Environmental And Area Support Capability Analysis For Seaweed Mariculture Development In Hading Bay Of East Flores Regency

Abstract: East Flores regency has adequate marine resources potentials to develop seaweed aquaculture area. Animportant aspect of seaweed aquaculture is the site selection. Site selection is based on the marine area extent and its ecological quality. The objectives of the study were to analyze the water ecology and its support capability and to determine the best site for continuous seaweed mariculture in Hading Bay of East Flores Regency. The study used descriptive method. It was conducted in Hading Bay, Lewolema District, East Flores Regency in March 2015. Data analysis was done using GIS based on area suitability value, and the method applied in the mariculture was long line method. Total Hading Bay water territory was864,676 ha. Site Awas135,345 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 units and seaweed territory capacity was 99%. Hading Bay waster has the capacity and area support capability for K. alvareziiseaweed 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.
