  abstract = {{C}alcified structures such as otoliths and scales grow continuously throughout the lifetime of fishes. {T}he geochemical variations present in these biogenic structures are particularly relevant for studying fish migration and origin. {I}n order to investigate the potential of the {S}r-87/{S}r-86 ratio as a precise biogeochemical tag in {A}mazonian fishes, we compared this ratio between the water and fish otoliths and scales of two commercial fish species, {H}oplias malabaricus and {S}chizodon fasciatus, from three major drainage basins of the {A}mazon: the {M}adeira, {S}olimoes, and {T}apajos rivers, displaying contrasted {S}r-87/{S}r-86 ratios. {A} comparison of the {S}r-87/{S}r-86 ratios between the otoliths and scales of the same individuals revealed similar values and were very close to the {S}r isotopic composition of the local river where they were captured. {T}his indicates, first, the absence of {S}r isotopic fractionation during biological uptake and incorporation into calcified structures and, second, that scales may represent an interesting nonlethal alternative for {S}r-87/{S}r-86 ratio measurements in comparison to otoliths. {C}onsidering the wide range of {S}r-87/{S}r-86 variations that exist across {A}mazonian rivers, we used variations of {S}r-87/{S}r-86 to discriminate fish origin at the basin level, as well as at the sub-basin level between the river and savannah lakes of the {B}eni {R}iver ({M}adeira basin).},
