Growth, reproduction and population structure of Diplotaxodon limnothrissa in the southeast arm of Lake Malawi
Item type: Journal Article • Journal: African Journal of Aquatic Science • Authors: GeoffreyZ Kanyerere OlafLF Weyl AnthonyJ BoothDiplotaxodon limnothrissa is a widely distributed species occurring throughout Lake Malawi from the surface to a depth of at least 220m. It is probably the most abundant cichlid in the lake, with biomass estimates of around 87 000t in the... -
Management advice for the Diplotaxodon limnothrissa (Teleostei: Cichlidae) resource in the south-east arm of Lake Malawi, based on per-recruit analysis
Item type: Journal Article • Journal: African Journal of Aquatic Science • Authors: GeoffreyZ Kanyerere AnthonyJ Booth OlafLF WeylDiplotaxodon limnothrissa is a widely distributed species occurring throughout Lake Malawi and is probably the most abundant cichlid in the pelagic zone of the lake. The species is exploited commercially in the south-east arm of the lake, but since the... -
Spatial and temporal variations in densities of small fishes across different temporary floodplain types of the lower Okavango Delta, Botswana
Item type: Journal Article • Journal: African Journal of Aquatic Science • Authors: N Siziba --- , Botswana MJ Chimbari --- , Botswana K Mosepele --- , Botswana H Masundire --- Department of Biological Sciences, BotswanaSmall-sized and juvenile fishes as well as physicochemical water parameters in various primary, secondary and rarely flooded temporary floodplains of the Okavango Delta were assessed during the different hydrological phases of the 2009–2010 flooding season. Small fishes were sampled in... -
Bioaccumulation of metals in Tilapia zillii from Badeni Dam, Côte d'Ivoire
Item type: Journal Article • Journal: African Journal of Aquatic Science • Authors: RB Tate --- Digby Wells Environmental, South Africa A Husted --- Digby Wells Environmental, South AfricaGiven the importance of fish as a source of protein and the potential for exposure of humans to metal elements, metal bioaccumulation concentrations in Tilapia zillii from four sites in the Badeni Dam on the Badeni River, Côte d'Ivoire, were... -
Enigmatic tissue in the orobranchial chamber of cardinalfishes of the genus Siphamia (Perciformes, Apogonidae)
Item type: Journal Article • Journal: African Zoology • Authors: Ofer Gon --- South African Institute for Aquatic Biodiversity, South Africa Shirley C Pinchuck --- Electron Microscopy Unit, South AfricaAn unusual tissue covering the tongue and occasionally part of the gill chamber of many species of the Indo-Pacific cardinalfish genus Siphamia is described and compared with an earlier description of a similar tissue found in the cichlid species Alcolapia... -
Intraspecific morphological divergence in two Cichlid species from Benin
Item type: Journal Article • Journal: African Journal of Aquatic Science • Authors: Luke M Bower --- Program in Ecology and Evolutionary Biology and Department of Wildlife and Fisheries Sciences, USA Laith A Jawad --- Freelance Fish Biodiversity Consultant, New Zealand Pierre M Gnohossou --- Département d’Aménagement et Gestion de Ressources Naturelles, Republic of Benin Ayoko Géraldine Tossou --- Département d’Aménagement et Gestion de Ressources Naturelles, Republic of BeninSelection on morphological traits can vary across the range of species, inducing a mosaic of phenotypes across populations. Intraspecific morphological divergence had been demonstrated for many fish groups inhabiting environments with varying abiotic or biotic selective pressures. Such intraspecific phenotypic... -
New host and distribution records for five species of Enterogyrus Paperna, 1963 (Dactylogyridae: Ancyrocephalinae) from cichlid hosts in South Africa
Item type: Journal Article • Journal: African Journal of Aquatic Science • Authors: Iva Přikrylová --- University of Limpopo, South Africa Sareh Tavakol --- University of Limpopo, South Africa Nico J Smit --- North-West University, South Africa Willem J Smit --- University of Limpopo, South Africa Wilmien J Luus-Powell --- University of Limpopo, South AfricaBetween March 2015 and September 2016, three species of Cichlidae (Coptodon rendalli, Oreochromis mossambicus and Tilapia sparrmanii) were screened for the presence of stomach monogeneans. Four localities across three provinces of South Africa (Limpopo, Northern Cape and North West) were... -
