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.
The term fishing may be applied to catching other aquatic animals such as shellfish, cephalopods, crustaceans and echinoderms. The term is not usually applied to catching aquatic mammals, such as whales, where the term whaling is more appropriate, or to farmed fish. In addition to providing food, modern fishing is also recreational sport.
According to FAO statistics, the total number of fishermen and fish farmers is estimated to be 38 million. Fisheries and aquaculture provide direct and indirect employment to over 500 million people. In 2005, the worldwide per capita consumption of fish captured from wild fisheries was 14.4 kilograms, with an additional 7.4 kilograms harvested from fish farms.
Prehistory.
Fishing is an ancient practice that dates back at least to the Upper Paleolithic period which began about 40,000 years ago. Isotopic analysis of the skeletal remains of Tianyuan man, a 40,000-year-old modern human from eastern Asia, has shown that he regularly consumed freshwater fish. Archaeological features such as shell middens, discarded fish bones and cave paintings show that sea foods were important for survival and consumed in significant quantities. During this period, most people lived a hunter-gatherer lifestyle and were, out 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.
Spearfishing with barbed poles (harpoons) was widespread in palaeolithic times. Cosquer cave in Southern France contains cave art over 16,000 years old, including drawings of seals which appear to have been harpooned.
The Neolithic culture and technology spread worldwide between 4,000 and 8,000 years ago. With the new technologies of farming and pottery came basic forms of the main fishing methods that are still used today.
From 7500 to 3000 years ago, Native Americans of the California coast were known to engage in fishing with gorge hook and line tackle. In addition, some tribes are known to have used plant toxins to induce torpor in stream fish to enable their capture.
Copper harpoons were known to the seafaring Harappans well into antiquity. Early hunters in India include the Mincopie people, aboriginal inhabitants of India's Andaman and Nicobar islands, who have used harpoons with long cords for fishing since early times.
Early history.
The ancient river Nile was full of fish; fresh and dried fish were a staple food for much of the population. The Egyptians invented various implements and methods for fishing and these are clearly illustrated in tomb scenes, drawings, and papyrus documents. Simple reed boats served for fishing. Woven nets, weir baskets made from willow branches, harpoons and hook and line (the hooks having a length of between eight millimetres and eighteen centimetres) were all being used. By the 12th dynasty, metal hooks with barbs were being used. As is fairly common today, the fish were clubbed to death after capture. Nile perch, catfish and eels were among the most important fish. Some representations hint at fishing being pursued as a pastime.
There are numerous references to fishing in ancient literature; in most cases, however, the descriptions of nets and fishing-gear do not go into detail, and the equipment is described in general terms. An early example from the Bible in Job 41:7: "Canst thou fill his skin with barbed irons? or his head with fish spears?"
Unlike in Minoan culture, fishing scenes are rarely represented in ancient Greek culture, a reflection of the low social status of fishing. There is a wine cup, dating from c. 500 BC, that shows a boy crouched on a rock with a fishing-rod in his right hand and a basket in his left. In the water below there is a rounded object of the same material with an opening on the top. This has been identified as a fish-cage used for keeping live fish, or as a fish-trap. It is clearly not a net. This object is currently in the Museum of Fine Arts, Boston.
Oppian of Corycus, a Greek author wrote a major treatise on sea fishing, the "Halieulica" or "Halieutika", composed between 177 and 180. This is the earliest such work to have survived intact to the modern day. Oppian describes various means of fishing including the use of nets cast from boats, scoop nets held open by a hoop, spears and tridents, and various traps "which work while their masters sleep". Oppian's description of fishing with a "motionless" net is also very interesting:
 "The fishers set up very light nets of buoyant flax and wheel in a circle round about while they violently strike the surface of the sea with their oars and make a din with sweeping blow of poles. At the flashing of the swift oars and the noise the fish bound in terror and rush into the bosom of the net which stands at rest, thinking it to be a shelter: foolish fishes which, frightened by a noise, enter the gates of doom. Then the fishers on either side hasten with the ropes to draw the net ashore."
The Greek historian Polybius ("ca" 203 BC–120 BC), in his "Histories", describes hunting for swordfish by using a harpoon with a barbed and detachable head.
Pictorial evidence of Roman fishing comes from mosaics which show fishing from boats with rod and line as well as nets. Various species such as conger, lobster, sea urchin, octopus and cuttlefish are illustrated. In a parody of fishing, a type of gladiator called retiarius was armed with a trident and a casting-net. He would fight against the murmillo, who carried a short sword and a helmet with the image of a fish on the front.
The Greco-Roman sea god Neptune is depicted as wielding a fishing trident.
In India, the Pandyas, a classical Dravidian Tamil kingdom, were known for the pearl fishery as early as the 1st century BC. Their seaport Tuticorin was known for deep sea pearl fishing. The paravas, a Tamil caste centred in Tuticorin, developed a rich community because of their pearl trade, navigation knowledge and fisheries.
In Norse mythology the sea giantess Rán uses a fishing net to trap lost sailors.
The Moche people of ancient Peru depicted fisherman in their ceramics.
From ancient representations and literature it is clear that fishing boats were typically small, lacking a mast or sail, and were only used close to the shore.
In traditional Chinese history, history begins with three semi-mystical and legendary individuals who taught the Chinese the arts of civilization around 2800–2600 BC: of these Fuxi was reputed to be the inventor of writing, hunting, trapping, and fishing.
Gillnet.
Gillnets existed in ancient times as archaeological evidence from the Middle East demonstrates. In North America, aboriginal fishermen used cedar canoes and natural fibre nets, e.g., made with nettels or the inner bark of cedar. They would attach stones to the bottom of the nets as weights, and pieces of wood to the top, to use as floats. This allowed the net to suspend straight up and down in the water. Each net would be suspended either from shore or between two boats. Native fishers in the Pacific Northwest, Canada, and Alaska still commonly use gillnets in their fisheries for salmon and steelhead.
Both drift gillnets and setnets also have been widely adapted in cultures around the world. The antiquity of gillnet technology is documented by a number of sources from many countries and cultures. Japanese records trace fisheries exploitation, including gillnetting, for over 3,000 years. Many relevant details are available concerning the Edo period (1603–1867). Fisheries in the Shetland Islands, which were settled by Norsemen during the Viking era, share cultural and technological similarities with Norwegian fisheries, including gillnet fisheries for herring. Many of the Norwegian immigrant fishermen who came to fish in the great Columbia River salmon fishery during the second half of the 19th century did so because they had experience in the gillnet fishery for cod in the waters surrounding the Lofoten Islands of northern Norway. Gillnets were used as part of the seasonal round by Swedish fishermen as well. Welsh and English fishermen gillnetted for Atlantic salmon in the rivers of Wales and England in coracles, using hand-made nets, for at least several centuries. These are but a few of the examples of historic gillnet fisheries around the world. Nowadays Gillnets are not used in modern fisheries due to the new regulations and laws put on the commercial fishing industry. The Gillnets would not only kill targeted fish but also harm other unintended inhabitants of the surrounding area, also known as bycatch.
Cod trade.
One of the world's longest lasting trade histories is the trade of dry cod from the Lofoten area to the southern parts of Europe, Italy, Spain and Portugal. The trade in cod started during the Viking period or before, has been going on for more than 1000 years and is still important.
Cod has been an important economic commodity in an international market since the Viking period (around 800 AD). Norwegians used dried cod during their travels and soon a dried cod market developed in southern Europe. This market has lasted for more than 1000 years, passing through periods of Black Death, wars and other crises and still is an important Norwegian fish trade. The Portuguese have been fishing cod in the North Atlantic since the 15th century, and clipfish is widely eaten and appreciated in Portugal. The Basques also played an important role in the cod trade and are believed to have found the Canadian fishing banks in the 16th century. The North American east coast developed in part due to the vast amount of cod, and many cities in the New England area spawned near cod fishing grounds.
Apart from the long history this particular trade also differs from most other trade of fish by the location of the fishing grounds, far from large populations and without any domestic market. The large cod fisheries along the coast of North Norway (and in particular close to the Lofoten islands) have been developed almost uniquely for export, depending on sea transport of stockfish over large distances. Since the introduction of salt, dried salt cod ('klippfisk' in Norwegian) has also been exported. The trade operations and the sea transport were by the end of the 14th century taken over by the Hanseatic League, Bergen being the most important port of trade.
William Pitt the Elder, criticizing the Treaty of Paris in Parliament, claimed that cod was "British gold"; and that it was folly to restore Newfoundland fishing rights to the French. In the 17th and 18th centuries, the New World, especially in Massachusetts and Newfoundland, cod became a major commodity, forming trade networks and cross-cultural exchanges.
Modern trawling.
Early modern designs.
In the 15th century, the Nut developed a type of seagoing herring drifter that became a blueprint for European fishing boats. This was the Herring Buss, used by Dutch herring fishermen until the early 19th centuries. The ship type buss has a long history. It was known around 1000 AD in Scandinavia as a "bǘza", a robust variant of the Viking longship. The first herring buss was probably built in Hoorn around 1415. The last one was built in Vlaardingen in 1841.
The ship was about 20 metres long and displaced between 60 and 100 tons. It was a massive round-bilged keel ship with a bluff bow and stern, the latter relatively high, and with a gallery. The busses used long drifting gill nets to catch the herring. The nets would be retrieved at night and the crews of eighteen to thirty men would set to gibbing, salting and barrelling the catch on the broad deck. The ships sailed in fleets of 400 to 500 ships to the Dogger Bank fishing grounds and the Shetland isles. They were usually escorted by naval vessels, because the English considered they were "poaching". The fleet would stay at sea for weeks at a time. The catch would sometimes be transferred to special ships (called "ventjagers"), and taken home while the fleet would still be at
