Azores Ecosystem Overview

​​Impacts on threatened and declining fish species in the Azorean ecoregion

​Several fish species that have been adversely affected by fishing in the Atlantic are now on the OSPAR list of threatened and declining species (see full list in Table 1). These include the spurdog (Squallus acanthias), the common skate complex (Dipturus spp.), porbeagle (Lamna nasus), and some deep-water sharks. Although there are either zero TACs for these species, or they are listed as prohibited, several of them remain vulnerable to existing fisheries.
