empty a pond or a stretch of brook. As their longnecks give them easy command of a wide radius in spying round them, it is rather difficult to shoot them with a shot-gun; but with the small-bore rifles now made no heron is safe. They are generally shot early in the morning. Were it not for the fact that herons nest like rooks, and that heronries are valued appurtenances in parks, they would soon become scarce. Kingfishers prey on smaller fish, but are believed to eat almost as many as herons. Kingfishers resort in numbers to trout nurseries, which are as traps for them: and there they are more than decimated. Owls are known to take fish occasionally, and are therefore shot. The greatest loss sustained in fisheries takes place in the spawning season, and again when the fry are about. Some students of fish-life believe that almost all
