Peruvian Anchoveta
The Peruvian anchoveta (''Engraulis ringens'') is a species of fish of the anchovy family, Engraulidae, from the Southeast Pacific Ocean. It has yielded greater catches than any other single wild fish species in the world, with annual harvests varying between 3.14 and 8.32 million tonnes throughout the 2010s. Almost all of the production is used for the fishmeal industry. The Peruvian anchoveta may be the world's most abundant fish species. Description Anchoveta were previously thought to eat mostly phytoplankton, small zooplankton, and larvae. However, recent work has shown that anchoveta get most of their energy from larger zooplankton, including macrozooplankton. Krill and large copepods are the most important dietary components. Peruvian anchoveta live for up to 3 years, reaching . They first reproduce at about 1 year age and length, whereas they are harvested as early as 6 months of age and length. Distribution Peruvian anchoveta are found in the southeastern ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
IUCN Red List
The International Union for Conservation of Nature (IUCN) Red List of Threatened Species, also known as the IUCN Red List or Red Data Book, founded in 1964, is the world's most comprehensive inventory of the global conservation status of biological species. It uses a set of precise criteria to evaluate the extinction risk of thousands of species and subspecies. These criteria are relevant to all species and all regions of the world. With its strong scientific base, the IUCN Red List is recognized as the most authoritative guide to the status of biological diversity. A series of Regional Red Lists are produced by countries or organizations, which assess the risk of extinction to species within a political management unit. The aim of the IUCN Red List is to convey the urgency of conservation issues to the public and policy makers, as well as help the international community to reduce species extinction. According to IUCN the formally stated goals of the Red List are to provi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
El Niño
El Niño (; ; ) is the warm phase of the El Niño–Southern Oscillation (ENSO) and is associated with a band of warm ocean water that develops in the central and east-central equatorial Pacific (approximately between the International Date Line and 120°W), including the area off the Pacific coast of South America. The ENSO is the cycle of warm and cold sea surface temperature (SST) of the tropical central and eastern Pacific Ocean. El Niño is accompanied by high air pressure in the western Pacific and low air pressure in the eastern Pacific. El Niño phases are known to last close to four years; however, records demonstrate that the cycles have lasted between two and seven years. During the development of El Niño, rainfall develops between September–November. The cool phase of ENSO is es, La Niña, translation=The Girl, with SSTs in the eastern Pacific below average, and air pressure high in the eastern Pacific and low in the western Pacific. The ENSO cycle, including bo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fish Of Peru
Fish are aquatic, craniate, gill-bearing animals that lack limbs with digits. Included in this definition are the living hagfish, lampreys, and cartilaginous and bony fish as well as various extinct related groups. Approximately 95% of living fish species are ray-finned fish, belonging to the class Actinopterygii, with around 99% of those being teleosts. The earliest organisms that can be classified as fish were soft-bodied chordates that first appeared during the Cambrian period. Although they lacked a true spine, they possessed notochords which allowed them to be more agile than their invertebrate counterparts. Fish would continue to evolve through the Paleozoic era, diversifying into a wide variety of forms. Many fish of the Paleozoic developed external armor that protected them from predators. The first fish with jaws appeared in the Silurian period, after which many (such as sharks) became formidable marine predators rather than just the prey of arthropods. Most f ...

Resource Rent
In economics, rent is a surplus value after all costs and normal returns have been accounted for, i.e. the difference between the price at which an output from a resource can be sold and its respective extraction and production costs, including normal return.Scherzer, J. and Sinner, JimResource Rent: Have you paid any lately? Ecologic Research Report No.8, December 2006 This concept is usually termed economic rent but when referring to rent in natural resources such as coastal space or minerals, it is commonly called resource rent. It can also be conceptualised as abnormal or supernormal profit. In practice, identifying and measuring (or collecting) resource rent is not straightforward. At any point in time, rent depends on the availability of information, market conditions, technology and the system of property rights used to govern access to and management of resources. Categories of rent Rent can be categorised into different kinds depending on how it is created. In general on ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Culinary Name
Culinary names, menu names, or kitchen names are names of foods used in the preparation or selling of food, as opposed to their names in agriculture or in scientific nomenclature. The menu name may even be different from the kitchen name. For example, from the 19th until the mid-20th century, many restaurant menus were written in French and not in the local language. Examples include veal (calf), calamari (squid), and sweetbreads (pancreas or thymus gland). Culinary names are especially common for fish and seafood, where multiple species are marketed under a single familiar name. Examples Foods may come to have distinct culinary names for a variety of reasons: * Euphemism: the idea of eating some foods may disgust or offend some eaters regardless of their actual taste ** Testicles: Rocky Mountain oysters, Prairie oysters, lamb fries, or animelles ** Fish milt: soft roe or white roe to disguise that is actually sperm not eggs ** Thymus gland and pancreas gland: sweetbreads * ...

Alaska Pollock
The Alaska pollock or walleye pollock (''Gadus chalcogrammus'') is a marine fish species of the cod genus ''Gadus'' and family Gadidae. It is a semi-pelagic Shoaling and schooling, schooling fish widely distributed in the North Pacific Ocean, North Pacific, with largest concentrations found in the eastern Bering Sea. Name and differentiation Alaska pollock was long put in its own genus, ''Theragra'', and classified as ''Theragra chalcogramma'', but research in 2008 has shown it is rather closely related to the Atlantic cod and should therefore be moved back to ''Gadus'', where it was originally placed. In 2014, the U.S. Food and Drug Administration announced that the official scientific name for the fish was changed from ''Theragra chalcogramma'' back to its original taxon ''Gadus chalcogrammus'', highlighting its close genetic relationship to the other species of the cod genus ''Gadus''. Since 2014, registries of scientific names for fish species (e.g. the United Nations’ ASF ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Thermocline
A thermocline (also known as the thermal layer or the metalimnion in lakes) is a thin but distinct layer in a large body of fluid (e.g. water, as in an ocean or lake; or air, e.g. an atmosphere) in which temperature changes more drastically with depth than it does in the layers above or below. In the ocean, the thermocline divides the upper mixed layer from the calm deep water below. Depending largely on season, latitude, and turbulent mixing by wind, thermoclines may be a semi-permanent feature of the body of water in which they occur, or they may form temporarily in response to phenomena such as the radiative heating/cooling of surface water during the day/night. Factors that affect the depth and thickness of a thermocline include seasonal weather variations, latitude, and local environmental conditions, such as tides and currents. Oceans Most of the heat energy of the sunlight that strikes the Earth is absorbed in the first few centimeters at the ocean's surface, which ...
