Abstract

This paper presents data collected in the Upper Maroni, French Guiana during 5 field missions from 2000 to 2002. A total of 123 known species, classified into 34 families, was captured. Fish communities sampled vary during the year depending on the season. On a daily cycle, fish composition also clearly varies, with a predominance of Siluriformes and Gymnotiformes during the night. Our results give a historical overview of the fish fauna in Upper Maroni 20 years ago. At this time, threatened fishes were already recorded due to overfishing and in certain areas, habitat alteration (turbidity and pollution).
