Pour une meilleure survie, les larves de la perche fluviatile Perce fluviatilis L., qui sont en general de petite taille, ont ete nourries, des l\'eclosion, avec deux proies vivantes : le Rotifere d\'eau douce (Brachionus calyciflorus) et le nauplii d\'Artemia salina. Pour minimiser les mortalites dues aux manipulations des larves de la perche fluviatile, la mise en place a ete effectuee a partir d\'oeufs oeilles prets a eclore. Les larves, qui ont recu des Rotiferes dans leur aliment de demarrage, ont presente une population plus homogene par rapport a celles ayant recu exclusivement des nauplii d\'A. salina. Les meilleurs taux de survie et de conversion alimentaire ont egalement ete obtenus dans le premier groupe. Cette etude a egalement montre que toutes les larves de la perche fluviatile ne sont pas capables d\'ingerer les nauplii d\'Artemia a l\'eclosion In order to improve survival rate and growth in perch Perce fluviatilis larvae, which are very small in size at haching stage, larvae were submitted, two days after haching, to different live foods : fresh water Rotifera Brachionus calyciflorus and nauplii of Artemia salina. Thus, to avoid the important mortality, which occured because of larvae handling, eggs at eye stage were alocated into two groups. Feeding of larvae started two days after haching. At the end of the experiment, the group fed withe Rotifera at in their stater diet, exhibited the best homogeneity, survival and food convertion ratio. The study has clearly shown that at haching, allperch larvae were not able to ingest nauplii Artemia.
