Die Zambezikurper (Pharyngochromis acuticeps) is 'n varswatervis wat voorkom in die Zambezi-, Okavango- en boonste gedeelte van die Saverivier-stelsels. In Engels staan die vis bekend as die Zambezi river bream.

Voorkoms

Die vis is bruin met swart vertikale bane oor die lyf en helder groen skakerings. Die skubbe op die lyf is donker rooi in die middel met oranje-rooi rante. Daar is bruin kolle op die stertvin en die analevin het 'n oranje rant met helder oranje kolle op. Die vis word tot 220 mm lank.

Habitat

Die vis word in 'n groot verskeidenheid habitatte aangetref waar daar gewoonlik beskerming is soos plante of boomwortels. Hulle vreet insekte, vissies en eiers en larwes van ander vissies. Hulle is weer die slagoffers van kormorante. Die wyfie is 'n mondbroeier en lê haar eiers in die somer.

Pharyngochromis acuticeps ( allemand )

fourni par wikipedia DE

Pharyngochromis acuticeps (Syn.: Chromis acuticeps, Haplochromis multiocellatus[1]) ist eine Buntbarschart, die im oberen und mittleren Stromgebiet von Sambesi und Cuanza, in dem des Okavango, im Kafue, im Save und in der Kariba-Talsperre vorkommt.

Merkmale

Pharyngochromis acuticeps wird 12 bis 22 cm lang und hat eine bullige Buntbarschgestalt mit großem Kopf und Maul. Das Kopfprofil ist gerade bis leicht gebogen. Die Schwanzflosse ist abgerundet. Die Fische sind bräunlich mit dunklen Querbändern auf den Körperseiten. Die Zentren der Schuppen sind rötlich. Die untere Körperhälfte der Männchen glänzt grünlich. Ihre Afterflosse ist orange gesäumt. Sie zeigt einige gelbe Eiflecke. Bei den Männchen ist der hintere Bereich der Rückenflosse und der vordere Abschnitt der Schwanzflosse rötlichbraun gepunktet.

Lebensweise

Pharyngochromis acuticeps kommt in unterschiedlichen Gewässern vor, meidet aber kleine Gewässern, und scheint recht anpassungsfähig zu sein. Die Art ernährt sich vor allem von Insekten und Krebstieren, sowie von kleineren Fischen und Fischeiern. Wie alle Haplochromis-Verwandten ist sie ein Maulbrüter. Bei Pharyngochromis acuticeps übernimmt das Weibchen die Maulbrutpflege.

Zambezi bream ( anglais )

fourni par wikipedia EN

Zambezi bream (Pharyngochromis acuticeps), also known as dwarf bream, is a species of haplochromine cichlid which is found in river systems in southern Africa.

Description

The Zambezi bream is a medium-sized species of haplochromine which has a large head with a rounded snout and an slightly, upward pointing mouth. It has a slender body with a relatively straight outline, a long dorsal fin and a truncated caudal fin. The dorsal fin contains 14-16 spines and 10-13 soft rays while the anal fin has 2 spines and 7-10 soft rays. The lateral line is in two sections and contains 36 scales. The body is brown in colour on the upperside which his marked by darker brown bars, with the colour becoming iridescent green towards the belly. The scales have red in their centres and there are red dots on the parts of the dorsal and anal fins supported by rays, while the tail has brown spots and there are orange egg imitating spots on the anal fin.[3] They grow to a total length of 12 centimetres (4.7 in).[2]

Distribution

The Zambezi bream is found in the upper and middle catchments of the Zambezi River system in Zambia, Zimbabwe and Namibia, in the upper Save River and upper Runde River in Zimbabwe and in the Chobe River, Okavango River and Cunene River in Botswana, Namibia and Angola.[3] A population in the Mwekera, a tributary of the Kafue River may represent a separate species.[1] Although some sources state that it is absent in the Cunene.[4]

Habitat and biology

The Zambezi bream is found in the margins of river channels and tributaries where there is a slower current as well as in lagoons and floodplains dominated by sawgrass, wherever there is an abundance of aquatic plants or tangles of tree roots. They are predators which feed on molluscs especially snails and freshwater mussels, as well as freshwater crustaceans and insect larvae and the eggs and fry of other fishes. It is preyed on by cormorants and African darters and also by subsistence fishermen. Spawning takes place in the summer and the female takes a brood of 800 eggs into her mouth after spawning, she also mouthbroods the fry. They have a lifespan of 3–4 years.[3] This species is possibly an important intermediate host of the parasitic nematodes of the genus Contracaecum, the ultimate hosts being the piscivorous birds which frequently feed on Zambezi bream including white-breasted cormorant, long-tailed cormorant, African darter and grey heron.[5]

Pharyngochromis acuticeps, também conhecido como dourada -tral.

Descrição

Esta espécie da bacia do Zambeze é uma espécie de haplochromine de tamanho médio que tem uma cabeça grande com um focinho arredondado e uma boca ligeiramente para cima. Tem um corpo esguio com um contorno relativamente recto, uma barbatana dorsal longa e uma barbatana caudal truncada. A barbatana dorsal contém 14-16 espinhos e 10-13 raios moles, enquanto a barbatana caudal tem 2 espinhos e 7-10 raios moles. A linha lateral está em duas secções e contém 36 escamas. O corpo é de cor marrom na parte superior que é marcado por barras marrons mais escuras, com a cor tornando-se verde iridescente em direção à barriga. As escamas são vermelhas nos seus centros e há pontos vermelhos nas partes das barbatanas dorsais e caudais apoiadas por raios, enquanto a cauda tem manchas marrons e há pontos de imitação de ovos alaranjados na nadadeira caudal.[2] Eles crescem até um comprimento total de 12 centímetros (4,7 in).[3]

Distribuição

A espécie do Zambeze encontra-se nas bacias do rio Zambeze na Zâmbia, Zimbabué e Namíbia, no alto Rio Save e no alto rio Runde no Zimbabué e no rio Chobe, rio Okavango e rio Cunene no Botsuana, Namíbia e Angola.[2] Uma população no Mwekera, um afluente do rio Kafue, pode representar uma espécie separada,[1] apesar de algumas fontes afirmarem que está ausente no Cunene.[4]

Habitat e biologia

A espécie do Zambeze encontra-se nas margens dos canais fluviais e afluentes, onde existe uma corrente mais lenta, bem como em lagoas e planícies aluviais dominadas por serapilheira, onde haja abundância de plantas aquáticas ou emaranhados de raízes de árvores. São predadores que se alimentam de moluscos, especialmente caracóis e mexilhões de água doce, bem como crustáceos de água doce e larvas de insectos e ovos e de outros peixes. É caçado por corvos marinhos e africanos e também por pescadores de subsistência. A desova ocorre no verão e a fêmea leva uma ninhada de 800 ovos em sua boca após a desova; ela também pode matar os filhotes. Têm uma vida útil de 3-4 anos.[2] Esta espécie é possivelmente um hospedeiro intermediário importante dos nematoides parasitas do género Contracaecum, sendo os hospedeiros finais os pássaros piscívoros que frequentemente se alimentam desta espécie do Zambeze, incluindo o cormorão-de-peito-branco, o cormorão de cauda longa, o darter africano e a garça cinzenta.[5]
