Supervision is an important action on the utilization of fishery resources in the sea in the context of realizing the preservation of fishery resources. Supervision actions must be carried out effectively by the Regional Government through officers who have been given obligations, such as the Indonesian National Armed Forces, the Navy, the Water Police and the Marine and Fisheries Service. Basically the supervision has been carried out by the officer, but the supervision has not been effective. This research was conducted by reviewing the supervision of illegal fishing for the preservation of fisheries in marine waters, and cooperation in supervision carried out according to the rule of law in order to realize the protection of marine fishery resources. The results of the study indicate that the supervisory action on the use of fisheries in the sea has not been running as it should, as well as the cooperation or coordination between the parties assigned the task of supervision has not been effective and the lack of coordination among these officers.
