BEIJING — No survivors were found in a weeklong search for 39 crew members aboard a Chinese ocean fishing vessel that capsized in the central Indian Ocean, and seven bodies have been retrieved, China's Ministry of Transport said Tuesday.

A large-scale search operation has covered the possible area of drifting of the victims. At 3 am Tuesday, one week after the accident, the large-scale search operation began to downsize into a small-scale search operation for 48 hours.

On Sunday, three bodies were retrieved by Chinese fishing vessels, and another body was recovered from a cabin by divers from a Sri Lankan warship. Another three people were confirmed dead previously.
