  abstract = {{H}igh-resolution multibeam sonar allows estimating movements of pelagic fish schools at short range. {T}aking advantage of this methodology, we calculated a {S}traightness {I}ndex ({SI}) to quantify the proportion of schools migrating actively from those residents in lagoon channels. {T}his information enhances our knowledge of both fish school displacements and migration processes, which are essential to improve our understanding of ecosystem functioning. {M}ost fish schools (65%) exhibited a {SI} value demonstrating oriented swimming behavior through the channels displayed by schools reaching the sea during fall migration. {T}his trend appears as an intrinsic property of school movements, allowing monitoring of the school migration process in a channel to provide information for manager vs. fishing regulation measures or lagoon planning. {T}he result strengthens the 'multi-transit' hypothesis, as 35% of schools show sinuous trajectories representative of schools staying in the channel or displaying high exploratory behaviors. {L}astly, the fish school {E}xploration {S}wimming {S}peed ({ESS}) was tested as a fishery-independent sampling method to evaluate the proportion of different fish species monitored using hydroacoustics. {T}his approach demonstrates the interest in using swimming behavioral characteristics of fish schools for ecological and management purposes.},
