Coastal Water Environment Suitability Studies for Green Mussel Cultivation in Pasaran Island, Lampung Bay

摘要

The green mussel cultivation by fishermen in Pasaran Island is influenced by nature and uses simpletechnology without regarding water conditions. In fact, site selection considering the water condition is oneof the important factors in determining the success of quality green mussel cultivation. High market demandbut not supported by modern technology, good marketing strategies, price stability, and appropriatecultivation site can reduce the production of green mussels. This research was conducted to determine theoptimal location for the green mussel cultivation around Pasaran Island, in Lampung Bay and to formulate amanagement strategy based on the map. Modeling parameters measured on the field include depth, salinity,pH, temperature, current velocity, dissolved oxygen, water clarity, and chlorophyll-a. Data processingmethods include inverse distance weighted (IDW) interpolations and fuzzy overlay. The study result in theform of raster-based physical water suitability maps for green mussel cultivation are intended to refine theuncertainties in the vector-based data presentation on water quality data so that it is expected to provideadditional information to avoid a less optimal cultivation environment so it maintain the quality of greenmussel products and support to accelerate aquaculture production raising program (minapolitan) in LampungBay.
