The prominent economic activity in Guraici Island region is fishing of highly economical coral reef fishes such as grouper, emperor, and others. The main problem emerged if fishing activity is extensive and uncontrolled that will threaten or degrade coral reefs fish resource in the area. The objective of this research was to analyze the fishing optimization model of pink ear emperor (Lethirinuslentjam, Lacepede 1802) resource the level of coral reef conservation area changes in Guraici Islands, South Halmahera Regency. This research was conducted in the waters of Guraici Islands from July to September 2015. The methods were experimental fishing and line transect. The results showed that the larger the area of coral reefs in the waters of Guraici Islands, South Halmahera Regency conserved, the lower the fishermen produced. This, however, led to emperor stock being abundant. MEY policy combined with coral reef conservation area protection policy provided more conservative variable indicator but provided positive economic rent compared to the combination of coral reef conservation area protection policy and open access policy.
