${session.getAttribute("locale")} 5 Adult African sharptooth catfish, Clarias gariepinus, population dynamics in a small invaded warm-temperate impoundment 150 cm TL, >30 kg; Bruton 1976), long-lived (validated to at least 15 years, Weyl & Booth 2008) and fast-growing (Bruton & Allanson 1980; Quick & Bruton 1984; Richardson et al. 2009) fish that attains sexual maturity within two years of age (de Moor & Bruton 1988). 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 Wed 12 May 2021 20:59:23 SAST ]]> A comparison of three techniques for fluorochrome marking of juvenile Clarias gariepinus otoliths Wed 12 May 2021 20:55:58 SAST ]]> An assessment of a light-attraction fishery in southern Lake Malawi Wed 12 May 2021 19:11:37 SAST ]]> Growth, reproduction and population structure of Diplotaxodon limnothrissa in the southeast arm of Lake Malawi Wed 12 May 2021 18:32:19 SAST ]]> Life history and population dynamics of invasive common carp, Cyprinus carpio, within a large turbid African impoundment 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 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 Thu 29 Jul 2021 16:22:44 SAST ]]> Quantifying the annual fish harvest from South Africa’s largest freshwater reservoir Thu 29 Jul 2021 16:22:43 SAST ]]> Rapid biological assessment of the fishery potential of Xonxa Dam, near Queenstown, South Africa Thu 13 May 2021 08:14:55 SAST ]]> Histological validation of gonadal macroscopic staging criteria for Labeo cylindricus (Pisces: Cyprinidae) Thu 13 May 2021 08:08:28 SAST ]]> On the life history of a cyprinid fish, Labeo cylindricus Thu 13 May 2021 02:33:49 SAST ]]>
