Abstract: We led an experimental study tending to evaluate the impact of two species introduced, Gambusia affinis and Cyprinus carpio on the wetlands of Numidia. Our results clearly state that the predation of fish is an important factor influencing the composition and the structure of the watery biocenoses and that the introduction of exotic fish represents a real threat for Algerian wetlands.
