%X An improved version of the quatrefoil light trap was tested in a tributary of the Sinnamary river, French Guiana, South America, at the beginning of the rainy season. The entire trap was simplified to lower the cost and increase the reliability of the entire system in harsh field work conditions. The major improvement was an inexpensive electronic light-switch that automatically lighted the lamp at dusk and turned it off at down allowing deployment of numerous traps over large distances. Most of the 648 individuals caught in the 76 samples were Characiformes larvae, juveniles, and small adults. Some Clupeiformes, Siluriformes, Cyprinodontiformes, Syngnathiformes and Perciformes were also caught but no Gymnotiformes were represented in the samples. Light traps appear useful to sample in their microhabitat neotropical young and small fishes of several taxonomic group. (Résumé d'auteur)
