Habitat use and food sources of European flounder larvae (, L. 1758) across the Minho River estuary salinity gradient (NW Iberian Peninsula).

The European flounder ( Linnaeus, 1758) exhibits plasticity for several life traits throughout its distribution range, including ontogenetic habitat shifts during early life, as well as the timing and duration of spawning. Estuaries are preferred as nursery habitat; however, the importance of specific salinity zones for larval development is not well-understood. Therefore, we aimed to identify the significance of distinct estuarine salinity habitats (i.
