Hydrocynus
Hydrocynus
Genus of fishes
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"[1]) + κύων ("dog"[1]). (In fact, this fish is popularly referred to as poisson chien (dog fish) in French-speaking West Africa.) The genus contains five species,[2] all popularly known as "African tigerfish" for their fierce predatory behaviour and other characteristics that make them excellent game fish.[3] Hydrocynus are normally piscivorous,[4] but H. vittatus is proven to prey on birds in flight.[5]
