Hydrocynus
''Hydrocynus'' is a genus of large characin fish in the family Alestidae commonly called "tigerfish," native to the African continent. The genus name is derived from Ancient Greek ὕδωρ ("water"Liddell, H.G. & Scott, R. (1940). ''A Greek-English Lexicon. revised and augmented throughout by Sir Henry Stuart Jones. with the assistance of. Roderick McKenzie.'' Oxford: Clarendon Press.) + κύων ("dog"). (In fact, this fish is popularly referred to as ''poisson chien'' (dog fish) in French-speaking West Africa.) The genus contains five species, all popularly known as "African tigerfish" for their fierce predatory behaviour and other characteristics that make them excellent game fish. ''Hydrocynus'' are normally piscivorous, but ''H. vittatus'' is the only freshwater fish proven to prey on birds in flight.

Hydrocynus Forskahlii
''Hydrocynus forskahlii'', the elongate tigerfish, is a species of predatory characin from the family Alestidae which is found in northern and western Africa. Description ''Hydrocynus forskahlii'' has pronounced stripes along the length of the body. There are two scales between the pelvic fin insertion and the lateral line, less than for other species of tigerfish such as ''Hydrocynus brevis'' which has 23-5 scales in the same position. The lateral line scale count is between 46 and 53 scales and the anal fin ray count is 3 soft, unbranched rays with 11-14 branched rays. It is a slenderer species than other Hydrocynus and the depth of the body averages 22.6 per cent of its length and the head averages around 20 per cent of the body length. It has 9 to 14 teeth in the upper jaw and 8 to 12 in the lower jaw and the jaws are frequently short and upturned. They are similar in colour and pattern to ''Hydrocynus vittatus'' being bright, silvery white in color, but with a grayish tail tha ...

Hydrocynus Vittatus
''Hydrocynus vittatus'', the African tigerfish, tiervis or ngwesh is a predatory freshwater fish distributed throughout much of Africa. This fish is generally a piscivore but it has been observed leaping out of the water and catching barn swallows in flight. Includes a video. Includes a video. Appearance The African tigerfish is overall silvery in colour, with thin black stripes running horizontally. It has an elongated body and a red, forked caudal fin with a black edge. Its head is large, as well as its teeth, of which there are eight per jaw. The teeth are sharp and conical which are used to grasp and chop prey. They are able to replace their teeth simultaneously on the upper and lower jaws. Males are larger and more full-bodied than females. It grows to a length of SL.

Hydrocynus Goliath
''Hydrocynus goliath'', also known as the goliath tigerfish, giant tigerfish, or mbenga, is a very large African predatory freshwater fish of the family Alestidae. Distribution ''Hydrocynus goliath'' is found in the Congo River Basin (including Lualaba River and Lake Upemba), and Lake Tanganyika. A study published in 2011 revealed several mtDNA clades in this region, suggesting a higher tigerfish species richness than traditionally recognized. If confirmed, this would restrict ''H. goliath'' to the Congo River Basin.Goodier, S.A.M., F.P.D. Cotterill, C. O'Ryan, P.H. Skelton, and M.J de Wit (2011).

Hydrocynus Brevis
''Hydrocynus brevis'', also known as the tigerfish, Nile tigerfish or Sahelian tigerfish, is a predatory freshwater fish distributed throughout Africa. Appearance The tigerfish is silver in colour when young, with thin black horizontal stripes and an elongated body that tapers at both ends. As the fish grows, it will develop a bronze coloration and the stripes will fade. The ventral and caudal fins have a slight red-orange tint, and the adipose fin is grey to black. It grows to a length of SL."Hydrocynus Brevis (Gunther, 1864)." FishBase. N.p., n.d. Web. 22 Dec. 2013. Distribution This species has a wide distribution. It is found from Senegal to Ethiopia, throughout the Nile. In Northeast Africa it is found in the Ghazal and Jebel systems, Sudan, as well as Baro River, Ethiopia. In Western Africa it is known from Chad, Niger/Bénoué, Volta, Senegal and Gambia. Habitat and ecology A demersal, potamodromous freshwater species, ''Hydrocynus brevis'' prefers open-water habita ...

Hydrocynus Tanzaniae
''Hydrocynus tanzaniae'', the blue tigerfish, is a large African predatory freshwater fish. Distribution The eastward flowing rivers of Tanzania and in the Ruaha and Rufiji river systems.http://biostor.org/reference/32 page 201 Description ''Hydrocynus tanzaniae'' is a large, predatory fish. It has pronounced dentition similar to those found in ''Hydrocynus forskahlii''. The holotype was nine and a half inches long (247mm), but specimens have been caught by fishermen greater than 27 inches (70 cm) and 25 pounds (11 kg). At a given length, H. tanzaniae has a deeper body than either ''H. forskahlii'' or '' H. vittatus''.http://biostor.org/reference/32 page 199 These fish are a silvery grey color and often have pronounced stripes. They often have markings in blue, black, pink, green and red, making them among the more colorful of African tiger fish. Uniquely among the African tiger fish, they have a blue adipose fin Fins are distinctive anatomical features comp ...

Tigerfish
Tigerfish can refer to fish from various families, and derives from official and colloquial associations of these with the tiger (''Panthera tigris''). However, the primary species designated by the name "tigerfish" are African and belong to the family Alestidae. African tigerfish Several species belonging to the genus '' Hydrocynus'' of the family Alestidae are referred to as "tigerfish", and are particularly prized as game fish. These African fish are found in many rivers and lakes on the continent and are fierce predators with distinctive, proportionally large teeth. The goliath tigerfish (''Hydrocynus goliath'') is among the most famous tigerfish. The largest one on record is said to have weighed . It is found in the Congo River system and Lake Tanganyika and is the largest member of the family Alestidae. Another famous species, simply called the tigerfish (''Hydrocynus vittatus''), is commonly found in the southernly Okavango Delta, and the Zambezi River, and also in the ...

Characiformes Genera
Characiformes is an order of Actinopterygii, ray-finned fish, comprising the characins and their allies. Grouped in 18 recognized families, more than 2000 different species are described, including the well-known piranha and tetras.; Buckup P.A.: "Relationships of the Characidiinae and phylogeny of characiform fishes (Teleostei: Ostariophysi)", ''Phylogeny and Classification of Neotropical Fishes'', L.R. Malabarba, R.E. Reis, R.P. Vari, Z.M. Lucena, eds. (Porto Alegre: Edipucr) 1998:123-144. Taxonomy The Characiformes form part of a series called the Ostariophysi, Otophysi within the superorder Ostariophysi. The Otophysi contain three other orders, Cypriniformes, Siluriformes, and Gymnotiformes. The Characiformes form a group known as the Characiphysi with the Siluriformes and Gymnotiformes. The order Characiformes is the sister group to the orders Siluriformes and Gymnotiformes, though this has been debated in light of recent molecular evidence. Originally, the characins were ...

Freshwater Fish Genera
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. ...
