Fishing is an ancient practice that dates back to at least the beginning of the Upper Paleolithic period about 40,000 years ago.[4]Isotopic analysis of the remains of Tianyuan man, a 40,000-year-old modern human from eastern Asia, has shown that he regularly consumed freshwater fish.[5][6]Archaeology features such as shell middens,[7] discarded fish bones, and cave paintings show that seafood was important for survival and consumed in significant quantities. Fishing in Africa is evident very early on in human history. Neanderthals were fishing by about 200,000 BC.[8] People could have developed basketry for fish traps, using spinning and early forms of knitting to make fishing nets[8] able to catch more fish.[9]
During this period, most people lived a hunter-gatherer lifestyle and were, of necessity, constantly on the move. However, where there are early examples of permanent settlements (though not necessarily permanently occupied) such as those at Lepenski Vir, they are almost always associated with fishing as a major source of food.
Trawling
The British dogger was a very early type of sailing trawler from the 17th century, but the modern fishing trawler was developed in the 19th century, at the English fishing port of Brixham. By the early 19th century, the fishers at Brixham needed to expand their fishing area further than ever before due to the ongoing depletion of stocks that was occurring in the overfished waters of South Devon. The Brixham trawler that evolved there was of a sleek build and had a tall gaff rig, which gave the vessel sufficient speed to make long-distance trips out to the fishing grounds in the ocean. They were also sufficiently robust to be able to tow large trawls in deep water. The great trawling fleet that built up at Brixham earned the village the title of 'Mother of Deep-Sea Fisheries'.[10]
This revolutionary design made large-scale trawling in the ocean possible for the first time, resulting in a massive migration of fishers from the ports in the south of England, to villages further north, such as Scarborough, Hull, Grimsby, Harwich and Yarmouth, that were points of access to the large fishing grounds in the Atlantic Ocean.[10]
The small village of Grimsby grew to become the largest fishing port in the world[11] by the mid 19th century. An Act of Parliament was first obtained in 1796, which authorised the construction of new quays and dredging of the Haven to make it deeper.[12] It was only in 1846, with the tremendous expansion in the fishing industry, that the Grimsby Dock Company was formed. The foundation stone for the Royal Dock was laid by Albert the Prince consort in 1849. The dock covered 25 acres (10ha) and was formally opened by Queen Victoria in 1854 as the first modern fishing port.
The elegant Brixham trawler spread across the world, influencing fishing fleets everywhere.[13] By the end of the 19th century, there were over 3,000 fishing trawlers in commission in Britain, with almost 1,000 at Grimsby. These trawlers were sold to fishers around Europe, including from the Netherlands and Scandinavia. Twelve trawlers went on to form the nucleus of the German fishing fleet.[14]
The earliest steam-powered fishing boats first appeared in the 1870s and used the trawl system of fishing as well as lines and drift nets. These were large boats, usually 80–90 feet (24–27m) in length with a beam of around 20 feet (6m). They weighed 40–50 tons and travelled at 9–11 knots (17–20km/h; 10–13mph). David Allen designed and made the earliest purpose-built fishing vessels in Leith, Scotland in March 1875, when he converted a drifter to steam power. In 1877, he built the first screw propelledsteam trawler in the world.[15]
Steam trawlers were introduced at Grimsby and Hull in the 1880s. In 1890 it was estimated that there were 20,000 men on the North Sea. The steam drifter was not used in the herring fishery until 1897. The last sailing fishing trawler was built in 1925 in Grimsby. Trawler designs adapted as the way they were powered changed from sail to coal-fired steam by World War I to diesel and turbines by the end of World War II.
In 1931, the first powered drum was created by Laurie Jarelainen. The drum was a circular device that was set to the side of the boat and would draw in the nets. Since World War II, radio navigation aids and fish finders have been widely used. The first trawlers fished over the side, rather than over the stern. The first purpose-built stern trawler was Fairtry built in 1953 at Aberdeen, Scotland. The ship was much larger than any other trawlers then in operation and inaugurated the era of the 'super trawler'. As the ship pulled its nets over the stern, it could lift out a much greater haul of up to 60 tons.[16] The ship served as a basis for the expansion of 'super trawlers' around the world in the following decades.[16]
The early evolution of fishing as recreation is not clear. For example, there is anecdotal evidence for fly fishing in Japan. However, fly fishing was likely to have been a means of survival, rather than recreation. The earliest English essay on recreational fishing was published in 1496, by Dame Juliana Berners, the prioress of the Benedictine Sopwell Nunnery. The essay was titled Treatyse of Fysshynge wyth an Angle,[17] and included detailed information on fishing waters, the construction of rods and lines, and the use of natural baits and artificial flies.[18]
Recreational fishing took a great leap forward after the English Civil War, where a newly found interest in the activity left its mark on the many books and treatises that were written on the subject at the time. Leonard Mascall in 1589 wrote A booke of Fishing with Hooke and Line along with many others he produced in his life on game and wildlife in England at the time. The Compleat Angler was written by Izaak Walton in 1653 (although Walton continued to add to it for a quarter of a century) and described the fishing in the DerbyshireWye. It was a celebration of the art and spirit of fishing in prose and verse. A second part to the book was added by Walton's friend Charles Cotton.[19]
Charles Kirby designed an improved fishing hook in 1655 that remains relatively unchanged to this day. He went on to invent the Kirby bend, a distinctive hook with an offset point, still commonly used today.[20]

The 18th century was mainly an era of consolidation of the techniques developed in the previous century. Running rings began to appear along the fishing rods, which gave anglers greater control over the cast line. The rods themselves were also becoming increasingly sophisticated and specialised for different roles. Jointed rods became common from the middle of the century and bamboo came to be used for the top section of the rod, giving it much greater strength and flexibility.
The industry also became commercialised – rods and tackle were sold at the haberdashers store. After the Great Fire of London in 1666, artisans moved to Redditch which became a centre of production of fishing-related products from the 1730s. Onesimus Ustonson established his shop in 1761, and his establishment remained a market leader for the next century. He received a royal warrant from three successive monarchs starting with King George IV.[21] He also invented the multiplying winch. The commercialization of the industry came at a time of expanded interest in fishing as a recreational hobby for members of the aristocracy.[22]
The impact of the Industrial Revolution was first felt in the manufacture of fly lines. Instead of anglers twisting their lines – a laborious and time-consuming process – the new textile spinning machines allowed for a variety of tapered lines to be easily manufactured and marketed.
British fly fishing continued to develop in the 19th century, with the emergence of fly fishing clubs, along with the appearance of several books on the subject of fly tying and fly fishing techniques.
By the mid to late 19th century, expanding leisure opportunities for the middle and lower classes began to have an effect on fly fishing, which steadily grew in mass appeal. The expansion of the railway network in Britain allowed the less affluent for the first time to take weekend trips to the seaside or rivers for fishing. Richer hobbyists ventured further abroad.[23] The large rivers of Norway replete with large stocks of salmon began to attract fishers from England in large numbers in the middle of the century – Jones's guide to Norway, and salmon-fisher's pocket companion, published in 1848, was written by Frederic Tolfrey and was a popular guide to the country.[23]
'Nottingham' and 'Scarborough' reel designs.
Modern reel design had begun in England during the latter part of the 18th century, and the predominant model in use was known as the 'Nottingham reel'. The reel was a wide drum that spooled out freely and was ideal for allowing the bait to drift a long way out with the current. Geared multiplying reels never successfully caught on in Britain, but had more success in the United States, where George Snyder of Kentucky modified similar models into his bait-casting reel, the first American-made design in 1810.[24]
The material used for the rod itself changed from the heavy woods native to England to lighter and more elastic varieties imported from abroad, especially from South America and the West Indies. Bamboo rods became the generally favoured option from the mid-19th century, and several strips of the material were cut from the cane, milled into shape, and then glued together to form the light, strong, hexagonal rods with a solid core that were superior to anything that preceded them. George Cotton and his predecessors fished their flies with long rods, and light lines allowing the wind to do most of the work of getting the fly to the fish.[25]
Fishing became a popular recreational activity in the 19th century. Print from Currier and Ives.
Tackle design began to improve in the 1880s. The introduction of new woods to the manufacture of fly rods made it possible to cast flies into the wind on silk lines, instead of horse hair. These lines allowed for a much greater casting distance. However, these early fly lines proved troublesome as they had to be coated with various dressings to make them float and needed to be taken off the reel and dried every four hours or so to prevent them from becoming waterlogged. Another negative consequence was that it became easy for the much longer line to get into a tangle – this was called a 'tangle' in Britain, and a 'backlash' in the US. This problem spurred the invention of the regulator to evenly spool the line out and prevent tangling.[25]
The American, Charles F. Orvis, designed and distributed a novel reel and fly design in 1874, described by reel historian Jim Brown as the "benchmark of American reel design," and the first fully modern fly reel.[26][27]
Albert Illingworth, 1st Baron Illingworth a textiles magnate, patented the modern form of fixed-spool spinning reel in 1905. When casting Illingworth's reel design, the line was drawn off the leading edge of the spool but was restrained and rewound by a line pickup, a device which orbits around the stationary spool. Because the line did not have to pull against a rotating spool, much lighter lures could be cast than with conventional reels.[25]
The development of inexpensive fiberglass rods, synthetic fly lines, and monofilament leaders in the early 1950s revived the popularity of fly fishing.

There are many fishing techniques and tactics for catching fish. The term can also be applied to methods for catching other aquatic animals such as molluscs (shellfish, squid, octopus) and edible marine invertebrates.
Recreational, commercial and artisanal fishers use different techniques, and also, sometimes, the same techniques. Recreational fishers fish for pleasure, sport, or to provide food for themselves, while commercial fishers fish for profit. Artisanal fishers use traditional, low-tech methods, for survival in third-world countries, and as a cultural heritage in other countries. Usually, recreational fishers use angling methods and commercial fishers use netting methods. A modern development is to fish with the assistance of a drone.[28]
Why a fish bites a baited hook or lure involves several factors related to the sensory physiology, behaviour, feeding ecology, and biology of the fish as well as the environment and characteristics of the bait/hook/lure.[29] 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.[30] Some fishers follow fishing folklores which claim that fish feeding patterns are influenced by the position of the sun and the moon.
Fishing tackles are the equipment used by fishers when fishing. Almost any equipment or gear used for fishing can be called a fishing tackle, although the term is most commonly associated with gear used in angling. Some examples are hooks, lines, sinkers, floats, rods, reels, baits, lures, spears, nets, gaffs, traps, waders, and tackle boxes. Fishing techniques refer to the ways the tackles are used when fishing.
Tackles that are attached to the end of a fishing line are collectively called terminal tackles. These include hooks, sinkers, floats, leader lines, swivels, split rings, and any wires, snaps, beads, spoons, blades, spinners and clevises used to attach spinner blades to fishing lures. People also tend to use dead or live bait fish as another form of bait.
A fishing vessel is a boat or ship used to catch fish in the sea, or on a lake or river. Many different kinds of vessels are used in commercial, artisanal, and recreational fishing.
According to the FAO, in 2004 there were four million commercial fishing vessels.[31] About 1.3 million of these are decked vessels with enclosed areas. Nearly all of these decked vessels are mechanised, and 40,000 of them are over 100 tons. At the other extreme, two-thirds (1.8 million) of the undecked boats are traditional craft of various types, powered only by sail and oars.[31] These boats are used by artisan fishers.
It is difficult to estimate how many recreational fishing boats there are, although the number is high. The term is fluid since some recreational boats may also be used for fishing from time to time. Unlike most commercial fishing vessels, recreational fishing boats are often not dedicated just to fishing. Just about anything that will stay afloat can be called a recreational fishing boat, so long as a fisher periodically climbs aboard with the intent to catch a fish. Fish are caught for recreational purposes from boats which range from dugout canoes, float tubes, kayaks, rafts, stand up paddleboards, pontoon boats and small dinghies to runabouts, cabin cruisers and cruising yachts to large, hi-tech and luxurious big game rigs.[32] Larger boats, purpose-built with recreational fishing in mind, usually have large, open cockpits at the stern, designed for convenient fishing.
Recreational and sport fishing refer to fishing primarily for pleasure or competition. Recreational fishing has conventions, rules, licensing restrictions and laws that limit how fish may be caught; typically, these prohibit the use of nets and the catching of fish with hooks not in the mouth. The most common form of recreational fishing is done with a rod, reel, line, hooks and any one of a wide range of baits or lures such as artificial flies. The practice of catching or attempting to catch fish with a hook is generally known as angling. In angling, it is sometimes expected or required that fish be returned to the water (catch and release). Recreational or sport fishermen may log their catches or participate in fishing competitions.
The estimated global number of recreational fishers varies from 220 million to a maximum number of 700 million fishers globally,[33] which is thought to be double the number of individuals working as commercial fishers. In the United States alone it was estimated that 50.1 million people engaged in fishing activities in both saltwater and freshwater environments.[34]
Big-game fishing is fishing from boats to catch large open-water species such as swordfish, tuna, sharks, and marlin. Sportfishing (sometimes game fishing) is recreational fishing where the primary reward is the challenge of finding and catching the fish rather than the culinary or financial value of the fish's flesh. Fish sought after include tarpon, sailfish, mackerel, grouper and many others.
The fishing industry includes any industry or activity concerned with taking, culturing, processing, preserving, storing, transporting, marketing or selling fish or fish products. It is defined by the FAO as including recreational, subsistence and commercial fishing, and the harvesting, processing, and marketing sectors.[35] The commercial activity is aimed at the delivery of fish and other seafood products for human consumption or use as raw material in other industrial processes. In 2022 24% of fishers and fish farmers and 62% of workers in post-harvest sector were women.[36]
There are three principal industry sectors:[note 1]
The commercial sector comprises enterprises and individuals associated with wild-catch or aquaculture resources and the various transformations of those resources into products for sale.
The traditional sector comprises enterprises and individuals associated with fisheries resources from which aboriginal people derive products following their traditions.
The recreational sector comprises enterprises and individuals associated with the purpose of recreation, sport or sustenance with fisheries resources from which products are derived that are not for sale.
Commercial fishing is the capture of fish for commercial purposes. Those who practice it must often pursue fish far from the land under adverse conditions. Commercial fishermen harvest a wide range of aquatic species, from tuna, cod and salmon to shrimp, krill, lobster, clams, squid and crab, in various fisheries for these species. Commercial fishing methods have become very efficient using large nets and sea-going processing factories. Individual fishing quotas and international treaties seek to control the species and quantities caught.
A commercial fishing enterprise may vary from one person with a small boat with hand-casting nets or a few pot traps, to a huge fleet of trawlers processing tons of fish every day.
According to the Food and Agriculture Organization of the United Nations, the total world capture fisheries production in 2000 was 86 million tons (FAO 2002). The top producing countries were, in order, the People's Republic of China (excluding Hong Kong and Taiwan), Peru, Japan, the United States, Chile, Indonesia, Russia, India, Thailand, Norway, and Iceland. Those countries accounted for more than half of the world's production; China alone accounted for a third of the world's production. Of that production, over 90% was marine and less than 10% was inland.
A small number of species support the majority of the world's fisheries. Some of these species are herring, cod, sardine, anchovy, tuna, flounder, mullet, squid, shrimp, salmon, crab, lobster, oyster and scallops. All except these last four provided a worldwide catch of well over a milliontonnes in 1999, with herring and sardines together providing a catch of over 22 million metric tons in 1999. Many other species as well are fished in smaller numbers.
Fish farming is the principal form of aquaculture, while other methods may fall under mariculture. It involves raising fish commercially in tanks or enclosures, usually for food. A facility that releases juvenile fish into the wild for recreational fishing or to supplement a species' natural population is generally referred to as a fish hatchery. Fish species raised by fish farms include salmon, carp, tilapia, catfish, white seabass and trout.
Increased demands on wild fisheries by commercial fishing has caused widespread overfishing. Fish farming offers an alternative solution to the increasing market demand for fish.
Fish and fish products are consumed as food all over the world. With other seafoods, it provides the world's prime source of high-quality protein: 14–16 percent of the animal protein consumed worldwide. Over one billion people rely on fish as their primary source of animal protein.[38]
Fisheries management draws on fisheries science to find ways to protect fishery resources so sustainable exploitation is possible. Modern fisheries management is often referred to as a governmental system of management rules based on defined objectives and a mix of management means to implement the rules, which are put in place by a system of monitoring control and surveillance.
Conservation issues are part of marine conservation, and are addressed in fisheries science programs. There is a growing gap between how many fish are available to be caught and humanity's desire to catch them, a problem that gets worse as the world population grows.
Similar to other environmental issues, there can be conflict between the fishermen who depend on fishing for their livelihoods and fishery scientists who realise that if future fish populations are to be sustainable then some fisheries must limit fishing or cease operations.
Historically, some doubted that fish could experience pain. Laboratory experiments have shown that fish do react to painful stimuli (e.g., injections of bee venom) in a similar way to mammals.[40][41] This is controversial and has been disputed.[further explanation needed][42] The expansion of fish farming as well as animal welfare concerns in society has led to research into more humane and faster ways of killing fish.[43]
In large-scale operations like fish farms, stunning fish with electricity or putting them into water saturated with nitrogen so that they cannot breathe, results in death more rapidly than just taking them out of the water. For sport fishing, it is recommended that fish be killed soon after catching them by hitting them on the head followed by bleeding out or by stabbing the brain with a sharp object[44] (called pithing or ike jime in Japanese). Some believe it is not cruel if you release the catch back to where it was caught however a study in 2018 states that the hook damages an important part of the feeding mechanism by which the fish sucks in food, ignoring the issue of pain.[45]
When fishing there are high chances of catching other marine wildlife in a fishing net. There are over 100 different fishing regulations on paper for reducing this bycatch.[46]
Plastic pollution
Plastic pollution
Abandoned, lost, or otherwise discarded fishing gear includes netting, mono/multifilament lines, hooks, ropes, floats, buoys, sinkers, anchors, metallic materials and fish aggregating devices (FADs) made of non-biodegradable materials such as concrete, metal and polymers. It has been estimated that global fishing gear losses each year include 5.7% of all fishing nets, 8.6% of all traps and 29% of all lines used. Abandoned, lost, or otherwise discarded fishing gear (ALDFG) can have serious impacts on marine organisms through entanglement and ingestion.[47] The potential for fishing gear to become ALDFG depends on a number of factors including:
Environmental factors are mostly related to seafloor topography and obstructions, although tides, currents, waves, winds, and interaction with wildlife are also important.
Operational losses and operator errors can occur even during normal fishing operations.
Problems such as inadequate fisheries management and regulations that do not include adequate controls can hamper collection of ALDFG (e.g. there may be poor access to collection facilities).
Gear loss resulting from conflicts primarily occurs (intentionally or unintentionally) in areas with high concentrations of fishing activities, leading to gear being towed away, fouled, sabotaged or vandalized. Passive and unattended gear such as pots, set gillnets and traps are particularly prone to conflict damage. In the Arctic, conflicts are the most common reason for lost gear.[47]
Cultural impact

Community
For communities like fishing villages, fisheries provide not only a source of food and work but also a community and cultural identity.[48]
Economic
Some locations may be regarded as fishing destinations, which anglers visit on vacation or for competitions. The economic impact of fishing by visitors may be a significant, or even primary driver of tourism revenue for some destinations.
Semantic
A "fishing expedition" is a situation where an interviewer implies they know more than they do to trick their target into divulging more information than they wish to reveal. Other examples of fishing terms that carry a negative connotation are: "fishing for compliments", "to be fooled hook, line and sinker" (to be fooled beyond merely "taking the bait"), and the internet scam of phishing, in which a third party will duplicate a website where the user would put sensitive information (such as bank codes).
Religious
Fishing has had an effect on major religions,[49] including Christianity,[50][51]Hinduism, and the various new age[52] religions. Jesus was said to participate in fishing excursions, and a number of the miracles and many parables and stories reported in the Bible involve fish or fishing. Since the ApostlePeter[53] was a fisherman, the Catholic Church has adopted the use of the fishermans ring into the Pope's traditional vestments.

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.
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 fisherman or fisher is someone who captures fish and other animals from a body of water, or gathers shellfish.
Longline fishing, or longlining, is a commercial fishing angling technique that uses a long main line with baited hooks attached at intervals via short branch lines called snoods or gangions. A snood is attached to the main line using a clip or swivel, with the hook at the other end. Longlines are classified mainly by where they are placed in the water column. This can be at the surface or at the bottom. Lines can also be set by means of an anchor, or left to drift. Hundreds or even thousands of baited hooks can hang from a single line. This can lead to many deaths of different marine species. Longliners – fishing vessels rigged for longlining – commonly target swordfish, tuna, halibut, sablefish and many other species.
Bycatch, in the fishing industry, is a fish or other marine species that is caught unintentionally while fishing for specific species or sizes of wildlife. Bycatch is either the wrong species, the wrong sex, or is undersized or juveniles of the target species. The term "bycatch" is also sometimes used for untargeted catch in other forms of animal harvesting or collecting. Non-marine species that are caught but regarded as generally "undesirable" are referred to as rough fish or coarse fish.
Recreational fishing, also called sport fishing or game fishing, is fishing for leisure, exercise or competition. It can be contrasted with commercial fishing, which is professional fishing for profit; or subsistence fishing, which is fishing for survival and livelihood.
A fishing trawler is a commercial fishing vessel designed to operate fishing trawls. Trawling is a method of fishing that involves actively dragging or pulling a trawl through the water behind one or more trawlers. Trawls are fishing nets that are pulled along the bottom of the sea or in midwater at a specified depth. A trawler may also operate two or more trawl nets simultaneously.
Commercial fishing is the activity of catching fish and other seafood for commercial profit, mostly from wild fisheries. It provides a large quantity of food to many countries around the world, but those who practice it as an industry must often pursue fish far into the ocean under adverse conditions. Large-scale commercial fishing is called industrial fishing.
Artisanal fishing consists of various small-scale, low-technology, low-capital, fishing practices undertaken by individual fisherman. Many of these households are of coastal or island ethnic groups. These households make short fishing trips close to the shore. Their produce is usually not processed and is mainly for local consumption. Artisan fishing uses traditional fishing techniques such as rod and tackle, fishing arrows and harpoons, cast nets, and small traditional fishing boats. For that reason, socio-economic status of artisanal fishing community has become an interest of the authorities in recent years.
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.
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.
The environmental impact of fishing includes issues such as the availability of fish, overfishing, fisheries, and fisheries management; as well as the impact of industrial fishing on other elements of the environment, such as bycatch. These issues are part of marine conservation, and are addressed in fisheries science programs. According to a 2019 FAO report, global production of fish, crustaceans, molluscs and other aquatic animals has continued to grow and reached 172.6 million tonnes in 2017, with an increase of 4.1 percent compared with 2016. There is a growing gap between the supply of fish and demand, due in part to world population growth.
A factory ship, also known as a fish processing vessel, is a large ocean-going vessel with extensive on-board facilities for processing and freezing caught fish or whales. Modern factory ships are automated and enlarged versions of the earlier whalers, and their use for fishing has grown dramatically. Some factory ships are equipped to serve as a mother ship.
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.
Fishing is a prehistoric practice dating back at least 70,000 years. Since the 16th century, fishing vessels have been able to cross oceans in pursuit of fish, and since the 19th century it has been possible to use larger vessels and in some cases process the fish on board. Fish are normally caught in the wild. Techniques for catching fish include hand gathering, spearing, netting, angling and trapping.
There are two major sources of fish in Uganda; one is from aquaculture, the other from fishing in rivers and lakes. The latter has made up the largest and most significant share of all fishing. Open water covers 15.3 percent of Uganda's surface and comprises five major lakes which are the main sources of fish in the country. Lake Victoria continues to be the most important water body in Uganda both in size and contribution to the total fish catch, followed by Lake Albert and Lake Kyoga.
This page is a list of fishing topics.
The following outline is provided as an overview of and topical guide to fishing:
Lift nets, also called lever nets, are a method of fishing using nets that are submerged to a certain depth and then lifted out of the water vertically. The nets can be flat or shaped like a bag, a rectangle, a pyramid, or a cone. Lift nets can be hand-operated, boat-operated, or shore-operated. They typically use bait or a light-source as a fish-attractor. Lift nets are also sometimes called "dip nets", though that term applies more accurately to hand nets.
Fishing gear and methods used in Uganda are both modern and traditional. Fish in Uganda are caught mostly with plank canoes and to a lesser extent, fiberglass boats. Some dugout canoes are also still being used. The plank canoes are generally 4–12 m (13.12–39.37 ft) in length and dugout canoes average 3.5 m (11.48 ft). The total number of vessels is about 17,000 and about 20% of these are motorized. Artisanal fishermen use various gear including gillnets, seines and hook and line. In a number of localities, traditional methods including baskets, traps and mosquito nets continue to be used. The gear commonly used includes gillnets, lift nets, scoop-nets used in light fishing; hook and line gear and fish traps.
