Public radio quoted the transport minister as updating the number of dead from 170 earlier in the day.
Joseph
Mkundi, a lawmaker for the Ukerewe district, told AFP there were 41
known survivors among the passengers of the MV Nyerere - a ferry built
to carry 100 people, according to state media.
It capsized on Thursday close to the pier on Ukara Island.
Although
hopes were fading of finding any more survivors by day three of the
search effort, workers rescued an engineer who had managed to locate a
pocket of air in the vessel.
According to Mkundi, the engineer had shut himself into a "special room".
Tanzanian President John Magufuli on Friday ordered the arrest of ferry management.
Witnesses
told AFP the ferry sank when passengers rushed to one side to disembark
as it approached the dock. Others blamed the captain, saying he had
made a brusque manoeuvre.
In a speech broadcast on TBC 1 public television, Magufuli said "it appears clear that the ferry was overloaded."
He added: "negligence has cost us so many lives... children, mothers, students, old people.
"I ordered the arrest of all those involved in the management of the ferry. The arrests have already begun," he added.
