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.
Fishing lines generally resemble a long, ultra-thin rope, with important attributes including length, thickness, material and build. Other factors relevant to certain fishing practice include breaking strength, knot strength, UV resistance, castability, limpness, stretch, memory, abrasion resistance and visibility. Traditional fishing lines are made of silk, while most modern lines are made from synthetic polymers such as nylon, polyethylene or polyvinylidene fluoride ("fluorocarbon") [1] [2] and may come in monofilament or braided (multifilament) forms.
Fishing with a hook-and-line setup is called angling. Fish are caught when one are drawn by the bait/lure dressed on the hook into swallowing it in whole, causing in the hook (usually barbed) piercing the soft tissues and anchoring into the mouthparts, gullet or gill, resulting in the fish becoming firmly tethered to the line. Another more primitive method is to use a straight gorge, which is buried longitudinally in the bait such that it would be swallowed end first, and the tension along the line would fix it cross-wise in the fish's stomach or gullet and so the capture would be assured. Once the fish is hooked, the line can then pull it towards the angler and eventually fetch it out of the water (known as "landing" the fish). Heavier fish can be difficult to retrieve by only dragging the line (as it might overwhelm and snap the line) and might need to be landed via additionally using a hand net (a.k.a. landing net) or a hooked pole called a gaff.
Trolling is a technique where one or more lines, each with at least one hooked fishing lure at the end, is dragged through the water, which mimick schooling forage fish. Trolling from a moving boat is used in both big-game and commercial fishing as a method of catching large open-water species such as tuna and marlin (which are instinctively drawn to schoolers), and can also be used when angling in freshwater as a way to catch salmon, northern pike, muskellunge and walleye. The technique allows anglers to cover a large body of water in a short time without having to cast and retrieve lures constantly.
Longline fishing and trotlining are commercial fishing technique that uses many secondary lines with baited hooks hanging perpendicularly from a single main line.
Snagging is a fishing technique where a large, sharp grappling hook is used to pierce the fish externally in the body instead of inside the fish's mouth, and is therefore not the same as angling. Generally, a large open-gaped treble hook with a heavy sinker is cast into a river containing a large amount of fish (such as salmon) and is quickly jerked and reeled in, which gives the snag hook a gaff-like "clawing" motion that can spear its sharp points past the scales and skin and deep into the body. Modern technologies such as underwater cameras are sometimes used to help improve the timing of snagging. Due to the mutilating nature of this technique (where the fish are typically too deeply injured to be released alive), snagging is frequently deemed an unethical and illegal method, and some snagging practitioners have added procedures to disguise the snagging practice, such as adding baits or jerking the line using a fishing rod, to make it look like angling.
Traditionally, only a single thread of line is used to connect the hook with the rod and reel. However, most modern angling setups use at least two sections of line (typically the mainline and the leader) joined with a bend knot (such as the famously named fisherman's knot). Occasionally a swivel might be used to join the lines and reduce the bait/lure spinning due to the inherent line twisting from a fixed-spool reel.
A typical modern angling setup can include the following line sections:
Leonard Mascall, in his book from 1596 titled "A Booke of fishing with Hooke and Line, and of all other instruments thereunto belonging". followed in many ways after Dame Juliana Berners, has an excerpt establishing silk worms in the area of England at that time:
..."In May, take the stone flye or Caddis worme, and the bobbe worme vnder the Cowtorde: also ye may take the silke worme, and the baite that breedeth on a Fearne leafe." ...
And another excerpt explaining compiling a silk leader-line for a catgut fly-line.
"...whippe it so faire as yee shall see good, then next your hooke at the bought put throw your silke or haire in going round about the hooke three times, then plucke first your silke or haire..."
So back then there was silk and horse hair used for angling.
As written in 1667 by Samuel Pepys, the fishing lines in his time were made from catgut. [3] Later, silk fishing lines were used around 1724. [4]
Modern fishing lines intended for spinning, spin cast, or bait casting reels are almost entirely made from artificial substances, including nylon (typically 610 or 612), polyvinylidene fluoride (PVDF, also called fluorocarbon), polyethylene, Dacron and UHMWPE (Honeywell's Spectra or Dyneema). The most common type is monofilament , made of a single strand. Fishermen often use monofilament because of its buoyant characteristics and its ability to stretch under load. The line stretch has advantages, such as damping the force when setting the hook and when fighting strong fish. On very far distances the damping may become a disadvantage. Recently, other alternatives to standard nylon monofilament lines have been introduced made of copolymers or fluorocarbon, or a combination of the two materials. Fluorocarbon fishing line is made of the fluoropolymer PVDF and it is valued for its refractive index, which is similar to that of water, making it less visible to fish. Fluorocarbon is also a denser material, and therefore, is not nearly as buoyant as monofilament. Anglers often utilize fluorocarbon when they need their baits to stay closer to the bottom without the use of heavy sinkers. There are also braided fishing lines, cofilament and thermally fused lines, also known as "superlines" for their small diameter, lack of stretch, and great strength relative to standard nylon monofilament lines. Braided, thermally fused, and chemically fused varieties of "superlines" are now readily available.
Fly lines consist of a tough braided or monofilament core, wrapped in a thick waterproof plastic sheath, often of polyvinyl chloride (PVC). In the case of floating fly lines, the PVC sheath is usually embedded with many "microballoons", or air bubbles, and may also be impregnated with silicone or other lubricants to give buoyancy and reduce wear. In order to fill up the reel spool and ensure an adequate reserve in case of a run by a powerful fish, fly lines are usually attached to a secondary line at the butt section, called backing. Fly line backing is usually composed of braided dacron or gelspun monofilaments. All fly lines are equipped with a leader of monofilament or fluorocarbon fishing line, usually (but not always) tapered in diameter, and referred to by the "X-size" (0X, 2X, 4X, etc.) of its final tip section, or tippet. Tippet size is usually between 0X and 8X, where 0X is the thickest diameter, and 8X is the thinnest. There are exceptions to this, and tippet sizes do exist outside of the 0X–8X parameter. [5]
Tenkara lines are special lines used for the fixed-line fishing method of tenkara. Traditionally these are furled lines the same length as the tenkara rod. Although original to Japan, these lines are similar to the British tradition of furled leader. They consist of several strands being twisted together in decreasing numbers toward the tip of the line, thus creating a taper that allows the line to cast the fly. It serves the same purpose as the fly-line, to propel a fly forward. They may be tied of various materials, but most commonly are made of monofilament.
Wire lines are frequently used as leaders to prevent the fishing line from being severed by toothy fish. Usually braided from several metal strands, wire lines may be made of stainless steel, titanium, or a combination of metal alloys coated with plastic.
Stainless-steel line leaders provide:
Titanium fishing leaders are actually titanium–nickel alloys that have several very important features:
Copper, monel and lead-core fishing lines are used as heavy trolling main lines, usually followed with fluorocarbon line near the lure or bait with fishing swivel between the lines. Due to their high density, these fishing lines sink rapidly in water and require less line for achieving desired trolling depth. On the other hand, these lines are relatively thick for desired strength, especially when compared with braided fishing lines and often require reels with larger spools.
Discarded monofilament fishing line takes up to 600 years to decompose. [6] There have been several types of biodegradable fishing lines developed to minimize the impact on the environment. [7] [8] [9] [10]
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.
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.
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 fish hook or fishhook, formerly also called angle, is a hook used to catch fish either by piercing and embedding onto the inside of the fish mouth (angling) or, more rarely, by impaling and snagging the external fish body. Fish hooks are normally attached to a line, which tethers the target fish to the angler for retrieval, and are typically dressed with some form of bait or lure that entices the fish to swallow the hook out of its own natural instinct to forage or hunt.
Monofilament fishing line is fishing line made from a single fiber of plastic material, as opposed to multifilament or braided fishing lines constructed from multiple strands of fibers. Most fishing lines are now nylon monofilament because they are cheap to manufacture and can be produced in a range of diameters which have different tensile strengths. Monofilament line is also available in different colors, such as clear, white, green, blue, red, and fluorescent.
Flossers are anglers who use the method of bottom bouncing or lining to catch fish, mainly the salmonid species. The technique is commonly practiced in British Columbia during the summer months, when sockeye and chinook salmon run upstream the Fraser River to spawn.
The nail knot, also known as the tube knot or gryp knot, is mostly used in carp and fly-fishing. The nail knot was named because a nail was inserted as a guide when threading the line. Today, it is easier to use a small straw. The nail knot is an important fishing knot used to join two lines of different diameters and allows for line diameters to diminish down to the fly. I.E., it is useful for attaching your backing to the fly line, and your fly line to the leader, or tippet. The knot can be tied in multiple ways and is uniform.
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.
Braided line was one of the earliest types of fishing line, and in its modern incarnations it is still very popular in some situations because of its high knot strength, lack of stretch, and great overall power in relation to its diameter.
Multifilament line, also referred to as The Super Lines, is a type of fishing line. It is a braided line which is made up of ultra-high-molecular-weight polyethylene (UHMWPE), a specialty polyethylene polymer that makes an extremely thin line for its strength. By weight, UHMWPE strands are five to ten times sturdier than steel. Multifilament line is similar to braided dacron in terms of sensitivity but a diameter about one-third that of the ubiquitous nylon monofilament line.
A fishing swivel is a small, usually ball- or barrel-shaped device used in angling to connect sections of fishing lines, consisting of two rings linked via a thrust bearing pivot joint. The line from the rod and reel is tied to the ring at proximal end, and the line leading to the terminal tackles is tied to the other ring at the distal end. Snap swivels have a safety pin-like fastener linked to at least one of the rings, which allows quick detachment and interchanging of different lures.
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.
Drop shotting is a highly finesse angling technique using plastic baits, consisting of a small thin-wire hook with a weight (sinker) attached to the tag end of the line. This is in contrast to the more traditional Texas Rig, where the weight slides inline, resting on the nose of the bait; or the Carolina Rig, where the weight is fixed above the bait. The dropshot rig provides the ability to keep a hook and lure off the bottom with a more "weightless"-looking posture. Usually the bait is fished by letting the weight hit the bottom and then twitch the rod tip, causing the lure to shake in a jumping-like action, but can also be flipped, dragged, hopped or jigged along the bottom. This simple but versatile technique has endless combinations with the different hooks, soft plastics and weights that can be used.[1] The aim is to present a free floating, slow twitching lure to induce a strike from non-aggressive fish. This rig is commonly used in bass fishing for catching smallmouth, largemouth and spotted bass, but can be used for a variety of other bottom-dwelling fish species, as well.
Fly fishing tackle comprises the fishing tackle or equipment typically used by fly anglers. Fly fishing tackle includes:
The uni knot is a multi-purpose fishing knot used in angling that can be used for attaching the fishing line to the spool of a reel, for joining main line to leader/backing lines, and for attaching lures, swivels and snaps.
Tenkara fishing is a type of simple rod angling traditionally practiced in Japan. Primarily used for mountain stream trout fishing, tenkara is still a fairly rare method even among freshwater anglers in Japan, and was largely unknown outside Japan until 2009, when the company Tenkara USA, founded by Daniel Galhardo, introduced and popularized tenkara outside Japan.
A furled leader is a type of knotless tapered fly fishing leader. It is known for high performance, low memory, and soft artificial fly presentation when casting. These attributes are due to the way these leaders are constructed which is similar to creating rope. The big difference is that furled leaders are created with a taper. The twisted style of construction and being made from many filaments leads to a flexible leader with low to no memory like a section of rope.
