Divers recovered 32 more bodies after seas calmed enough to resume search operations after a two-day suspension, increasing the death toll to at least 143.
More than 200 others are presumed to be missing, trapped in the wreckage about 165 feet below the surface.
Police Major Leonardo Ricci said the operation would continue “as long as the sea is calm and there is light.”
Congolese-born integration minister Cecile Kyenge watched with the island’s mayor as the bodies were lifted from boats on to trucks to be brought to a makeshift morgue at the airport.
“We cannot deal with this tragedy alone, but together with Europe. We must give answers to those who flee, need protection, and come here for help,” Kyenge told a news conference.
Earlier, Kyenge visited the survivors at a refugee center in Lampedusa. Most of the 155 survivors remain at an overcrowded center on the island, many sleeping in the open. Two have been transferred to hospitals in Sicily.
The migrants, mostly from Eritrea, were aboard the 65-foot fishing boat that sank early Thursday after passengers panicked by flames set to draw the attention bolted to one side of the boat, capsizing it.
Hundreds were flung into the sea, many who could not swim, while many were trapped in the hull.
Survivors told rescuers they were in the sea for three hours; many clung to empty water bottles to stay afloat and some were too weak to grab lifesavers thrown to them.
Lampedusa, Italy’s southernmost point and just 70 miles from Tunisia, is a frequent destination for migrants trying to reach a safe haven from misery and strife in Africa and the Middle East.
Tens of thousands arrive there each year seeking refugee status in Europe.
Survivors of Thursday’s tragedy have told authorities that a boat with lights had circled them but did not communicate or offer assistance.
A Dutch lawmaker has called for an investigation into reports that a boat did not help the stranded migrants.
There is no evidence that people on that boat knew that the fishing vessel was in distress.
Some of the survivors bade farewell Saturday to the 111 deceased fellow travelers who were recovered from the sea on Thursday. Their coffins stood in three long lines in the makeshift morgue at the island’s airport, each with a single rose except for four caskets for children topped with a teddy bear.
