The aim of this study was to establish the growth rate and food conversion ratio of pikeperch (Sander lucioperca) when fed with carp (Cyprinus carpio). The experiment was carried out under controlled laboratory conditions. Ten pikeperch with body weight between 140 - 220 g were stocked individually in cages placed in tanks for a period of 30 days. Carp with body weight of 6.28+0.14 g were used as prey fish. For a period of 30 days at an average water temperature of 14.52±0.380C and dissolved oxygen of 8.11±0.13 mg.l-¹ pikeperch fed with carp realize an average increase of the body of 46.78±4.93 g. The mean achieved FCR is 4.83 as the lowest is 3.82, and the highest 7.07.
