The change of density and/or activity of fish in the channel was registered by the sonar whose echo-marks exhibited two peaks at dawn and dusk. During the night[,] the density of echo-marks was stable and low in absence of the fyke-net, but it increased when the presence of the fyke-net limited the migratory flow and fish accumulated before the [fishing] gear. 2, record 2, English, - echotrace

La variation de densité et/ou d’activité des poissons enregistrée par le sonar(écho-traces), montre un profil nycthéméral comprenant un pic à l'aube et un autre au crépuscule. La densité nocturne d’écho-traces, relativement stable entre ces deux pics, tend à augmenter en fin de nuit lorsque le verveux barre le chenal, ralentissant ainsi le flux migratoire qui s’accumule devant l'engin [de pêche]. 2, record 2, French, - %C3%A9chotrace
