Abstract: Growth of fish is dependent on a wide range of positive or negative impacting factors. Clarias gariepinus has also been introduced into most other countries in Africa, as well as several in Europe, Asia and South America. Methodology A total number of twelve live adult (200â799 g) C. gariepinus comprising 3 each were randomly obtained from two cultured habitats (ponds) and two natural habitats (rivers). From the study so far, it could be deduced that the higher loads of these bacteria are from cultured habitat when compared to natural habitat, this may be attributed to restriction in the movement of water in which C. gariepinus is being reared, and this water restriction encourages the growth of bacteria. endstream endobj 96 0 obj <>stream A total number of 80 live adults (200â799 g) C. gariepinus comprising of 20 each were randomly obtained from two cultured habitats (ponds) and two natural habitats (rivers).
