Comparative Effect of Incorporation Level of Moringa oleifera Leaf Flour on Survival and Growth Performances of Clarias gariepinus and Clarias jaensis Juveniles in Tanks

Abstract

The comparative effect of the level of incorporation of Moringa oleifera leaf flour on the survival and growth characteristics of Clarias gariepinus and Clarias jaensis juveniles was studied between March and June 2017 in Batié (LN: 5° 17'0''-5°18'53''and LE: 10°17'0''- 10°19'31''). The aim of this study was to contribute to the increase in Clarias gariepinus and Clarias jaensis production through the use of local inputs. A total of 320 Clarias gariepinus and Clarias jaensis juveniles (14.23 ± 0.15g) were divided into eight isoprotein treatments (40%) with three replicates. They were fed twice a day for 84 days. The main results were: survival rate was higher in Clarias jaensis (93.33%) with no significant differences recorded. Average final weight, average daily gain and specific growth rate were significantly (P\(\le\)0.05) higher in Clarias gariepinus. Feed conversion was significantly lower in Clarias gariepinus (1.74). Feed cost decreased with increasing incorporation of Moringa oleifera in the feed. The cost of one kg of Clarias gariepinus and Clarias jaensis was significantly lower at 15% for Clarias jaensis (691.44 F CFA). Moringa oleifera can be incorporated into the feed for juveniles of Clarias jaensis at 15% and in Clarias gariepinus at 10%.
