In the lower Tocantins, Amazonian Brazil, 2 species of migratory fish dominate the captures: Hypophthalmus marginatus and Prochilodus nigricans. These two species were studied before the damming of this river by the Tucurui hydroelectric dam. A simple pattern of migration can be recognized: an upstream movement of immatures and adults in the upper part of the distribution area, and then the reverse or downstream movement of larvae and adults in a dispersion phase. -from English summary |
