Résumé :	In order to determine the inshore migration mechanisms of the tropical eel Anguilla marmorata (Quoy et Gaimard, 1824) entering the Poso estuary (Sulawesi, Indonesia), glass eels were collected throughout 1999. We subjected these samples to morphological examination and aged a subsample. Environmental factors were investigated. Glass eels were active at night, with high activity between 02.00 and 04.00 o'clock. Migration was initiated by increase in water flow. The peak of migration occurred in January-March. Pigmentation stages, length, weight and factor condition were analysed and showed variations. A subsample of glass eels was aged by examinations of sagittal otoliths. Duration of marine larval stage was estimated to be 97-102 days and discussed.
