Abstract

The growth performance and survivability enhancement potential of some medicinal plant feed additives for combatting Pseudomonad infections in Clarias gariepinus were evaluated. Three medicinal plants (5 g/kg Allium sativum, 10 g/kg Chromolaena odorata and 10 g/kg Talinum triangulare) were incorporated separately into a basic diet. Juvenile Clarias gariepinus (n = 150, 53.05 � 0.23 g), randomised into four groups, were fed for 42 days. The control group was fed with a non-supplemented diet. Growth parameters were determined and thereafter ten fish from each group, randomly selected, were inoculated intraperitoneally with pathogenic Pseudomonas aeruginosa (0.2 mL culture containing 1.4 � 106 cfu/mL). Their survivability was observed for 7 days based on mortality rate and relative level of protection (RLP). Mean weight gains were higher in all treated groups and significantly higher (p < 0.05) in the group of fish fed with 5 g/kg Allium sativum diet compared with the control. The lowest mortality rate (20%) and highest RLP (75) was recorded in the group fed with10 g/kg Chromolaena odorata. The results suggest that medicinal plant feed additives enhanced growth and survival of the cultured Clarias gariepinus. The study recommends 5 g/kg Allium sativum and 10 g/kg Chromolaena odorata diet supplementations as an effective growth promoter and anti-Pseudomonas aeruginosa agent, respectively, for Clarias gariepinus production.
