Angling is the activity of aiming to catch fish. Fish are usually caught in the wild. Methods for capturing fish include hand event, spearing, netting, angling and trapping. Angling may include capturing aquatic animals besides fish, such as molluscs, cephalopods, crustaceans, and echinoderms. The term is not usually applied to capturing farmed fish, or to aquatic animals, such as whales where the term whaling is better.

Fishing reports

According to the United Nations FAO stats, the overall number of business anglers and fish farmers is estimated to be 38 million. Fisheries and aquaculture offer direct and indirect employment to over 500 million people in establishing countries. In 2005, the around the world per capita intake of fish recorded from wild fisheries was 14.4 kgs, with an added 7.4 kgs collected from fish farms. Along with supplying food, modern angling is also a leisure leisure activity.


Angling is an old practice that goes back to at least the beginning of the Upper Paleolithic duration about 40,000 years earlier. Isotopic analysis of the skeletal remains of Tianyuan man, a 40,000-year-old modern human from eastern Asia, has revealed that he routinely took in freshwater fish. Archaeology functions such as covering middens, discarded fish bones, and cavern paintings reveal that sea foods were important for survival and consumed in significant amounts.

Throughout this duration, the majority of people lived a hunter-gatherer way of life and were, of necessity, frequently on the action. However, where there are early instances of irreversible negotiations (though not necessarily completely occupied) such as those at Lepenski Vir, they are generally connected with angling as a major resource of food.

Trawling

Englishmen dogger was an earlier kind of sailing trawler from the 17th century, but the current fishing trawler was developed in the 19th century, at the English fishing port of Brixham. By the first 19th century, the fishermen at Brixham had a need to expand their fishing area further than ever before because of 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 large gaff rig, which gave the vessel sufficient speed to create long-distance trips out to the fishing grounds in the ocean. They were also sufficiently robust to manage to tow huge trawls in deep ocean. The great trawling fleet that built up at Brixham, received the village the title of'Mother of Deep-ocean Fisheries.

This extraordinary model made huge scale trawling in the ocean feasible for initially, causing 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 have been points of access to the big fishing grounds in the Atlantic Ocean.

The tiny village of Grimsby grew to become the biggest fishing port on earth by the mid 19th century. An Act of Parliament was initially obtained in 1796, which authorised the construction of new quays and dredging of the Haven to create 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 initial modern fishing port.



The amazing Brixham trawler wide spread across the planet, influence fishing fleets anywhere. By the end of the 19th century, there were over 3,000 fishing trawlers in area in Britain, with merely 1,000 at Grimsby. These trawlers were sold to fishermen accross Europe, including from the Netherlands and Scandinavia. Twelve trawlers proceeded 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. These were large boats, usually 80–90 feet (24–27 m) in length 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 produced by David Allan in Leith, Scotland in March 1875, when he converted a drifter to steam power. In 1877, he built the initial 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 were 20,000 men on the North Sea. The steam drifter was not found in the herring fishery until 1897. The past sailing fishing trawler was built-in 1925 in Grimsby. Trawler designs adapted as how 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 initial powered drum was created by Laurie Jarelainen. The drum was a round 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 now been widely used. The initial trawlers fished over the side, rather than on the stern. The initial purpose built stern trawler was Fairtry built-in 1953 at Aberdeen, Scotland. The ship was much bigger than any other trawlers then functioning and inaugurated the era of the'super trawler '. Because the ship pulled its nets on the stern, it might lift out a much greater haul all the way to 60 tons. The ship served as a basis for the expansion of'super trawlers'around the globe in these decades.
