Zusammenfassung:On July 7th 2018 a specimen of Mediterranean dealfish (Trachipterus trachypterus Gmelin 1789) was caught in the shallow waters of Selinunte (in the South-Western coast of Sicily) by trammel net. It was a female in maturing phase and the gonadosomatic index resulted as 1.1%. The specimen measured 1638 mm in total length and weighed about 2480 g. The estimated age through growth increments in vertebra was of 41 years. The finding of the Mediterranean dealfish in the Strait of Sicily might be linked to its spawning period during which it approaches the shallow waters. The present specimen represents the first record in the Strait of Sicily. Dana 7. srpnja 2018. uzorak mediteranskog dealfish (Trachipterus Trachypterus Gmelin 1789) je uhvaćen u plitkim vodama primorskog mjesta Marinella di Selinunte (na jugozapadnoj obali Sicilije) s troslojnom mrežom. Bila je to ženka u fazi sazrijevanja, a gonadosomatski indeks rezultirao je 1,1%. Uzorak je izmjeren 1638 mm ukupne duljine i težio je oko 2480 g. Procijenjena dob kroz povećanje rasta kralježaka bila je 41 godinu. Otkrivanje mediteranskog delfish u Sicilijskoj tjesnac mogao bi biti povezan s njegovim razdobljem mrijesta tijekom kojeg se približava plitkim vodama. Sadašnji uzorak predstavlja prvi zapis u Siciliji.
