Four American victims, who were found relatively quickly after the crash, have also been identified as 46-year-old pilot Randy Sullivan, 62-year-old Cassandra Webb, 39-year-old Ryan Wilk and 46-year-old Louis Botha. The Coast Guard says 10 people were rescued after small boats and a helicopter were dispatched to the crash site.
The U.S. Coast Guard stated the nationalities of the deceased are 14 Americans, one Canadian and one Australian.
The body of Australian Simon Bodie, 56, was also recovered on Tuesday night.
All 14 passengers on both planes were from the cruise ship Royal Princess, on a seven-day trip from Vancouver to Anchorage and operated by Princess Cruises, the Washington Post reported.
The Coast Guard is leading the investigation into the collision, according to CNN.
The Royal Princess cruise ship, which left Vancouver bound for Anchorage on Saturday, is schedule to return to Vancouver on May 25. Part of the voyage, the company's website said, included "scenic glacier viewing" with stops at Juneau, Ketchikan and Skagway.
It's not known how the planes collided.
The Ketchikan-based operator of the larger plane, Taquan Air, said its pilot and nine passengers were rescued and receiving medical attention, but one passenger's fate was unknown. "Princess Cruises is extending its full support to traveling companions of the guests involved", Princess Cruises said in a statement.
Ten people from the aircraft were transported to the hospital. One of the wounded was in critical condition and three others were seriously injured, a spokesperson for Ketchikan Medical Center told a local CBS affiliate.
The other, operated by Mountain Air, carried guests from the ship but was an independent company whose tour was not sold through Princess, the cruise line said.
The Coast Guard has been leading the rescue operation with help from local volunteers, state police, firefighters, forest service workers and staff from the Alaska Department of Fish and Game.
"At this time, we are in the midst of an active crisis response, and our focus is on assisting these passengers, the pilot, our staff, their families and loved ones and first responders", Taquan said in a statement.
The National Transportation Safety Board said it was launching a "Go Team" to investigate the cause of the accident.
Global Affairs Canada said in an emailed statement Tuesday that the name and hometown of the victim is not being made public for privacy reasons.
A safety board official said they were due to reach the scene at about midday Tuesday.
In the aftermath of the tragic floatplane collision on Monday which involved cruise ship passengers the death toll has now risen to six.
The investigators will be collecting information from the survivors, the Federal Aviation Administration, any other witnesses who might have been in the area, flight logs, training records and other sources, including the wrecked planes, Homendy said. Neither plane was required by regulation to have such recorders, she said. The Beaver had been flying at a 3,300-foot altitude.
