Green mussel is one of important species cultured in Lada Bay, Pandeglang. ToÂ provide a necessary guidance regarding green mussel mariculture development,Â finding suitable site is an important step. This study was conducted to identify suitableÂ site for green mussel mariculture development using geographic information systemÂ (GIS) based models. Seven important parameters were grouped into two submodels,Â namely environmental (water temperature, salinity, suspended solid, dissolve oxygen,Â and bathymetry) and infrastructural (distance to settlement and pond aquaculture). AÂ constraint data was used to exclude the area from suitability maps that cannot beÂ allowed to develop green mussel mariculture, including area of floating net fishingÂ activity and area near electricity station. Analyses of factors and constraints indicatedÂ that about 31% of potential area with bottom depth less than 25 m had the mostÂ suitable area. This area was shown to have an ideal condition for green musselÂ mariculture in this study region. This study shows that GIS model is a powerful toolÂ for site selection decision making. The tool can be a valuable tool in solving problemsÂ in local, regional, and/or continent areas.
