Fishing techniques

Major fishing techniques.

Fishing techniques are methods for catching fish. The term may also be applied to catching other aquatic animals such as molluscs (shellfish, squid, octopus) and edible marine invertebrates.

Fishing techniques include hand-gathering, spearfishing, netting, angling and trapping. Recreational, commercial and artisanal fishers use different techniques, and also, sometimes, the same techniques. Recreational fishers fish for pleasure or sport, while commercial fishers fish for profit. Artisanal fishers use traditional, low-tech methods, for survival in developing countries, and as a cultural heritage in other countries. Mostly, recreational fishers use angling methods and commercial fishers use netting methods.

There is an intricate link between various fishing techniques and knowledge about the fish and their behaviour including migration, foraging and habitat. The effective use of fishing techniques often depends on this additional knowledge. Which techniques are appropriate is dictated mainly by the target species and by its habitat.

Fishing techniques can be contrasted with fishing tackle. Fishing tackle refers to the physical equipment that is used when fishing, whereas fishing techniques refers to the manner in which the tackle is used when fishing.

Hand-gathering

It is possible to harvest many sea foods with minimal equipment by using the hands. Gathering seafood by hand can be as easy as picking shellfish or kelp up off the beach, or doing some digging for clams or crabs. The earliest evidence for shellfish gathering dates back to a 300,000-year-old site in France called Terra Amata. This is a hominid site as modern Homo sapiens did not appear in Europe until around 50,000 years ago.

Spearfishing

Spearfishing is an ancient method of fishing conducted with an ordinary spear or a specialized variant such as a harpoon, trident, arrow or eel spear. Some fishing spears use slings (or rubber loops) to propel the spear.

Netting

Fishing nets are meshes usually formed by knotting a relatively thin thread. About 180 AD the Greek author Oppian wrote the Halieutica, a didactic poem about fishing. He described various means of fishing including the use of nets cast from boats, scoop nets held open by a hoop, and various traps "which work while their masters sleep".

Netting is the principal method of commercial fishing, though longlining, trolling, dredging and traps are also used.

Angling

Angling is a method of fishing by means of an "angle" (fish hook). The hook is attached to a line, and is sometimes weighed down by a sinker so it sinks deeper in the water. This is the classic "hook, line and sinker" arrangement, used in angling since prehistoric times. The hook is usually dressed with lures or baits such as earthworm, doughball and bait fish.

Additional arrangements include the use of a fishing rod, which can be fitted with a reel, and functions as a delivery mechanism for casting the line. Other delivery methods for projecting the line include fishing kites and cannons, kontiki rafts and remote controlled devices. Floats can also be used to help set the line or function as bite indicators. The hook can be dressed with lures or bait. Angling is the principal method of sport fishing, but commercial fisheries also use angling methods involving multiple hooks, such as longlining or commercial trolling.

Line fishing

Line fishing is fishing with a fishing line, but not using rods. A fishing line is any cord made for fishing. Important parameters of a fishing line are its length, material, and weight (thicker, sturdier lines are more visible to fish). Factors that may determine what line an angler chooses for a given fishing environment include breaking strength, knot strength, UV resistance, castability, limpness, stretch, abrasion resistance, and visibility.

Modern fishing lines are usually made from artificial substances. The most common type is monofilament, made of a single strand. There are also braided fishing lines and thermally fused superlines.

  • Droplining - a dropline consists of a long fishing line set vertically down into the water, with a series of baited hooks. Droplines have a weight at the bottom and a float at the top. They are not usually as long as longlines and have fewer hooks.
  • Handlining - is fishing with a single fishing line, baited with lures or bait fish, which is held in the hands. Handlining can be done from boats or from the shore. It is used mainly to catch groundfish and squid, but smaller pelagic fish can also be caught.
  • Pahila - is a traditional method of shoreline trolling in the Philippines. It uniquely uses baited hooks tied to a laterally flattened float called palyaw shaped like a small outrigger boat, a catamaran, or a fish. A long line is attached to the float. It is set unto the water's edge and dragged by someone running or walking along the beach. The combination of the water resistance and the diagonal pull forces the float outwards into deeper waters, like a kite. Once it reaches its maximum line length, it moves rapidly parallel to the person pulling it along the beach. It is pulled back to the shore intermittently to check for catches. Pahila literally means "pulled". It is also called subid-subid, sibid-sibid, paguyod, pahinas, hilada, or saliwsiw, among other names, in other Philippine languages.
  • Jiggerpole - is a method of fishing for bass. It is built on using a cane pole with the line of at least 30lb. test, tied well down at the pole of about three quarters length in the typical cane pole manner, and then securely at the tip with about a foot to foot and a half length to drop in the water. Place a swivel on the end of the line. The trick is to linger the lure in a specific area going back and forth, maneuvering the tip of the cane pole in the water causing a noise to attract a bass to see a jig getting after a ripple of water the pole tip is causing.
  • Jigging - is the practice of fishing with a jig, a type of fishing lure. A jig consists of a lead sinker with a hook molded into it and usually covered by a soft body to attract fish. Jigs are intended to create a jerky, vertical motion, as opposed to spinnerbaits which move through the water horizontally.
  • Longlining - is a commercial technique that uses a long heavy fishing line with a series of hundreds or even thousands of baited hooks hanging from the main line by means of branch lines called "snoods". Longlines are usually operated from specialised boats called longliners. They use a special winch to haul in the line, and can operate in deeper waters targeting pelagic species such as swordfish, tuna, halibut and sablefish.
  • Deadline - is the practice of leaving the baited line without a rod (usually over night) and returning for the fish later.
Slab
  • Slabbing: is a bass fishing technique, that involves repetitively lifting and dropping a flat lure, usually made of 1 to 2.5 oz of lead painted to look like a baitfish (or heavy slabs of metal), through a school of actively feeding fish that the angler has located on a fishfinder. Used on white and striped bass in the reservoirs of the southern USA.
  • Trolling - is fishing with one or more baited lines which are drawn through the water. This may be done by pulling the line behind a slow moving boat, or by slowly winding the line in when fishing from the land. Trolling is used to catch pelagic fish such as mackerel and kingfish.

  • Trotlining - a trotline is like a dropline, except that a dropline has a series of hooks suspended vertically in the water, while a trotline has a series of hooks suspended horizontally in the water. Trotlines can be physically set in many ways, such as tying each end to something fixed, and adjusting the set of the rest of the line with weights and floats. They are used for catching crabs or fish, such as catfish, particularly across rivers.

Rod fishing

Angling with fishing rods give more control of the fishing line, and allows the bait/lure to be launched much farther than hand-throwing can reach. The rod is usually fitted with a fishing reel which functions as a mechanism for storing, retrieving and paying out the line. Floats may also be used, and can function as bite indicators. The hook can be dressed with lures or baits.

  • Bank fishing - fishing from river banks and similar shorelines. Bank fishing is usually performed with a fishing rod and reel, although nets, traps, and spears can also be used. People who fish from a boat can sometimes access more areas in prime locations with greater ease than bank fishermen. However, many people do not own boats and find fishing from the bank has its own advantages. Bank fishing has its own requirements, and many things come into play for success, such as local knowledge, water depth, bank structure, location, time of day, and the type of bait and lures.
  • Casting - the act of throwing the fishing line out over the water using a flexible fishing rod. The usual technique is for the angler to quickly flick the rod from behind toward the water. Casting is also a sport adjunct to fishing, much as shooting is to hunting. The sport is supervised by the International Casting Sport Federation, which sponsors tournaments and recognizes world records for accuracy and distance. Some variations of the technique exist, such as Surf fishing, the Reach cast, and Spey casting.
  • Float tubes - small doughnut-shaped boats with an underwater seat in the "hole". Float tubes are used for fly fishing and enable the angler to reach deeper water without splashing and disturbing stillwater fish.
  • Fly fishing - the use of artificial flies as lures. These are cast with specially constructed fly rods and fly lines. The fly line (today, almost always coated with plastic) is heavy enough cast in order to send the fly to the target. Artificial flies vary dramatically in size, weight and colour. Fly fishing is a distinct and ancient angling method, most renowned as a method for catching trout and salmon, but employed today for a wide variety of species including pike, bass, panfish, and carp, as well as marine species, such as redfish, snook, tarpon, bonefish and striped bass. There is a growing population of anglers whose aim is to catch as many different species as possible with the fly.
  • Tenkara fishing - Tenkara is a form of fly fishing that originated in Japan over 200 years ago. It was originally done with a bamboo pole between 12' and 20' with the line tied directly on the tip of the rod requiring no reel. Modern tenkara rods are usually made of graphite and are telescopic. Unlike western style fly fishing tenkara uses either a tapered line or a level line and forgoes the PVC coated fly fishing line. Typical target species include trout and char but most smaller freshwater species can be caught by this method.
  • Rock fishing - fishing from rocky outcrops into the sea. It is a popular pastime in Australia and New Zealand. It can be a dangerous pastime and claims many lives each year.
  • Pitch Fishing - also known as “pitching” or “pitch fishing,” is a technique designed to deliver the lure quietly and at a distance over the water. The lure will fly high and far out over the water, landing in a loud splash. Pitch fishing involves sending the lure out a lower angle, and thus making a smaller splash but still loud as noted in the previous sentence, which will hopefully not scare the fish.
  • Surfcasting - fishing from a shoreline using a rod to cast into the surf. With few exceptions, surf fishing is done in saltwater, often from a beach. The basic idea of most surfcasting is to cast a bait or lure as far out into the water as is necessary to reach the target fish from the shore. This may or may not require long casting distances and muscular techniques. Basic surf fishing can be done with a surfcasting rod between seven and twelve feet long, with an extended butt section, equipped with an appropriate spinning or conventional casting reel. Dedicated surfcasters usually possess an array of terminal and other tackle, with rods and reels of different lengths and actions, and lures and baits of different weights and capabilities. Depending on fishing conditions and the fish they are targeting, such surfcasters tailor bait and terminal tackle to rod and reel and the size and species of the fish. Reels and other equipment need to be constructed so they resist the corrosive and abrasive effects of salt and sand.

Other angling

  • Bottom fishing - is fishing the bottom of a body of water. In the United Kingdom it is called "ledgering". A common rig for fishing on the bottom is a weight tied to the end of the line, with a hook about an inch up line from the weight. The method can be used both with hand lines and rods. There are fishing rods specialized for bottom fishing, called "donkas". The weight is used to cast or throw the line an appropriate distance. Bottom fishing can be done both from boats and from the land. It targets groundfish such as sucker fish, bream, catfish, and crappie.
  • Ice fishing - is the practice of catching fish with lines and hooks through an opening in the ice on a frozen body of water. It is practised by hunter-gatherers such as the Inuit and by anglers in other cold or continental climates.
  • Kayak fishing - has a long history, and has gained popularity in recent times. Many of the techniques used are the same as those used on other fishing boats, apart from difference is in the set-up, how each piece of equipment is fitted to the kayak, and how each activity is carried out on such a small craft.
  • Kite fishing has long been used in China and by the people of New Guinea and other Pacific Islands. Kites can provide the fishermen access to waters that would otherwise be available only with 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 reefs where fish may be plentiful. Kites can also be used for trolling a lure through the water. Suitable kites may be of very simple construction. Those of Tobi Island are a large leaf stiffened by the ribs of the fronds of the coconut palm. The fishing line may be made from coconut fibre and the lure made from spiders webs. Modern kitefishing is popular in New Zealand, where large delta kites of synthetic materials are used to fish from beaches, taking a line and hooks far out past the breakers. Kite fishing is also emerging in Melbourne where sled kites are becoming popular, both off beaches and off boats and in freshwater areas. The disabled community are increasingly using the kites for fishing as they allow mobility impaired people to cast the bait further out than they would otherwise be able to.
  • Kontiki Fishing - is the practice of using either a Kontiki sailing raft, or a modern motorised torpedo device to pull a longline (up to 25 hooks) from the beach up to two thousand metres offshore. This method of fishing is very popular on the surf beaches of New Zealand. The electric kontikis can also be used to pull surfcasting lines and baits offshore, before releasing them to fish. Modern electric kontikis use electric trolling motors, lithium batteries and GPS controlled autopilots, and electric winches are used to retrieve the line, hooks and kontiki back to shore.
  • Boat anglers - Fishing is usually done either from a boat or from a shoreline or river bank. When fishing from a boat, pretty much any fishing technique 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. Some tackle is specialised for boat anglers, such as sea rods.
  • Remote control fishing - Fishing can also be done using a remote controlled boat. This type of fishing is commonly referred to as RC fishing. The boat is usually one to three feet long and runs on a small DC battery. A radio transmitter controls the boat. The fisherman connects the fishing line/bait to the boat; drives it; navigating the water by manipulating the remote controller. The technique is growing in popularity.
  • Drone fishing - Rod fishing assisted by a drone, the drone can be a flying type or underwater type, it can be remote controlled by a human, computer, AI or a combination of the three simultaneously. The drone is used to scout for fish via camera, carry the hook to a far off location, cast the hook, reel in the fish and return. The degree of assistance is adjustable based on the model and configuration of drone used. This technique can be used to catch fish normally requiring a boat. Several US states, including Michigan and Oregon, have banned fishing with drones.

Trapping

Traps are culturally almost universal and seem to have been independently invented many times. There are essentially two types of trap, a permanent or semi-permanent structure placed in a river or tidal area and pot-traps that are baited to attract prey and periodically lifted.

Destructive techniques

Destructive fishing practices are practices that easily result in irreversible damage to aquatic habitats and ecosystems. Many fishing techniques can be destructive if used inappropriately, but some practices are particularly likely to result in irreversible damage. These practices are mostly, though not always, illegal. Where they are illegal, they are often inadequately enforced. Some examples are:

Blast fishing

Dynamite or blast fishing is done easily and cheaply with dynamite or homemade bombs made from locally available materials. Fish are killed by the shock from the blast and are then skimmed from the surface or collected from the bottom. The explosions indiscriminately kill large numbers of fish and other marine organisms in the vicinity and can damage or destroy the physical environment. Explosions are particularly harmful to coral reefs. Blast fishing is also illegal in many waterways around the world.

Bottom trawling

Bottom trawling is trawling (towing a trawl, which is a fishing net) along the sea floor. It is also referred to as "dragging". The scientific community divides bottom trawling into benthic trawling and demersal trawling. Benthic trawling is towing a net at the very bottom of the ocean and demersal trawling is towing a net just above the benthic zone. Bottom trawling targets both bottom-living fish (groundfish) and semi-pelagic species such as cod, squid, shrimp, and rockfish.

Bottom fishing has operated for over a century on heavily fished grounds such as the North Sea and Grand Banks. While overfishing has long been recognised as causing major ecological changes to the fish community on the Grand Banks, concern has been raised more recently about the damage which benthic trawling inflicts upon seabed communities. A species of particular concern is the slow growing, deep water coral Lophelia pertusa. This species is home to a diverse community of deep sea organisms, but is easily damaged by fishing gear. On 17 November 2004, the United Nations General Assembly urged nations to consider temporary bans on high seas bottom trawling.

Cyanide fishing

Cyanide fishing is a method of collecting live fish mainly for use in aquariums, which involves spraying a sodium cyanide mixture into the desired fish's habitat in order to stun the fish. The practice hurts not only the target population, but also many other marine organisms, including coral and thus coral reefs.

Recent studies have shown that the combination of cyanide use and stress of post capture handling results in mortality of up to 75% of the organisms within less than 48 hours of capture. With such high mortality numbers, a greater number of fish must be caught in order to offset post-catch death.

Muro-ami

Muro-ami is a destructive artisan fishing method employed on coral reefs in Southeast Asia, traditionally in Myanmar. An encircling net is used with pounding devices, such as large stones fitted on ropes that are pounded onto the coral reefs. They can also consist of large heavy blocks of cement suspended above the sea by a crane fitted to the vessel. The pounding devices are repeatedly lowered into the area encircled by the net, smashing the coral into small fragments in order to scare the fish out of their coral refuges. The "crushing" effect on the coral heads has been described as having long-lasting and practically totally destructive effects.

History

Ancient remains of spears, hooks and fish net have been found in ruins of the Stone Age. The people of the early civilization drew pictures of nets and fishing lines in their arts (Parker 2002). Early hooks were made from the upper bills of eagles and from bones, shells, horns and plant thorns. Spears were tipped with the same materials, or sometimes with flints. Lines and nets were made from leaves, plant stalk and cocoon silk. Literature on the indigenous fishing practices is very scanty. Baines (1992) documented traditional fisheries in the Solomon Islands. Use of the herbal fish poisons in catching fishes from fresh water and sea documented from New Caledonia (Dahl 1985). John (1998) documented fishing techniques and overall life style of the Mukkuvar fishing Community of Kanyakumari district of Tamil Nadu, India. Tribal people using various plants for medicinal and various purposes (Rai et al. 2000; Singh et al. 1997; Lin 2005) extends the use notion for herbal fish stupefying plants. Use of the fish poisons is very old practice in the history of human kind. In 1212, King Frederick II prohibited the use of certain plant piscicides, and by the 15th century similar laws had been decreed in other European countries as well (Wilhelm 1974). All over the globe, indigenous people use various fish poisons to kill the fishes, documented in America (Jeremy 2002) and among Tarahumara Indian (Gajdusek 1954).
