The state-of-the-art, 207-foot-long tuna vessel, Sea Fox, is reporting a man missing overboard near American Samoa. The crewman was last seen aboard the vessel on Thursday. The Coast Guard and Sea Fox crew are conducting air searches for the missing man. It is not known whether the crewman was wearing a life vest or flotation device. Records indicate the Sea Fox is managed by South Pacific Tuna Corporation and United States Tuna Management Company, home-based in San Diego, California.
