Beam 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 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 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 rockfish. Trawling is done by a 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 trawling has been estimated at over 30 million tonnes ...

RV Celtic Explorer, Galway Bay, Ireland
A recreational vehicle, often abbreviated as RV, is a motor vehicle or trailer that includes living quarters designed for accommodation. Types of RVs include motorhomes, campervans, coaches, caravans (also known as travel trailers and camper trailers), fifth-wheel trailers, popup campers, and truck campers. Features Typical amenities of an RV include a kitchen, a bathroom, and one or more sleeping facilities. RVs can range from utilitarian – containing only sleeping quarters and basic cooking facilities – to luxurious, with features like air conditioning (AC), water heaters, televisions and satellite receivers, and quartz countertops, for example. RVs can either be trailers (which are towed behind motor vehicles) or self-propelled vehicles. Most RVs are single-deck; however, double-deck RVs also exist. To allow a more compact size while in transit, larger RVs often have expandable sides (called slide-outs) or canopies that are deployed when stationary. History ...

Turtle Excluder Device
A turtle excluder device (TED) is a specialized device that allows a captured sea turtle to escape when caught in a fisherman's net. In particular, sea turtles can be caught when bottom trawling is used by the commercial shrimp fishing industry. In order to catch shrimp, a fine meshed trawl net is needed. This results in large amounts of other marine organisms being also caught as bycatch. When a turtle gets caught or entangled in a trawl net, it becomes trapped and is unable to return to the surface. Since sea turtles are air-breathing animals with lungs, they cannot survive long underwater without surfacing and will eventually drown. History The first TED, was based on a device called the jellyball shooter, that is used to removed cannonball jellyfish from shrimp trawl. TEDs were later developed in the 1970s by Wil Seidel, who worked for NOAA. Some resistance to the use of TEDs has arisen from the belief that the use of the devices actually causes fishermen to lose shrimp ...

Flatfish
A flatfish is a member of the ray-finned demersal fish order Pleuronectiformes, also called the Heterosomata, sometimes classified as a suborder of Perciformes. In many species, both eyes lie on one side of the head, one or the other migrating through or around the head during development. Some species face their left sides upward, some face their right sides upward, and others face either side upward. Many important food fish are in this order, including the flounders, soles, turbot, plaice, and halibut. Some flatfish can camouflage themselves on the ocean floor. Taxonomy Over 800 described species are placed into 16 families. Broadly, the flatfishes are divided into two suborders, Psettodoidei and Pleuronectoidei, with > 99% of the species diversity found within the Pleuronectoidei. The largest families are Soleidae, Bothidae and Cynoglossidae with more than 150 species each. There also exist two monotypic families ( Paralichthodidae and Oncopteridae). Some families ...

Shark
Sharks are a group of elasmobranch fish characterized by a cartilaginous skeleton, five to seven gill slits on the sides of the head, and pectoral fins that are not fused to the head. Modern sharks are classified within the clade Selachimorpha (or Selachii) and are the sister group to the rays. However, the term "shark" has also been used to refer to all extinct members of Chondrichthyes with a shark-like morphology, such as hybodonts and xenacanths. The oldest modern sharks are known from the Early Jurassic. They range in size from the small dwarf lanternshark (''Etmopterus perryi''), a deep sea species that is only in length, to the whale shark (''Rhincodon typus''), the largest fish in the world, which reaches approximately in length. Sharks are found in all seas and are common to depths up to . They generally do not live in freshwater, although there are a few known exceptions, such as the bull shark and the river shark, which can be found in both seawater and fr ...

Barndoor Skate
The barndoor skate (''Dipturus laevis'') is a species of marine cartilaginous fish in the skate family Rajidae of the order Rajiformes. It is native to the northwestern Atlantic Ocean, and is found from the Grand Banks of Newfoundland and the southern side of the Gulf of St. Lawrence south to North Carolina. The fish is one of the largest skates found in the North Atlantic Ocean, reaching lengths up to . It is carnivorous, feeding on invertebrates and other fish found near the sea floor. After peaking in the 1950s, the population of the barndoor skate dramatically declined in the 1960s and early 1970s as a result of overfishing. In 2003, it was listed as endangered by the World Conservation Union. However, barndoor skate populations have increased substantially since 1990 and even surpassed 1960s population size by 2012. In 2019, the barndoor skate was downlisted to least concern by the IUCN based on its largely increased population, new protections within its range, and als ...

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). The UK Marine Conservation Society has categorized orange roughy as "vulnerable to exploitation". It is found in , deep (bathypelagic, ) 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. It is important to commercial deep-trawl fisheries. The fish is 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 resilience, making them extremely susceptible to overfishing. Many stocks (especially those off New Zealand and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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. The Chancery had jurisdiction over all matters of equity, including trusts, land law, the estates of lunatics and the guardianship of infants. Its initial role was somewhat different: 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 grant damages in special circumstances. With the shift of the Exchequer of Pleas toward ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fishery Bulletin
The ''Fishery Bulletin'' is a quarterly peer-reviewed scientific journal published by the National Oceanic and Atmospheric Administration. It was established in 1881 and was until 1903 published as the ''Bulletin of the United States Fish Commission'' by the United States Fish Commission. The journal then went through a number of changes in its name: ''Bulletin of the Bureau of Fisheries'' (1904–1911), ''Bulletin of the United States Fish Commission'' (1912–1940), ''Fishery Bulletin of the Fish and Wildlife Service'' (1941–1970), and finally from 1971, ''Fishery Bulletin''. All content has been scanned and is available through the journal's page or the site maintained by the NOAA Central library. Its editorial board is headed by biologist Jose I. Castro, editor Kathryn Dennis and communicologist Cara Mayo. Currently, it also includes renowned researchers such as Henry L. Bart Jr, Katherine E. Bemis, Matthew D. Campbell, William B. Driggers III, Gretchen L. Grammer, Richar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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, 2½ years previously, because Edward III and his councilors 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 been elected as ... [...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 and Lord of Ireland 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. EdwardIII transformed the Kingdom of England into one of the most formidable military powers in Europe. His fifty-year reign was 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 the throne passed to 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. At age seventeen he led a successful coup d'état against Mortimer, the ''de facto'' ruler of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Environmental Impact Of Aviation
Like other emissions resulting from fossil fuel combustion, aircraft engines produce gases, noise, and particulates, 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.
