(CNN) Rescue teams are expected to resume their search for hundreds of missing ferry passengers Friday, after a dangerously overcrowded boat capsized on Lake Victoria in Tanzania's north.

At least 44 people died when the passenger ferry sank between two islands in Lake Victoria on Thursday.

Images from the scene showed rescuers in boats alongside the overturned ferry, picking up survivors in orange life rings. The rescuers were also retrieving bodies from the water.

Only 37 people were rescued from the water before poor visibility halted operations.

Regional Commissioner John Mongella told local Tanzania television channel ITV that emergency teams would continue their search Friday morning.
