Copadichromis Geertsi
''Copadichromis geertsi'' is a species of haplochromine cichlid which is endemic to Lake Malawi. Description ''Copadichromis geertsi'' is a small to medium-sized cichlid, growing to a standard length of , which shows two, occasionally just one, clear spots on the sides. The males are dark in colour with the upper body varying from light blue to yellow towards the head and on the dorsal fin. It can be distinguished from other members of the genus ''Copadichromis'' by the two spots, the colour of the breeding males being black with a pale blue to yellow flash on its head and back. The females and non-breeding males do not have the yellow colour in the anal fin seen females and non breeding males of the otherwise similar '' Copadichromis pleurostigmoides'' and they are grey in colour with two black spots. Distribution ''Copadichromis geertsi'' is endemic to Lake Malawi along the eastern shore from the Nsinje River in Malawi) north as far as Thundu in Mozambique. It has only been r ...

Ad Konings
Adrianus Franciscus Johannes Marinus Maria "Ad" Konings (born 11 January 1956 in Roosendaal, Netherlands) is an ichthyologist originally trained in medicine and biology. Konings is best known for his research on African rift lake cichlids. After studies in Amsterdam, he has spent most of his life in Rotterdam. Early life Konings started keeping cichlids when he was 14 years old in 1970. Soon he was breeding rare African cichlids and working as an assistant to the largest tropical fish dealer in the Netherlands. Academic studies and early career From 1974-1980 he studied medical biology at the University of Amsterdam and was awarded his Ph.D. in 1980. He chose this field despite his love of ichthyology due to a fear that if he chose the latter field he would be unemployable. From 1980-1986. he did research on lysosomal enzymes at the Erasmus University in Rotterdam. Most of this was DNA-related work (molecular biology). In 1986, Konings moved to St. Leon-Rot, Germany (n ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kampango
The kampango or kampoyo (''Bagrus meridionalis'') is a critically endangered species of large and predatory bagrid catfish that is endemic to Lake Malawi, Lake Malombe and the upper Shire River in Africa. It prefers areas near rocks in water shallower than , but it also occurs deeper (not beyond the oxygen limit) and over a sandy or muddy bottom. Appearance and behavior The kampango is among the largest fish in the Lake Malawi basin, reaching up to about long, Konings, Ad (1990). ''Ad Konings' Book of Cichlids and all the other Fishes of Lake Malawi,'' p. 487. or possibly even . A common length is around and females are typically larger than males. Adults are overall blackish, while young are grey with dark spots. During the day kampangos hide in caves, but around dusk or dawn they hunt and eat their prey, primarily cichlids. Breeding The male digs a shallow nest in the sandy bottom, often near rocks, where the female lays several thousand eggs. After hatching, the young mo ...

Fish Of Lake Malawi
Fish are aquatic, craniate, gill-bearing animals that lack limbs with digits. Included in this definition are the living hagfish, lampreys, and cartilaginous and bony fish as well as various extinct related groups. Approximately 95% of living fish species are ray-finned fish, belonging to the class Actinopterygii, with around 99% of those being teleosts. The earliest organisms that can be classified as fish were soft-bodied chordates that first appeared during the Cambrian period. Although they lacked a true spine, they possessed notochords which allowed them to be more agile than their invertebrate counterparts. Fish would continue to evolve through the Paleozoic era, diversifying into a wide variety of forms. Many fish of the Paleozoic developed external armor that protected them from predators. The first fish with jaws appeared in the Silurian period, after which many (such as sharks) became formidable marine predators rather than just the prey of arthropods. Mos ...

Taxonomy Articles Created By Polbot
Taxonomy is the practice and science of categorization or classification (general theory), classification. A taxonomy (or taxonomical classification) is a scheme of classification, especially a hierarchical classification, in which things are organized into groups or types. Among other things, a taxonomy can be used to organize and index knowledge (stored as documents, articles, videos, etc.), such as in the form of a library classification system, or a Taxonomy for search engines, search engine taxonomy, so that users can more easily find the information they are searching for. Many taxonomies are hierarchy, hierarchies (and thus, have an intrinsic tree structure), but not all are. Originally, taxonomy referred only to the categorisation of organisms or a particular categorisation of organisms. In a wider, more general sense, it may refer to a categorisation of things or concepts, as well as to the principles underlying such a categorisation. Taxonomy organizes taxonomic uni ...

Taxa Named By Ad Konings
In biology, a taxon (back-formation from ''taxonomy''; plural taxa) is a group of one or more populations of an organism or organisms seen by taxonomists to form a unit. Although neither is required, a taxon is usually known by a particular name and given a particular ranking, especially if and when it is accepted or becomes established. It is very common, however, for taxonomists to remain at odds over what belongs to a taxon and the criteria used for inclusion. If a taxon is given a formal scientific name, its use is then governed by one of the nomenclature codes specifying which scientific name is correct for a particular grouping. Initial attempts at classifying and ordering organisms (plants and animals) were set forth in Carl Linnaeus's system in ''Systema Naturae'', 10th edition (1758), as well as an unpublished work by Bernard and Antoine Laurent de Jussieu. The idea of a unit-based system of biological classification was first made widely available in 1805 in the intro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lake Tanganyika
Lake Tanganyika () is an African Great Lake. It is the second-oldest freshwater lake in the world, the second-largest by volume, and the second-deepest, in all cases after Lake Baikal in Siberia. It is the world's longest freshwater lake. The lake is shared among four countries—Tanzania, the Democratic Republic of the Congo (DRC), Burundi, and Zambia, with Tanzania (46%) and DRC (40%) possessing the majority of the lake. It drains into the Congo River system and ultimately into the Atlantic Ocean. Etymology "Tanganika" was the name of the lake that Henry Morton Stanley encountered when he was at Ujiji in 1876. The name first originated from the Bembe language when they arrived in South Kivu around the 7th century, they discovered the lake and started calling it “êtanga ‘ya’ni’â” which means “a big river” in their Bantu language. Stanley found also other names for the lake among different ethnic groups, like the Kimana, the Yemba and the Msaga. An alt ...

Specific Name (zoology)
In zoological nomenclature, the specific name (also specific epithet or species epithet) is the second part (the second name) within the scientific name of a species (a binomen). The first part of the name of a species is the name of the genus or the generic name. The rules and regulations governing the giving of a new species name are explained in the article species description. For example, the scientific name for humans is ''Homo sapiens'', which is the species name, consisting of two names: ''Homo'' is the " generic name" (the name of the genus) and ''sapiens'' is the "specific name". Historically, ''specific name'' referred to the combination of what are now called the generic and specific names. Carl Linnaeus, who formalized binomial nomenclature, made explicit distinctions between specific, generic, and trivial names. The generic name was that of the genus, the first in the binomial, the trivial name was the second name in the binomial, and the specific the proper term for ...

Ichthyology
Ichthyology is the branch of zoology devoted to the study of fish, including bony fish ( Osteichthyes), cartilaginous fish (Chondrichthyes), and jawless fish (Agnatha). According to FishBase, 33,400 species of fish had been described as of October 2016, with approximately 250 new species described each year. Etymology The word is derived from the Greek words ἰχθύς, ''ikhthus'', meaning "fish"; and λογία, ''logia'', meaning "to study". History The study of fish dates from the Upper Paleolithic Revolution (with the advent of "high culture"). The science of ichthyology was developed in several interconnecting epochs, each with various significant advancements. The study of fish receives its origins from humans' desire to feed, clothe, and equip themselves with useful implements. According to Michael Barton, a prominent ichthyologist and professor at Centre College, "the earliest ichthyologists were ''hunters and gatherers'' who had learned how to obtain the most use ...

Seine Net
Seine fishing (or seine-haul fishing; ) is a method of fishing that employs a surrounding net, called a seine, that hangs vertically in the water with its bottom edge held down by weights and its top edge buoyed by floats. Seine nets can be deployed from the shore as a beach seine, or from a boat. Boats deploying seine nets are known as seiners. Two main types of seine net are deployed from seiners: ''purse seines'' and ''Danish seines''. A seine differs from a gillnet, in that a seine encloses fish, where a gillnet directly snares fish. Etymology The word ''seine'' has its origins in the Old English ''segne'', which entered the language via Latin ''sagena'', from the original Greek σαγήνη ''sagēnē'' (a drag-net). History Seines have been used widely in the past, including by Stone Age societies. For example, the Māori used large canoes to deploy seine nets which could be over a kilometer long. The nets were woven from green flax, with stone weights and light wood or ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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.
