Body condition and energy density of juvenile streaked prochilod Prochilodus lineatus (Valenciennes, 1837) in a Neotropical floodplain Neotropical Ichthyology
Corbetta,Daiany de Fátima; Veronezzi,Ana Lúcia; Benedito,Evanilde.
ABSTRACT Variations in energetic density (E D ) and the relative condition factor (K n ) of juveniles of Prochilodus lineatus were investigated to identify whether these two variables respond similarly to environmental factors. We hypothesized that fluviometric levels in different sub-basins of the Upper Paraná River floodplain positively influence the E D and K n of juvenile fish. Temporally, the values of E D and K n were linked more directly to the dynamics of the flood pulses on the plain. Spatially, the lowest values of E D and K n were observed in the environment that was directly affected by the operation of dams, the sub-basin Paraná. Although the energy density and condition factor did not show similar results for juveniles in some of the...
