Abstract: Fish conservation in South America is a pressing issue. The biodiversity of fishes, just as with all other groups of plants and animals, is far from fully known. Continuing habitat loss may result in biodiversity losses before full species diversity is known. In this review, the main river basins of South America (Magdalena, Orinoco, Amazon and Paraná-La Plata system), together with key aquatic habitats (mangrove-fringed estuaries of the tropical humid, tropical semi-arid and subtropical regions) are analysed … Show more

“…Similarly, G. luteus was classified here as a marine straggler, while Barletta and Blaber (2007) considered it to be an estuarine species. These discrepancies highlight the need for more comprehensive information on the ecology and biology of the species inhabiting SW Atlantic estuaries (BARLETTA et al, 2010) to resolve such ambiguities.…”

“…However, river basins in Brazil are becoming increasingly transformed by human activities, particularly in the southeastern and southern regions, where land use change, pollution and damming for hydroelectricity are the main factors affecting fish conservation (Agostinho et al, 2008;Barletta et al, 2010). This continuous process of environmental change threatens the existence of fish species and their habitats, therefore conservation planning and prioritization require information on species composition and distribution in relatively large areas.…”

“…Small populations tend to reduce genetic diversity due to high rates of inbreeding, inducing a high rate of homozygosity (Woodruff, 2001;Frankham et al, 2008). In this context, the loss of habitat has direct consequences in reducing population size, and this is more evident, especially for species of fish from inland waters (Barletta et al, 2010), since they tend to be isolated in drains, resulting in distinct populations (Allan & Flecker, 1993).…”
