Trent Jeremiah Simpson, 47, of Ebenezer died Sunday directly as a result of drowning and not preceded by some other condition, the RCMP say.
Queens District RCMP said that an autopsy was conducted today at the Queen Elizabeth Hospital in Charlottetown.
"Weather and tidal conditions are not believed to be a factor in this incident," said the force. "Foul play is not suspected."
The police report says Simpson was out with family members trying to get quahogs.
Simpson was located and retrieved from the water by witnesses late Sunday afternoon.
Resuscitation efforts were unsuccessful and he was declared dead at the scene.
