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://vital.seals.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://vital.seals.ac.za/vital/access/manager/Repository/vital:35600 Mon 13 May 2024 14:49:43 SAST ]]>
