Abstract: Rio Paraopeba, a tributary of rio São Francisco, has a six-meter high dam, built in 1978 to divert water to the Igarapé Thermal Power Plant. In 1994, a fish ladder was built at this dam. The results of a marking and recapture program carried out along rio Paraopeba between 1997 and 2001 are described, using information from fish community studies conducted at ten sampling stations between 1994 and 1997. These investigations showed the presence of at least 91 species in the river. During four rainy seasons betw… Show more

“…These results suggest that the larvae are adapted to more intense luminosity, normally found in the water column, where they swim actively starting on the fourth day of life (Godinho et al, 2003) and retain this behavior during the adult phase when they migrate for reproduction (Silva et al, 2006;Alves, 2007).…”

“…Pacamã is a piscivorous species (Alvim & Peret, 2004) that is distributed on the bottom, with the adults building nests in sandy ponds where they spawn (Travassos, 1959). The curimatá-pioa are detritivorous and active swimmers, migrating upriver to reproduce (Silva et al, 2006;Alves, 2007), and their larvae swim in all directions and levels of the water column, from the fourth post-hatching day (Godinho et al, 2003).…”

“…However, in the Paraopeba River, these species are threatened by human activities, such as mining, discharge of industrial effluxents and domestic sewage, overfishing, destruction of gallery forests, and the draining of wetlands in support of agricultural development [10]. The Paraopeba River has two older dams in its upper section [11] (Igarapé Thermoelectric Dam and Salto do Paraopeba) and a third one built in 2010 in its lower section (Retiro Baixo Hydroelectric Dam; Figure 1). …”

“…Few studies concerning movement patterns and home range of tropical fishes are known. Among all known records we highlight those related to large rivers from Amazonian, Paraná, Uruguay and other large basins (Goulding 1980, Agostinho et al 2003, Alves 2007, Antonio et al 2007, Fernadez et al 2007, Tejerina-Garro & Merona 2010. Although there are no movement studies for stream-dwelling fish communities from Mata Atlântica, Mazzoni et al (2004) registered some evidences of upstream migration related to reproduction among a Characiform species from a coastal stream in Southeast Brazil.…”
