%X Post fishing mortality of the glass eel was monitored in 2007 in the Vilaine estuary. The mortality of the glass eels varied from 2 to 82% (mean 42%) in the two days following the fishing. The mortality of samples collected by hand nets or from the trapping ladder was null. Alterations of the skin mucus were analyzed by the use of Indigo carmine. The mortality was significantly correlated with body injuries, but not to other environmental factors. The presence of a large injury on the body systematically led to the death of the glass eels, and among these dead glass eels, only 3.5% had no external injury. These results are discussed, along with the results from other estuaries, with a view to transport glass eels across Europe, with the objective of restoring the eel stock. Les mortalit¨¦s de civelles ont ¨¦t¨¦ suivies en 2007 dans l¡¯estuaire de la Vilaine. Ces mortalit¨¦s ont vari¨¦ de 2 ¨¤ 82 % (moyenne 42 %) dans les deux jours suivant la p¨ºche. Les mortalit¨¦s d¡¯¨¦chantillons p¨ºch¨¦s ¨¤ l¡¯aide de tamis ¨¤ main ou captur¨¦s dans la passe ¨¤ anguilles ¨¦taient nulles. Les alt¨¦rations du mucus de la peau ont ¨¦t¨¦ analys¨¦es ¨¤ l¡¯aide de carmin indigo. Les mortalit¨¦s ¨¦taient significativement corr¨¦l¨¦es aux blessures sur le corps mais pas aux facteurs de l¡¯environnement. La pr¨¦sence d¡¯une importante blessure sur le corps m¨¨ne syst¨¦matiquement ¨¤ la mort des civelles, et au sein des civelles mortes, seules 3,5 % ne portent pas de blessure externe. Ces r¨¦sultats sont discut¨¦s, avec ceux obtenus dans d¡¯autres estuaires, par rapport ¨¤ l¡¯objectif de transporter des civelles en Europe en vue de restaurer le stock d¡¯anguilles.
