Lake Victoria Sardine
The silver cyprinid (''Rastrineobola argentea'') also known as the Lake Victoria sardine, mukene,and omena (native language), dagaa (swahili language) is a species of pelagic, freshwater ray-finned fish in the carp family, Cyprinidae from East Africa. It is the only member of the genus ''Rastrineobola''. Description A small silvery fish which has a strongly compressed body covered in large scales with a pearlescent sheen and a yellow tail, and can grow to a length of . The lateral line is below the midpoint of the body and runs to the lower part of the caudal peduncle. The cheek is covered by delicate suborbital bones. Distribution The silver cyprinid is known from the drainage basin of Lake Victoria, Lake Kyoga, Lake Nabugabo and the Victoria Nile, occurring in Kenya, Uganda and Tanzania.

Jacques Pellegrin
Jacques Pellegrin (12 June 1873, Paris – 12 August 1944) was a French zoologist. In Paris, he worked under zoologist Léon Vaillant (chair of reptiles and fishes) at the ''Muséum national d'histoire naturelle''. From 1897, Pellegrin served as ''préparateur'' at the museum. He obtained doctorates in medicine (1899) and science (1904), and in 1908 was named as an assistant director. After many missions abroad, he became sub-director of the museum in 1937, and replaced Louis Roule (1861–1942) as the chairperson of herpetology and ichthyology. He published over 600 scientific books and articles and discovered around 350 new species. He named a number of fishes from the family Cichlidae, such as the genera '' Astatoreochromis'', '' Astatotilapia'', '' Boulengerochromis'', ''Lepidiolamprologus'', ''Nanochromis'' and '' Ophthalmotilapia''. Taxa named in his honor He has the following species named in his honor: * The Clingfish '' Apletodon pellegrini'' * ''Enteromius pelle ...

Bagrus Docmak
''Bagrus'' is a genus of bagrid catfishes. These are relatively large catfish found in freshwater habitats in Africa, except for the virtually unknown ''B. tucumanus'' from South America, which likely is a synonym of '' Luciopimelodus pati''. Taxonomy The present scientific name ''Bagrus'' was first proposed by Louis Augustin Guillaume Bosc in 1816 for the bayad and its closest relatives. Although in 1809, Geoffroy Saint-Hilaire had already separated this fish in his new genus ''Porcus''. But this was overruled by the ICZN, so that the junior synonym could continue to be used.Ferraris (2007) Species Eleven living species are placed here: * ''Bagrus bajad'' ( Forsskål, 1775) (Bayad) * ''Bagrus caeruleus'' T.

Danios
''Danio'' is a genus of small freshwater fish in the family Cyprinidae found in South and Southeast Asia, commonly kept in aquaria. They are generally characterised by a pattern of horizontal stripes, rows of spots or vertical bars. Some species have two pairs of long barbels. Species of this genus consume various small aquatic insects, crustaceans and worms. Taxonomy The name ''"danio"'' comes from the Bangla name ''dhani'', meaning "of the rice field". ''Danio'' was described in the early 19th century by Francis Hamilton. Two of the species included by him in the genus, still remain valid—''D. dangila'' and ''D. rerio''. About a century later (1916) and with many more species described in the meantime, the genus was split; the larger species into ''Danio'' and the smaller species into the genus ''Brachydanio''.Spence, R., Gerlach, G., Lawrence, C. & Smith, C.

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'' and Lake Tanganyika sprat, ''Stolothrissa tanganicae''), both of which are small, planktivorous, pelagic, freshwater clupeid originating from Lake Tanganyika in Zambia. They form the major biomass of pelagic fish in Lake Tanganyika and Lake Malawi, swimming in large schools in the open lake, feeding on copepods and potentially jellyfish. Their major predators are four species of ''Lates'' which are also endemic to Lake Tanganyika, and are related to (but not the same as) the Nile perch in Lake Victoria. All of these pelagic fish have suffered from overfishing in the last two decades. ''Limnothrissa miodon'' has been successfully introduced in both natural and artificial African lakes. Large kapenta fisheries now take place in the Lake ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Meal Of Omena, Vegetables And Ugali
A meal is an eating occasion that takes place at a certain time and includes consumption of food. The names used for specific meals in English vary, depending on the speaker's culture, the time of day, or the size of the meal. Although they can be eaten anywhere, meals typically take place in homes, restaurants, and cafeterias. Regular meals occur on a daily basis, typically several times a day. Special meals are usually held in conjunction with such occasions as birthdays, weddings, anniversaries, and holidays. A meal is different from a snack in that meals are generally larger, more varied, and more filling than snacks. The type of food that is served or consumed at any given time depends on regional customs. Three main meals are often eaten in the morning, early afternoon, and evening in most modern civilizations. Further, the names of meals are often interchangeable by custom as well. Some serve dinner as the main meal at midday, with supper as the late afternoon/early e ...

Selling Omena
Sales are activities related to selling or the number of goods sold in a given targeted time period. The delivery of a service for a cost is also considered a sale. The seller, or the provider of the goods or services, completes a sale in response to an acquisition, appropriation, requisition, or a direct interaction with the ''buyer'' at the point of sale. There is a passing of title (property or ownership) of the item, and the settlement of a price, in which agreement is reached on a price for which transfer of ownership of the item will occur. The ''seller'', not the purchaser, typically executes the sale and it may be completed prior to the obligation of payment. In the case of indirect interaction, a person who sells goods or service on behalf of the owner is known as a salesman or saleswoman or salesperson, but this often refers to someone selling goods in a store/shop, in which case other terms are also common, including '' salesclerk'', ''shop assistant'', and ' ...

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 ...

Haplochromine
__NOTOC__ The haplochromine cichlids are a tribe of cichlids in subfamily Pseudocrenilabrinae called Haplochromini. This group includes the type genus (''Haplochromis'') plus a number of closely related genera such as '' Aulonocara'', '' Astatotilapia'', and '' Chilotilapia''. They are endemic to eastern, southern and northern Africa, except for ''Astatotilapia flaviijosephi'' in the ''Middle East''. A common name in a scientific context is East African cichlids – while they are not restricted to that region, they are the dominant Cichlidae there. This tribe was extensively studied by Ethelwynn Trewavas, who made major reviews in 1935 and 1989, at the beginning and at the end of her career in ichthyology. Even today, numerous new species are being described each year. The haplochromines were in older times treated as subfamily Haplochrominae, However, the great African radiation of pseudocrenilabrine cichlids is certainly not monophyletic without them, and thus they are t ...

Oreochromis Niloticus
The Nile tilapia (''Oreochromis niloticus'') is a species of tilapia, a cichlid fish native to the northern half of Africa and the Levante area, including Land of Israel, Israel, and Lebanon. Numerous Introduced species, introduced populations exist outside its natural range. It is also commercially known as mango fish, nilotica, or boulti. The first name leads to easy confusion with another tilapia which is traded commercially, the mango tilapia (''Sarotherodon galilaeus''). Description The Nile tilapia reaches up to in length, and can exceed . As typical of tilapia, males reach a larger size and grow faster than females. Wild type, Wild, natural-type Nile tilapias are brownish or grayish overall, often with indistinct banding on their body, and the tail is vertically striped. When breeding, males become reddish, especially on their fins. Although commonly confused with the blue tilapia (''O. aureus''), that species lacks the striped tail pattern, has a red edge to the dorsal f ...

Lates Niloticus
The Nile perch (''Lates niloticus''), also known as the African snook, Goliath perch, African barramundi , Goliath barramundi, Giant lates or the Victoria perch, is a species of freshwater fish in family Latidae of order Perciformes. It is widespread throughout much of the Afrotropical realm, being native to the Congo, Nile, Senegal, Niger and Lake Chad, Volta, Lake Turkana, and other river basins. It also occurs in the brackish waters of Lake Maryut in Egypt. The Nile perch is a fish of substantial economic and food-security importance in East Africa. Originally described as ''Labrus niloticus,'' among the marine wrasses, the species has also been referred to as ''Centropomus niloticus''. Common names include African snook, Victoria perch (a misleading trade name, as the species is not native to Lake Victoria, though they have been introduced there), and many local names in various African languages, such as the Luo name ''mbuta'' or ''mputa''. In Tanzania, it is called ''sa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Corixidae
Corixidae is a family of aquatic insects in the order Hemiptera. They are found worldwide in virtually any freshwater habitat and a few species live in saline water. There are about 500 known species worldwide, in 55 genera, including the genus '' Sigara''. Members of the Corixidae are commonly known as water boatmen, a term that is sometimes used in the United Kingdom for ''Notonecta glauca'', an insect of a different family, Notonectidae. ''Corixa punctata'' is the "lesser water boatman". Morphology and ecology Corixidae generally have a long flattened body ranging from long. Many have extremely fine dark brown or black striations marking the wings. They tend to have four long rear legs and two short front ones. The forelegs are covered with hairs and shaped like oars, hence the name "water boatman". Their four hindmost legs have scoop- or oar-shaped tarsi to aid swimming. They also have a triangular head with short, triangular mouthparts. Corixidae dwell in slow rivers and p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chironomid
The Chironomidae (informally known as chironomids, nonbiting midges, or lake flies) comprise a family of nematoceran flies with a global distribution. They are closely related to the Ceratopogonidae, Simuliidae, and Thaumaleidae. Many species superficially resemble mosquitoes, but they lack the wing scales and elongated mouthparts of the Culicidae. The name Chironomidae stems from the Ancient Greek word ''kheironómos'', "a pantomimist". Common names and biodiversity This is a large taxon of insects; some estimates of the species numbers suggest well over 10,000 world-wide. Males are easily recognized by their plumose antennae. Adults are known by a variety of vague and inconsistent common names, largely by confusion with other insects. For example, chironomids are known as "lake flies" in parts of Canada and Lake Winnebago, Wisconsin, but "bay flies" in the areas near the bay of Green Bay, Wisconsin. They are called "sand flies", "muckleheads", "muffleheads", "Canadian so ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
