abstract: In Zambia fish farms, Oreochromis andersonii is an important common indigenous fish species. Naturally, safe phytochemicals can effectively improve hsif reproduction performance and their production potential. Therefore, this study was conducted to determine the effect of Kigelia africana on the gonadal development and the performance of Oreochromis andersonii. A total of 96 male fingerlings were randomly assigned to four dietary treatments (D1-D4), and each treatment group had three replicates. The D1, D2, D3, and D4 groups were formulated to receive 0, 50, 100, and 150 g of powdered Kigelia africana/kg, respectively. The fish were fed the diets for 9 weeks, followed by the study parameter measurements at the end of the experiment. The highest mean body weight and gonadal weight were (29.8 ± 0.63 and 0.09 ± 0.010 g, respectively) for fish in the D2 group. There was no significant difference between the mean body weight of fish in different groups, but their mean gonadal weights differed significantly. The gonadal somatic index of fish differed significantly among treatment groups, with those in D2 having the highest mean value (0.36 ± 0.060). The highest mean standard length (103.3 ± 0.63 mm) and total length (126.0 ± 0.11 mm) of fish were observed for D1 and D2 groups, respectively. Additionally, the mean values for those parameters decreased with increasing Kigelia africana in the diet. The physicochemical parameters of water, including temperature and dissolved oxygen, ranged 16.8-23.1°C and 0.6-2.2 mg/L, respectively; these were generally at low levels considering the optimum requirements for this fish species. In conclusion, Kigelia africana improved gonadal growth and development but did not promote overall fish growth. The best gonadal growth/development results of Kigelia africana powder were observed at a level of 50 g/kg, which can be used as a performance booster in the aquaculture production of Oreochromis andersonii © 2023, World's Veterinary Journal.All Rights Reserved.
