Abstract
One of the mollusc phyla and bivalve's class which is included in the group of invertebrate animals is the giant clam.Giant clams play an important role as filter feeders in the ocean and their clams can be used by various coral reef biota as a place to live.Therefore, it is necessary to manage clam cultivation considering the importance of the economic and ecological functions of the clam.Geographic information system is one method that can be used in this research.This method can be used to make it easier to find out the location of its distribution, so that the development of clam cultivation activities can be achieved optimally.The purpose of this study is to analyze the prospect of giant clam aquaculture using a GIS application which is presented in the form of a supply map for clam aquaculture in the West Lombok Sea.This research was conducted in May-June 2022 in Gili Asahan, Gili Layar and Gili Gede, West Nusa Tenggara Province.Data was collected using quantitative survey methods, in the form of primary data and secondary data directly related to the life of giant clams.The results obtained are: 28.25-31.13°Ctemperature, brightness 0.89-1.46m, current velocity 0.2-0.7 m/s, depth 0.89-1.46m, rainfall 56-364 mm, tides 0.9 m, protection: protected, moderately protected and unprotected, pH 6.82 -7.50, salinity 32-34 ppt, DO 6.19-6.52mg/l, sand dunes, fracture corals and dead corals, chlorophyll a 0.26-1.38mg/m 3 , and the number of clams 1-7 individuals.The location according to the land for the very suitable category is on Gili Gede, the appropriate category on Gili Asahan and the unsuitable category on Gili Layar.
