Abstract

The Capivara Reservoir is located at the Medium Paranapanema river, between the states of Paraná and São Paulo and was formed in 1977. Samples made in 2001 and 2002 yielded 62 fish species, 31 of which occurred in the studied stretch. The nine most abundant species were chosen for the ecomorphological analysis. Eight ecomorphological attributes related to habitat use and foraging were employed in order to identify existing ecomorphological patterns among the species as well as relating them to the main food it…
