Abstract
The prediction of the composition and structure of fish communities in reservoirs is essential in the management of the fisheries, all activity fundatmental in emerging countries where human riverine populations depend oil freshwater fish for their animal protein supply. The transformation of the river in a reservoir constitutes an environmental filter for the riverine fish species which, before anything else. must find food resources in the reservoir for their individual maintenance. After the closure of Petit-Saut Darn in 1994. fish were sampled by gillnets in the Sinnamary River in the period 1994-2000 and in the Petit-Saut Reservoir between 1998 and 2000. Th...
