The study used descriptive method. It was conducted in Hading Bay, Lewolema District, and East Flores Regency in March 2015. Data analysis was done using Geographic Information System (GIS) based on area suitability value, and the method applied in the mariculture was long line method. Total Hading Bay water territory was 864,676 ha. Site A was135,345 ha, site B was 474,222 ha and site C was 255,108 ha. Area with S1 category was 729,331 ha extended in Site B and C. Area with S2 category was 135,345 ha as extended in Site A. Water territory support capability was 778,208 ha. The number of seaweed mariculture units was 194,552 and seaweed territory capacity was 99%. Hading Bay waters have the capacity and area support capability for K. alvarezii seaweed mariculture site. Site A was categorized S2 on suitability class and site B and C were categorized S1 on suitability class. The results showed different quality of water territory in those three sites was not significant and still in normal range of K. alvarezii seaweed mariculture development.
