Identification of coastal space for Vannamei shrimp (Litopenaeus vannamei) aquaculture based on geographical information system in Cempi Bay (Dompu Regency, West Nusa Tenggara)

Abstract

The research was conducted in February 2018 at the coast of Cempi Bay, Dompu Regency, West Nusa Tenggara. The objective of this research is to identify coastal area space to be utilized as vannamei shrimp aquaculture properly based on land carrying capacity. Data were analyzed using ArcGIS 10.2 software. Land carrying capacity and fisheries scale comparison data obtained in the coast of Cempi Bay were as follows: temperature (29.1 - 31.67 ° C), dissolved oxygen (3.84 - 5.9 mg / L), brightness (42.34 - 68 ), Nitrate (0.027 - 0.156 mg / L), phosphate (0.001-0.026 mg / L) and water pH 6,7-7,77). The land carrying capacity of Cempi Bay coastal land obtained from the overlay result consists of 2 Class conformity. Scores for the suitable land are 19835 with an area of 2699,480713 Ha and a fairly suitable land 285 with an area of 38,735236 Ha.
