This study was conducted to assess theeffect of dietary inclusions of Lactobacillus plantarum (L. plantarum) andPsidium guajava (P. guajava) diets on the growth performance of Clariasgariepinus (C. gariepinus). Seven treatments were administered to 420 C.gariepinus juveniles. They were: Control (Basal diet of 42% crude protein), L.plantarum (LPc) (cell/1000 mL) at 40, 60, 80 and P. guajava leaf meal (PGLM)(g/1000g) at 40, 60 and 80 per kg of feed. Body Weight Gain (BWG) (g), SpecificGrowth Rate (SGR) (g/day), Feed Conversion Ratio (FCR), Survival Rate (SR) (%),Protein Efficiency Ratio (PER) and Nitrogen Metabolism (NM) were evaluated.Data was analyzed using descriptive statistics and ANOVA at p<0.05. From theresults, 40LPc had the highest body weight gain (73.52±2.30) g and SpecificGrowth Rate (SGR) (1.19±0.02) g/day, while 80 PGLM had the least body weightgain (46.10±0.12) g  and SGR (0.99±0.00)g/day. No significant difference (p>0.05) was observed in feed conversionratio across all treatments. There was no significant difference (p>0.05) observedin the survival rate between control (93.80±4.98)% and 80 PGLM (96.77±4.09)%.No significance difference (p>0.05) was observed in protein efficiency ratiobetween control (1.01±0.36) and 60 PGLM (0.95±0.36). There was no significantdifference (p>0.05) observed in nitrogen metabolism across all treatmentgroups. Hence, the inclusion level of 40 cells/1000 mL of L. plantarumfortified diet in cultured juvenile C. gariepinus was observed to have a bettergrowth enhancing performance and nutrient utilization than P. guajava leaf mealat 40g/1000g.
