During seaward migration, allis shad and twaite shad juveniles move through the estuary. The question is: do juveniles stay in the estuary? The present study, that focuses on the Gironde-Garonne-Dordogne watershed, examines retrospectively the role of the estuary during seaward migration, by using otolith Sr/Ca ratio analysis. Analysis is carried out on the otoliths of spawners, individuals that successfully complete their life cycle (the winners). Otolith daily growth increments and our ability to identify the entrance into brackish (estuarine) water and seaward exit on the otolith are validated. The time spent in freshwater and brackish water, the size at which habitat shift occurs, otolith microstructure, and also the data collected from...
