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).]]> Wed 12 May 2021 22:23:17 SAST ]]> Establishment of translocated populations of smallmouth yellowfish, Labeobarbus aeneus (Pisces: Cyprinidae), in lentic and lotic habitats in the Great Fish River system, South Africa https://vital.seals.ac.za/vital/access/manager/Repository/vital:35607 Wed 12 May 2021 20:59:23 SAST ]]> A comparison of three techniques for fluorochrome marking of juvenile Clarias gariepinus otoliths https://vital.seals.ac.za/vital/access/manager/Repository/vital:35450 Wed 12 May 2021 20:55:58 SAST ]]> An assessment of a light-attraction fishery in southern Lake Malawi https://vital.seals.ac.za/vital/access/manager/Repository/vital:35472 Wed 12 May 2021 19:11:37 SAST ]]> Growth, reproduction and population structure of Diplotaxodon limnothrissa in the southeast arm of Lake Malawi https://vital.seals.ac.za/vital/access/manager/Repository/vital:35633 Wed 12 May 2021 18:32:19 SAST ]]> Estimating δ15N fractionation and adjusting the lipid correction equation using Southern African freshwater fishes https://vital.seals.ac.za/vital/access/manager/Repository/vital:29392 Tue 31 Aug 2021 11:49:55 SAST ]]> Comparing the fish assemblages and food web structures of large floodplain rivers https://vital.seals.ac.za/vital/access/manager/Repository/vital:29343 Tue 31 Aug 2021 11:49:53 SAST ]]> The abundance of an invasive freshwater snail Tarebia granifera (Lamarck, 1822) in the Nseleni River, South Africa https://vital.seals.ac.za/vital/access/manager/Repository/vital:29382 Tue 15 Aug 2023 11:44:27 SAST ]]> Life history and population dynamics of invasive common carp, Cyprinus carpio, within a large turbid African impoundment https://vital.seals.ac.za/vital/access/manager/Repository/vital:35708 Thu 29 Jul 2021 16:22:45 SAST ]]> Life history strategy and population characteristics of an unexploited riverine cyprinid, Labeo capensis, in the largest impoundment in the Orange River Basin https://vital.seals.ac.za/vital/access/manager/Repository/vital:35709 Thu 29 Jul 2021 16:22:44 SAST ]]> Life-history characteristics of an age-validated established invasive African sharptooth catfish, Clarias gariepinus, population in a warm–temperate African impoundment https://vital.seals.ac.za/vital/access/manager/Repository/vital:35710 Thu 29 Jul 2021 16:22:44 SAST ]]> Quantifying the annual fish harvest from South Africa’s largest freshwater reservoir https://vital.seals.ac.za/vital/access/manager/Repository/vital:7149 Thu 29 Jul 2021 16:22:43 SAST ]]> Who uses the fishery resources in South Africa’s largest impoundment?
