Le r???gime alimentaire des poissons est d'une importance capitale dans les processus de r???gulation des ???cosyst???mes aquatiques, car il ne d???note pas tant la disponibilit??? de la nourriture distribu???e dans l'habitat que les choix effectu???s par les individus. Cette ???tude a ???t??? r???alis???e dans deux cours d'eau situ???s dans le bassin hydrographique du Peixe - Boi / PA, ??? diff???rents stades d'anthropisation, dans le but de comparer le r???gime alimentaire de l'ichtyofaune, de classer les esp???ces analys???es selon leurs habitudes alimentaires en carnivores, herbivores et omnivores, d'identifier l'origine des ???l???ments dont ces animaux se nourrissent, qu'ils soient allochtones ou autochtones, et de caract???riser la fa???on dont ces observations peuvent ???tre faites par rapport aux esp???ces de poissons pr???sentes dans les cours d'eau. L'importance absolue des aliments peut ???tre d???duite en fonction du degr??? d'int???grit??? des masses d'eau. Le contenu stomacal de 58 individus a ???t??? analys???. Chaque ???l???ment a ???t??? pes??? et identifi??? jusqu'au plus petit taxon possible, ce qui a permis de calculer leur fr???quence d'occurrence (Fi), l'indice d'analyse volum???trique (Vi) et l'indice d'importance absolue (AIi).
