Melanotaenia Affinis
''Melanotaenia affinis'', the North New Guinea rainbowfish, New Guinea rainbowfish, or red-finned rainbowfish, is a species of rainbowfish endemic to New Guinea (Western New Guinea and Papua New Guinea). It grows to standard length. Of the three known varieties, the so-called standard variety has the widest range. It is commonly found in the Markham, Ramu, and Sepik Rivers; their preferred habitat includes clear rainforest streams, swamps, pools, and lagoons abundant in vegetation and submerged logs. In the aquarium The New Guinea rainbowfish is a peaceful and adaptable rainbowfish species that grows to 14 cm. It favors a pH of 7.0, hard water: (100–150 mg/L) and a temperature of 21–28 C (70 to 82 F). It will eat small live foods and prepared diets. Just like related species, it should be kept in shoals.

Max Carl Wilhelm Weber
Max Carl Wilhelm Weber van Bosse or Max Wilhelm Carl Weber (5 December 1852, in Bonn – 7 February 1937, in Eerbeek) was a German-Dutch zoologist and biogeographer. Weber studied at the University of Bonn, then at the Humboldt University in Berlin with the zoologist Eduard Carl von Martens (1831–1904). He obtained his doctorate in 1877. Weber taught at the University of Utrecht then participated in an expedition to the Barents Sea. He became Professor of Zoology, Anatomy and Physiology at the University of Amsterdam in 1883. In the same year he received naturalised Dutch citizenship. His discoveries as leader of the Siboga Expedition led him to propose Weber's line, which encloses the region in which the mammalian fauna is exclusively Australasian, as an alternative to Wallace's Line. As is the case with plant species, faunal surveys revealed that for most vertebrate groups Wallace’s line was not the most significant biogeographic boundary. The Tanimbar Island group, and ...

Sepik
The Sepik () is the longest river on the island of New Guinea, and the second largest in Oceania by discharge volume after the Fly River. The majority of the river flows through the Papua New Guinea (PNG) provinces of Sandaun (formerly West Sepik) and East Sepik, with a small section flowing through the Indonesian province of Papua. The Sepik has a large catchment area, and landforms that include swamplands, tropical rainforests and mountains. Biologically, the river system is often said to be possibly the largest uncontaminated freshwater wetland system in the Asia-Pacific region. But, in fact, numerous fish and plant species have been introduced into the Sepik since the mid-20th century. Name In 1884, Germany asserted control over the northeast quadrant of the island of New Guinea, which became part of the German colonial empire. The colony was initially managed by the Deutsche Neuguinea-Kompagnie or German New Guinea Company, a commercial enterprise that christened the ter ...

Fishkeeping
Fishkeeping is a popular hobby, practiced by aquarists, concerned with keeping fish in a home aquarium or garden pond. There is also a piscicultural fishkeeping industry, serving as a branch of agriculture. Origins of fishkeeping Fish have been raised as food in pools and ponds for thousands of years. Brightly colored or tame specimens of fish in these pools have sometimes been valued as pets rather than food. Many cultures, ancient and modern, have kept fish for both functional and decorative purposes. Ancient Sumerians kept wild-caught fish in ponds, before preparing them for meals. Depictions of the sacred fish of Oxyrhynchus kept in captivity in rectangular temple pools have been found in ancient Egyptian art. Similarly, Asia has experienced a long history of stocking rice paddies with freshwater fish suitable for eating, including various types of catfish and cyprinid. Selective breeding of carp into today's popular and completely domesticated koi and fancy goldfish b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Freshwater Fish Of Western New Guinea
Fresh water or freshwater is any naturally occurring liquid or frozen water containing low concentrations of dissolved salts and other total dissolved solids. Although the term specifically excludes seawater and brackish water, it does include non- salty mineral-rich waters such as chalybeate springs. Fresh water may encompass frozen and meltwater in ice sheets, ice caps, glaciers, snowfields and icebergs, natural precipitations such as rainfall, snowfall, hail/ sleet and graupel, and surface runoffs that form inland bodies of water such as wetlands, ponds, lakes, rivers, streams, as well as groundwater contained in aquifers, subterranean rivers and lakes. Fresh water is the water resource that is of the most and immediate use to humans. Water is critical to the survival of all living organisms. Many organisms can thrive on salt water, but the great majority of higher plants and most insects, amphibians, reptiles, mammals and birds need fresh water to survive. Fresh water is ...

Endemic Fauna Of New Guinea
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 s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

He has also chaired the National Council for Aviculture, the umbrella organisation for bird-keeping c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ramu
The Ramu River is a major river in northern Papua New Guinea. The headwaters of the river are formed in the Kratke Range from where it then travels about northwest to the Bismarck Sea. Along the Ramu's course, it receives numerous tributaries from the Bismarck Range to the south and the Finisterre and Adelbert. History For many millennia, people have lived along the river, and the river has formed the basis for food, transport, and culture. German exploration The area encompassed by the Ramu was part of Kaiser-Wilhelmsland when Germany established German New Guinea in 1884. The Germans were quick to explore their territory, and the mouth of the Ramu was discovered in 1886 by Vice-Admiral Freiherr von Schleinitz after returning to Finschhafen from an expedition to the nearby Sepik.Souter (1963) p. 73 Schleinitz called the Ramu, ''Ottilien'' after his ship the ''Ottilie''. The course of the river was first discovered 10 years later in 1896 after Dr Carl Lauterbach, a bot ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rainbowfish
The rainbowfish or Melanotaeniidae is a family of small, colourful freshwater fish found in northern and eastern Australia, New Guinea (including islands in Cenderawasih Bay and Raja Ampat Islands in Indonesia), Sulawesi and Madagascar. The largest rainbowfish genus, ''Melanotaenia'', derives from the ancient Greek ''melano'' (black) and ''taenia'' (banded). Translated, it means "black-banded", and is a reference to the often striking lateral black bands that run along the bodies of those in the genus ''Melanotaenia''. Characteristics The Melanotaeniidae is characterised by having their distal premaxillary teeth enlarged. They have a compressed body with the two dorsal fins being separated but with only a small gap between them. There are 3–7 spines in the first dorsal fin while the second has 6–22 rays, with the first ray being a stout spine in some species, the anal fin has 10–30 rays and, again, the first may be a stout spine in some species. The lateral line is either ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Fish Measurement
Fish measurement is the measuring of individual fish and various parts of their anatomies. These data are used in many areas of ichthyology, including taxonomy and fisheries biology. Overall length * Standard length (SL) is the length of a fish measured from the tip of the snout to the posterior end of the last vertebra or to the posterior end of the midlateral portion of the hypural plate. Simply put, this measurement excludes the length of the caudal (tail) fin. * Total length (TL) is the length of a fish measured from the tip of the snout to the tip of the longer lobe of the caudal fin, usually measured with the lobes compressed along the midline. It is a straight-line measure, not measured over the curve of the body. Standard length measurements are used with Teleostei (most bony fish), while total length measurements are used with Myxini (hagfish), Petromyzontiformes (lampreys), and (usually) Elasmobranchii (sharks and rays), as well as some other fishes. Total length meas ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
