Abstract: The feeding ecology of Leporinus taeniofasciatus in the upper rio Tocantins was characterized before (river phase) and after (reservoir phase) its impoundment by the Serra da Mesa Hydroelectric Dam. The importance of each food item was given by the Alimentary Index (IAi), which combines the frequency of occurrence and volumetric methods. A significant difference in the diet of L. taeniofasciatus between seasons in the river phase, detected by a multivariate analysis of variance, was not kept when the reservoir… Show more

“…The stomachs analysed had their food items identified and quantified (to the level of order) by the volumetric method according to Albrecht and Pellegrini-Caramaschi (2003). The volume measurement and the frequency of occurrence were analysed using the Alimentary Index (IAi) proposed by Kawakami and Vazzoler (1980).…”

“…In October 1996 the upper stretch of the Tocantins River was impounded by the Serra da Mesa Hydroelectric Dam, flooding an area of approximately 1,700 Km² after filling completion. With a volume of 54,4x10 9 m³ this is the largest reservoir in terms of storage capacity in Brazil (De Fillipo et al, 1999), located within the geographical coordinates 14°38'36"S 48°59'14"W and 14°03'57"S 48°29'37"W. A map of the study region can be found at Albrecht & Pellegrini-Caramaschi (2003). Before the impoundment, the affected portion of the river was a succession of waterfalls, riffles and pools within steep banks, flowing through a hilly terrain covered by Cerrado vegetation.…”

“…Food items were identified to the lowest taxonomic category and quantified through the volumetric and frequency of occurrence methods. Volumes of items consumed were quantified on a 1-mm-high transparent dish with a 1 x 1 mm grid beneath, as described in Albrecht & Pellegrini-Caramaschi (2003). For each stomach we also counted the number of scales and determined the percentage of scales related to other items by dividing the volume of scales by the sum of volumes of all food items.…”

“…Species of Leporinus are considered to be mainly bottomassociated feeders, due to the presence of sediment and benthic organisms such as insect larvae and filamentous algae in their stomach contents (Albrecht et al, 2003a(Albrecht et al, , 2003b). This assumption is also supported by the species' sub-terminal mouth (Albrecht et al, 2001), although mouth arrangement is not always a strong indicator of feeding habit for anostomids (Santos & Rosa, 1998).…”
