21.01.2021, adminCommercial fishing is the activity of catching fish and other seafood for commercial profitmostly from wild fisheries. It provides a large quantity of food to many countries around the earth, but those who practice it as an industry boay often pursue fish far into the ocean under adverse conditions. Large-scale commercial fishing is also known as industrial fishing.
This profession has commercisl in popularity with biat development of shows such as Deadliest CatchSwordsand Wicked Tuna. The major fishing industries are not biat owned by major corporations but by small commercia, as. This raises concern for fishery managers and researchers, who highlight how further they say that for those reasons, the sustainability of the marine ecosystems could be in danger of collapsing.
Fiehing fishermen harvest a wide variety of animals. However, a very small number of species support the majority of the world's fisheries of these species are herringcodanchovytunaparts of a commercial fishing boat modmulletsquidshrimp parts of a commercial fishing boat mod, salmoncrab partss, lobsteroyster and scallops.
All except these last four provided a worldwide catch of well over a million tonnes inwith herring and sardines together providing a catch of over 22 million metric tons in Many other species are fished in smaller numbers. Inof the million tonnes of fish caught, about 88 percent or over million tonnes were utilized for direct human consumption.
This share ifshing increased significantly in recent decades, as it was bowt percent in the s. Commerciwl industry, inalso managed to generate over billion dollars in sales and also provide over two million jobs in the United States, according to an economic report released by NOAA's Fisheries Service.
The parts of a commercial fishing boat mod has had to adapt through the years in order to keep earning a profit. A study taken on some small family-owned commercial fishing companies showed that they adapted to continue to earn a living but not necessarily make a large profit. Many people working in commercial fishing are self-employed, with some or all parts of a commercial fishing boat mod their pay dependent on the proceeds from the sale of the fish caught.
In the UK, the technical term for this is share fisherman, [5] which refers to anyone working without an employment contract, on a boat manned by more than one person, and relying for their livelihood at least partly on a share of the profits or gross sales cmmercial the fishing parts of a commercial fishing boat mod catch.
Commercial fishing uses many different methods to effectively catch a large variety of species including parts of a commercial fishing boat mod use of pole and line, trolling with multiple lines, trawling with large netsand traps or pots. Fishing methods vary according to the region, the species being fished for, and the technology available to the fishermen. A commercial fishing enterprise may vary from one man with a small baot with hand-casting nets or a few pot trapsto a huge fleet of trawlers processing tons of fish every day.
Commercial fishing gears in use today include surrounding nets e. Commercial fishing gear is specifically designed and updated to avoid catching certain species of animal that is unwanted or endangered. The study showed that most auditory deterrents helped prevent whales from being caught while more physical barriers helped prevent birds from getting tangled within the ;arts. Duringcommercial fishing fatalities occurred in the Boxt States, with fatality rates in different fishing fleets ranging from 21 to deaths perfull-time equivalent workers FTEswhich is many times higher partw the fatality rate for all U.
Boaat causes of fishing-related deaths include vessel disasters, falls overboard, and onboard injuries. Between andmost padts disasters often were initiated by flooding, vessel instability, and large ckmmercial, and that severe weather conditions contributed to a majority of fatal vessel disasters.
The most frequent cause of death is falls overboard. Onboard injuries often result when a crew member is caught in a line and pulled into a winch on deck. The installation of a readily accessible emergency stop switch on the winch can potentially prevent these kinds of injuries.
The U. Coast Guard has primary jurisdiction over the safety of the U. CFIVSA regulations focus primarily on o lives after the loss of a vessel and not on preventing vessels from capsizing or sinking, falls overboard, or injuries on deck. The oceans cover nearly two thirds of the Earth's surface, and are continuously threatened by human behaviors and practices. By taking so many fish from the seas, humans have managed to remove entire links from the marine food chain.
Boa causes a chain effect, leading to an overall upset of the delicate ecological balance. Sharks are one of the ocean's most threatened species because they are mistakenly caught by vessels searching pargs fish, and end up getting tossed back into voat ocean parts of a commercial fishing boat mod or dying [20] This disappearance of sharks has enabled comkercial animals like rays to multiply, which alters the food chain.
Bycatch is the industry term for what they consider "unwanted or economically-worthless aquatic animals who are unintentionally caught using destructively indiscriminate parts of a commercial fishing boat mod methods like longlines and driftnetswhich generally target marketable marine creatures such as tuna and swordfish " [20] There are also billions of other animals that are killed in this manner every year such as: sea turtlesmarine mammals, and sea birds.
Between andit was estimated that 8. Coral reefs are biodiversity -rich ecosystems which provide habitat for millions of aquatic species such as sponges, star fish, jellyfish, sea turtles. Unfortunately, reef ecosystems are highly sensitive to chemical, temperature, and population changes. There has been an increasing disappearance of large predators such as barracudaNassau groupersand sharks [20] This makes the reefs more vulnerable to invasion by non-native species.
Fish farming is the raising of fish for food in underwater enclosures, otherwise known as aquaculture. There are environmental hazards such as waste, damage to ecosystems, and negative effects on humans. These can infect wild fish pars swim near the enclosure, or whole colonies fihsing fish if an infected farm fish escapes the enclosure.
Overfishing occurs because fish are captured at a faster rate than they can reproduce. Both advanced fishing technologies and increased demand for fish have resulted in overfishing. The Food and Agricultural Organization has reported that "about 25 percent of the world's captured fish end up thrown overboard because they are caught unintentionally, are illegal market species, or are of inferior quality and size" [22] It should not go unnoticed that overfishing has caused more ecological extinction than any other human influence on coastal ecosystems.

By BC , the Egyptians knew how to assemble planks of wood into a ship hull. At about the same time, the Scandinavians were also building innovative boats.
People living near Kongens Lyngby in Denmark, came up with the idea of segregated hull compartments, which allowed the size of boats to gradually be increased. A crew of some two dozen paddled the wooden Hjortspring boat across the Baltic Sea long before the rise of the Roman Empire. Scandinavians continued to develop better ships, incorporating iron and other metal into the design and developing oars for propulsion.
By A. They were skilled seamen and boat builders, with clinker-built boat designs that varied according to the type of boat. Trading boats, such as the knarrs , were wide to allow large cargo storage.
Raiding boats, such as the longship , were long and narrow and very fast. The vessels they used for fishing were scaled down versions of their cargo boats. The Scandinavian innovations influenced fishing boat design long after the Viking period came to an end. For example, yoles from the Orkney Island of Stroma were built in the same way as the Norse boats.
In the 15th century, the Dutch 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. The first herring buss was probably built in Hoorn around The ship was about 20 metres long and displaced between 60 and 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 [7] would set to gibbing , salting and barrelling the catch on the broad deck.
During the 17th century, the British developed the dogger , an early type of sailing trawler or longliner , which commonly operated in the North Sea. They could carry a tonne of bait, three tonnes of salt, half a tonne each of food and firewood for the crew, and return with six tonnes of fish. An anchor would have allowed extended periods fishing in the same spot, in waters up to 18 metres deep.
The dogger would also have carried a small open boat for maintaining lines and rowing ashore. A precursor to the dory type was the early French bateau type, a flat bottom boat with straight sides used as early as on the Saint Lawrence River. England, France, Italy, and Belgium have small boats from medieval periods that could reasonably be construed as predecessors of the Dory.
Dories appeared in New England fishing towns sometime after the early 18th century. Lightweight and versatile, with high sides, a flat bottom and sharp bows, they were easy and cheap to build.
The Banks dories appeared in the s. They were designed to be carried on mother ships and used for fishing cod at the Grand Banks.
The British dogger was an 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 fishermen 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'.
This revolutionary design made large scale trawling in the ocean possible for the first time, resulting in a massive migration of fishermen 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. The small village of Grimsby grew to become the largest fishing port in the world by the mid 19th century.
The dock covered 25 acres 10 ha and was formally opened by Queen Victoria in as the first modern fishing port. The facilities incorporated many innovations of the time - the dock gates and cranes were operated by hydraulic power , and the foot 91 m Grimsby Dock Tower was built to provide a head of water with sufficient pressure by William Armstrong.
The elegant Brixham trawler spread across the world, influencing fishing fleets everywhere. Their distinctive sails inspired the song Red Sails in the Sunset , written aboard a Brixham sailing trawler called the Torbay Lass. These trawlers were sold to fishermen around Europe, including from the Netherlands and Scandinavia. Twelve trawlers went on to form the nucleus of the German fishing fleet.
Although fishing vessel designed increasingly began to converge around the world, local conditions still often led the development of different types of fishing boats. The Manx nobby was used around the Isle of Man as a herring drifter.
The fifie was also used as a herring drifter along the east coast of Scotland from the s until well into the 20th century. The earliest steam powered fishing boats first appeared in the s and used the trawl system of fishing as well as 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. The earliest purpose built fishing vessels were designed and made by David Allan in Leith in March , when he converted a drifter to steam power. In , he built the first screw propelled steam trawler in the world. This vessel was Pioneer LH She was of wooden construction with two masts and carried a gaff rigged main and mizen using booms, and a single foresail.
Pioneer is mentioned in The Shetland Times of 4 May In he completed Forward and Onward , steam-powered trawlers for sale. Allan built a total of ten boats at Leith between and Twenty-one boats were completed at Granton , his last vessel being Degrave in The first steam boats were made of wood, but steel hulls were soon introduced and were divided into watertight compartments.
They were well designed for the crew with a large building that contained the wheelhouse and the deckhouse. The boats built in the 20th century only had a mizzen sail , which was used to help steady the boat when its nets were out. The main function of the mast was now as a crane for lifting the catch ashore. It also had a steam capstan on the foredeck near the mast for hauling nets.
The boats had narrow, high funnels so that the steam and thick coal smoke was released high above the deck and away from the fishermen.
These funnels were nicknamed woodbines because they looked like the popular brand of cigarette. These boats had a crew of twelve made up of a skipper , driver, fireman to look after the boiler and nine deck hands.
Steam fishing boats had many advantages. They were usually about 20 ft longer 6.
