Throughout the feudal era up until the early 1970s a traditional management system was in effect in eastern Indonesian areas. However, this system was steadily replaced by centralized government control. The Sasi system is considered as effective in protecting and conserving fisheries resources in the coastal waters of a community. The re-adoption of the system is supported by three elements: a well-established traditional community organization; an informal government endorsement of the Petuanan territory as a communal-property right; and an attitude of compliance and cultural value attributed to the familial relationships existing among fishers.
