Application of Viirs-Dnb Satellite Data to Detect Ship Distribution Patterns, Fishing Activity Index and Planning Instrument of Pelagic Capture Fisheries in Bone Bay Waters

Bone Bay has long been used for fishing business. The fishing businesses are currently in small scale and large number of ships with a fleet reaches 12, 721 units per year and the weight of the ship measured between 3 - 30 GT. This research was aimed to detect fishing boat distribution pattern and determine fishing activity index (Ac) and develop fishing planning instrument using VIIRS-DNB data. The output data resulting from VIIRS-DNB interpretation will be very useful to estimate the fishing area based on the approach of ship distribution pattern aspect. The detection of fishing vessels arranged temporally in a still waters territorial will illustrate a pattern of fishing boat distribution and can be indicated as a habitat of fishermen conducting fishing operations. The results show that some regions had a similar temporarily pattern of fishing activity and had a high Ac value, including, Sinjai waters and sembilang islands, while other areas with high Ac were the Bone waters, Kolaka waters, northern of Luwu waters and some area in the southern part of Bone Bay regions with an Ac value ranging from 0.86 to 0.98. These area can be recommended as a fishing area based on approaches to aspects of previous fishing sites or habitual fishing grounds.
