Chelaethiops Minutus
''Chelaethiops minutus'' is a species of ray-finned fish in the family Cyprinidae. It is endemic to Lake Tanganyika and its outflow, the Lukuga River and is found in Burundi, Democratic Republic of the Congo, Tanzania, and Zambia. Juvenile ''C. minutus'', i.e. those fish up to 75mm in length, live in the shallow waters near the shore. Max Poll discovered that the adult fish inhabit the pelagic zone and grow to 106mm. The adults are frequently caught in association with kapenta The Tanganyika sardine is known as kapenta or matemba in Zambia, Malawi and Zimbabwe (a related but different fish known as dagaa or ndaga is ''Rastrineobola argentea''). Kapenta is two species (Lake Tanganyika sardine, ''Limnothrissa miodon' ..., the freshwater clupeids of Lake Tanganyika. In the light of the fishing lamps ''C. minutus'' and kapenta are readily identifiable from their behaviour.

Chelaethiops Rukwaensis
The Lake Rukwa sardine (''Chelaethiops rukwaensis'') is an African species of freshwater fish in the family Cyprinidae. It is found only in Tanzania. Its natural habitat is freshwater lakes. It is threatened by habitat loss Habitat destruction (also termed habitat loss and habitat reduction) is the process by which a natural habitat becomes incapable of supporting its native species. The organisms that previously inhabited the site are displaced or dead, thereby ....

Cyprinid
Cyprinidae is a family of freshwater fish commonly called the carp or minnow family. It includes the carps, the true minnows, and relatives like the barbs and barbels. Cyprinidae is the largest and most diverse fish family and the largest vertebrate animal family in general with about 3,000 species, of which only 1,270 remain extant, divided into about 370 genera. Cyprinids range from about 12 mm in size to the giant barb (''Catlocarpio siamensis''). By genus and species count, the family makes up more than two-thirds of the ostariophysian order Cypriniformes. The family name is derived from the Greek word ( 'carp'). Biology and ecology Cyprinids are stomachless fish with toothless jaws. Even so, food can be effectively chewed by the gill rakers of the specialized last gill bow. These pharyngeal teeth allow the fish to make chewing motions against a chewing plate formed by a bony process of the skull. The pharyngeal teeth are unique to each species and are used by ...

George Albert Boulenger
George Albert Boulenger (19 October 1858 – 23 November 1937) was a Belgian-British zoologist who described and gave scientific names to over 2,000 new animal species, chiefly fish, reptiles, and amphibians. Boulenger was also an active botanist during the last 30 years of his life, especially in the study of roses. Life Boulenger was born in Brussels, Belgium, the only son of Gustave Boulenger, a Belgian public notary, and Juliette Piérart, from Valenciennes. He graduated in 1876 from the Free University of Brussels with a degree in natural sciences, and worked for a while at the Royal Belgian Institute of Natural Sciences, Brussels, as an assistant naturalist studying amphibians, reptiles, and fishes. He also made frequent visits during this time to the '' Muséum national d'Histoire naturelle'' in Paris and the British Museum in London. In 1880, he was invited to work at the Natural History Museum, then a department of the British Museum, by Dr. Albert C. L. G. Gün ...

Africa
Africa is the world's second-largest and second-most populous continent, after Asia in both cases. At about 30.3 million km2 (11.7 million square miles) including adjacent islands, it covers 6% of Earth's total surface area and 20% of its land area.Sayre, April Pulley (1999), ''Africa'', Twenty-First Century Books. . With billion people as of , it accounts for about of the world's human population. Africa's population is the youngest amongst all the continents; the median age in 2012 was 19.7, when the worldwide median age was 30.4. Despite a wide range of natural resources, Africa is the least wealthy continent per capita and second-least wealthy by total wealth, behind Oceania. Scholars have attributed this to different factors including geography, climate, tribalism, Scramble for Africa, colonialism, the Cold War, neocolonialism, lack of democracy, and corruption. Despite this low concentration of wealth, recent economic expansion and the large and young ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Clupeidae
Clupeidae is a family of ray-finned fishes, comprising, for instance, the herrings, shads, sardines, hilsa, and menhadens. The clupeoids include many of the most important food fishes in the world, and are also commonly caught for production of fish oil and fish meal. Many members of the family have a body protected with shiny cycloid (very smooth and uniform) scales, a single dorsal fin, and a fusiform body for quick, evasive swimming and pursuit of prey composed of small planktonic animals. Due to their small size and position in the lower trophic level of many marine food webs, the levels of methylmercury they bioaccumulate are very low, reducing the risk of mercury poisoning when consumed. Description and biology Clupeids are mostly marine forage fish, although a few species are found in fresh water. No species has scales on the head, and some are entirely scaleless. The lateral line is short or absent, and the teeth are unusually small where they are present at all ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
John Treadwell Nichols
John Treadwell Nichols (June 11, 1883 – November 10, 1958) was an American ichthyologist and ornithologist. Life and career Nichols was born in Jamaica Plain, Boston, Massachusetts, the son of Mary Blake (Slocum) and John White Treadwell Nichols. In 1906 he studied vertebrate zoology at Harvard College, where he graduated with a Bachelor of Arts (AB). In 1907 he joined the American Museum of Natural History as assistant in the department of mammalogy. In 1913 he founded ''Copeia'', the official journal of the American Society of Ichthyologists and Herpetologists. In 1916 he described the long lost Bermuda petrel together with Louis Leon Arthur Mowbray who first sighted this bird within a flock of other petrels in 1906 on Castle Island, Bermuda 45 years before it was officially rediscovered by Mowbray's son Louis. He also described the fish genus ''Bajacalifornia''. He also worked with a team of scientists from the American Museum of Natural History during the Jersey Shore sh ...
