The capture of the cornich blackfish, Schedophilus medusophagus , larvae from the Adriatic Sea represents an easterly extension in range of this species, and the first larval record in Adriatic waters. Schedophilus medusophagus Cocco, 1839, is a mesopelagic species from temperate waters of the north-eastern and north-western Atlantic and the western Mediterranean (Bini, 1968; Tortonese, 1975; Haedrich, 1986). The first record of this fish from the Adriatic Sea was reported in 1880 according to Ninni (1912). The second record was during the invasion of medusae Pelagia noctiluca (Malej, 1982; Rottini-Sandrini & Stravisi, 1982; Vučetić, 1982,1983) in Pelješac channel near the town of Korčula-island Koršula (central Adriatic) in 1982 (Onofri, 1986). Ten juvenile specimens, from 10·0 to 20·0cm total length (TL), were collected with medusae at 2m depth. This record Onofri (1986) connected with the ingression of inter-median waters (50–100 m) in the central Adriatic influenced the increase of salinity and temperature in 1982. Jardas (1996) noted that S. medusophagus is a very rare species in the Adriatic Sea.
