An intensive three-day search for the 35-year-old was halted on Monday.
RCMP say the man was last seen cleaning the deck of the vessel during a trip to the Bella Coola wharf from the North Bentick Arm Channel last Friday evening.
He was seen on the boat at 5:30 p.m. and not noticed missing until about 6 p.m., when crew members began searching the area they'd covered before calling for help.
A team involving the coast guard, the Fisheries Department and two search and rescue aircrafts spent three days looking for the man but were unable to find him.
The case has now been handed to the RCMP, and police say foul play is not suspected.
