Social networks allow early detection of non indigenous species: first record of the red drum Sciaenops ocellatus (Actinopterygii: Perciformes: Sciaenidae) in Italian waters

Description
Summary:The red drum Sciaenops ocellatus is a large demersal fish that represents one of the top predators in estuarine environments of its native range. This species is commonly reared in aquaculture facilities, and it has already been reported as non indigenous from several countries. Here we report its first sighting in Italian waters, as well as the second documented occurrence for the Mediterranean Sea. The individual was landed in southern Sicily by artisanal fishery and this unusual observation was immediately shared on Facebook. The importance of considering social networks as tools for NIS detection is briefly discussed in light of the recognized difficulties to properly track biological introductions in the marine environment. Crvena hama, Sciaenops ocellatus, je velika demersalna riba, koja je jedna od najvećih grabežljivaca u estuarijskim okruženjima njezinog prirodnog areala rasprostranjenja. Ova vrsta se obično uzgaja u akvakulturi, a već je zabilježena kao nezavičajna u nekoliko zemalja. U ovom radu utvrđeno je prvo viđenje ove vrste u talijanskim vodama, koje je ujedno druga dokumentirana pojava u Sredozemnom moru. Primjerak je ulovljen tijekom priobalnog ribolova u južnoj Siciliji. Ova neuobičajena pojava je odmah podijeljena na društvenoj mreži (Facebook). Važnost razmatranja društvenih mreža kao alata za otkrivanje nezavičajnih vrsta kratko je raspravljan u svjetlu prepoznatih poteškoća kako bi se pravilno pratili biološki unosi u morski okoliš.
