Impacts of Moringa oleifera leaves and Lannea barteri bark as growth promoting additives and survival rates in the diets of Clarias gariepinus fingerlings.
An experiment was conducted to determine the effects of plant additives as fish growth promoter and survival rate in the diets of clariid fish species. 540 Clarias gariepinus fingerlings of average initial weight of 4.6 Â± 0.02 were distributed into 27 re-circulatory tanks of 50 L capacity filled with 20 L volume of water. The fish were distributed in replicate representing nine (9) dietary treatments in a complete randomised design. The diets comprised of Non Additive Diet (NAD), Moringa Whole (MWL), Moringa Aqueous Extract (MAE), Moringa Ethanol Extract (MEE), Lannea barteri Whole (LWL), Lannea barteri Aqueous Extract (LAE), Lannea barteri Ethanol Extract (LEE), Antibiotic (ANTB) and a Commercial Reference Feed (Coppens) (CRD) as control diet. The experiment revealed that, the survival rate ranges between 90 and 98% in which the highest (P<0.05) survival rates were recorded in the group of fish that were fed plant additives. The growth parameter shows significance difference (P<0.05) between the control and experimental diets. There were no significance differences (P>0.05) among CRD, NAD and ANTB in their growth parameters. Among the plant additives-based diets, best growth was recorded in LWL based diet (9.077 Â± 0.58). However, there were no significant differences (P>0.05) among CRD, NAD and ANTB in the SGR values (2.46 Â± 0.21, 2.48 Â± 0.17 and 2.23 Â± 0.23) respectively. There was no significant different (P>0.05) for feed conversion ratio while the protein efficiency ratio values in CRD, NAD, and ANTB were significantly higher (P<0.05) than MWL, MAE, MEE, LWL LAE, LEE respectively. The highest (P<0.05) Apparent Net Protein
Utilization (ANPU) was recorded in LEE (98.33 Â± 2.89) based diet while ANTB (5.57 Â± 1.92) had a significantly (P<0.05) low ANPU. From the research, Lannea barteri whole incorporation (LWL) had the best impact on the Catfish followed by non-additive diet in terms of growth and compositions of the fish without any negative impact.
