It is eurythermic (80–35°C), mesohalic (0–10 ppt) and has the ability to airbreathe. These attributes predispose it to surviving in all but the most adverse of conditions and have directly contributed to its wide use as an aquaculture species. These attributes have also contributed to its ability to invade waterbodies beyond its natural range (de Moor & Bruton 1988) and after inadvertent introductions such as by escape from aquaculture facilities or through water transfer schemes, C. gariepinus has established populations in many non-native environments. Such invasions include the Philippines (Mercene 1997), Bangladesh (Arthur & Ahmed 2002), Thailand (Vidthayanon 2005), India (Bhakta & Bandyopadhyay 2007) and Brazil (Cambray 2005; Vitule et al. 2006; Rocha & Schiavetti 2007). In South Africa, C. gariepinus invaded the temperate Great Fish River catchment after the species was translocated from the Orange River through a Interbasin Water Transfer (IBWT) scheme (Laurenson et al. 1989). Potential threats include predation of and competition with indigenous species, habitat degradation, and the spread of diseases and parasites (Dudgeon et al. 2006).]]> Mon 13 May 2024 14:51:09 SAST ]]> A histological description of ovarian recrudescence in two Labeo victorianus populations https://commons.ru.ac.za/vital/access/manager/Repository/vital:35455 Mon 13 May 2024 14:50:46 SAST ]]> Effect of turbidity on the foraging success of Glossogobius callidus (Teleostei: Gobiidae) https://commons.ru.ac.za/vital/access/manager/Repository/vital:35600 Mon 13 May 2024 14:49:43 SAST ]]> The largest volcanic eruptions on Earth https://commons.ru.ac.za/vital/access/manager/Repository/vital:36902 1000 km3 dense rock equivalent) and large-magnitude (> M8) eruptions produce really extensive (104–105 km2) basaltic lava flow fields and silicic ignimbrites that are the main building blocks of LIPs.]]> Mon 13 May 2024 12:06:03 SAST ]]> The geochemistry and evolution of Palaeogene phonolites, central Namibia: https://commons.ru.ac.za/vital/access/manager/Repository/vital:38399 Mon 13 May 2024 12:05:37 SAST ]]> Cretaceous volcanic rocks of the Namibe Basin, southern Angola: report on a reconnaissance field and geochemical investigation https://commons.ru.ac.za/vital/access/manager/Repository/vital:29070 Mon 13 May 2024 12:05:14 SAST ]]> Sedimentary facies and geomorphic evolution of a blocked‐valley lake: Lake Futululu, northern Kwazulu‐Natal, South Africa https://commons.ru.ac.za/vital/access/manager/Repository/vital:35928 Mon 13 May 2024 09:23:47 SAST ]]> Human impacts on hydrological health and the provision of ecosystemservices: a case study of the eMthonjeni–Fairview Spring Wetland, Grahamstown, South Africa https://commons.ru.ac.za/vital/access/manager/Repository/vital:38337 Mon 13 May 2024 09:22:43 SAST ]]> Assessment of the environmental condition, Ecosystem service provision and sustainability of use of two wetlands in the Kamiesberg uplands: https://commons.ru.ac.za/vital/access/manager/Repository/vital:40089 Mon 13 May 2024 09:20:08 SAST ]]> A framework for recuperation: HIV/AIDS and the Keiskamma Altarpiece https://commons.ru.ac.za/vital/access/manager/Repository/vital:38652 Mon 13 May 2024 08:51:13 SAST ]]> The use of learning support materials in rural schools of Maputaland, KwaZulu-Natal, South Africa https://commons.ru.ac.za/vital/access/manager/Repository/vital:68186 Mon 02 Oct 2023 08:12:56 SAST ]]> Bandwidth management and monitoring for community networks https://commons.ru.ac.za/vital/access/manager/Repository/vital:72482 Fri 17 May 2024 12:34:56 SAST ]]> The use and appreciation of botanical gardens as urban green spaces in South Africa https://commons.ru.ac.za/vital/access/manager/Repository/vital:43702 Fri 10 May 2024 15:23:40 SAST ]]> Production of and trade in African indigenous vegetables in the urban and peri-urban areas of Durban, South Africa https://commons.ru.ac.za/vital/access/manager/Repository/vital:43701 Fri 10 May 2024 15:21:43 SAST ]]> 'Rich man poor man': inter-household and community factors influencing the use of wild plant resources amongst rural households in South Africa https://commons.ru.ac.za/vital/access/manager/Repository/vital:37953 Fri 10 May 2024 15:20:58 SAST ]]>
