Lobster aquaculture location selection based on oceanographic conditions using remote sensing (Case study: Ciletuh Bay, Sukabumi, Indonesia)

Abstract

Lobster (Panulirus spp.) is one of the marine resources that has high economic value, both locally and internationally. Ciletuh Bay has potential as a lobster cultivation location. The growth of lobsters is influenced by the conditions of the aquatic environment, especially the salinity and sea surface temperature. Remote sensing method can identify and analyse salinity and sea surface temperature. Salinity value obtained using Cilamaya algorithm, and sea surface temperature obtained using Syariz algorithm. This study aims to select a suitable location for lobster cultivation in Ciletuh Bay using a remote sensing approach. Map of salinity distribution and sea surface temperature is obtained from Landsat-8 imagery. The condition of water quality parameters in the Ciletuh Bay was quite suitable to be used as a lobster cultivation location. The distribution of salinity shows a dominance value 28.0-32.0, the distribution of sea surface temperature shows a dominance value 25.0-29.0, and the distribution of pH shows a dominance value 7.0-14.0. Based on the analysis of sea water quality parameters in Ciletuh Bay, most of the waters of Ciletuh Bay have a high suitability for lobster cultivation, covering an area of 253.01 ha.
