Some 200 people survived but there were about 450 aboard and rescuers have no hope of more survivors.
Bodies from the Dieu Merci are being buried three or four to a grave along the wooded shore of Lake Mayi Ndombe.
Authorities in the nearby town of Inongo are questioning the overcrowded ferry's owner and other officials.
Boat disasters are common on DR Congo's vast network of river and lakes, the BBC's Arnaud Zajtman reports, but Inongo has not seen such a disaster in years.

'Everyone fell in the water'
The ferry, which appears to have actually been two vessels lashed together, ran into trouble when one of its boats' engines seized up.
Survivors say it went under in a matter of minutes after a storm blew up, sending waves nearing 2 metres (8 feet) in height to crash against the hulls, slamming the vessels together.
"When the boat split, everyone fell in the water, searching for something to hold onto," survivor Bienvenue Mwanku told AP news agency.
Another survivor, Deogratias Lulengwa, managed to stay afloat by grabbing a jerry can and waiting until he was picked up by fishermen. But his wife was among the drowned.
With only 30 passengers listed in the ferry's manifest, officials believe the exact number of victims may never be known. Aid workers believe the ferry had been designed to carry no more than 100 passengers.
