Costa Crociere confirmed Wednesday it fired Costa Concordia Capt. Francesco Schettino, the Italian news agency ANSA reported.
Schettino has apologized for being distracted the night his ship ran aground on the island of Giglio off the Tuscan coast.
He said his dismissal was unfair because he was not in command of the ship when it hit a rock.
Schettino is under investigation for manslaughter, abandoning his post before all passengers and crew were evacuated and failing to communicate properly with maritime authorities.
The accident in January was Italy's worst maritime disaster since World War II.
