This contribution presents the first record of the noble crayfish Astacus astacus (Linnaeus, 1758) in Euboea (Evia) Island, Greece. The crayfish was found during a fish monitoring expedition in the upper Mesapios River, in a reach that maintains flow throughout the year, while most of the river length desiccates completely during the dry season. The finding of A. astacus in an intermittent river of Euboea Island expands the species geographical range and calls for immediate conservation actions to protect its habitat and preserve this vulnerable population.
Résumé
Cette contribution présente le premier signalement de l'écrevisse noble Astacus astacus (Linnaeus, 1758) dans l'île d'Eubée (Evia), en Grèce. L'écrevisse a été trouvée lors d'une expédition de surveillance des poissons dans le cours supérieur de la rivière Mesapios, dans un tronçon qui maintient le débit toute l'année, tandis que la majeure partie de la longueur de la rivière se dessèche complètement pendant la saison sèche. La découverte d?A. astacus dans une rivière intermittente de l'île d'Eubée étend l'aire de répartition géographique de l'espèce et appelle à des actions de conservation immédiates pour protéger son habitat et préserver cette population vulnérable.
