Ndagala

Last updated

Ndagala ( Burundi ) or Daaga ( Tanzania ) are the vernacular names given to two species of small pelagic fish of the Clupeidae family (which also includes Sardines and Shads), which are only found in Lake Tanganyika. [1]

Limnothrissa miodon is a large species, typically 10–12 centimetres (3.9–4.7 in) long, zooplanktonophagous, with a coastal pelagic character. It lives for about two years. It is called “Lumpu” in Burundi and Isambaza in Rwanda. Stolothrissa tanganicae is a small species, typically 6–8 centimetres (2.4–3.1 in) long, planktivorous, called Ndagala in the Swahili language, and living further offshore. It lives for one to one and a half years. [1]

Although technically fishing of the two species is banned, in practice it continues. [1] The Ndagala are caught all year round, and are an important part of the local people's diet. [2]

Bujumbura, formerly Usumbura, is the economic capital, largest city and main port of Burundi. It ships most of the country's chief export, coffee, as well as cotton and tin ore. Bujumbura was formerly the country's political capital. In late December 2018, Burundian president Pierre Nkurunziza announced that he would follow through on a 2007 promise to return Gitega its former political capital status, with Bujumbura remaining as economical capital and center of commerce. A vote in the Parliament of Burundi made the change official on 16 January 2019, with all branches of government expected to move to Gitega within three years.

Lake Tanganyika is an African Great Lake. It is the second-largest freshwater lake by volume and the second deepest, in both 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, Burundi, and Zambia—with Tanzania (46%) and the DRC (40%) possessing the majority of the lake. It drains into the Congo River system and ultimately into the Atlantic Ocean.

The pelagic cormorant, also known as Baird's cormorant or violet-green cormorant, is a small member of the cormorant family Phalacrocoracidae. Analogous to other smallish cormorants, it is also called the pelagic shag occasionally. This seabird lives along the coasts of the northern Pacific; during winter it can also be found in the open ocean. Pelagic cormorants have relatively short wings due to their need for economical movement underwater, and consequently have the highest flight costs of any bird.

Lake Kivu is one of the African Great Lakes. It lies on the border between the Democratic Republic of the Congo and Rwanda, and is in the Albertine Rift, the western branch of the East African Rift. Lake Kivu empties into the Ruzizi River, which flows southwards into Lake Tanganyika. In 1894, German explorer and officer Gustav Adolf von Götzen was the first European to discover the lake.

<span class="mw-page-title-main">African Great Lakes</span> Series of lakes in the Rift Valley

The African Great Lakes are a series of lakes constituting the part of the Rift Valley lakes in and around the East African Rift. The series includes Lake Victoria, the second-largest freshwater lake in the world by area; Lake Tanganyika, the world's second-largest freshwater lake by volume and depth; Lake Malawi, the world's eighth-largest freshwater lake by area; and Lake Turkana, the world's largest permanent desert lake and the world's largest alkaline lake. Collectively, they contain 31,000 km3 (7,400 cu mi) of water, which is more than either Lake Baikal or the North American Great Lakes. This total constitutes about 25% of the planet's unfrozen surface fresh water. The large rift lakes of Africa are the ancient home of great biodiversity, and 10% of the world's fish species live in this region.

The Tanganyika sardine is a term for two related species, 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 the Nile perch in Lake Victoria. All of these pelagic fish have suffered from overfishing in the last two decades.

In late December 2018, Burundian president Pierre Nkurunziza announced that he would follow on a 2007 promise to return Gitega its former political capital status, with Bujumbura remaining as economic capital and centre of commerce.

The Ruzizi is a river, 117 kilometres (73 mi) long, that flows from Lake Kivu to Lake Tanganyika in Central Africa, descending from about 1,500 metres (4,900 ft) to about 770 metres (2,530 ft) above sea level over its length. The steepest gradients occur over the first 40 kilometres (25 mi), where hydroelectric dams have been built. Further downstream, the Ruzizi Plain, the floor of the Western Rift Valley, has gentle hills, and the river flows into Lake Tanganyika through a delta, with one or two small channels splitting off from the main channel.

The wildlife of Burundi is composed of its flora and fauna. The small, landlocked country is home to 2,950 species of plants, 596 birds, 163 species of mammals, 52 species of reptiles, 56 species of amphibians, and 215 fish species. The wildlife has been drastically reduced in recent years, mainly on account of intense population pressure, conversion of large areas of forest into agricultural land, and extensive livestock farming. The protected area encompasses little more than 5% of the total area of the country.

The species name is a Latinized combination of the Latin "grandi", meaning large or big, and the Greek "ops", meaning eye, a reference to the relatively large eyes of this fish.
