Bottom Trawl
Bottom trawling is trawling (towing a trawl, which is a fishing net) along the seafloor. It is also referred to as "dragging". The scientific community divides bottom trawling into benthic trawling and Demersal zone, demersal trawling. Benthic trawling is towing a net at the very bottom of the ocean and demersal trawling is towing a net just above the benthic zone. Bottom trawling can be contrasted with midwater trawling (also known as Pelagic zone, pelagic trawling), where a net is towed higher in the water column. Midwater trawling catches pelagic fish such as anchovies and mackerel, whereas bottom trawling targets both bottom-living fish (groundfish) and semi-pelagic species such as cod, squid, shrimp, and Sebastes, rockfish. Trawling is done by a Fishing trawler, trawler, which can be a small open boat with only or a large factory trawler with . Bottom trawling can be carried out by one trawler or by two trawlers fishing cooperatively (pair trawling). Global catch from bottom ...

Fishing Trawler
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 (double-rig and multi-rig). There are many variants of trawling gear. They vary according to local traditions, bottom conditions, and how large and powerful the trawling boats are. A trawling boat can be a small open boat with only 30 horsepower (22 kW) or a large factory ship with 10,000 horsepower (7457 kW). Trawl variants include beam trawls, large-opening midwater trawls, and large bottom trawls, such as "rock hoppers" that are rigged with heavy rubber wheels that let the net crawl over rocky bottom. History The 17th century saw the development of an early type of sailing ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pair Trawling
Pair trawling is a fishing activity carried out by two boats, with one towing each wikt:warp, warp (the towing cables). As the mouth of the Fishing net, net is kept open by the lateral pull of the individual vessels, Bottom trawling#Otter trawling, otter boards are not required. With the towing power of two boats and no otter boards, a larger net may be worked than would otherwise be possible, or alternatively, the two boats can share increased fuel efficiency. As doors are not necessary, the gear arrangements are simplified, with the warps attaching directly to the wings of the net. Setting and hauling of the nets are carried out by one boat, while the other is only used for towing; usually each will take turns at these operations. Pair trawling is effective on all demersal species. In shallow waters, where the noise from a single vessel may scatter fish, two vessels operating a distance apart tend to herd fish into the path of the net. Catch per vessel often considerably excee ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Orange Roughy
The orange roughy (''Hoplostethus atlanticus''), also known as the red roughy, slimehead and deep sea perch, is a relatively large deep-sea fish belonging to the slimehead family (Trachichthyidae). It is bathypelagic, found in cold (), deep () waters of the Western Pacific Ocean, eastern Atlantic Ocean (from Iceland to Morocco; and from Walvis Bay, Namibia, to off Durban, South Africa), Indo-Pacific (off New Zealand and Australia), and in the eastern Pacific off Chile. The orange roughy is notable for its extraordinary lifespan, attaining over 200 years. The fish has a bright, brick red color, fading to a yellowish-orange after death. Like other slimeheads, orange roughy is slow-growing and late to mature, resulting in a very low stock resilience, making them extremely susceptible to overfishing. Despite this, the species is important to commercial deep- trawl fisheries; many stocks (especially those off New Zealand and Australia, which were first exploited in the late 1970s) ...

Court Of Chancery
The Court of Chancery was a court of equity in England and Wales that followed a set of loose rules to avoid a slow pace of change and possible harshness (or "inequity") of the Common law#History, common law. The Chancery had jurisdiction over all matters of equity (law) , equity, including English trusts law, trusts, English land law, land law, the estates of Mental illness, lunatics and the guardianship of infants. Its initial role differed somewhat: as an extension of the lord chancellor's role as Keeper of the King's Conscience, the court was an administrative body primarily concerned with conscientious law. Thus the Court of Chancery had a far greater remit than the common-law courts (whose decisions it had the jurisdiction to overrule for much of its existence) and was far more flexible. Until the 19th century, the Court of Chancery could apply a far wider range of remedies than common law courts, such as specific performance and injunctions, and had some power to gr ...

Good Parliament
The Good Parliament is the name traditionally given to the English Parliament of 1376. Sitting in London from April 28 to July 10, it was the longest Parliament up until that time. It took place during a time when the English court was perceived by much of the English population to be corrupt, and its traditional name was due to the sincere efforts by its members to reform the government. It had a formidable enemy, however, in John of Gaunt, fourth son of Edward III and the effective ruler of England at the time. In session Parliament had not met since November 1373, two and a half years previously, because Edward III and his councillors recognised the danger of calling a parliament during a period of dissatisfaction. However, the need for funds was so pressing in 1376 that another parliament was necessary. Once the members were assembled, they were determined to clean up the corrupt Royal Council. Peter de la Mare, a knight of the shire representing Herefordshire, had be ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Edward III
Edward III (13 November 1312 – 21 June 1377), also known as Edward of Windsor before his accession, was King of England from January 1327 until his death in 1377. He is noted for his military success and for restoring royal authority after the disastrous and unorthodox reign of his father, Edward II. Edward III transformed the Kingdom of England into one of the most formidable military powers in Europe. His fifty-year reign is List of monarchs in Britain by length of reign#Ten longest-reigning British monarchs, one of the longest in English history, and saw vital developments in legislation and government, in particular the evolution of the English Parliament, as well as the ravages of the Black Death. He outlived his eldest son, Edward the Black Prince, and was succeeded by his grandson, Richard II. Edward was crowned at age fourteen after his father was deposed by his mother, Isabella of France, and her lover, Roger Mortimer, 1st Earl of March, Roger Mortimer. At the age of ...

Environmental Impact Of Aviation
Aircraft engines produce gases, noise, and particulates from fossil fuel combustion, raising environmental concerns over their global effects and their effects on local air quality. Jet airliners contribute to climate change by emitting carbon dioxide (), the best understood greenhouse gas, and, with less scientific understanding, nitrogen oxides, contrails and particulates. Their radiative forcing is estimated at 1.3–1.4 that of alone, excluding induced cirrus cloud with a very low level of scientific understanding. In 2018, global commercial operations generated 2.4% of all emissions. Jet airliners have become 70% more fuel efficient between 1967 and 2007, and emissions per revenue ton-kilometer (RTK) in 2018 were 47% of those in 1990. In 2018, emissions averaged 88 grams of per revenue passenger per km. While the aviation industry is more fuel efficient, overall emissions have risen as the volume of air travel has increased. By 2020, aviation emissions ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Climate Change In Germany
Climate change is leading to long-term effects on agriculture in Germany, more intense heatwaves and coldwaves, flash and coastal flooding, and reduced water availability. Debates over how to address these long-term challenges caused by climate change have also sparked changes in the energy sector and in mitigation strategies. Germany's Energiewende in Germany, energiewende ("energy transition") has been a significant political issue in German politics that has made coalition talks difficult for Angela Merkel, Angela Merkel's CDU/CSU, CDU. Despite massive investments in renewable energy, Germany has struggled to reduce coal usage.

Marine Protected Area
A marine protected area (MPA) is a protected area of the world's seas, oceans, estuaries or in the US, the Great Lakes. These marine areas can come in many forms ranging from wildlife refuges to research facilities. MPAs restrict human activity for a conservation purpose, typically to protect natural or cultural resources. Such marine resources are protected by local, state, territorial, native, regional, national, or international authorities and differ substantially among and between nations. This variation includes different limitations on development, fishing practices, fishing seasons and catch limits, moorings and bans on removing or disrupting marine life. MPAs can provide economic benefits by supporting the fishing industry through the revival of fish stocks, as well as job creation and other market benefits via ecotourism. The value of MPA to mobile species is unknown. There are a number of global examples of large marine conservation areas. The Papahānaumokuākea Mar ...
