He was fishing in an 18-foot skiff with his two teenage daughters when he went overboard while pulling in a net, said Coast Guard spokeswoman Sara Francis.
The Coast Guard has not released his name yet.
The accident happened in Togiak Bay around 9 a.m. A nearby fisherman immediately called for Coast Guard help. The skiff was only 10 to 20 yards from shore but the man was not wearing a life jacket.
A good Samaritan boat picked up the two girls from the skiff. They were reportedly fine.
Nearby fishing vessels looked for the man while the Coast Guard flew the three hours to the location. By the time the Coast Guard arrived, 15 vessels had been looking for the man.
A boat crew found the man's body on a nearby shore, Francis said.
"We don't know what happened," Francis said. "We don't know if he became entangled in the net, or it was the shock of the water, or if he swallowed a lot of water; there are lots of possibilities."
