Rosemary Helen Lowe-McConnell
Rosemary Helen Lowe-McConnell (née Rosemary Helen Lowe; 24 June 1921 – 22 December 2014) was an English ichthyologist, ecologist, and limnologist known for research on tilapia and aquaculture. Working in the tropical waters of Africa and South America, Lowe-McConnell was a pioneer in the study of tropical fish ecology and an early adopter of the use of scuba diving for scientific research. Biography Rosemary Helen Lowe was educated at Howell's School in Denbigh, Wales before receiving B.S., M.Sc., and D.Sc. degrees from the University of Liverpool. She went from there to the Freshwater Biological Association, Far Sawrey working on various projects aimed at producing wartime food from fresh waters. Following World War II, in 1945, Lowe-McConnell conducted a survey of tilapia fisheries in the southern part of Lake Nyasa, continuing the previous survey done in 1939 by Ethelwynn Trewavas, Kate Ricardo Bertram, and John Borley. Lowe-McConnell received no support from any fisheries ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cichlid
Cichlids are fish from the family Cichlidae in the order Cichliformes. Cichlids were traditionally classed in a suborder, the Labroidei, along with the wrasses ( Labridae), in the order Perciformes, but molecular studies have contradicted this grouping. The closest living relative of cichlids is probably the convict blenny, and both families are classified in the 5th edition of ''Fishes of the World'' as the two families in the Cichliformes, part of the subseries Ovalentaria. This family is both large and diverse. At least 1,650 species have been scientifically described, making it one of the largest vertebrate families. New species are discovered annually, and many species remain undescribed. The actual number of species is therefore unknown, with estimates varying between 2,000 and 3,000. Many cichlids, particularly tilapia, are important food fishes, while others, such as the ''Cichla'' species, are valued game fish. The family also includes many popular freshwater aquariu ...

Tanzania
Tanzania (; ), officially the United Republic of Tanzania ( sw, Jamhuri ya Muungano wa Tanzania), is a country in East Africa within the African Great Lakes region. It borders Uganda to the north; Kenya to the northeast; Comoro Islands and the Indian Ocean to the east; Mozambique and Malawi to the south; Zambia to the southwest; and Rwanda, Burundi, and the Democratic Republic of the Congo to the west. Mount Kilimanjaro, Africa's highest mountain, is in northeastern Tanzania. According to the United Nations, Tanzania has a population of million, making it the most populous country located entirely south of the equator. Many important hominid fossils have been found in Tanzania, such as 6-million-year-old Pliocene hominid fossils. The genus Australopithecus ranged across Africa between 4 and 2 million years ago, and the oldest remains of the genus ''Homo'' are found near Lake Olduvai. Following the rise of '' Homo erectus'' 1.8 million years ago, humanity spread ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pangani River
The Pangani River (pin-gi'nee) (also called Luffu and Jipe Ruvu, especially in older sources, and probably once called Rhaptus) is a major river of northeastern Tanzania. It has two main sources: the Jipe Ruvu River, Ruvu, which rises as River Lumi, Tanzania, Lumi at Kilimanjaro, passes through Lake Jipe, and empties into the Nyumba ya Mungu Reservoir, and the Kikuletwa, coming from the west and mainly fed by Mount Meru (Tanzania), Mount Meru in Arusha Region, which also enters into the Nyumba ya Mungu Reservoir in Kilimanjaro Region. Just after leaving the reservoir the stream becomes the main Pangani, which empties into the Indian Ocean in Tanga Region at the Tangan port town of Pangani. For much of its length the river flows along the regional borders of Kilimanjaro Region and Manyara Region, before flowing into Tanga Region, which contains the 68 MW Pangani Power Station and the Pangani Falls Dam. There are several inhabited islands within the river. The river is full o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Zigi River
Zigi River also known as Sigi River (Swahili: Mto Sigi ), is a river in located in east Tanga Region in Tanzania. The river rises in the Amani Nature Reserve in the east Usambara Mountains in Muheza District, more precisely in Handei Mountains, at an altitude of 1130 meters and flows for 100 km in a long course and multiple changes of direction to its mouth 40 km north of the town of Tanga in the Indian Ocean The Indian Ocean is the third-largest of the world's five oceanic divisions, covering or ~19.8% of the water on Earth's surface. It is bounded by Asia to the north, Africa to the west and Australia to the east. To the south it is bounded by th .... Its tributaries are the Kihuhui (from south) and the Musi (from North).

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] |
Oreochromis
''Oreochromis'' is a large genus of Oreochromini, oreochromine cichlids, fishes Endemism, endemic to Africa and the Middle East. A few species from this genus have been Introduced species, introduced far outside their native range and are important in Aquaculture of tilapia, aquaculture. Many others have very small ranges; some are seriously Threatened species, threatened, and ''O. ismailiaensis'' and ''O. lidole'' possibly are extinct. Although ''Oreochromis'' primarily are freshwater fish of rivers, lakes and similar habitats, several species can also thrive in brackish waters and some even survive in hypersaline conditions with a salinity that far surpasses that of seawater. In addition to overfishing and habitat loss, some of the more localized species are threatened by the introduction of other, more widespread ''Oreochromis'' species into their ranges. This is because they—in addition to competing for the local resources—often are able to Hybrid (biology), hybridize. '' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Freshwater Fish Of Tanzania
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. ...

Fish Described In 1955
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 ...
