Abstract: The study was carried out to evaluate the effect of Garcinia kola (biter kola) seed flour incorporated at 0, 1, 3, and 6% on reproductive traits (fecundity, egg diameter and gonado-somatic index (GSI)) and growth performance of Nile tilapia (Oreochromis niloticus L.). Eighty-four females and twenty-four males were grouped into the 4 dietary treatments (0, 30, 60 and 120gkg-1diet) labeled T0, T1, T3 and T6 and stocked at a sex ratio 7females:2males/treatment. Fish were fed 3% of their ichyno-mass for 44days corresponding to 4 spawns (11days/ spawn). Results showed that increased incorporation level of G. kola decreased fecundity (p< 0.05) irrespective of spawn and reduced by 35.3%, 83.28% and 83.45% respectively at 1, 3 and 6% when compared to the T0 at the last spawn. GSI increased with incorporation level (0.1%, 0.05%, 0.11% and 0.36 respectively at 0, 1, 3 and 6%) while egg diameter decreased (1.77mm, 1.90mm, 1.76mm and 1.71mm respectively at 0, 1, 3 and 6%) with incorporation level. Weight gain, specific growth rate and feed conversion ratio showed significant differences (p<0.05) among the dietary treatments with T6-fed fish exhibiting the best growth response (20.71g and 0.66%days-1) and feed utilization (1.52). This study proved that G. kola which is accessible year round in the tropics could be used by fish farmers to significantly control prolific breeding of Nile tilapia.
