Tutuila is the largest island (145 sq. km) in the U.S. Territory of American Samoa. Tutuila has a population in excess of 60,000 people, with a large percentage of the total population of American Samoa living on this island. Pago Pago Harbor is one of the most protected harbors in the South Pacific and is home to a large fishing fleet, which brings fish to the tuna canneries that are one of the major industries and employers in the Territory. The safety of its harbor made Tutuila instrumental in World War I, when it was the center of the Samoan Defense Group, the largest of the Pacific defense groups. Until the end of the war, the territory was managed by the U.S. Navy from 1900 to 1951. Postwar, the territory was turned over to the Department of Interior and the first cannery opened in 1954. Tutuila has extensive banks (320 sq. km) surrounding the island that extend 1-9 km offshore. On the southwest side of Tutuila, Fagatele Bay is one of 13 National Marine Sanctuaries.
