  abstract = {{I}n the {A}mazon, migratory catfishes of the genus {B}rachyplatystoma are apex predators that are important for fisheries and conservation. {T}he life cycle of {B}rachyplatystoma platynemum {B}oulenger, 1898 is poorly known, although it has been hypothesized to be very similar to that of {B}rachyplatystoma rousseauxii {C}astelnau, 1855, which uses the entire length of the {A}mazon basin to complete its life cycle (from the {A}ndes to the estuary). {T}his study provides the first data on the migratory patterns of {B}.platynemum at the individual level using otolith microchemistry. {I}n total, 94 individuals were sampled close to major breeding areas in the {A}mazon basin (78 fish from the middle and upper {M}adeira {R}iver and 14 fish from the upper {A}mazon), and their lifetime movements were assessed by measuring variations in {S}r-87/{S}r-86 along transverse sections of their otoliths (ear stones), using laser ablation multi-collector mass spectrometry ({LA}-{MC}-{ICP}-{MS}). {T}he migrations of {B}.platynemum are not as extensive as those of {B}.rousseauxii, and do not involve natal homing. {F}urthermore, the estuary is not a nursery area, at least for fish hatched in the {M}adeira. {N}evertheless, {B}.platynemum migrates several thousand kilometres within the {A}mazon basin, with transboundary displacements between at least {B}olivia, {B}razil, and {P}eru. {C}urrent and planned hydroelectric development in the {A}mazon basin will severely disrupt both migration and access to breeding grounds, ultimately affecting the recruitment and population dynamics of these apex predators. {T}he conservation of {B}.platynemum is crucial for the stability of the {A}mazonian aquatic food webs. {T}his requires building effective fish passage on the two existing {M}adeira dams and considering alternative options to the large-scale hydropower development in the {A}mazon basin.},
