Trolling is the name given to the type of fishing in which a natural or artificial bait, fitted with hooks, is towed from a line
attached to a moving boat. The appearance and motion of the bait is intended to excite carnivorous fish into attacking it, and
becoming hooked. This fishing method therefore aims to catch predatory fish, that is the types of fish which chase and eat other
fish.
Trolling is a fishing method which is carried out all over
the world, for commercial and recreational purposes. There
are many variations to the equipment and techniques used.
Trolling may be carried out at high speed, so that the
fisherman can cover a large fishing area, or slowly, so as to
avoid outrunning the fish. The lines may be of light, synthetic
material for invisibility, or may be of heavy wire and cable
for strength and resistance to cutting. The bait may be towed
at the surface, or may be trolled using weights or other
equipment to carry it down into deep water. The way in which
trolling is performed depends on local conditions, the species
sought, and their behaviour and physical characteristics.
There are, however, many tricks, tips and simple types of trolling equipment that are still known only to a small proportion
of troll fishermen. Some of these are recent innovations; others have been in use for years in certain areas but have never spread
further afield. In this book, we have tried to incorporate as many of these fishing tips as possible. We hope that all troll fishermen
will be able to find something new here, and use it to improve their fishing operations.
