The study of the zootechnical performance of Tilapia cabrae and Oreochromis schwebischi was carried out at the Mbolet fish farm in Lambaréné, Gabon. It was carried out with the aim of evaluating the growth and reproduction performance of these two species. For this purpose, 226 subjects, including 113 of T. cabrae with an average weight of 30.55 ± 9.5 g, and 113 O. schwebischi with an average weight of 20.64 ± 10.5 g, were distributed in four 6 m2 tanks with two replicates per species for the growth phase, which lasted 60 days. For the reproduction phase, 42 mature fish were selected, including 6 males and 36 females of each species. These were placed in six 2 m2 ponds with three replicates per species. The reproduction was monitored for 78 days. The survival rate, the number of reproductions per species and the absolute, relative and system productivity were determined.
