Improvement of the agricultural production as well vegetable as animal remains the single solution to fight against malnutrition. This study was initiated in the objective to evaluate the performances of growth between Clarias gariepinus and Clarias ngamensis and their hybrids. The test was carried out during seven days to the zoological garden of Lubumbashi. The eggs of the females of each species were mixed then separate in 2 batches of which one is fertilized by the two males of the same species and the other by the two males of the other species. After fecundation, the eggs were incubated in 9 plastic basins in completely randomized device: 3 for C. gariepinus, 3 for C. ngamensis and 3 for the hybrids with 3 repetitions. At the resorption (three days post blossoming), the larvae were divided into 9 batches of the 120 larvae each one. The results obtained show that C. ngamensis presents a weaker performance on all the parameters evaluated except for the relationship between the weight of the laying and the live weight of parent. While C.. gariepinus and the hybrids presented performances very high this last specie would be advisable to the farmers of Lubumbashi to improve their production.

Abstract: (french)
L’amélioration de la production agricole tant végétale qu’animale reste l’unique solution pour lutter contre la malnutrition. Cette étude a été initiée dans l’objectif d’évaluer les performances de croissance des Clarias gariepinus et Clarias ngamensis et celles de leurs hybrides. L’essai a été conduit durant sept jours au jardin zoologique de Lubumbashi. Les œufs des femelles de chacune de ces deux espèces ont été mélangés puis séparés en 2 lots dont l’un est fécondé par les deux mâles de même espèce et l’autre par les deux mâles de l’autre espèce. Après fécondation, les œufs ont été incubés dans 9 bassines en plastique suivant un dispositif complètement randomisé : 3 pour les C. gariepinus, 3 pour les C. ngamensis et 3 pour les hybrides avec 3 répétitions. A la résorption (trois jours post éclosion), les larves ont été réparties en 9 lots des 120 larves chacun. Les résultats obtenus montrent que le C. ngamensis présente une plus faible performance sur tous les paramètres évalués à l’exception du rapport entre le poids de la ponte et le poids vifs de géniteur. Tandis que le C. gariepinus et les hybrides ont présenté des performances très élevées .Cette dernière espèce serait recommandable aux fermiers de Lubumbashi en vue de l’amélioration de leur production.
