Carnival Corp & Plc , the world's largest cruise operator, reported a drop in quarterly profit on Friday as lower cruise ticket prices hurt revenue.

Miami-based Carnival reported net income of $193 million, or 24 cents a diluted share, for the fourth quarter ended November 30, down from $371 million, or 47 cents a share, a year earlier.

The average analyst estimate for Carnival's fourth quarter results was 20 cents per share, according to Thomson Reuters I/B/E/S.

Revenue fell about 3 percent to $3.2 billion from $3.3 billion a year earlier.
