Fishing is the task of attempting to catch fish. Fish are normally caught in the wild. Strategies for catching fish include hand gathering, spearing, netting, angling and capturing. Fishing may include catching marine animals aside from fish, such as molluscs, cephalopods, shellfishes, and echinoderms. The term is not normally put on catching farmed fish, or to marine creatures, such as whales where the term whaling is better.

Fishing Statistic

Inning accordance with the United Nations FAO statistics, the overall variety of business fishermen and fish farmers is estimated to be 38 million. Fisheries and tank farming supply direct and indirect employment to over 500 million individuals in creating nations. In 2005, the around the world per capita intake of fish recorded from wild fisheries was 14.4 kilos, with an extra 7.4 kilos collected from fish farms. In addition to providing food, modern-day fishing is likewise an entertainment leisure activity.


Fishing is an old method that goes back to at least the beginning of the Upper Paleolithic period regarding 40,000 years ago. Isotopic analysis of the skeletal remains of Tianyuan guy, a 40,000-year-old modern-day human from eastern Asia, has actually revealed that he routinely took in freshwater fish. Archaeology features such as shell middens, disposed of fish bones, and cavern paints show that sea foods were important for survival and consumed in considerable amounts.

Throughout this period, most individuals lived a hunter-gatherer way of living and were, of necessity, constantly on the action. However, where there are early instances of irreversible settlements (though not necessarily permanently occupied) such as those at Lepenski Vir, they are generally associated with fishing as a significant source of food.

Trawling

Englishmen dogger was an early form 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 first 19th century, the fishermen at Brixham needed to expand their fishing area further than previously as a result of ongoing depletion of stocks that was occurring in the overfished waters of South Devon. The Brixham trawler that evolved there was of a modern build and had a tall gaff rig, which gave the vessel sufficient speed to produce cross country trips out to the fishing grounds in the ocean. These were also sufficiently robust to be able to tow huge trawls in deep ocean. The fantastic trawling fleet that developed at Brixham, received the village the title of'Mother of Deep-ocean Fisheries.

This extraordinary model made huge scale trawling in the ocean possible for initially, producing a spontaneous movement of fishermen from the ports in the South of England, to villages further north, such as for instance Scarborough, Hull, Grimsby, Harwich and Yarmouth, that were points of access to the huge fishing spot in the Atlantic Ocean.

The small village of Grimsby grew to become the biggest fishing port in the world 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 produce it deeper. It was only in the 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 (10 ha) and was formally opened by Queen Victoria in 1854 as the first modern fishing port.



The amazing Brixham trawler wide spread along the world, influencing fishing fleets everywhere. By the conclusion of the 19th century, there have been over 3,000 fishing trawlers in district in Britain, with almost 1,000 at Grimsby. These trawlers were sold to fishermen around Europe, including from the Netherlands and Scandinavia. Twelve trawlers went on to make the nucleus of the German fishing fleet.

The initial steam powered fishing boats first appeared in the 1870s and used the trawl system of fishing along with lines and drift nets. They certainly were large boats, usually 80–90 feet (24–27 m) in total with a beam of around 20 feet (6.1 m). They weighed 40-50 tons and travelled at 9–11 knots (17–20 km/h; 10–13 mph). The initial purpose built fishing vessels were designed and made by David Allan in Leith, Scotland in March 1875, when he converted a drifter to steam power. In 1877, he built the first screw propelled steam trawler in the world.

Steam trawlers were introduced at Grimsby and Hull in the 1880s. In 1890 it had been estimated that there have been 20,000 men on the North Sea. The steam drifter was not used in the herring fishery until 1897. The past 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 conclusion of World War II.

In 1931, the first powered drum was produced 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 initial trawlers fished over the side, as opposed to within the stern. The initial purpose built stern trawler was Fairtry built-in 1953 at Aberdeen, Scotland. The ship was much larger than any other trawlers then functioning and inaugurated the era of the'super trawler '. Whilst the ship pulled its nets within the stern, it might lift out a much greater haul as high as 60 tons. The ship served as a basis for the expansion of'super trawlers'around the globe in the following decades.
