Knowledge regarding the marine phase of twaite shad (Alosa fallax (Lacépède, 1803)) and allis shad (Alosa alosa (Linnaeus, 1758)) remains limited. To understand the coastal and continental distribution and dynamic of migration of these species, in the present study we collected official data records of marine landings (kg), separated according to species, for all fish markets in Galicia (north-west of the Iberian Peninsula) and undertook freshwater field sampling campaigns. The findings indicate that both species of shad exhibit a coastal distribution near the rivers where they spawn, namely the Minho and Ulla rivers. Catches at sea declined from January, a phenomenon that can be understood as the onset of migration to the rivers. Bycatch reports are important because both A. fallax and A. alosa are listed in the Annex V of the European Union Habitats Directive, which lists animal species whose exploitation and taking in the wild may be subject to management measures. However, for a better management of these species it is necessary to understand the magnitude of displacements and connection of shad populations at sea.
