A video uploaded to Facebook and verified by AFP showed a fisherman pulling a victim, still wearing her life jacket, from the water with a hook.
Another video showed what appeared to be a small child.
The confirmation of 11 new victims has thrown into confusion estimates of the number aboard the ferry when it sank.
A previous tally had placed the number of people missing at 10, including the ship’s captain, eight crew members and a safety marshal.
Philippine Coast Guard spokeswoman Captain Noemie Cayabyab told a local radio station the number of missing was now uncertain.
“Initially, the reported number of missing was 10 based on the [ship’s] manifest,” she said.
“However, we have received information from people that their loved ones are among the missing.”
Divers flown in from Manila arrived at the site to assist in the recovery efforts. An unmanned vehicle was first deployed to pinpoint the location of the wreckage.
The ship is understood to be lying at a depth of approximately 76m.
The Philippines grounded the passenger fleet of the ferry’s operator, Aleson Shipping Lines, pending what was described as a “full-blown investigation”.
One of the ship’s survivors described scenes of panic in the moments before the ship sank, with terrified passengers racing to one side of the listing vessel in a bid to rebalance it.
“No one from the crew alerted us,” 53-year-old lawyer Aquino Sajili told AFP, adding he believed it was likely that passengers would file a lawsuit against the shipping company.
