THE UTILIZATION OF PENAEID SHRIMP RESOURCES IN CILETUH BAY, PALABUHANRATU BASED ON AREA SUITABILITY ANALYSIS
The utilization of penaeid shrimp resources in Ciletuh Bay, Sukabumi Regency is at high risk for overexploitation, since the area distribution of its penaeid shrimp is relatively narrow. Zoning-based management need to be implemented as an effort to manage its resources and to explain the function and width of an area for the utilization activities. The research aim to design an appropriate and measurable area of utilization based on the potency and its habitat characteristics spatially. Field and laboratory studies were conducted to collect and analyse the samples of catch and sediment. All activities conducted between February and April 2019. Purposive sampling methods used for sampling. The operation of trawl and Van Veen Grab were carried out to collect catch sample and sediment sample respectively. Spatial analysis was conducted on geographic information system (GIS) software to produce a utilization area by using inverse distance weighted (IDW) analysis and map algebra. The results showed two species of penaeid shrimp caught in its waters, namely dogol shrimp (Metapenaeus ensis) and jerbung shrimp (Fenneropenaeus merguiensis). Based on its habitat characteristics, the sediments of its waters categorized as silt. The waters categorized as most suitable (S1) was 209.254 ha or 43.7% of the total of the study area (479.288 ha). While the waters categorized as suitable (S2) was 209.067 ha (43.6%) and unsuitable (N) 60.967 ha (12.7%).
