Jean René Constant Quoy
Jean René Constant Quoy (10 November 1790 in Maillé, Vendée, Maillé – 4 July 1869 in Rochefort, Charente-Maritime, Rochefort) was a French naval surgeon, zoologist and anatomist. In 1806, he began his medical studies at the school of naval medicine at Rochefort, Charente-Maritime, Rochefort, afterwards serving as an auxiliary-surgeon on a trip to the Antilles (1808–1809). After earning his medical doctorate in 1814 at Montpellier, he was surgeon-major on a journey to Réunion (1814–1815). Along with Joseph Paul Gaimard, he served as naturalist and surgeon aboard the ''Uranie'' under Louis de Freycinet from 1817 to 1820, and on the ''French ship Astrolabe (1817), Astrolabe'' (1826–1829) under the command of Jules Dumont d'Urville. In July 1823 he and Gaimard presented a paper to the Académie royale des Sciences on the origin of coral reefs, taking issue with the then widespread belief that these were constructed by coral polyps from bases in very deep water and arguin ...

Fish Food
Aquarium fish feed is plant or animal material intended for consumption by pet fish kept in aquariums or ponds. Fish foods normally contain macronutrients, trace elements and vitamins necessary to keep captive fish in good health. Approximately 80% of fishkeeping hobbyists feed their fish exclusively prepared foods that most commonly are produced in flake, pellet or tablet form. Pelleted forms, some of which sink rapidly, are often used for larger fish or bottom feeding species such as loaches or catfish. Some fish foods also contain additives such as sex hormones or beta carotene to artificially enhance the color of ornamental fish. Prepared foods Prepared foods are those foods that are non-living and are made by the aquarist or bought already prepared for consumption for fish. Dry foods Flake food is a type of proprietary or artificially manufactured fish food consumed by a wide variety of tropical and saltwater fish and invertebrates. It is ideally suited to top dwellers and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hardy Fish
A hardy fish is any fish which is easy to maintain in a home aquarium due to its ability to adapt to a wide range of water parameters. Such fish are good starter fish and ideal for 'cycling' an aquarium (i.e. reducing ammonia and nitrites to effectively zero.) Examples of hardy freshwater fish include Poecilids such as the guppy, molly, swordtail and platy, most species In biology, a species is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of the appropriate s ... of betta, zebra danios, and some tetras. Generally, fish are hardy only when they have been tank-bred, since wild-caught fish may take many generations to adapt to life in captivity. Fishkeeping {{Fishkeeping-stub ...

Swan River (Western Australia)
The Swan River () is a river in the south west of Western Australia. The river runs through the metropolitan area of Perth, Western Australia's capital and largest city. Course of river The Swan River estuary flows through the city of Perth. Its lower reaches are relatively wide and deep, with few constrictions, while the upper reaches are usually quite narrow and shallow. The Swan River drains the Avon and coastal plain catchments, which have a total area of about . It has three major tributaries, the Avon River, Canning River and Helena River. The latter two have dams (Canning Dam and Mundaring Weir) which provide a sizeable part of the potable water requirements for Perth and the regions surrounding. The Avon River contributes the majority of the freshwater flow. The climate of the catchment is Mediterranean, with mild wet winters, hot dry summers, and the associated highly seasonal rainfall and flow regime. The Avon rises near Yealering, southeast of Perth: it meand ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tweed River (New South Wales)
The Tweed River is a river situated in the Northern Rivers district of New South Wales, Australia. From the middle reaches of its course, the state boundary between New South Wales and Queensland is located approximately north. The river rises on the eastern slopes of the Great Dividing Range; with its watershed bordered by the McPherson, Burringbar, Condong and Tweed ranges and containing a catchment area of . The river flows generally north east, joined by eight tributaries including the Oxley and Rous rivers before reaching its mouth at its confluence with the Coral Sea of the South Pacific Ocean, south of Point Danger; descending over its course. On its journey, it passes through the major urban centres of Murwillumbah and Tweed Heads. The river's drainage basin consists mostly of the erosion caldera of the Tweed Volcano, a huge extinct volcano of which Mount Warning is the volcanic plug. The Tweed River area has a fine subtropical climate, high rainfall and fertil ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sexing
Through sexing, biologists and agricultural workers determine the sex of livestock and other animals they work with. The specialized trade of chicken sexing has a particular importance in the poultry industry. The sex of mammals can often be determined using sexually dimorphic characteristics. Assisted physical sexing is relevant in vertebrates with cloacae (e.g. birds, reptiles or amphibians) when there is no external sexual dimorphism. In veterinary practice, fibroscopy is used under general anaesthesia in birds such as parrots. Molecular sexing is a set of techniques that use DNA for determining sex in wild or domestic species (population studies, farming, genetics) or humans (archaeology, forensic medicine). Markers commonly used include amelogenin, SRY and ZFX/ZFY. Various techniques have been developed using simple polymerase chain reaction product size dimorphism, presence/absence, restriction Restriction, restrict or restrictor may refer to: Science and techn ...
