Increasing of fish productivity by finding suitable FADs placement locations based on Landsat 8 Imagery's analysis

Research output: Contribution to journalConference articlepeer-review


The main fishing ground of Pacitan Regency are Pacitan Bay and Indian Ocean. In addition to traditional methods, Pacitan fishermen also use Fish Aggregating Devices(FADs) to catch fish. The use of FADs in areas that have suitable water quality can further improve their production. The purpose of this study was to determine the effective of fish production at FADs locations, which are located in areas with appropriate oceanic conditions. This applies for both fishermen who use fishing rods and those who use FADs. The data collection method in this study used Landsat 8 Imagery, with parameters used in this study including temperature, current velocity, turbidity, salinity, depth and abundance of chlorophyll-a. The method used in this research was Spatial analysis with GIS technique. As for obtaining production data, an interview was conducted with fishermen. The results showed that fish production from fishermen using FADs was 400% larger than that of fishermen by traditional fishing methods. Areas that are oceanographically very suitable for FAD placement produce fish with better quality than those that are satisfactorily suitable-with more than 75% of its production is large pelagic fish.
