Upland Bully
The upland bully (''Gobiomorphus breviceps'') is a species of fish in the family Eleotridae endemic to freshwater habitats in New Zealand. Both sexes have distinctive orange-brown dots all over the head. Adults generally reach a length of . Description Male upland bullies are larger and more stocky than females, with bolder markings. The face is profusely marked with orange spots, and there is a cream vertical band at the base of the pectoral fins. Like other ''Gobiomorphus'' species, the first dorsal fin of males features a coloured stripe. The colour of the stripe in upland bullies appears to be locally variable. Many populations have bright orange dorsal stripes, however some have bright green, pink, yellow, cream or uncoloured stripes. Life cycle Upland bullies are neither diadromous nor migratory – they remain in freshwater for their whole lives. Over spring and summer, the male establishes and defends a ‘nest’ – usually a hollow beneath a rock. Males prefer larger ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gerald Stokell
Gerald Stokell (20 June 1890 – 10 July 1972) was a New Zealand amateur ichthyologist.Journal of the Royal Society of New Zealanp 324/ref> Early life Stokell was born at Prebbleton, near Christchurch, New Zealand, on 20 June 1890 to Edmund Stokell and Jane (Née Pasche). He lived there for his whole life. He attended Broadfields Primary School, and was a keen trout angler. Interest in freshwater fish A keen angler, Stokell wrote a series of studies on trout in Lake Ellismere. Through this interest in angling, he also came across native fish species, but was unable to identify them due to a lack of published information. From 1938 onwards he began publishing papers on them, describing species and detangling the many names that had accrued. He described 10 species that are still accepted, although others turned out to be junior synonyms. Species described * ''Galaxias paucispondylus'' (1938) alpine galaxias * '' Gobiomorphus breviceps'' (1939) upland bully * '' Galaxias prognathu ...

Mount Tasman
Mount Tasman (''Horokoau'' in Māori) is New Zealand's second highest mountain, rising to a height of . It is located in the Southern Alps of the South Island, four kilometres to the north of its larger neighbour, Aoraki / Mount Cook. Unlike Aoraki / Mount Cook, Mount Tasman sits on the South Island's Main Divide, on the border between Aoraki / Mount Cook National Park and Westland Tai Poutini National Park. It is the highest point in Westland District. The first ascent of Mount Tasman was in 1895 by Edward FitzGerald and his guide Matthias Zurbriggen. The Māori name (horo: to swallow; koau: shag or ''Phalacrocorax varius'') is believed to refer to the swelling in the neck of a shag when it is swallowing a fish. Aoraki / Mount Cook National Park Mount Tasman is located in Aoraki / Mount Cook National Park in the Canterbury region, which was established in 1953 and along with Westland Tai Poutini National Park, Mount Aspiring National Park and Fiordland National Park forms ...

Endemic Freshwater Fish Of New Zealand
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stewart Island
Stewart Island ( mi, Rakiura, ' glowing skies', officially Stewart Island / Rakiura) is New Zealand's third-largest island, located south of the South Island, across the Foveaux Strait. It is a roughly triangular island with a total land area of . Its coastline is deeply creased by Paterson Inlet (east), Port Pegasus (south), and Mason Bay (west). The island is generally hilly (rising to at Mount Anglem) and densely forested. Flightless birds, including penguins, thrive because there are few introduced predators. Almost all the island is owned by the New Zealand government and over 80 per cent of the island is set aside as the Rakiura National Park. Stewart Island's economy depends on fishing and summer tourism. Its permanent population was recorded at 408 people in the 2018 census, most of whom live in the settlement of Oban on the eastern side of the island. Ferries connect the settlement to Bluff in the South Island. Stewart Island/Rakiura is part of the Southland Dis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hawke's Bay
Hawke's Bay ( mi, Te Matau-a-Māui) is a local government region on the east coast of New Zealand's North Island. The region's name derives from Hawke Bay, which was named by Captain James Cook in honour of Admiral Edward Hawke. The region is governed by Hawke's Bay Regional Council. Geography The region is situated on the east coast of the North Island. It bears the former name of what is now Hawke Bay, a large semi-circular bay that extends for 100 kilometres from northeast to southwest from Māhia Peninsula to Cape Kidnappers. The Hawke's Bay Region includes the hilly coastal land around the northern and central bay, the floodplains of the Wairoa River in the north, the wide fertile Heretaunga Plains around Hastings in the south, and a hilly interior stretching up into the Kaweka and Ruahine Ranges. The prominent peak Taraponui is located inland. Five major rivers flow to the Hawke's Bay coast. From north to south, they are the Wairoa River, Mohaka River, Tutaeku ...

North Island
The North Island, also officially named Te Ika-a-Māui, is one of the two main islands of New Zealand, separated from the larger but much less populous South Island by the Cook Strait. The island's area is , making it the world's 14th-largest island. The world's 28th-most-populous island, Te Ika-a-Māui has a population of accounting for approximately % of the total residents of New Zealand. Twelve main urban areas (half of them officially cities) are in the North Island. From north to south, they are Whangārei, Auckland, Hamilton, Tauranga, Rotorua, Gisborne, New Plymouth, Napier, Hastings, Whanganui, Palmerston North, and New Zealand's capital city Wellington, which is located at the south-west tip of the island. Naming and usage Although the island has been known as the North Island for many years, in 2009 the New Zealand Geographic Board found that, along with the South Island, the North Island had no official name. After a public consultation, the board officially ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hokitika
Hokitika is a town in the West Coast region of New Zealand's South Island, south of Greymouth, and close to the mouth of the Hokitika River. It is the seat and largest town in the Westland District. The town's estimated population is as of . On a clear day Aoraki / Mount Cook can clearly be seen from Hokitika's main street. Toponymy The name Hokitika translates from Māori as "to return directly" (from , 'to return', and , 'direct'). According to the Ministry for Culture and Heritage, the name comes from when a band of Ngāi Tahu warriors in search of greenstone were about to attack Ngāti Wairangi . The chief of the invaders drowned while trying to cross the Hokitika River, and the leaderless (army) then returned directly to their own home. History The land where Hokitika stands was purchased in 1860 from Māori when Poutini Ngāi Tahu chiefs signed the Arahura Deed. This was the sale of the whole of the West Coast region, apart from small areas reserved for Māori ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
South Island
The South Island, also officially named , is the larger of the two major islands of New Zealand in surface area, the other being the smaller but more populous North Island. It is bordered to the north by Cook Strait, to the west by the Tasman Sea, and to the south and east by the Pacific Ocean. The South Island covers , making it the world's 12th-largest island. At low altitude, it has an oceanic climate. The South Island is shaped by the Southern Alps which run along it from north to south. They include New Zealand's highest peak, Aoraki / Mount Cook at . The high Kaikōura Ranges lie to the northeast. The east side of the island is home to the Canterbury Plains while the West Coast is famous for its rough coastlines such as Fiordland, a very high proportion of native bush and national parks, and the Fox and Franz Josef Glaciers. The main centres are Christchurch and Dunedin. The economy relies on agriculture and fishing, tourism, and general manufacturing and services. ...

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 sexes or mating types can produce fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology, behaviour or ecological niche. In addition, paleontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. However, only about 14% of these had been described by 2011. All species (except viruses) are given a two-part name, a "binomial". The first part of a binomial is the genus to which the species belongs. The second part is called the specific name or the specific epithet (in botanical nomenclature, also sometimes i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Diadromous
Fish migration is mass relocation by fish from one area or body of water to another. Many types of fish migrate on a regular basis, on time scales ranging from daily to annually or longer, and over distances ranging from a few metres to thousands of kilometres. Such migrations are usually done for better feeding or to reproduce, but in other cases the reasons are unclear. Fish migrations involve movements of schools of fish on a scale and duration larger than those arising during normal daily activities. Some particular types of migration are ''anadromous'', in which adult fish live in the sea and migrate into fresh water to spawn; and ''catadromous'', in which adult fish live in fresh water and migrate into salt water to spawn. Marine forage fish often make large migrations between their spawning, feeding and nursery grounds. Movements are associated with ocean currents and with the availability of food in different areas at different times of year. The migratory movements ma ...

Gobiomorphus
''Gobiomorphus'' is a genus of fishes in the family Eleotridae native to New Zealand and Australia. They are typically small, benthic fishes with large, rounded fins and two dorsal fins. Many have an amphidromous lifecycle: the eggs are laid in fresh water, but the fry are dispersed to sea soon after hatching, and grow there for several months before returning to fresh water. Species The recognized species in this genus are: * '' Gobiomorphus alpinus'' ( Stokell, 1962) (Tarndale bully) * '' Gobiomorphus australis'' ( Krefft, 1864) (striped gudgeon) * '' Gobiomorphus basalis'' (Gray, 1842) (Cran's bully) * '' Gobiomorphus breviceps'' (Stokell, 1939) (upland bully) * '' Gobiomorphus cotidianus'' ( McDowall, 1975) (common bully) * '' Gobiomorphus coxii'' (Krefft, 1864) (Cox's gudgeon) * '' Gobiomorphus gobioides'' (Valenciennes Valenciennes (, also , , ; nl, label=also Dutch, Valencijn; pcd, Valincyinnes or ; la, Valentianae) is a commune in the Nord department, Hauts-de-Fr ...
