  abstract = {{S}molts of {A}tlantic salmon {S}almo salar of the {L}oire-{A}llier system have to perform an exceptional distance of 900 km to reach the ocean from the upstream spawning grounds, while being subjected to connectivity disruption induced by the presence of dams as well as fluctuating climatic conditions. {I}n order to successfully perform their marine entry, smolts should reach the estuary within a limited suitable period. {T}his study concerns smolt emigration dates from upper {A}llier, and arrival dates in the {E}stuary, as well as estimation by radio tracking of downstream migration speed. {C}omparison of these data revealed that a significant fraction of smolts from upper {A}llier leave breeding areas too late for successful marine entry. {T}his delay may be partly induced by dam retention. {W}e emphasize the importance of the clearing of the {P}ontes dam planed in 2015 and recommend to pursue and extend the current survey with additional monitoring stations along the migration axis, in order to study the fate of late migrants. {T}hese studies have major implications for the restoration of the threatened population of the {L}oire salmon.},
