Feeding aspects of Leporinus amblyrhynchus (Characiformes: Anostomidae) in the first stages of formation of a Neotropical reservoir, Brazil

Diet and feeding activity of Leporinus amblyrhynchus before, during and after the damming of the rio Corumbá (Goiás State March 1996 to February 1998) were investigated. The diet, evaluated using the Feeding Index (IAi), showed that this species presents an invertivore feeding habit, preying on basi...

description Diet and feeding activity of Leporinus amblyrhynchus before, during and after the damming of the rio Corumbá (Goiás State March 1996 to February 1998) were investigated. The diet, evaluated using the Feeding Index (IAi), showed that this species presents an invertivore feeding habit, preying on basically Chironomidae larvae. The feeding activity, estimated using the quantity of food in the stomach during a 24-hour cycle, showed that the feeding occurs mainly in the daytime. Considering the feeding aspects of this species during the formation of the reservatório of Corumbá there were small variations in the parameters (diet and feeding activity) dealt in this study.
