Identification of suitable location for expansion of fish aggregating devices (FADs) for fishermen on pacitan open sea, Indonesia

Pacitan Regency is located on the southern coast of East Java Province, Indonesia. The coastal area of Pacitan consists of a bay and open sea. Fishermen often catch fish with destructive fishing methods. FADs is a tool to increase fisheries production which is placed in a definite location. The purposes of this study were to find out the suitable area to expand FADs, to recognize the characteristics of fishermen, and to find out the benefits and readiness of Pacitan fishermen in using FADs. Fisheries production data was collected using interview techniques for fishermen and boats owners. The method for obtaining suitable location of FADs by using Geographical Information System (GIS) and remote sensing techniques. Parameters of temperature, pH, salinity, current and turbidity using Landsat 8 Image. While for chlorophyll-a by using NOAA imagery. Depth was obtained from the bathymetric map. The results showed that about 70% of sea in front of Pacitan coast is suitable for FADs expansion. In fact, only 10% of local Pacitan fishermen use Deep Sea FADs, and 10% use Shallow Sea FADs. Most FADs users in Pacitan are migrants. Development of Shallow Sea FADs is more profitable for local fishermen, because they can carry out one day fishing, low costs and reduce destructive fishing.
