Shah Abbas I distrusted the local population and was not interested in maintaining the island as a trading centre or military post; instead he developed the nearby mainland port of Bander Abbas. Hormuz went into decline. Many of its inhabitants seasonally moved to their fields and orchards around the old Hormuz on the mainland, only fishermen being in permanent residence. The island continued to export small quantities of rock salt and lumps of iron oxide which were used as ballast stones for sailing ships.
