Seasonal influence on the bathymetric distribution of an endangered fish within a marine protected area

Abstract The spatio-temporal variability of fish distribution is important to better manage and protect the populations of endangered species. In this sense, the vertical movements of a vulnerable and protected species, Sciaena umbra, were assessed in a marine protected area (the Réserve Naturelle M...
