The Chance-101 rolled over and sank Sunday in Japanese waters off Russia's Primorye Territory early Sunday with 30 people aboard.
Russia's Emergency Situations Ministry told the RIA Novosti news service a life raft with 10 survivors was recovered by a nearby ship.
Four surface vessels and a search plane continued looking for other survivors. Another aircraft was dispatched to the scene and would join the search Monday.
