Aim To evaluate alpha and beta diversity of coastal marine fishes across different spatial scales—habitat, regional, and biogeographical—along a 14° latitudinal gradient (41° S–55° S). Location Southern Southwest Atlantic Ocean (SWA). Taxon Coastal marine fishes. Methods We sampled four benthic habitats—rocky reefs, soft bottoms, transition habitats, and kelp forests—across seven shallow coastal sites (≤ 30 m depth) spanning d...

Coastal rocky fish species support important fishing activities, but basic information is lacking for many before catches decline. Monitoring and management of coastal rocky fish species is urgently needed in Chile, but knowledge of these species is fragmentary at best. Performance of Baited Remote Underwater Video Stations (BRUVS) for assessing rocky fish assemblages was evaluated in south‐central Chile. Seven medium‐ to larg...
