Five other crew, who reportedly jumped overboard Monday last week, remain missing.
Late on Thursday last week a search and rescue team involving the Fiji Navy, the New Zealand Air Force and LifeFlight Fiji located one of the survivors who was onboard a life raft.
The other two survivors had remained onboard the FV Tiro II and were picked up early on Friday morning by a partner fishing vessel, as the boat was sinking.
The three crew had been taken into custody, amid an investigation into an alleged murder on the vessel.
