Dos rios e dos peixes durante o calcolítico no Alto Douro Português

Abstract

This text aims to contribute to the understanding of the Chalcolithic walled enclosure of
Castanheiro do Vento (Horta do Douro, Vila Nova de Foz Côa) as a place forged in a profuse
network of practices, from which territories and landscapes were activated. To this end,
it analyses its relationship with the surrounding watercourses, as well as the remains of
ichthyofauna recovered during excavation. By demonstrating the importance of the Douro,
Torto and Teja rivers valleys in the network of places where the enclosure is located, we
discuss how the occurrence of barbel and shad/save allows us to deepen our knowledge of
this network. The migratory cycles of these fi sh and their reproductive behaviour, given its
seasonal character, are indicators of a cyclical temporality that would have structured the
dynamics of territories and landscapes.
