Zambezi River Demersal Habitat
(
Anglèis
)
fornì da EOL authors
This taxon is one of a number of demersal species in the Zambezi River system of southern Africa. Demersal river fish are found at the river bottom, feeding on benthos and zooplankton Nutrient levels in the Zambezi River are relatively low, especially in the upper Zambezi; in that reach, above Victoria Falls, most of the catchment drains Kalahari sands, whose nutrient levels are inherently low due to their aeolian formation; moreover, agricultural fertilizer addition throughout the Zambezi watershed is low, due to the shortage of capital available to farmers of this region. Nitrate levels (as nitrogen) in the upper Zambezi are typically in the range of .01 to .03 milligrams per liter. Correspondingly electrical conductivity of the upper Zambezi is on the order of 75 micro-S per centimeter, due to the paucity of ion content. From the Luangwa River downstream nitrate levels elevate to .10 to .18 milligrams per liter, and electrical conductivity rises to a range of two to four times the upper Zambezi levels. Not surprisingly, pH, calcium ion concentration, bicarbonate and electrical conductivity are all higher in portions of the catchment where limestone soils predominate compared to granite. There are a total of 190 fish species present in the Zambezi River, including eel and shark taxa. The largest native demersal species present are the 117 centimeter (cm) long tiger fish (Hydrocynus vittatus), the 175 cm African mottled eel (Anguilla bengalensis labiata), the 120 cm Indonesian shortfin eel (Anguilla bicolor bicolor), the 200 cm Giant mottled eel (Anguilla marmorata), the 150 cm African longfin eel (Anguilla mossambica), the 183 cm Sampa (Heterobranchus longifilis), the 150 cm Cornish jack (Mormyrops anguilloides) and the 700 cm largetooth sawfish (Pristis microdon).
Migration

Catadromous. Migrating from freshwater to the sea to spawn, e.g., European eels. Subdivision of diadromous. Migrations should be cyclical and predictable and cover more than 100 km.

fornì da Fishbase
Migratory species, which breeds in the ocean (Ref. 52331). Inhabits both quiet and fast flowing water (Ref. 13337). Elvers ascend rivers mainly at night and overcome waterfalls and walls of dams with great determination. Adults usually sedentary. Females can attain 120 cm SL and are generally longer and heavier than males (Ref. 48660). Carnivorous, eats dead or living prey but especially fish and crabs. After feeding in fresh water for ten years or more, adults assume a silver breeding dress, the eyes become enlarged and they return to sea to breed. Considered to breed east of Madagascar, but thought to move south of that island on its way to the Mozambique coast and South African rivers (Ref. 13337). Flesh fatty but highly esteemed as smoked or jellied eel (Ref. 5214). Caught with various types of nets (Ref. 4967).

Die Geelbekpaling (Anguilla mossambica) is 'n varswatervis wat voorkom in riviere aan die ooskus van Afrika vanaf Kenia suidwaarts tot by Kaap Agulhas. In Engels staan die vis bekend as die Longfin eel.
Voorkoms
Die kop en lyf is lank en die vel is dik en glad met versonke, klein skubbe. Die dorsale, anale en stertvin is aanmekaar en vorm een vin. Die dorsale vin se oorsprong is voor dié van die anale vin. Die paling het 'n groot mond, klein tandjies en dik lippe. Die kieue is klein en is nét voor die pektorale vinne. Die vis is olyfbruin of grys van kleur (ligter aan die onderkant) en word tot 1.2 m lank. Die Suid-Afrikaanse hengelrekord is 5.73 kg.

African longfin eel
(

fornì da wikipedia EN
The African longfin eel[3] (Anguilla mossambica), also known simply as the longfin eel, is an eel in the family Anguillidae.[4] It was described by Wilhelm Peters in 1852, originally under the genus Muraena.[5] It is a tropical eel known from freshwaters in southern Kenya, Cape Agulhas, Madagascar, and New Caledonia. The eels spend most of their lives in freshwaters far inland, but migrate to the Western Indian Ocean to breed. Males can reach a maximum total length of 150 centimetres; females can reach a maximum standard length of 120 centimetres and a maximum weight of 5,000 grams. The eels can live for about 20 years.[4] Juveniles and adults are known to feed off of carcasses, crabs, and bony fish.[6]
As food
The African longfin eel is raised in commercial fisheries as well as aquafarms, and is also considered a game fish. It has fatty flesh which is prized in a smoked or jellied dish.[4]

Поширення
Цей тропічний вугор поширений у річках Східної Африки. Ареал простягується від Кенії до мису Голковий (ПАР). Вид поширений також на Мадагаскарі та островах Індійського океану.
Опис
В середньому сягає 120 см завдовжки, максимально - 150 см. Максимальна зареєстрована вага - 0,75 кг.[3]
Спосіб життя
Вугрі проводять більшу частину свого життя в прісній воді, воліючи жити між камінням у прозорих, швидких струмках, але мігрують до океану, щоб розмножуватися.[3]
