Fisheries Science
Fisheries science is the academic discipline of managing and understanding fisheries. It is a multidisciplinary science, which draws on the disciplines of limnology, oceanography, freshwater biology, marine biology, meteorology, conservation, ecology, population dynamics, economics, statistics, decision analysis, management, and many others in an attempt to provide an integrated picture of fisheries. In some cases new disciplines have emerged, as in the case of bioeconomics and fisheries law. Because fisheries science is such an all-encompassing field, fisheries scientists often use methods from a broad array of academic disciplines. Over the most recent several decades, there have been declines in fish stocks (populations) in many regions along with increasing concern about the impact of intensive fishing on marine and freshwater biodiversity. Fisheries science is typically taught in a university setting, and can be the focus of an undergraduate, master's or Ph.D. progra ...

Undergraduate
Undergraduate education is education conducted after secondary education and before postgraduate education, usually in a college or university. It typically includes all postsecondary programs up to the level of a bachelor's degree. For example, in the United States, a student pursuing an associate or bachelor's degree is known as an ''undergraduate student'' while a student who has already obtained a bachelor's degree and is pursuing a higher degree (masters, doctorate) is a ''graduate student''. Upon completion of courses and other requirements of an undergraduate program, the student would earn the corresponding degree. In some other educational systems, undergraduate education is postsecondary education up to and including the level of a master's degree; this is the case for some science courses in Britain and some medicine courses in Europe. By country Africa Nigeria In Nigeria, undergraduate degrees (excluding Medicine, Medical Laboratory Science, Nursing, Engineering, L ...

Ransom A
Ransom refers to the practice of holding a prisoner or item to extort money or property to secure their release. It also refers to the sum of money paid by the other party to secure a captive's freedom. When ransom means "payment", the word comes via Old French ''rançon'' from Latin ''redemptio'', 'buying back'; compare " redemption". Ransom cases Julius Caesar was captured by pirates near the island of Pharmacusa, and held until someone paid 50 talents to free him. In Europe during the Middle Ages, ransom became an important custom of chivalric warfare. An important knight, especially nobility or royalty, was worth a significant sum of money if captured, but nothing if he was killed. For this reason, the practice of ransom contributed to the development of heraldry, which allowed knights to advertise their identities, and by implication their ransom value, and made them less likely to be killed out of hand. Examples include Richard the Lion Heart and Bertrand du Gue ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Rosa Lee
Rosa Mabel Lee (1884-1976) was a British statistician, the first woman scientist to be employed by the Marine Biological Association and the first woman to work as a government fishery scientist in the United Kingdom. Lee studied the growth of fish using the growth rings on their scales. In 1920, she discovered the effect now known as the 'Lee phenomenon' or 'Rosa Lee Phenomenon', and her results are still cited in modern publications. Early years Lee was born in Conwy, Caernarvonshire in 1884. Her father, George Henry Payne Lee was a civil servant, born in Exeter, Devon. Her mother was Maria Agnes, born in St Pancras, London. In 1894, her father worked in Conwy as a postal telegraph inspector. Rosa had two older brothers (Harold and Albert) and two older sisters (Amy and Florence). She graduated from Bangor University in 1904 with a BA in mathematics (Class: II), its first woman graduate in mathematics. Working life Lee was employed by the Marine Biological Association ...

Laboratory
A laboratory (; ; colloquially lab) is a facility that provides controlled conditions in which scientific or technological research, experiments, and measurement may be performed. Laboratories are found in a variety of settings such as schools, universities, privately owned research institutions, corporate research and testing facilities, government regulatory and forensic investigation centers, physicians' offices, clinics, hospitals, regional and national referral centers, and even occasionally personal residences. Overview The organisation and contents of laboratories are determined by the differing requirements of the specialists working within. A physics laboratory might contain a particle accelerator or vacuum chamber, while a metallurgy laboratory could have apparatus for casting or refining metals or for testing their strength. A chemist or biologist might use a wet laboratory, while a psychologist's laboratory might be a room with one-way mirrors and hidden ...

Fishing Vessel
A fishing vessel is a boat or ship used to fishing, catch fish and other valuable nektonic aquatic animals (e.g. shrimps/prawns, krills, coleoids, etc.) in the sea, lake or river. Humans have used different kinds of surface vessels in commercial fishing, commercial, artisan fishing, artisanal and recreational fishing. Prior to the 1950s there was little standardisation of fishing boats. Designs could vary between localities and even different boatyards. Traditional fishing boats were built of wood, which is not often used nowadays because of higher maintenance costs and lower durability. Fibreglass is used increasingly in smaller fishing vessels up to 25 metres (100-tonne displacement), while steel is usually used on vessels above 25 metres. It is difficult to estimate the number of recreational boat fishing, recreational fishing boats. They range in size from small dinghies, sailboats and motorboats to large superyachts and chartered cruiseliners. Unlike commercial fishing vess ...

Sonar
Sonar (sound navigation and ranging or sonic navigation and ranging) is a technique that uses sound propagation (usually underwater, as in submarine navigation) to navigate, measure distances ( ranging), communicate with or detect objects on or under the surface of the water, such as other vessels. "Sonar" can refer to one of two types of technology: ''passive'' sonar means listening for the sound made by vessels; ''active'' sonar means emitting pulses of sounds and listening for echoes. Sonar may be used as a means of acoustic location and of measurement of the echo characteristics of "targets" in the water. Acoustic location in air was used before the introduction of radar. Sonar may also be used for robot navigation, and sodar (an upward-looking in-air sonar) is used for atmospheric investigations. The term ''sonar'' is also used for the equipment used to generate and receive the sound. The acoustic frequencies used in sonar systems vary from very low ( infrasonic) to e ...

Plankton
Plankton are the diverse collection of organisms that drift in Hydrosphere, water (or atmosphere, air) but are unable to actively propel themselves against ocean current, currents (or wind). The individual organisms constituting plankton are called plankters. In the ocean, they provide a crucial source of food to many small and large aquatic organisms, such as bivalves, fish, and baleen whales. Marine plankton include bacteria, archaea, algae, protozoa, microscopic fungi, and drifting or floating animals that inhabit the saltwater of oceans and the brackish waters of estuaries. fresh water, Freshwater plankton are similar to marine plankton, but are found in lakes and rivers. Mostly, plankton just drift where currents take them, though some, like jellyfish, swim slowly but not fast enough to generally overcome the influence of currents. Although plankton are usually thought of as inhabiting water, there are also airborne versions that live part of their lives drifting in the at ...

Fishing Net
A fishing net or fish net is a net (device), net used for fishing. Fishing nets work by serving as an improvised fish trap, and some are indeed rigged as traps (e.g. #Fyke nets, fyke nets). They are usually wide open when deployed (e.g. by casting (fishing), casting or trawling), and then close off when retrieved to engulf and trap fish and other aquatic animals that are larger than the holes/gaps of the net, as well as many unwanted bycatches due to the underwater area a net can cover. Fishing nets are usually meshes formed by knotting a relatively thin thread, and early nets were woven from grasses, vines, flaxes and other fiber crop material, while later woven cotton was used. Modern nets are usually made of artificial polyamides like nylon, although nets of organic polyamides such as wool or silk thread were common until recently and are still used. History Fishing nets have been used widely in the past, including by stone age societies. The oldest known fishing net is ...
