The growth rates of Leporinus friderici (Bloch, 1974) in four populations from four rivers of French Guiana are compared. According to a statistical analysis of growth curves using the method of maximum likelihood with the Gauss-Markardt algorithm, a marked difference is observed in the growth of the different samples which is attributed to the year of capture rather than to the eographical origin of fishes. It is demonstrated that the main factor affecting growth performances is the length of the rainy season, with corresponds for this species to the feeding period. (Résumé d'auteur)
