comparable to half of the total fish larvae and had density equivalent to total fish
eggs along the main channel (Lima et al. 2014).
The ingestion of plastic threads by subsistence and commercial demersal fishes
was observed in 20% of ariid catfishes (Cathorops spixii, C. agassizii, Sciades herzbergii) (Possatto et al. 2011) and 13% of Gerreids (Diapterus rhombeus, Eugerres
brasilianus, Eucinostomus melanopterus) (Ramos et al. 2012). In sciaenids, it was
registered a contamination of 8% of Stellifer (S. brasiliensis, S. stellifer) (Dantas
et al. 2012) and 100% in adult Cynoscion acoupa (Ferreira et al. 2016) (Table 20.1).

The importance of the São Francisco River is not only related to the amount of
water carried across a semi-arid region, but mainly to its historical and economic
contribution to the establishment of communities on a basin-wide scale and the
