Description
Summary:National audience Literature review dedicated to eel civelle (Anguilla anguilla L.) migration in estuaries, and comparison to original data (abundance, structure in weight and in pigmentary stages) taken in the Gironde estuary in order to understand the process of this migration. The analysis of the specimens characteristics shows a high interannual regularity. The influence of the main environment factors on these specimens is quite clear. Analyse de la littérature consacrée à la migration estuarienne de la civelle d'anguille (Anguilla anguilla L.) et confrontation à des chroniques de données originales (abondance, structure en poids et en stades pigmentaires) issues de l'estuaire de la Gironde afin de comprendre la façon dont se déroule cette migration. L'analyse des caractéristiques des individus montre une haute régularité interannuelle. L'action des principaux facteurs environnementaux sur les individus en migration apparaît assez nette.
