Food web diagram based on the catches of fish and benthic macroinvertebrates, as well as on the diet analysis of selected fish, showing the main trophic interactions in the two reservoirs analyzed. FI = Feeding Index (the main trophic interactions were derived from FI results). Funil reservoir (A): C. piquiti (1), H. intermedius (2), H. malabaricus (3), G. knerii (4), O. pintoi (5), A. lacustris (6), M. amazonicum (7), A. altiparanae (8), P. fasciatus (9), G. brasiliensis (10), L. friderici (11), S. nasutus (12), P. maculatus (13), S. insculpta (14), terrestrial insects (15), Corixidae (16), pupae (17), Chironomidae larvae (18), Chaoboridae larvae (19), Trichoptera larvae (20), C. fluminea (21), Cladocera, Ostracoda, and Copepoda (22), filamentous algae (23), periphyton (24), and plants (25). Volta Grande reservoir (B): P. squamosissimus (1), S. maculatus (2), C. kelberi (3), C. piquiti (4), H. intermedius (5), M. amazonicum (6), A. altiparanae (7), P. fasciatus (8), L. friderici (9), S. nasutus (10), C. britskii (11) A. facetus (12), A. crassipinnis (13), S. pappaterra (14), fish scales, fins, and muscle (15), adult insects (16), Chironomidae larvae (17), A. tenuilabris (18), M. tuberculata (19), C. fluminea (20), Physa sp. (21), L. fortunei (22), Cladocera, Ostracoda, and Copepoda (23), submerged macrophyte (24), and plants (25). The fish species common to the two reservoirs are represented in gray, and the non-native taxa are indicated with asterisks.
