The Socotra Archipelago is recognized globally as a UNESCO World Heritage Site. The unique ichthyofauna of Socotra accumulates fish species from different ecoregions, including commercial species which represent an important part of the local fishery. Positive identification of fish species and knowledge of their distributions are important for management strategies in fisheries and biodiversity conservation. Commercial fish species were collected at sea, taken from fish markets or landing sites, or observed underwater during two field trips in 2018 and 2019. Twenty-three new records of commercial fish species from twelve families are reported from the Socotra Archipelago based on collections and/or photographs: Plicomugil labiosus (Valenciennes, 1836); Epinephelus magniscuttis Postel, Fourmanoir et Guézé, 1963; Epinephelus marginatus (Lowe, 1834); Epinephelus morrhua (Valenciennes, 1833); Epinephelus rivulatus (Valenciennes, 1830); Alectis indica (Rüppell, 1830); Carangoides fulvoguttatus (Forsskål, 1775); Parastromateus niger (Bloch, 1795); Selar crumenophthalmus (Bloch, 1793); Uraspis helvola (Forster, 1801); Gerres oblongus Cuvier, 1830; Etelis coruscans Valenciennes, 1862; Diplodus omanensis Bauchot et Bianchi, 1984; Polysteganus coeruleopunctatus (Klunzinger, 1870); Lethrinus crocineus Smith, 1959; Gymnocranius elongatus Senta, 1973; Gymnocranius sp.; Wattsia mossambica (Smith, 1957); Argyrosomus japonicus (Temminck et Schlegel, 1843); Umbrina robinsoni Gilchrist et Thompson, 1908; Polydactylus plebeius (Broussonet, 1782); Histiopterus typus Temminck et Schlegel, 1844; and Siganus sutor (Valenciennes, 1835). The presence of the following three species are confirmed for Socotra Archipelago: Epinephelus malabaricus (Bloch et Schneider, 1801); Pristipomoides filamentosus (Valenciennes, 1830); and Sphyraena obtusata Cuvier, 1829. The following species represent the first verified records for the Arabian region: Epinephelus magniscuttis, Etelis coruscans, Lethrinus crocineus, Wattsia mossambica, and Gymnocranius sp. Species of two families, Sciaenidae and Polynemidae are reported for Socotra for the first time. Information on each species’ identification and its distribution are provided. Twenty-three commercial species new for the Socotra Archipelago were reported in this study, as a result, a total of about 255 species of fish are considered as exploited in the local small-scale fishery.
