Abstract: The complexity of the climate - ocean interactions in Indonesia is caused by the Indonesia's geographical position at the crossroads of the Indian and the Pacific Ocean. A periodic ENSO and non-periodic IOD affects Indonesian Monsoon system. A large volume of water masses from the Pacific Ocean that flows into the Indian Ocean passing through the territorial sea of Indonesia (Indonesian Through- flow) helps to provide a balance to the ocean climate in Indonesia as part their migration areas. For Tuna fisheries in Indonesia, Indian Ocean plays an important role for tuna's habitat. This article describes the physical condition of the South Eastern Indian Ocean based on archive data of the climate - sea survey, and also describes sustainable tuna habitat based on tuna catches surveys data. The southern part of Indian Ocean is a high primary productivity area for tuna because there is a periodic Java upwelling system occurred between June and October annually, and the eddy current system encourages nutrients and chlorophyll from the coast towards the open sea. This is an excellent ocean dynamics for the sustainable tuna fisheries.
