Twenty people died, including 15 young children, when a boat on the Niger river broke up near the central Malian city of Mopti, officials say, adding that another 23 people were missing.
"We don't know yet why the boat broke up," Commander Dramane Diallo, from the rescue services, told AFP on Saturday after the overnight sinking.
"Investigations are under way. The boat broke at the stern" in a branch of the river near the village of Koubi, some 70km north of the regional capital Mopti, and 210 passengers survived the accident, he said.
Senior civil protection official, commander Naman Keita, confirmed the latest toll, adding that 15 children aged under five were among the recovered bodies.
The search for survivors and more victims was suspended overnight and would resume on Sunday morning, he added.
Diallo said the large dugout was also loaded with goods. No further details were immediately available.
The governor of Mopti said the Malian rescue services were assisted by residents of Koubi and passing boats.
"This is what allowed for 20 bodies to be recovered. The search and rescue operation is ongoing," Ibrahima Hama Traore said on public television.
He said that accidents were not uncommon on the river but that the human loss from Friday night's disaster was "extremely unusual".
Traore said consultations would be undertaken with river transport companies to regulate traffic and prevent overloading.
Those rudimentary canoes are the main means of transportation for residents of Mali's central and northern regions travelling to the towns dotting the Niger, the main river in West Africa.
Often powered by a van motor, they can sometimes carry tonnes of merchandise as well as over 100 passengers.
