Spotted Galaxias
Spotted galaxias (''Galaxias truttaceus'') is a largish, primarily-freshwater galaxias species found in southern Australia. They are a somewhat tubular, deep-bodied fish, with a dusky brownish-red colouration overlain with dark, haloed spots, dramatic black edges to dorsal, anal and pelvic fins, and a dark diagonal stripe through the eye. Distribution Spotted galaxias has a very wide distribution, being found in southern Victoria, all of Tasmania, offshore islands in between, as well as south-west Western Australia. On the mainland spotted galaxias is generally recognised as a freshwater fish species with a marine larval phase (larvae are swept out to sea and return to freshwater habitats as early stage juveniles), and thus only found in coastal rivers. Spotted galaxias are generally found in coastal rivers in Tasmania as well, however natural landlocked populations do occur in some freshwater lakes in Tasmania. Spotted galaxias were assumed not to be native to the Murray-D ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Achille Valenciennes
Achille Valenciennes (9 August 1794 – 13 April 1865) was a French zoology, zoologist. Valenciennes was born in Paris, and studied under Georges Cuvier. His study of parasitic worms in humans made an important contribution to the study of parasitology. He also carried out diverse systematic classifications, linking fossil and current species. He worked with Cuvier on the 22-volume "''Histoire Naturelle des Poissons''" (Natural History of Fish) (1828–1848), carrying on alone after Cuvier died in 1832. In 1832, he succeeded Henri Marie Ducrotay de Blainville (1777–1850) as chair of ''Histoire naturelle des mollusques, des vers et des zoophytes'' at the Muséum national d'histoire naturelle. Early in his career, he was given the task of classifying animals described by Alexander von Humboldt (1769–1859) during his travels in the American tropics (1799 to 1803), and a lasting friendship was established between the two men. He is the binomial authority for many species of fish, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
William Blandowski
Johann Wilhelm Theodor Ludwig von Blandowski, known as William Blandowski (21 January 1822 – 18 December 1878), was a German explorer, soldier, zoologist and mining engineer of Polish descent, famous for his exploration of the Murray and Darling Rivers in Australia. Early life Blandowski was born in Gliwice, Gleiwitz, Upper Silesia, Kingdom of Prussia (now Gliwice, Poland) on 21 January 1822. The youngest of thirteen children his parents, Johann Felix von Blandowski and Leopoldine Gottliebe von Woyrsch were Protestants, and members of the minor Polish aristocracy, using the Wieniawa coat of arms, Wieniawa coat-of-arms. He was educated at the Gymnasium in Lauban but left without gaining his Abitur certificate. He went on to study at the Tarnowitz Mining School and the University of Berlin. Blandowski's education was impacted by the death of his father, financial hardships, and controversies which resulted in quiet expulsions from various institutes. After completing his education ...

Freshwater Fish Of Australia
Freshwater fish of Australia are limited to approximately 280 species, even though the Australian continent is larger than the contiguous United States. The small scale of species found in Australian inland waters is in some part due to the dry conditions of the continent. Rainfall is sporadic over much of the continent, and fish cannot live in many of the desert regions of South Australia and Western Australia. Most freshwater species are found in tropical or subtropical regions. A large proportion of freshwater species are endemic to Australia. The family Percicthyidae (temperate perches) and other families suspected in reality to lie within it (e.g. Gadopsidae, Nannopercidae) have risen to prominence in and dominate many of its freshwater systems, in contrast to the Northern Hemisphere where freshwater fish faunas are overwhelmingly dominated by the carp family, Cyprinidae. (No cyprinid species is native to Australia). Due to the illegal introduction of carp (''Cyprinus carpio' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Galaxias
''Galaxias'' is a genus of small freshwater fish in the family Galaxiidae, and are frequently referred to as the galaxiids. These highly adaptable fish are typically found at temperate latitudes across the Southern Hemisphere. Galaxiids are scaleless and somewhat tubular in body form, ranging from very slender to quite bulky. They are somewhat torpedo-shaped, with the dorsal and anal fins positioned close to the tail. They are generally small, with typical adults ranging between in total length, with some stocky species attaining around . The largest, ''Galaxias argenteus'', has been recorded at , although is a more typical adult length. Species The 46 recognized species in this genus are: * '' Galaxias aequipinnis'' Raadik, 2014 (East Gippsland Galaxias) * '' Galaxias anomalus'' Stokell, 1959 (Roundhead Galaxias) * '' Galaxias arcanus'' Raadik, 2014 (Riffle Galaxias) * '' Galaxias argenteus'' Gmelin, 1789 (Giant Kōkopu) * '' Galaxias auratus'' Johnston, 1883 (Golden ...

Trout
Trout (: trout) is a generic common name for numerous species of carnivorous freshwater ray-finned fishes belonging to the genera '' Oncorhynchus'', ''Salmo'' and ''Salvelinus'', all of which are members of the subfamily Salmoninae in the family Salmonidae. The word ''trout'' is also used for some similar-shaped but non-salmonid fish, such as the spotted seatrout/speckled trout (''Cynoscion nebulosus'', which is actually a croaker). Trout are closely related to salmon and have similar migratory life cycles. Most trout are strictly potamodromous, spending their entire lives exclusively in freshwater lakes, rivers and wetlands and migrating upstream to spawn in the shallow gravel beds of smaller headwater creeks. The hatched fry and juvenile trout, known as ''alevin'' and ''parr'', will stay upstream growing for years before migrating down to larger waterbodies as maturing adults. There are some anadromous species of trout, such as the steelhead (a coastal subs ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kent River
The Kent River is a river in the Great Southern region of Western Australia. The headwaters of the river rise near Tenterden. The river flows in a south-westerly direction, crosses the Muir Highway east of Rocky Gully, flows through Mount Roe and Mount Lindesay national parks, crosses the South Coast Highway near Kenton, flows through the Owingup Nature Reserve swampland and finally discharges into the eastern side of Irwin Inlet. There are two tributaries to the Kent: Styx River and Nile Creek. The river was named in 1829 by Thomas Wilson, the first European to explore the river. He named it after a member of his exploration party John Kent, of the 39th Regiment, Assistant Commissary General at the King George Sound King George Sound (Mineng ) is a sound (geography), sound on the south coast of Western Australia. Named King George the Third's Sound in 1791, it was referred to as King George's Sound from 1805. The name "King George Sound" gradually came in ... ga ...

Angove River
The Angove River or Angove Creek is a river located in the Great Southern region of Western Australia; most of the river is found within Two Peoples Bay Nature Reserve. The stream was seen in 1898 by surveyor William Angove, and was named after him in 1913 by another surveyor, B. W. Ridley. The river rises in swamps north of the water supply reserve then enter the reserve, where a pipehead dam is located to provide potable water to Albany. It then flows through a gauging weir then enters Two Peoples Bay Nature Reserve. It continues through a channel that is on private land and was constructed to drain nearby farm land. The river eventually discharges into Angove Lake. The water is of excellent quality and is considered as fresh, potable water. only 5% of the catchment area had been cleared, mostly in the very upper reaches and around the lake. The catchment area is one of the few areas of Albany Blackbutt Woodland left in Australia and is considered to be an important bio ...

Goodga River
The Goodga River is a river in the Great Southern region of Western Australia. The river is located within the boundaries of Two Peoples Bay Nature Reserve about east of Albany. The river rises to the north of Reservoir Hill and flows in a southerly direction until it discharges into Moates Lake. This lake drains into Gardner Lake and eventually into Two Peoples Bay. The average rainfall in the catchment area is , with most falling in the winter months. The catchment mostly consists of Albany blackbutt (''Eucalyptus staeri'') and sheoak (''Allocasuarina fraseriana'') forest. Approximately one third of the catchment has been cleared for agriculture. The name was first recorded in 1913 by a surveyor and is thought to be of Aboriginal origin. A weir was built along the river in 1964 to measure stream flow; a fishway was built in 2000 to allow fish to migrate upstream of the weir. The river is home to the endangered fish, the trout minnow ('' Galaxias truttaceus''), which ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Snowy Mountains Scheme
The Snowy Mountains Scheme, also known as the Snowy Hydro or the Snowy scheme, is a hydroelectricity and irrigation in Australia, irrigation complex in south-east Australia. Near the border of New South Wales and Victoria (Australia), Victoria, the scheme consists of sixteen major dams; nine power stations; two pumping stations; and of tunnels, pipelines and aqueducts that were constructed between 1949 and 1974. The Scheme was completed under the supervision of Chief Engineer, William Hudson (engineer), Sir William Hudson. It is the largest engineering project undertaken in Australia. The water of the Snowy River and some of its tributary, tributaries, much of which formerly flowed southeast onto the river flats of East Gippsland, and into Bass Strait of the Tasman Sea, is captured at high elevations and diverted inland to the Murray River, Murray and Murrumbidgee Rivers irrigation areas. The Scheme includes two major tunnel systems constructed through the continental divide ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
