Trolling is a method of fishing where one or more fishing lines, baited with lures or bait fish, are drawn through the water at a consistent, low speed. This may be behind a moving boat, or by slowly winding the line in when fishing from a static position, or even sweeping the line from side-to-side, e.g. when fishing from a jetty. Trolling is used to catch pelagic fish such as salmon, mackerel and kingfish.
In American English, trolling can be phonetically confused with trawling, a different method of fishing where a net (trawl) is drawn through the water instead of lines. Trolling is used both for recreational and commercial fishing whereas trawling is used mainly for commercial fishing.
Trolling from a moving boat involves moving quite slowly through the water. This can be accomplished with the use of a special trolling motor. Multiple lines are often used, and outriggers can be used to spread the lines more widely and reduce their chances of tangling. Downriggers can also be used to keep the lures or baits trailing at a desired depth.
Outriggers are poles which allow a boat to troll several lines in the water without tangling. A boat which trolls enough lines can simulate a school of fish. [1] [2] [3]
Downrigger are devices used while trolling to keep a bait or lure at the desired depth. In practice, fish swim at different depths according to factors such as the temperature and amount of light in the water, and the speed and direction of water currents. [4] A downrigger consists of a one or two metre horizontal pole which supports a weight, typically about 3 kg (6.6 lb) of lead, on a steel cable. A clip called a "line release" attaches the fishing line to the weight, and the bait or lure is attached to the release. The fishing line is reeled in by a spool powered either by manual cranking or by an electric motor. [5] Using a downrigger can be hazardous. For example, man-made reservoirs can contain submerged trees and other structures beneath the surface which downriggers can snag.[ citation needed ]
"Paravanes" (underwater kites) are sometimes used as depth controlling devices, [6] particularly in commercial tuna fishing operations. These kites have various shapes, such as arrowhead paravanes, flexi-wing paravanes, and bi-wing paravanes. [7] The devices can place the lure or bait at designated depths and positions; and in this way multiple devices can be towed at the same time without the devices and bait interfering with each other. [8]
"Spreaders" allow multiple baited hooks or lures to be trolled from a single line. There are many inventive spreader designs, such as devices which cause the baited hooks or lures to move in helical patterns, in a sophisticated emulation of the schooling behaviour of a group of fish. [9]
"Planer boards" are trolled devices designed to spread fishing lures out away from the fishing vessel. They allow multiple lines to be trolled. They come in dual board and inline board designs. Dual board designs consist of two boards that are spaced apart and attached by a line to a mast near the front of the boat with a separate fishing line in a spring tension release clip that separates when the fishing line is set. Inline boards are attached directly to the fishing line and a spring tension clip that releases upon setting or tripping the planer board so it slides down the fishing line to a swivel tied several feet in front of the lure. Inlines are popular with walleye and wahoo [10] fishermen. Once tripped they offer much less resistance when reeling in a fish. [11] [12] [13]

To be effective, trolling baits and lures must have the visual ability to attract fish and intrigue them with the way they move through the water. [14] Most trolling lures are designed to look and behave like dying, injured, or fast moving fish. They include:
Trolling baits and lures are either tied with a knot, such as the improved clinch knot, or connected with a tiny safety pin-like device called a "snap" onto the fishing line which is in turn connected to the reel. The reel is attached to a rod. The motion is of the lure is made by winding line back on to the reel, by sweeping the fishing rod, jigging movements with the fishing rod, or by trolling behind a moving boat. Lures can be contrasted with artificial flies, commonly called flies by fly fishers, which either float on the water surface, slowly sink or float underwater, in imitation some form of insect fish food. However some flies, such as the trolling tandem streamer fly, are designed for trolling behind a moving boat.
As an example, marlin lures are typically 7–14 in (18–36 cm) or more long with a shaped plastic or metal head and a plastic skirt. The design of the lure head, particularly its face, gives the lure its individual action when trolled through the water. Lure actions range from an active side-to-side swimming pattern to pushing water aggressively on the surface to, most commonly, tracking along in a straight line with a regular surface pop and bubble trail. Besides the shape, weight and size of the lure head, the length and thickness of skirting, the number and size of hooks and the length and size of the leader used in lure rigging all influence the action of the lure: how actively it will run and how it will respond to different sea conditions. Experienced anglers fine tune their lures to get the action they want. Specialized lures made specifically for trolling swordfish use plastic glow sticks.
A pattern of four or more lures can be trolled at varying distances behind the boat. Lures may be fished either straight from the rod tip ("flat lines"), or from outriggers.
In addition to attaching a lure to the fishing line, an oval piece of metal (often hammered or curved for reflective purposes) called a dodger is often used to attract fish from greater distances. Lures designed for trolling with downriggers include metal "spoons" that are often decorated with colour tape, and plastic or rubber "squids" with various colours.
A daisy chain is a chain of plastic lures which have no hooks. Their purpose is to function as teasers which attract a school of fish closer to the lures that do have hooks. [16]
Baits and lures are typically trolled at speeds up to 9 knots (17 km/h), though speeds up to 15 knots (28 km/h) can be used, particularly when boats are travelling to different fishing areas. The speed at which the lure is pulled through the water impacts on the fishing success. The optimum trolling speed varies with different species of fish, with weather conditions and the time of year, and other conditions. Chinook salmon can be successfully trolled at higher speeds than more docile lake trout. For these reasons fishermen use devices that accurately track speed. [4] Trolling motors calibrate speed more accurately than large outboard motors. Trolling plates are also used with larger motors to slow the boat to the desired speed, although some anglers experience mixed results with plates.[ citation needed ]
Trolling can be effective at surprisingly low speeds. Kayaks fitted with a deck-mounted bracket for holding a rod can be paddled to troll effectively for salmon. [18]
In marine environments, trolling is used in big-game fishing to catch large offshore or open-water species such as tuna and marlin. Saltwater anglers also troll for inshore species such as bluefish, kingfish and various jacks. [19]
Rock fishermen can use an umbrella rig as a method of trolling without using a boat. Typically, an umbrella rig consists of four plastic neon green lures with a lead dragging behind. An additional lure is attached to the lead. Only the lure behind the lead need have hooks attached because this lure can appear to a stalking fish as a wounded or sick laggard in a school, making it a more likely target. [20]
A pattern of multiple baits or lures can be trolled at varying distances behind a boat. Lures can be fished straight from the rod tip (flat line), or from outriggers. Purpose designed sinkers exist to control the trolling depth on freshwater lakes. [21]
Freshwater anglers can also find trolling effective. Recreational fishermen can successfully troll lakes and reservoirs for salmon and trout. It can be the method of choice for catching the elusive muskie, and a useful technique for catching walleye, black bass and striped bass. [19] For light and medium freshwater gamefishing, any reasonably robust casting or spinning rod can be used as a trolling rod. Effective trolling rods should be fairly stiff with a relatively fast action, since "whippy" slow action rods are frustrating to troll with.[ citation needed ]
Commercial trolling vessels catch fish by towing astern one or more trolling lines. The trolling lines are fishing lines with natural or artificial baited hooks trailed by a vessel near the surface or at a certain depth. Several lines can be towed at the same time using outriggers to keep the lines apart. The lines can be hauled in manually or by small winches. A length of rubber is often included in each line as a shock absorber. The trolling line is towed at a speed depending on the target species, from 2.3 knots up to at least 7 knots. Trollers range from small open boats to large refrigerated vessels 30 meters long. In many tropical artisanal fisheries, trolling is done with sailing canoes with outriggers for stability. With properly designed vessels, trolling is an economical and efficient way of catching tuna, mackerel and other pelagic fish swimming close to the surface. Purpose-built trollers are usually equipped with two or four trolling booms raised and lowered by topping lifts, held in position by adjustable stays. Electrically powered or hydraulic reels can be used to haul in the lines. [22] [23]
Commercial trolling for tuna is more successful near offshore banks than in open water areas, and is also enhanced in the vicinity of a fish aggregation device (FAD). [24]
Historically, in Alaska, hand hook and line trolling were used commercially to catch king and silver salmon in salt water. This method required minimal gear-boat, lines and hooks—and was used to catch fish that were still feeding in open water before returning to spawn. Trolling was very successful in southeast Alaska and historically the catch was used by the fresh and mild-cured fish packing industries. Power boats located near feeding grounds conducted most of the trolling. Each boat had four to ten lines, extending from tall poles hung outboard when fishing; each line carried several hooks, with heavy lead sinkers and spoons or baits as lures. Trolling lengthened the fishing season, allowing fishermen to fish in early spring before spawning runs. [25] [26]
Fishing is the activity of trying to catch fish. Fish are often caught as wildlife from the natural environment, but may also be caught from stocked bodies of water such as ponds, canals, park wetlands and reservoirs. Fishing techniques include hand-gathering, spearing, netting, angling, shooting and trapping, as well as more destructive and often illegal techniques such as electrocution, blasting and poisoning.
A fishing rod is a long, thin rod used by anglers to catch fish by manipulating a line ending in a hook. At its most basic form, a fishing rod is a straight rigid stick/pole with a line attached to one end ; however, modern rods are usually elastic and generally have the line stored in a reel mounted at the rod handle, which is hand-cranked and controls the line retrieval, as well as numerous line-restricting rings that distribute bending stress along the rod and help dampening down/prevent line whipping and entanglement. To better entice fish, baits or lures are dressed onto the one or more hooks attached to the line, and a bite indicator is used, some of which might be incorporated as part of the rod itself.
A fishing reel is a hand-cranked reel used in angling to wind and stow fishing line, typically mounted onto a fishing rod, but may also be used on compound bows or crossbows to retrieve tethered arrows when bowfishing.
A fishing line is any flexible, high-tensile cord used in angling to tether and pull in fish, in conjunction with at least one hook. Fishing lines are usually pulled by and stored in a reel, but can also be retrieved by hand, with a fixed attachment to the end of a rod, or via a motorized trolling outrigger.
Fly fishing is an angling technique that uses an ultra-lightweight lure called an artificial fly, which typically mimics small invertebrates such as flying and aquatic insects to attract and catch fish. Because the mass of the fly lure is insufficient to overcome air resistance, it cannot be launched far using conventional gears and techniques, so specialized tackles are used instead and the casting techniques are significantly different from other forms of angling. It is also very common for the angler to wear waders, carry a hand net, and stand in the water when fishing.
Angling is a fishing technique that uses a fish hook attached to a fishing line to tether individual fish in the mouth. The fishing line is usually manipulated via a fishing rod, although rodless techniques such as handlining also exist. Modern angling rods are usually fitted with a fishing reel that functions as a cranking device for storing, retrieving and releasing out the line, although Tenkara fishing and traditional cane pole fishing are two rod-angling methods that do not use any reel. The fish hook itself can be additionally weighted with a denser tackle called a sinker, and is typically dressed with an appetizing bait to attract and entice the fish into swallowing the hook, but sometimes an inedible fake/imitation bait with multiple attached hooks is used instead of a single hook with edible bait. Some type of bite indicator, such as a float, a bell or a quiver tip, is often used to relay underwater status of the hook to the surface and alert the angler of a fish's presence.
Big-game fishing, also known as offshore sportfishing, offshore gamefishing or blue-water fishing, is a form of recreational fishing targeting large game fish, usually on a large body of water such as a sea or ocean.
A fishing lure is any one of a broad category of artificial angling baits that are inedible replicas designed to mimic prey animals that attract the attention of predatory fish, typically via appearances, flashy colors, bright reflections, movements, vibrations and/or loud noises which appeal to the fish's predation instinct and entice it into gulping the lure. Angling activities using lures are known as lure fishing.
A downrigger is a device used while fishing using the trolling method, which places a lure at the desired depth. A downrigger consists of a three to six-foot horizontal pole which supports a cannonball, generally 10 to 15 pounds, by a steel cable. A clip, also known as a "release," attaches a fishing line to the cannonball weight. The bait or lure is attached to the release.
Marlin fishing or billfishing is offshore saltwater game fishing targeting several species of fast-swimming pelagic predatory fish with elongated rostrum collectively known as billfish, which include those from the families Istiophoridae and Xiphiidae (swordfish). It is considered by some fishermen to be a pinnacle of big-game fishing, due to the size, speed and power of the billfish and their relative elusiveness.
A spinnerbait or spinner is any one of a family of hybrid fishing lures that combines the designs of a swimbait with one or more spoon lure blades. Spinnerbaits get the name from the action of the metallic blades, which passively revolve around the attachment point like a spinning propeller when the lure is in motion, creating varying degrees of vibration and flashing that mimic small fish or other preys of interest to large predatory fishes. The two most popular types of spinnerbaits are the in-line spinner and safety pin spinnerbait, though others such as the tail spinner also exist. Spinnerbaits are used principally for catching freshwater fishes such as perch, pike and bass.
Fishing tackle is the equipment used by anglers when fishing. Almost any equipment or gear used in fishing can be called fishing tackle, examples being hooks, lines, baits/lures, rods, reels, floats, sinkers/feeders, nets, spears, gaffs and traps, as well as wires, snaps, beads, spoons, blades, spinners, clevises and tools that make it easy to tie knots.
Coarse fishing is a phrase commonly used in Britain and Ireland. It refers to the angling for rough fish, which are fish species considered undesirable as food or game fish. Freshwater game fish are all salmonids, particularly salmon, trout and char. Generally, coarse fish are freshwater fish that are not salmonids, though there is often disagreement over whether grayling should be classified as a game fish or a coarse fish.
A fishing vessel is a boat or ship used to catch fish and other valuable nektonic aquatic animals in the sea, lake or river. Humans have used different kinds of surface vessels in commercial, artisanal and recreational fishing.
Fishing techniques are methods for catching fish. The term may also be applied to methods for catching other aquatic animals such as molluscs and edible marine invertebrates.
Recreational fishermen usually fish either from a boat or from a shoreline or river bank. When fishing from a boat, or fishing vessel, most fishing techniques can be used, from nets to fish traps, but some form of angling is by far the most common. Compared to fishing from the land, fishing from a boat allows more access to different fishing grounds and different species of fish.
The paravane is a towed winged (hydrofoiled) underwater object—a water kite. Paravanes have been used in sport or commercial fishing, marine exploration and industry, sports and military applications. The wings of paravanes are sometimes in a fixed position, else positioned remotely or by actions of a human pilot. Pioneer parafoil developer Domina Jalbert considered water kites hardly different from air kites. However, paravanes generally orient themselves in respect to the water surface. They may have sensors that record or transmit data or are used entirely for generating a holding force like a sea anchor does. While a sea-anchor allows a vessel to drift more slowly downwind, the paravane travels sideways at several times the downwind speed. Paravanes are, like air kites, often symmetrical in one axis and travel in two directions, the change being effected by gybing, shunting, or flipping over.

The following outline is provided as an overview of and topical guide to fishing:
Kite fishing is a fishing technique. It involves a kite from which a drop line hangs, attached to a lure or bait. The kite is flown over the surface of a body of water, and the bait floats near the waterline until taken by a fish. The kite then drops immediately, signaling to the fisherman that the bait has been taken, and the fish can then be hauled in. Kites can provide boatless fishermen access to waters that would otherwise be available only to boats. Similarly, for boat owners, kites provide a way to fish in areas where it is not safe to navigate - such as shallows or coral reef.
