Astatotilapia Tweddlei
''Astatotilapia tweddlei'' is a species of fish in the family Cichlidae. It is found in Malawi and Mozambique. Its natural habitats are rivers and freshwater lakes. This species was placed in the genus ''Astatotilapia'' by FishBase which while stating that the taxonomy is uncertain, ''Haplochromis'' is in their view restricted to the rivers and lakes of the drainage basin of Lake Victoria and they tentatively place this species in ''Astatotilapia''. The IUCN state that until further research is undertaken ''A. tweddlei'' should be regarded as restricted to Lakes Chilwa and Chiuta and their drainages, as well as probably through the drainage of the Ruvuma River.

Lake Chiuta
Lake Chiuta is a shallow lake on the border between Malawi and Mozambique. It lies to the north of Lake Chilwa and to the south of Lake Amaramba, which has no outlet, and the lakes are separated by a sandy ridge. Both lakes lie in a graben which runs northeast–southwest, east of the main African Rift Valley. Lake Chiuta is 3–4 meters deep and ranges in size from 25 to 130 square kilometers, depending on the season and rainfall. Lake Chiuta and Amaramba is intermittently linked to the Lugenda River, a tributary of the Ruvuma River. Lake Chiuta can desiccate completely (Owen et al. 198?) Mean Depth: / average surface area: / average volume: / encatchment area: (Ojda 1994) Predominant commercial fish species are ''Oreochromis shiranus shiranus'' (Chambo), ''Clarias gariepinus'' (Mlamba), and ''Barbus paludinosus'' (Matemba). 37 fish species were recorded in total. (Ojda 1994) Dominating aquatic macrophytes are ''Potamogeton welwitschii'' + ''Ceratophyllum demersum'' (submer ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Freshwater Fish Of Africa
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 i ...

Fish Of Mozambique
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. Most f ...

Taxa Named By Peter Brian Neville Jackson
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 intr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Fisheries Science
Fisheries science is the academic discipline of managing and understanding fisheries. It is a multidisciplinary science, which draws on the disciplines of limnology, oceanography, freshwater biology, marine biology, meteorology, conservation, ecology, population dynamics, economics, statistics, decision analysis, management, and many others in an attempt to provide an integrated picture of fisheries. In some cases new disciplines have emerged, as in the case of bioeconomics and fisheries law. Because fisheries science is such an all-encompassing field, fisheries scientists often use methods from a broad array of academic disciplines. Over the most recent several decades, there have been declines in fish stocks (populations) in many regions along with increasing concern about the impact of intensive fishing on marine and freshwater biodiversity. Fisheries science is typically taught in a university setting, and can be the focus of an undergraduate, master's or Ph.D. program. Some ...

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 ...

Ruvuma River
Ruvuma River, formerly also known as the Rovuma River, is a river in the African Great Lakes region. During the greater part of its course, it forms the border between Tanzania and Mozambique (in Mozambique known as ''Rio Rovuma''). The river is long, with a drainage basin of in size. Its mean annual discharge is at its mouth. Overview The lower Ruvuma river is formed by the junction at of two branches of nearly equal importance, the longer of which, the Lujenda, comes from the south-west, the other, which still bears the name Ruvuma, from the west. Its source lies on an undulating plateau, high, immediately to the east of Lake Nyasa, at , the head-stream flowing first due west before turning south and east. In its eastward course, the Ruvuma flows near the base of the escarpment of an arid sandstone plateau to the north, from which direction the streams, which have cut themselves deep channels in the plateau edge, have almost all short courses.
