Hydrocynus goliath, also known as the goliath tigerfish, giant tigerfish, or mbenga, is a very large African predatory freshwater fish of the family Alestidae.

Contents

Distribution

Hydrocynus goliath is found in the Congo River Basin (including Lualaba River and Lake Upemba), and Lake Tanganyika. [3] [4] 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. [5] Four additional species ( H. vittatus and three unknown species) appear to be present in this Basin, while two (H. vittatus and an unknown species) appear to be present in Lake Tanganyika. [5]

This large-toothed, highly predatory fish grows to an average length of 1.5 m (4.9 ft) and a weight of 50 kg (110 lb). [6] Its teeth fit into distinct grooves along its jaws. On average each of its teeth can grow up to 2.5 cm (1 in), [4] according to biologist and television presenter Jeremy Wade. [6] The largest recorded specimen weighed 70 kg (154 lb). [4]

Diet

Hydrocynus goliath is a piscivore, feeding on any fish it can overpower, including smaller members of the same species.

When hunting, this fish uses the calmer eddies of the rapids to ambush its prey, using its keen sight to detect prey. When a target is noticed, the fish accelerates to chase it down. The Nile crocodile is the only known predator of mature goliath tigerfish.

Interaction with humans

A number of incidents have been reported in the Congo of this fish attacking humans. [7] [4] This reputation, combined with its strength, has earned it an almost mythical status among anglers, and it has been called the "greatest freshwater gamefish in the world". [7]

Lake Tanganyika is an African Great Lake. It is the second-oldest freshwater lake in the world, the second-largest by volume, and the second-deepest, in all cases after Lake Baikal in Siberia. It is the world's longest freshwater lake. The lake is shared among four countries—Tanzania, the Democratic Republic of the Congo (DRC), Burundi, and Zambia, with Tanzania (46%) and DRC (40%) possessing the majority of the lake. It drains into the Congo River system and ultimately into the Atlantic Ocean.

Tigerfish can refer to fish from various families, and derives from official and colloquial associations of these with the tiger. However, the primary species designated by the name "tigerfish" are African and belong to the family Alestidae.

<span class="mw-page-title-main">African fish eagle</span> Species of bird

The African fish eagle or the African sea eagle is a large species of eagle found throughout sub-Saharan Africa wherever large bodies of open water with an abundant food supply occur. It is the national bird of Malawi, Namibia, Zambia, and Zimbabwe. As a result of its large range, it is known in many languages. Examples of names include: Vis Arend in Afrikaans, nkwazi in Chewa, aigle pêcheur in French, hungwe in Shona, inkwazi in isiZulu, and ntšhu in Northern Sotho. This species may resemble the bald eagle in appearance; though related, the two species occur on different continents, with the bald eagle being resident in North America.

Hepsetus odoe, the African pike characin, is a predatory freshwater characin belonging to the family Hepsetidae.

Salminus brasiliensis is a large, predatory characiform freshwater fish found in central and east-central South America. Despite having Salminus in its name, the dorado is not related to any species of salmon, nor to the saltwater fish also called dorado. It is very popular among recreational anglers and supports large commercial fisheries.

<i>Hydrocynus</i> 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") + κύων ("dog"). 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 proven to prey on birds in flight.

Serranochromis is a genus of relatively large, robust cichlids from freshwater habitats in mainland Southern Africa, ranging as far north as DR Congo and Tanzania, with the highest species richness in the upper Zambezi, Okavango and Congo basins. They are typically known as largemouths or, especially among fishers, breams. Serranochromis are mostly piscivores and they are important in local fisheries.
